    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 https://github.com/xtmtd/ Phylogenomics/tree/main/scripts. The virtual mirror file (.vmdk) integrates the operating system and required environment. All tools and scripts can be downloaded from https://dx.doi.org/ 10.6084/m9.figshare.21283026. Besides, the video introduction and “walk-through” for each script are provided at https://space.bilibili.com/319699648/channel/seriesdetail?sid=2682055.

    Callosobruchus maculatus (Fabricius, 1775) (Coleoptera: Bruchinae) is a destructive agricultural pest that is harmful to beans worldwide and an important quarantine pest in China. It was divided into two phenotypes based on polyphenism: normal and flight forms. In this study, we first compared the morphological structures of the compound eyes of the two forms. According to the results of scanning electron microscopy (SEM), transmission electron microscopy (TEM), microcomputed tomography (micro-CT), and computer three-dimensional reconstruction, there are no differences in the structures of the compound eyes between the normal and flight forms except for the number of ommatidia. From the internal structure, the compound eyes have a biconvex cornea with open rhabdom and acone eye, crystalline cone directly connected with rhabdom, and no clear zone. It is a kind of apposition eye. Ommatidia facets range in shape from quadrilateral to hexagonal and some irregular shapes. On electroretinograms (ERGs), the normal and flight forms showed different spectral sensitivities: the normal form had the strongest response to ultraviolet light, whereas the flight form had the strongest response to white light. Behavioral assays revealed that the normal and flight forms showed completely opposite phototaxis behaviors; the flight form exhibited positive phototaxis, whereas the normal form exhibited negative phototaxis. This study not only enriches our knowledge on coleopteran compound eyes but also provides a foundation for in-depth research on the photoreceptor mechanisms of compound eyes, which may be useful in pest control management.

    Myxozoans are common microscopic endoparasites in fish, and some are highly pathogenic to their wild and farmed fish hosts. In the present study, myxosporeans infection in the kidney of silver carp Hypophthalmichthys molitrix (Valenciennes, 1844) from Lake Taihu, was investigated, and two dominate species, Myxobolus lieni (Nie & Li, 1973) and M. varius (Achmerov, 1960), with infection prevalence 60.2% and 35.2%, respectively, were well characterized based on morphological, histopathological and DNA sequence data. M. lieni formed small roundish plasmodia in the epithelial cells of renal tubules. The mature myxospores appeared suborbicular, slightly flat in frontal view and fusiform shaped in sutural view. Dispersed myxospores of M. varius were found in the renal interstitium without forming plasmodia structures and enclosed within melano-macrophage centers. The spore appeared elliptical in frontal view, with wider anterior than posterior and shuttle shaped in sutural view. Interestingly, the occurrence of myxozoans in the kidney detected with SSU rDNA PCR and clone sequencing, revealed co-infection of five Myxobolus species. BLASTn search indicated SSU rDNA gene sequences obtained here were not identical to any sequence available in GenBank. Phylogenetic analyses showed that the five Myxobolus species detected here were clustered together, forming a separate clade of cyprinid-infecting myxozoans.

    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.

    In this study, two new species of Typhloplanidae, viz Phaenocora shenda Huang & Wang, sp. nov. and Mesostoma jilinensis Wang & Huang, sp. nov. collected from northeastern and southern China, were identified and described through an integrative approach combining morphological, histological, and molecular (18S and 28S rDNA) data. Phaenocora shenda Huang & Wang, sp. nov. is morphologically characterized by the presence of an unarmed penis papilla, a genito-bursal duct and a burso-intestinal duct. The individual of P. shenda Huang & Wang, sp. nov. can be in green color or colorless, depending on whether it contains the endosymbiotic zoochlorellae or not. Mesostoma jilinensis Wang & Huang, sp. nov. is morphologically characterized by a relatively large penis papilla of the copulatory organ. A prepharyngeal pit is present. The paired uteri are connected to the common genital atrium. Phylogenetic analyses inferred from nuclear 18S and 28S rRNA genes have provided insights into the phylogenetic position of these two new species.

    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.

    Males of Platycnemis latipes (Platycnemididae, Odonata) have enlarged tibiae (fans) and patrol using a special longitudinal zig-zag flight. By means of focal observations and experimental manipulations of the colour of abdomen and fans of mature males, we suggest that the zig-zag flight is used to avoid unnecessary harassment from other males and has not the function to attract females. The fans of P. latipes are mainly used as a tool to threaten rivals, but their effectiveness seems limited. Both abdomen and fans of a mature male can reflect UV light strongly.

    The genus Limonia Meigen, 1803 is globally distributed with 216 known species/subspecies, of which 30 are recorded from China. In this study, we firstly use DNA barcodes (mt COI) to identify specimens of Limonia from China, result in a discovery of three species. Considering the morphological data, these species were identified as L. albiterminalis Lü, Ren & Zhang, sp. nov., L. juvenca Alexander, 1935 (new record in China), and L. macrostigma (Schummel, 1829), respectively. Six COI sequences of the three species were provided, analyzed with other 24 COI sequences from Limonia species. The result indicates that intraspecific distances in the genus are generally less than 2.2%, interspecific distances range from 7.9% to 17.2%, and there is no overlap between intra- and interspecific distances. Redescription and illustrations of L. juvenca and illustration of male hypopygium of L. macrostigma, as well as the key to the Chinese Limonia crane flies, are all provided.
