    The vampire squid, Vampyroteuthis infernalis Chun, 1903, is currently the only extant species in the family Vampyroteuthidae Chun, 1903. However, specimens from the Gulf of Guinea, Africa, and California suggested the possibility of additional taxa. Here, we report the second species of Vampyroteuthis, collected from the South China Sea, China, which differs from V. infernalis by its tail shape, lower beak, photophores position, and the phylogenetic analysis of mitochondrial COI and nuclear large subunit ribosomal DNA (LSU) sequences: V. infernalis present by the lacking of the tail, photophores located approximately one-third of the points between the fins and end, and the lower beak with a broad, short wing; V. pseudoinfernalis Qiu, Liu & Huang, sp. nov. present by an acuate tail, a pair of photophores located at the midpoints between the fins and tail, and a lower beak with a broad, elongate wing.

    Species are not only the fundamental units of taxonomy but also the basic units of pest management. Insects of Conogethes are important agricultural and forestry pests. However, species boundaries within Conogethes often appear obscure. In the present study, we re-evaluated the species status of Conogethes by applying three species delimitation approaches based on the mitochondrial DNA sequences, with particular emphasis on the yellow peach moth C. punctiferalis (Guenée, 1854). We first optimized species delimitation and inter-species genetic divergence threshold using a DNA barcoding dataset. The results revealed that several nominal species of Conogethes species harbored deeply diverged mitochondrial lineages which were recognized as independent species by the species delimitation methods. The p-distance between the delimited putative species ranged from 0.0159 to 0.1321 with a mean of 0.0841. Then we refined the species status of C. punctiferalis using the smallest interspecific distance threshold based on a geographically comprehensive population-scale dataset. This procedure narrowed the species concept of C. punctiferalis to a genetically coherent unit. Further investigation of its intraspecific divergence in the geographic context revealed that the refined C. punctiferalis was still widely distributed with the same or highly similar mitochondrial haplotypes occurring across South and East Asia.

    Each species within the order Thysanoptera has a distinct mitochondrial gene order displaying a high level of gene rearrangement, particularly massive in Phlaeothripidae. To understand the evolutionary patterns of rearrangement in this family, we sequenced the complete mitochondrial genome of Psephenothrips eriobotryae, a notable potential pest of loquat trees. Its mitogenome is a circular DNA molecule (15,413 bp in size) composed of 37 genes: 13 PCGs, 22 tRNAs, two rRNAs, and two putative control regions (CRs). By comparing with the ancestral mitogenome of arthropods, P. eriobotryae exhibits notable gene rearrangement variations. However, it shares four conserved gene blocks with three closely related species in Phlaeothripinae. In the phylogenetic tree, P. eriobotryae was clustered with these three leaf-feeding Phlaeothripinae species. The presence of more similar conserved gene blocks probably indicates a strong correlation between gene rearrangements and the phylogeny within Phlaeothripidae. Furthermore, the mitogenome of P. eriobotryae shows some characteristics: (a) two putative CRs in which CR2 is the copy of partial CR1 with 99.62% sequence similarity, and CR1 consists of two 237 bp repeat unites; (b) high A+T content of 82.6% in overall base composition; (c) trnS1 lacking a complete dihydrouridine (DHU) arm; (d) the protein coding gene, atp8 started with TTG instead of the more common ATN, while nad3 terminated by TAG rather than TAA; (e) translocations and inversions observed in fifteen of the 37 genes.

    Four species of the genus Karstsinnectes, which live in dark, low-energy groundwater ecosystems, are currently recorded, mainly distributed in the upstream of the Pearl River, the Youjiang River and the Hongshui River. Completing biodiversity surveys is particularly difficult due to the particular cave habitats inhabited by these species. In this work, we describe a new cave fish of the genus Karstsinnectes, namely K. cehengensis Luo, Zhao & Zhou, sp. nov., collected from the Beipanjiang River, the upstream of the Hongshui River. Genetically, the four individuals of the new species form a phylogenetically separate lineage, as the sister clade of K. acridorsalis, with a 9.4–9.5% genetic difference in mitochondrial Cyt b. Morphologically, the new species can be distinguished from its congeners by a combination of the following morphological characteristics: body naked, without body color; eyes reduced, diameter 1.4–3.8% of head length; anterior and posterior nostrils adjacent, anterior nostril not elongated to a barbel-like tip; lateral line incomplete; caudal fin forked; dorsal-fin rays iii-7, pectoral-fin rays i-11–12, pelvic-fin rays i-7, anal-fin rays iii-5, with 14 branched caudal-fin rays. The discovery of this new species represents the northernmost distribution of species within the genus Karstsinnectes and the first record from Guizhou Province. All currently known species of this genus inhabited in caves, making them ideal organisms for studying historical river connectivity and cave formation process.

    This study focused on and examined the traditional Lucanus fortunei group comprising more than 60% of all Lucanus taxa in China. Each species treatment includes a description, distribution, collecting methods, natural history and digital habitus and other pertinent images. A dichotomous taxonomic key was created specific to the Chinese L. fortunei group and the related groups. The Lucanus fortunei group is arguably the largest group in terms of species richness in Lucanus Scopoli; however, the group definition is unclear and needs to be critically assessed and redefined. Field work and sampling of the Chinese Lucanus fortunei species group was conducted between summer, 2017 and summer, 2022. Field sites included Anhui, Zhejiang, Fujian, Taiwan, Jiangxi, Hubei, Hunan, Guizhou, Sichuan, Chongqing, Yunnan, Xizang, Guangdong, and Guangxi Provinces. Thirty-two taxa (species and subspecies), including 473 specimens, previously considered to fall within the scope of the Lucanus fortunei group were examined by morphological study. Three new groups, the Lucanus brivioi group, the Lucanus kraatzi group, and the Lucanus parryi group are proposed and separated from the traditional Lucanus fortunei group, based on morphological characters. The subspecies, L. parryi laetus, is proposed as the synonym of the nominate subspecies.

    Phylogenomics is a new field that infers evolutionary relationships of taxa at the genome-scale level. The increment of molecular data may raise the potential bias as the limiting factor in phylogenomics. It is particularly important to explore these factors in phylogenomic analyses by simple, convenient, time-saving and (relatively) robust means. Here, we construct a set of custom scripts for USCO (universal single-copy orthologs) loci extraction, multiple sequence alignment, trimming poorly aligned regions, loci filtering and creating a concatenation matrix, prior to reconstructing the phylogenetic trees, to simplify analytical pipelines and improve the accuracy of tree estimation. These scripts employed a series of computationally efficient bioinformatic tools, and were used with a universal ‘BASH’ shell or visual interface by Windows-like ‘drag and drop’ operations in LINUX systems. Most steps in these scripts are parallelized to accelerate analyses. These new custom scripts provide a convenient analytical solution for phylogenomics data preparation, data quality control, and detection of potential analytical errors. Details and scripts usage are provided at Phylogenomics/tree/main/scripts. The virtual mirror file (.vmdk) integrates the operating system and required environment. All tools and scripts can be downloaded from 10.6084/m9.figshare.21283026. Besides, the video introduction and “walk-through” for each script are provided at

    The history of the Qinghai-Tibetan Plateau and the Himalayas (QTPH) region makes it a ‘living laboratory’ for understanding how the Earth’s abiotic evolution has shaped regional biotas. However, no studies to date have attempted to investigate general macro-scale biogeographical patterns and biogeographical affinities of the QTPH terrestrial fauna in a global context. Based on the analyses of the global distributions of QTPH Aphidomorpha species, we examined generalized distribution patterns for them and investigated the biogeographical affinities between the QTPH and other regions. Track analysis and cluster analysis of the global distributions of 298 Aphidomorpha species in the QTPH identified seven generalized biogeographical tracks and eight general distribution patterns. Both approaches detected similarly generalized distribution patterns. Four marginal areas where the generalized tracks intersect, i.e. the eastern Himalayas, the western Himalayas, the Hengduan Mountains, and the northeastern QTPH, were identified as biogeographical nodes. The generalized distribution patterns indicate the biogeographical affinities between the QTPH and other regions and suggest the complex nature of the QTPH fauna. A spatial congruence between the nodes and diversity centres detected by previous studies indicates the four marginal areas have been key areas in fauna evolution as centres for faunal exchange as well as glacial refugia. Based on the biogeographical patterns, the geological history of the QTPH and the evolutionary history of Aphidomorpha, we propose an evolutionary scenario for the evolution of the QTPH aphid fauna in which faunal exchanges, vicariance due to the uplift of geographical barriers, environmental heterogeneity and Quarternary glaciations have shaped the diversity patterns and fauna in the QTPH.

    Taxonomy plays an important role in understanding the origin, evolution, and ecological functionality of biodiversity. There are large number of unknown species yet to be described by taxonomists, which together with their ecosystem services cannot be effectively protected prior to description. Despite this, taxonomy has been increasingly underrated insufficient funds and permanent positions to retain young talents. Further, the impact factor-driven evaluation systems in China exacerbate this downward trend, so alternative evaluation metrics are urgently necessary. When the current generation of outstanding taxonomists retires, there will be too few remaining taxonomists left to train the next generation. In light of these challenges, all co-authors worked together on this paper to analyze the current situation of taxonomy and put out a joint call for immediate actions to advance taxonomy in China.

    A new newt species, Tylototriton daloushanensis Zhou, Xiao & Luo, sp. nov., is described from Guizhou, China, based on phylogenetic and morphological analyses. Phylogenetic analyses based on mitochondrial 16S and ND2 genes show that the new species is an independent lineage closely related to T. maolanensis, T. broadoridgus, T. dabienicus, T. anhuiensis, and T. wenxianensis. Morphologically, the new species is distinguished from its congeners by a combination of the following morphological characters: (1) large body size (SVL 64.7–83.6 mm in male and 70.5–100.3 mm in female); (2) head longer than wide, prominent bony ridges present; (3) snout rounded in dorsal view; (4) tail length less than snout-vent length in both males and females; (5) dark black body coloration, except for bright orange cranial region, palms and soles, vent region, and ventral ridge of tail; (6) relative length of toes III > IV > II > I > V; (7) fingertips reaching to between the eyes and nostrils when the forelimbs are stretched forward; (8) distal tip of the limbs greatly overlapping when the fore and hind limbs are pressed along the trunk; (9) presence of gular fold; (10) vertebral ridge slightly segmented, slightly flattened rib nodules, indistinct interspaces between rib nodules; and (11) lacking orange color markings on posterior parotoids and rib nodules. The found of the new species suggests that the species diversity of the genus Tylototriton may be underestimated.

    Gyrodactylus konovalovi is an ectoparasite on the Amur minnow (Rhynchocypris lagowskii) that is widely distributed in the cold fresh waters of East Asia. In the present study, the phylogeography of G. konovalovi and the distribution of its host in the Qinling Mountains are examined. A total of 102 parasite specimens was sequenced for the mitochondrial cytochrome oxidase subunit 1 (cox1) gene, and 43 haplotypes were obtained. The ratio of substitution sites (dN/dS) was 0.016 and indicated strongly purifying selection. Haplotype diversity (h) and nucleotide diversity (π) of suprapopulations of G. konovalovi varied widely between distinct localities from the Qinling Mountains. Phylogenetic trees based on Bayesian inference (BI), maximum likelihood (ML) and maximum parsimony (MP) methods and network analysis revealed that all haplotypes were consistently well-supported in three different lineages A, B, and C, indicating a significant geographic distribution pattern. There was a significant positive correlation between genetic differentiation (Fst) and geographic distance (P < 0.001). The results of mismatch distribution, neutrality test and Bayesian skyline plot analyses showed that lineages A and B underwent population expansion after the Last Glacier Maximum (LGM) during the Late Pleistocene, while the lineage C underwent population contraction during the Middle to Late Pleistocene. Based on the molecular clock calibration, the most common ancestor was estimated to have emerged in the Middle to Late Pleistocene. Our study suggests that a clearly phylogeography of G. konovalovi was shaped by climatic oscillation and geological events, such as orogenesis, drainage capture changes and vicariance, during the Pleistocene in the Qinling Mountains in central China.

    This paper summarizes the advances and challenges in spider taxonomy of China. A table comparing the number of valid genera and species in China, Europe and the world is provided. To date, the Chinese spider fauna is represented by 5,084 species, under 809 genera in 69 spider families. An “All Species Inventory” of spiders in Xishuangbanna Tropical Botanical Garden provides an example of China’s spider species richness, with more than 782 species recorded within a small area. Intensified research in recent years has grown the national catalog of Chinese spiders from 1,050 species in 1983 to 5,084 species today. There are reasons to believe that spider species richness in China will far exceed this grand total. With enhanced support and investment in spider taxonomic research, many more new species will be discovered and described in China

    The largest superfamily Entomobryoidea is one of the key groups in Collembola. However, incorrect recognition of chaetotaxic homology within Entomobryoidea severely impedes the accurate species comparison of adults and phylogenetic reconstruction. Traditional classification of the superfamily at suprageneric level is disputable in the light of recent advances. Transformational homology of tergal chaetotaxy was traced and revised based on 38 species of first instar and partial early instars. Morphological phylogenetic reconstructions were reconstructed mainly relying on first instar characters using both parsimony and likelihood-based algorithms. Outgroup selection and several rogue taxa impacted on resolution and support of otherwise well-supported clades. Integrating published molecular phylogeny, a revised classification of three families and nine subfamilies was presented: Orchesellidae, Entomobryidae and Paronellidae. Orchesellidae includes all basal taxa having a short fourth abdominal segment. Cyphoderidae and Microfalculidae taxa were sunk into Paronellidae. New Paronellidae was divided into two subfamilies: Paronellinae (Paronellini + Cyphoderini + Bromacanthini) and Salininae (Cremastocephalini + Callyntrurini). Microfalculidae (Microfalcula) was closer to Salina and Akabosia and thus transferred into Cremastocephalini. This study erected a new classification framework for Entomobryoidea based upon comprehensive phylogenies. Chaetotaxic homologization across a wide range provided a standardized, comparable, powerful tool for taxonomy.

    A new species of white-toothed shrew, Crocidura anhuiensis Zhang, Zhang & Li, sp. nov. is described from Mount Huang, China. Genetic sequence (mtDNA Cyt b gene) and morphological (external and skull) data are used to distinguish this newly discovered species. The phylogenetic analysis shows that the materials of this work are monophyletic and allied to C. attenuata by the uncorrected genetic distance 4.9–5.1%, which suggests a species-level divergence. Morphologically, the materials are different from C. attenuata by presenting a greater proportion of tail-to-body ratio and the presence of an obvious tooth root in the mandible. Based on those data, the unnamed species is described as a new species which is currently known only from the Wild Monkey Valley, Mount Huang, Anhui Province, China.

    A molecular study based on COI, 16S and 28S genes reveals that a batch of specimens (7 males and 4 females) of Dysphaea Selys, 1853 collected from central Vietnam, which include different color patterns of wings and body, and were originally identified as three different species, are all the same species. This study implies that, in some group of Odonata, identification only depending on color pattern may be unreliable, no matter what huge variations there are.

    The melon thrips, Thrips palmi Karny, is an economically important pest on many vegetables from Solanaceae and Cucurbitaceae. In this study, we developed novel microsatellite markers for Thrips palmi. First, we obtained randomly sequenced regions from the genome using next-generation sequencing and assembled 356 Mb genomic sequences. In total, 155,789 microsatellites were identified from the genomic sequences, of which, 64.02% were loci of dinucleotide repeat. Sixty primer pairs were initially validated in seven individuals. Thirty-five polymorphic markers were retained according to the amplification efficiency and polymorphism. These 35 microsatellite loci were then assessed in 96 individuals in four geographical populations collected from China. The allele numbers ranged from 2 to 19 with an average value of 6.9 per locus, while the polymorphism information content ranged from 0.2219 to 0.8490. The observed and expected heterozygosity varied from 0.5252 to 0.5367 and 0.5934 to 0.6148, respectively. Genetic structure was found between populations from southern and northern China. These novel microsatellite markers developed in our study provide abundant molecular markers for the genetic study of T. palmi.

    Double-digested Restriction Site Associated DNA Sequencing (ddRAD) through next-generation sequencing (NGS) generates large numbers of loci for characterizing genome-wide variation among multiple samples using next-generation sequencing. Different combinations of restriction endonucleases (REs) may produce varying size distributions of digested fragments, which affect the number of genotyped loci. Understanding digestion profiles across different species will help in selecting REs for digestion in a particular organism. In this study, we use of genome sequences to compare the in silico digestion profile of 26 combinations of REs in 131 insect species with two simulation programs. The number of digested fragments in the 300–450 bp range increases linearly with the size of the genome. Different species and insect orders showed similar profiles when digested by different combinations of REs in silico, indicating the conservation of digestion by double enzymes in insect genomes. Combinations with NlaIII or TaqαI usually produced higher number of fragments in the range 300–450 bp, while combinations with EcoRI or MluCI produced fewer fragments. The proportion of fragments with the same overhangs at the two ends of digested DNA was higher than those with different overhangs. The two four-base enzyme pairs produced more fragments in the 300–450 bp range than pairs of four-base + six-base enzymes. Experimental digestion of three species from Hymenoptera, Lepidoptera and Thysanoptera showed profiles congruent with in silico expectations. Our results shed light on understanding the digestion profiles of insect genomes and provide guidance on selecting REs for ddRAD projects.

    Few studies have explored the differences between Sanger and HTS methods in the results of mitogenome sequencing. We used a single individual of insect to study the differences between the sequences given by Sanger and PCR-free HTS methods. Here we provided evidence for biased results of sequencing due to different methods in the mitochondrial genes of atp6, atp8, cox1, cox2, cox3, Cytb, nad2, nad3, nad4, nad5, rrnS, rrnL, trnH, trnI, and control region at various degrees. Especially, in cox1, the differently sequenced nucleotides account for 2.6% of the complete length. Furthermore, the highest value of the intraspecific genetic distance based on K2P accounts for 2.5% using a barcode fragment size of cox1 (651 bp, Sanger), while the maximum distance of the corresponding cox1 fragment obtained by the two sequencing methods was 5.0%. We revealed that the methods of Sanger and HTS may give different sequencing results of mitochondrial genes, which may reflect the heteroplasmy of mitogenomes within an insect individual. Therefore, researchers should be very cautious in using the mixed data of a gene given by different methods of sequencing.

    In this study, the complete mitochondrial genomes of four pierid butterfly species, namely Batltia butleri, Talbotia naganum, Pontia callidice and P. daplidice, were newly sequenced and characterized. Meanwhile the phylogenetic relationships of the main Pieridae lineages covering 22 pierid butterfly species, were reconstructed with Bayesian inference and maximum likelihood methods based on different mitogenomic datasets, including the concatenated 13 PCGs, 13 PCGs + 2 rRNAs, 2 rRNAs, 2rRNAs + 22 tRNAs and 22 tRNAs sequences, respectively. Our results of mitogenomic analysis showed that the four mitogenomes were 15,124, 15,155, 15,109, 15,124 bp in size, with the gene orders and arangements identical to all other butterflies determined. Our results of phylogenetic analyses upon protein coding genes, rRNA genes or their sequence combinations indicated that the three pierid subfamilies of this study were all monophyletic, with their relationships of being (Dismorphiinae, (Pierinae, Coliadinae)); the phylogenetic relationship of Pierini of this study was (Pieris, (Baltia, (Talbotia, Pontia))) + (Prioneris, (Delias, Aporia)). Additionally, our analyses suggested that only mitogenomic tRNA sequence datasets were not ready to be utilized in resolving the deeper phylogeny, whereas somewhat suitable to be applied in clarifying the phylogenies of closely related species, of the pierid butterflies.

    Scarabaeinae is a globally distributed coprophagous coleopteran group with southeast Asia and Africa as the key areas of distribution. Located in the southern part of China, Hong Kong has subtropical climate and diverse habitats supporting a high diversity of scarabaeines. This paper gives a detailed review on Scarabaeinae from Hong Kong, including the new records to Hong Kong, photographic records of type specimens from Hong Kong, and identification keys to genera and species. A total of 13 genera and 51 species of scarabaeines were recorded in Hong Kong. Among them, 14 species were new records to Hong Kong found in the authors’ recent surveys, viz. Caccobius (Caccophilus) brevis Waterhouse, 1875, Copris (s. str.) punctatus Gillet, 1910, C. (s. str.) szechouanicus Balthasar, 1958, Microcopris propinquus Felsche, 1910, Onitis excavatus Arrow, 1931, Oni. intermedius Frivaldszky, 1892, Oni. subopacus Arrow, 1931, Onthophagus brutus Arrow, 1931, Ont. tricolor Boucomont, 1914, Ont. (Matashia) lenzi Harold, 1874, Ont. (s. str.) roubali Balthasar, 1935, Ont. (Parascatonomus) horni Balthasar, 1935, Scarabaeus (Kheper) erichsoni Harold, 1867 and Sisyphus (s. str.) indicus Hope, 1831. Onthophagus (Paraphanaeomorphus) trituber jacobsoni Kabakov, 2006 was found to be a new synonym of the nominate subspecies. Catharsius davidis Deyrolle & Fairmaire, 1878 and Copris davidis (Deyrolle & Fairmaire, 1878) were found to be the new synonyms of Catharsius molossus (Linnaeus, 1758). Hong Kong was also the only locality where Liatongus pugionatus and Onthophagus convexicollis were recorded over the world.

    Global species diversity is a historical result of speciation minus extinction and can be exhibited by phylogenetic patterns, whereas speciation is a process that may concern reproductive isolation and relating, at least in most sexual reproductive insects or other similar animals, to genital morphological evolution. The aedeagus is male genital organ that determines valid mating and reproductive isolation. However, definite correlation between aedeagus variation and species richness has not yet been clearly demonstrated. Here the phylogenetic tree of the rove beetle subfamily Staphylininae is built up based on 3085 bp DNA sequences of cytochrome oxidase subunit I (COI), nuclear 28S rDNA, nuclear genes wingless (Wg) and topoisomerase I (TP). Branching times and confidence intervals are calculated with molecular clock calibrations based on rove beetle fossil records. Different types of aedeagus, namely, median lobe plus a single paramere (Asp), a pair of parameres (App), or a single but bifurcated paramere (Abp), are marked on the phylogenetic tree and the genital morphological variations are compared in different genus-level taxa. The result shows that active cladogeneses occurred during late Cretaceous to late Paleogene, with those clades of Staphylininae evolved to be a more species-rich ones accompanied by larger aedeagus modifications. This implies that male genital morphological evolution might promote rove beetle speciation.

    In this study, the first complete mitochondrial genome (mitogenome) of lepidopteran family Drepanidae (superfamily Drepanoidea) was reported with the notes about its phylogenetic implications. The Oreta fuscopurpurea mitogenome is 15,564 bp in length, including 13 protein-coding genes, two ribosomal RNAs (lrRNA and srRNA), 22 transfer RNAs and a non-coding control region (AT-rich region), with a 79.6% A+T content. The gene orientation and arrangement of the mitogenome are the same as other sequenced lepidopterans. All protein-coding genes usually start with the common ATN codon except for COI gene, which used CGA as the initial codon; eight PCGs use a typical stop codon of TAA, whereas the remaining PCGs use incomplete stop codon of T or TA. All tRNAs have the typical clover-leaf structure with the exception of tRNASer (AGN). The lrRNA and srRNA genes are 1,409 bp and 778 bp in size respectively, with the former harboring one (TA)13 microsatellite-like repeat and an 17 bp insertion. The 20 intergenic spacers totaling of 184 bp and 8 overlapping sequences totaling of 25 bp are scattered throughout the whole mitogenome. The 526 bp AT-rich region contains some structures characteristic of lepidopterans, such as the motif ATAGA preceded by an 19 bp poly-T stretch, a tRNA-like and a sterm-loop structures. Phylogenetic analysis of the Oreta fuscopurpurea with other 47 insect species covering 20 lepidopteran families were conducted based on the sequence data of the 13 mitogenomic protein coding genes with maximum likelihood (ML) and Bayesian inference (BI) methods, and the results showed distinctly that the superfamily Drepanoidea was sister to the clade of (Bombycoidea, Lasiocampoidea) + (Noctuoidea, Geometroidea).

    Two spined loaches, Cobitis oxycephala Chen YX & Chen YF, sp. nov. and C. brachysoma Chen YX & Chen YF, sp. nov., are described based on specimens collected from Guangdong and Hainan Provinces, South China. Morphology features and sequences of mitochondrial cytochrome b gene of these two new species were analyzed. Morphological and molecular data show that C. oxycephala Chen YX & Chen YF, sp. nov. is closely related to C. dolichorhynchus Nichols, and C. brachysoma Chen YX & Chen YF, sp. nov. is closely related to C. microcephala Chen & Chen. These two new species can be distinguished from their congeners by the combination of characteristics of body shape, color pattern, lamina circularis, mental lobes, suborbital spine, subdorsal scales, and caudal peduncle.
