description: 2.2. Colocasiomyia cristata species complex, new
Diagnosis. Mid tibia with only 1 large, apical seta (ch.15-1; Fig. 7D). Male abdominal sternite VI with a pair of processes bearing prominent seta on apex and stout setae on submedial to distal portion (ch.26,27-1; Fig. 9G–K). Lateral pieces of subepandrial sclerite broad plates somewhat sclerotized at least on ventral margin (ch.37-4; Fig. 10D). Phallal sheath thicker than wide (ch.43-0; Fig. 11H,I).
Shared characters. Anterior reclinate orbital seta small, situated behind proclinate orbital seta; additional, interfrontal setulae on fronto-orbital plate present (ch.2-0; Fig. 3F). Eye with stout, dense interfacetal setulae (ch.3- 1; Fig. 3H). Distance between antennal sockets narrower than half of socket width (ch.4-1; Fig. 3G). Cibarial, medial sensilla in parallel rows narrower than sensilla campaniformia (ch.5-2; Fig. 4B). Neither additional dorsocentral setae on presutural area nor prescutellar acrostichal setae present; acrostichal setulae in 4 rows (ch.8-1, 9-0; Fig. 5C). Katepisternal setae small, shorter than postpronotal setae (ch.10-1; Fig. 5F). Basal scutellar setae long; posterior tip beyond half of apical scutellar setae (ch.11-1; Fig. 5C). Apical scutellar setae nearer to each other than to basal scutellar seta (Fig. 5C). Costal setae in middle row all weak, trichoid (ch.12-2; Fig. 6C). Patch covered with only minute pubescence absent on anterodorsal portion of fore tarsomere I (ch.13-1; Fig. 7B). Male abdominal sternite V medially concaved on posterior margin. Female abdominal sternites III and IV longer than wide (ch.19,20-1). Male abdominal sternite VI not pubescent at least partly (ch.23-0; Fig. 9G–K). Epandrial phragma small (narrower than epandrial anteroventral corner) expansion on antero-subapical margin (ch.33-2; Fig. 10C). Surstylus vestigial, very narrow process, apically with 1 or 2 tiny, trichoid seta(e) (ch.34,35-1; Fig. 10E). Median piece of subepandrial sclerite broad, somewhat quadrate plate (ch.36-0). Cercal, ventral/apical portion more or less differentiated from upper portion (ch.38-0; Fig. 10C). Phallal sheath not pubescent, gently curved ventrad, projected anteriad at dorsobasal corner in lateral view, apically not bilobed (ch.40-1, 41-3, 42-0, 44-1; Fig. 11H). Gonocoxites long, narrow slips (Fig. 11H). Epiproct with pubescence (Fig. 12C).
Included species. Colocasiomyia cristata, C. sulawesiana, C. kinabaluana sp. nov., C. kotana sp. nov. and C. matthewsi sp. nov.
