Amiota communis Chen and Steyskal A. durangoensis A. lineiventris Máca A. steyskali Máca. Revision Of The Nearctic Species Of The Genus Amiota Loew (Diptera: Drosophilidae) Jones, Lance E. Grimaldi, David A. Bulletin of the American Museum of Natural History 2022 2022-09-15 2022 458 1 181 89YBL 462269 Wahlberg 1839 [807,962,1578,1601] Insecta Drosophilidae Amiota Animalia Diptera 23 23 Arthropoda species alboguttata  DIAGNOSIS: Small to medium-sized flies; dark brown to black-brown, with typical white markings; aristal branches with short to long branches; frons faintly pollinose to silvery reflective; some species with comb on the hind tibia (  A. communisand  A. steyskali). Male genitalia: Outer paraphysis linear, simple (no spines); subepandrial sclerite large and recurved.  NEARCTIC SPECIES:  Amiota communisChen and Steyskal,  A. durangoensis, sp. nov.,  A. lineiventrisMáca, and  A. steyskaliMáca.  COMMENTS: This is a large species group established by Chen and Toda (2001), for what are now 48 Palearctic and Asian species. The group was defined morphologically, based on the male hind legs: tibia with a ventral row of long setae; tarsomeres 2–5 broadened, shorter than 1.5× the width. We have found that the short tarsomeres is a continuous character that is not well defined in Nearctic species. We are also proposing in the diagnosis above several male genitalic features that group the Nearctic and at least some of the Palearctic species. Wang et al. (2020)analyzed COI and ND2 sequences of the group; they did not include  A. communis,  A. steyskali, or  A. subtusradiataDuda.  Amiota subtusradiatawe classify into a separate group with two Nearctic species based on the distinctive genitalia.
