A. Key to the extant genera of the subfamily Exothecinae Haliday (modified from Belokobylskij, 1984, 1994b, 2000; van Achterberg, 1983) 1. Prepectal carina present in front of precoxal sulcus; occipital carina complete dorsally and area in front of it rugulose; frons with crenulate median groove; precoxal sulcus very wide............................ Orientocolastes Belokobylskij, 1999 - Prepectal carina completely absent (Fig. 2F); occipital carina usually absent dorsally, if present then area in front of it smooth (Figs 3A, 4C); frons without crenulate median groove; precoxal sulcus absent or narrow (Fig. 2F); but distinctly developed in Colastes (Discolastes Belokobylskij, 2000)................................................................ 2 2. Pronope absent or small, shallow and transverse, rarely medium-sized; clypeus convex............................. 3 - Pronope present, large and deep (Fig. 3F); sometimes obsolescent in Xenarcha; clypeus flattened..................... 4 3. Metasomal tergite V markedly enlarged, bent posteriorly and concealing subsequent tergites; tergites I–V entirely sculptured; male without occipital carina, but large temporal tubercles developed; malar suture distinct.................................................................................................... Vietcolastes Belokobylskij, 1994 - Metasomal tergite V normal; tergites II–V either smooth or sculptured; in both sexes occipital carina developed and temporal tubercles absent; malar suture indistinct or obsolescent..................................... Colastes Haliday, 1833 4. Tergites I–III forming a carapace-like metasoma, coarsely longitudinally striate, and their epipleura less sclerotised than their nota; remaining tergites covered by tergites I-III or largely so; tergite III on posterior margin with more or less distinct transparent border........................................................... Colastinus Belokobylskij, 1984 - Tergites I–III not forming a carapace-like metasoma, with their epipleura and nota equally sclerotised; remaining tergites distinctly exposed, tergite III along posterior margin without transparent border................................... 5 5. Occipital carina complete, ventrally reaching up to base of mandible (Figs 3A, 4C, 6A–E); first subdiscal cell of fore wing elongate (Figs 5B, 5D); fore wing vein 1-M of male widened, as wide as or wider than the length of vein cu-a (Fig. 5D)...................................................................................... Occipitotus gen. nov. - Occipital carina incomplete, dorsally interrupted; first subdiscal cell of fore wing broad; fore wing vein slender.......... 6 6. Metasomal tergites I–V entirely sculptured; apical tergites not protruding (or only slightly) beyond tergite V; tergites IV and V with a lateral crease.................................................... Pseudophanomeris Belokobylskij, 1984 - Metasomal tergites less sculptured, at most tergite III completely and base of tergite IV sculptured; apical tergites distinctly protruding beyond tergite V; tergites IV and V without a lateral crease........................................... 7 7. Posterior half of notauli absent or obsolescent; vein r of fore wing usually departing between basal third and base of pterostigma; if departing near basal 0.4 of pterostigma, then vein m-cu of fore wing distinctly converging to vein 1-M posteriorly................................................................................. Shawiana van Achterberg, 1983 - Posterior half of notauli distinctly impressed, (nearly) complete; vein r of fore wing departing from basal 0.4–0.6 of pterostigma and vein m-cu of fore wing less converging posteriorly....................................
