( Figs 3E–H View FIGURE 3 , 4B View FIGURE 4 , 5C,F View FIGURE 5 , 6C View FIGURE 6 , 7B,D View FIGURE 7 , 9G View FIGURE 9 , 10C–E View FIGURE 10 , 11H,I View FIGURE 11 , 12C,D View FIGURE 12 , 15D View FIGURE 15 , 19 View FIGURE 19 )

Colocasiomyia cristata de Meijere, 1914: 273 View in CoL ; Duda, 1924: l77; Okada, 1988: 35.

Diagnosis. A pair of processes on male abdominal sternite VI long (> 0.05 mm), slightly divergent and curved inward ( Fig. 9G View FIGURE 9 ). Phallal sheath apically looking like arrowhead in ventral view ( Fig. 11I View FIGURE 11 ).

Supplementary description. Supracervical setae 6–9 per side, nearly straight, as long as inner occipital setae ( Fig. 3E View FIGURE 3 ). Cibarial, medial sensilla 2–3 per side; posterior sensillum 1 per side ( Fig. 4B View FIGURE 4 ). Supralateral seta outside prementum 4–5 per side ( Fig. 19B View FIGURE 19 ). Anterior dorsocentral setae just beside transverse suture ( Fig. 5C View FIGURE 5 ). Male abdominal sternite III as wide as long; IV wider than long ( Fig. 19C View FIGURE 19 ). Female abdominal sternites IV–VI longer than wide ( Fig. 19D View FIGURE 19 ). Epandrium pubescent except for anterior margin and anteroventral elongation, roundish on posteroventral margin, with approximately 2 setae on dorsal portion and 23–24 setae thicker than cercal setae on ventral portion of each side ( Fig. 10C View FIGURE 10 ). Cercus pubescent on dorsal half but not on anterior margin and ventral portion, extended below, slightly constricted ventrosubapically in lateral view, with approximately 42 setae ( Fig. 10C View FIGURE 10 ). Phallapodeme less sclerotized thin plate, nearly perpendicular to phallal axis ( Fig. 11H View FIGURE 11 ). Hypoproct not pubescent ( Fig. 12C,D View FIGURE 12 ). Oviscapt gently sinuate, as long as phallus (apodeme + sheath), apically round, with patch of pubescence on subdistal portion and 20–21 ovisensilla only on distal portion occupying less than 1/2 length of oviscapt ( Fig. 12C View FIGURE 12 ).
