Key to the Oriental Genera of Teratomyzidae

1. Subscutellum distinct, rather deep and well sclerotised medially. Palpus developed (sometimes small). Often more than 2 pairs of dorsocentral setae............................................ (Genera in the Neotropical region and Australia)

- Subscutellum absent or very low. Palpus minute or apparently absent. Two pairs of dorsocentral setae................... 2

2. Wings unicolorous ( Fig. 111 ). Vein R2+3 not approximated to costa. Vertical callus not developed on head. Male surstylus long with narrow base ( Figs 11, 13 ) and without short thick blunt black teeth (pegs). Sclerotised duct of spermatheca thin and at least as long as spermatheca ( Figs 29, 31 ). One pair of katepisternal setae.................... Teratomyza Malloch, 1933

- Wings patterned ( Figs 112–121 ). Vein R2+3 approximated to costa, at least in its middle section. Head with or without vertical callus. Male surstylus with broad base and apically, or apically and caudally, with short thick black teeth (e.g. Figs 36 , 103 ). Spermathecal duct different. One or 2 pairs of katepisternals................................................... 3

3. Frons dull and striped. Head without vertical callus but vte and vti emerge on small protuberance. First flagellomere short and spherical; scape short. Wings sub-shining, basic colour brown with numerous light spots ( McAlpine & Keyzer 1994: fig. 36). Two pairs of katepisternal setae. Ejaculatory apodeme ( Fig. 7 ) robust with a high sagittal ridge. Two minute onion-shaped spermathecae (0.03–0.035 * 0.02–0.022 mm) with 3 apical projections ( Fig. 8 ). Australia.................................................................................................... [Vitila McAlpine & de Keyzer, 1994]

- Frons shining, without stripes. Head with a pair of vertical calli. First flagellomere and scape sometimes elongate. Wings shining, mostly dark with clear “window” distal to apex of R2+3 below costa ( Figs 112–121 ). Only 1 pair of katepisternal setae. Ejaculatory apodeme (e.g. Figs 34 , 49 ) without a large sagittal ridge and distal regon narrow. With 2 large spherical or ovoid spermathecae with measures of c. 0.14 x 0.12 mm; sclerotised part of duct thick, short and spinulose/textured ( Figs 80–83 ). (Oriental region, incl. China and Japan................................................... Poecilovitila gen. nov.
