Abstract
Two new species of the genus Homidia Börner, 1906 are described from Hubei and Anhui provinces, China. Both species resemble the type species H. cingula Börner, 1906 in color pattern, but are morphologically and molecularly distinct. H. qizimeiensis Wang, Lu & Zhang, sp. nov. is distinguished by a rectangular patch on the postero-middle of Th. III and the presence of macrochaetae (mac) m3a on Abd. II and a2 on Abd. III, which are absent in both H. cingula and H. bichaeta Wang, Lu & Zhang, sp. nov. H. bichaeta Wang, Lu & Zhang, sp. nov. is defined by a dark transverse band on the antero-middle of Th. III, the presence of only two posterior mac (B4 and B5) per side on Abd. IV, and 2+2 posterior smooth setae on the ventral tube. In comparison, H. cingula lacks the dark transverse band on Th. III and possesses 4–5 posterior mac (A5, A6, Ae7, B4, B5) per side on Abd. IV and 3+3 posterior smooth setae on the ventral tube. H. qizimeiensis Wang, Lu & Zhang, sp. nov. differs from H. bichaeta Wang, Lu & Zhang, sp. nov. by having four posterior mac (A5, A6, B4, B5) per side on Abd. IV and 3+3 posterior smooth setae. Comparative chaetotaxy combined with COI data supports the recognition of both new species.
