Eudmeta Wiedemann, 1830: 43 View in CoL — Brauer, 1882: 68 [key]; Bigot, 1891: 281 [catalogue]; Brunetti, 1920: 41 [revision], 1923: 87 [key, revision]; James, 1975b: 30 [catalogue]; Woodley, 1989: 314 [catalogue], 2001: 166 [catalogue]; Yang et al., 2010: 330. Type species: Hermetia marginata Fabricius, 1805: 63 View in CoL , by monotypy.

Toxocera Macquart, 1850: 348 . Type species: Hermetia limbiventris Fabricius, 1805: 63 , by original designation.

Diagnosis. Scutellar and notopleural spines absent; wing vein M 3 present; M 4 arising on discal cell, cross-vein r–m present; wing straight, not bent over abdomen; face flat; male eyes contiguous medially; eye not pilose; postocular ridge carinate in female, male narrowly carinate; antenna greatly elongate, scape much shorter than flagellum; flagellum cylindrical, circular sensory pits on flagellomeres I–III, flagellomeres IV–V very short and of similar length, flagellomeres VI–VII longer and of similar length; flagellomere VIII longer than all other flagellomeres, usually covered with deeply plumose microtrichia; abdomen ovoid in both sexes.

Comments. Eudmeta contains three species ( Woodley 2001; Yang et al. 2010) and is differentiated from other clitellariine genera in these regions by the following characters: absence of a nose-like process on the face, absence of scutellar spines (shared with Lagenosoma and Ruba ) and notopleural spines, wings straight (bent over abdomen in Octarthria ).

Examination of specimens of the relatively recently described Eudmeta coerulemaculata Yang Wei et Yang, 2010 , indicate that it is a synonym of the widely distributed E. marginata and that differences between the two species outlined by Yang et al. (2010) are colour differences attributable to variation in preservation condition and age of specimens; live specimens of both species appear identical. Comparisons of morphology of the male genitalia of both species also supports that they are the same species. In E. marginata and E. coerulemaculata (see Yang et al. 2014: fig. 181) the gonostylus is similarly forked with one arm shorter than the other, while in, for example E. diadematipennis , the gonostylus is not forked (see Yang et al. 2014: fig. 182). Two Eudmeta species are endemic to India, while E. marginata is widely distributed throughout Southeast Asia, including southern China, India and extending as far east as central Indonesia.

Included species. Eudmeta brunnea de Meijere, 1904 ; E. diadematipennis Brunetti, 1923 ; E. marginata ( Fabricius, 1805) (= E. coerulemaculata Yang, Wei & Yang, 2010 syn. n.).
