E61F577E880FC24995EEFAA3CEF7FD8C.taxon	etymology	Etymology. The name “ fusciventris ” is a combined Latin noun, “ fuscus ” + “ venter ”, referring to the dark, blackish-brown metasomal terga.	en	Zhang, Dan, Niu, Ze-Qing, Orr, Michael C., Ascher, John S., Zhu, Chao-Dong (2020): Chinese species of Nomia (Gnathonomia) Pauly, 2005 (Hymenoptera: Apoidea Halictidae: Nomiinae).

E61F577E880FC24995EEFAA3CEF7FD8C.taxon	discussion	Remarks. We describe N. fusciventris sp. nov. as a new species of subgenus Gnathonomia in this study. Male of this species is similar to N. pieli and N. radiata (Pauly, 2009), the latter not examined but evaluated based on images from Atlas Hymenoptera (http: // www. atlashymenoptera. net / pageasp? ID = 136). We found that the two abovementioned previously-described species have basal hair bands on T 3 – 4, while the new species has apical hair bands reduced, and restricted to lateral edges. In addition, Nomia pieli can be distinguished from N. fusciventris sp. nov. by basal hair band form as given above. In addition, these species differ in genitalia, i. e. N. fusciventris sp. nov., has a penis valve with hooked projection basally, whereas the penis valve of N. pieli lacks a projection basally. The shape of S 7 and S 8 of N. pieli and N. fusciventris sp. nov. also differ (Fig. 2, Fig. 11). Further study, preferably informed by molecular diagnostic characters, is necessary to associate the unknown female of this species.	en	Zhang, Dan, Niu, Ze-Qing, Orr, Michael C., Ascher, John S., Zhu, Chao-Dong (2020): Chinese species of Nomia (Gnathonomia) Pauly, 2005 (Hymenoptera: Apoidea Halictidae: Nomiinae).

E61F577E8804C24195EEF94FC91EFE88.taxon	discussion	Remarks. We follow Pauly (2009) in treating N. thoracica, the most widely distributed and commonly collected subgenus Gnathonomia, as a single variable species. Many specimens from China are considerably larger than those from tropical sites, such as Singapore, and there is also significant allometric variation in the protuberance of the male clypeus. Further study, preferably including molecular diagnostics, is needed to assess the status of geographic forms of this species or species complex form, including populations from China and from Philippines with available names N. melior and N. stantoni respectively.	en	Zhang, Dan, Niu, Ze-Qing, Orr, Michael C., Ascher, John S., Zhu, Chao-Dong (2020): Chinese species of Nomia (Gnathonomia) Pauly, 2005 (Hymenoptera: Apoidea Halictidae: Nomiinae).

China (Jiangsu, Shanghai, Zhejiang), thus seemingly endemic to eastern China. Floral association. Unknown. Remarks. Male is described for the first time here. This species was described from the female only by Cockerell (1931 a) in a paper on many new bee species from China collected by Rev. Octave Piel. We examined the specimens deposited in IZCAS, including male and female, with matching collection information. The male of this species is very similar to N. radiata (Pauly, 2009), and Pauly said the female of that species is difficult to distinguish from the female of N. pieli. As we did not examine specimens of N. radiata (Pauly, 2009), future integrative taxonomic studies are needed to assess the status of those two species.	en	Zhang, Dan, Niu, Ze-Qing, Orr, Michael C., Ascher, John S., Zhu, Chao-Dong (2020): Chinese species of Nomia (Gnathonomia) Pauly, 2005 (Hymenoptera: Apoidea Halictidae: Nomiinae).
