Molecular phylogenetic analysis of the Amiota taurusata species group within the Chinese species, with descriptions of two new species.
Bottom Line: A mitochondrial gene, cytochrome c oxidase I ( COI), can be used to discriminate between species of the taurusata group.Two new species are described from South China: A. protuberantis Shao et Chen, sp. nov. and A. shennongi Shao et Chen, sp. nov.A key to all the species of the taurusata group based on morphological characters is provided.

Mentions: The Amiota taurusata Takada, Beppu, & Toda (Diptera: Drosophilidae) species group was established by Chen and Toda (2001) based on a phylogenetic analysis using 31 adult male morphological characters. Until now, eight species have been reported in this group from East Asia (Chen and Toda 2001; Chen et al. 2004, 2005; Cao et al. 2008): A. aquilotaurusata Takada et al., 1979, A. asymmetricaChen et Takamori, 2005; A. femorataChen et Takamori, 2005, A. sacculipes Máca et Lin, 1993, A. spinifemora Li et Chen, 2008, A. taurusata Takada et al., 1979, A. vulnerablaChen et Zhang, 2004, and A. yixiangensisChen et Takamori, 2005. Chen and Toda (2001) regarded the taurusata group as monophyletic on the basis of the hind femur basoventrally with a small, lobe-like flap (ch. 1; Figure 2D in Chen and Toda 2001); hind tibia apicodorsally much extended flap (ch. 2; Figure 2D in Chen and Toda 2001); hind first tarsomere dorsally expanded (ch. 3; Figure 2D in Chen and Toda 2001); fourth tergite laterally broadened and protruded more than others (ch. 4; Figure 1B in Chen and Toda 2001). However, Chen et al. (2004, 2005) and Cao et al. (2008) found that the ch. 2 and ch. 3 are usually absent in some species; these two characters have been eliminated from the diagnosis criteria of the taurusata group.
