description: 5) Colocasiomyia sulawesiana Okada & Yafuso, 1989
(Figs 9I, 15E, 20)
Colocasiomyia sulawesiana Okada & Yafuso, 1989: 48.
Diagnosis. A pair of processes on male abdominal sternite VI short (<0.05 mm), nearly parallel and straight (Fig. 9I). Phallal sheath apically vertically dilated in lateral view, subapically with a pair of small, triangular flaps (Fig. 20D).
Supplementary description (not repeating characters common to C. cristata). Supracervical setae 5–9 per side. Cibarial, medial sensilla approximately 2 per side. Supralateral seta outside prementum approximately 5 per side. Male abdominal sternite III longer than wide; IV posteriorly slightly widening (Fig. 20A). Female abdominal sternite VI as wide as long, medially concaved on posterior margin (Fig. 20B). Epandrium with 1–3 setae on lateral to dorsal portion and 22–23 setae thicker than cercal setae on ventral portion of each side (Fig. 20C). Cercus with approximately 34–39 setae (Fig. 20C). Oviscapt distally slightly curved ventrad, longer than phallus (apodeme + sheath), with 20–22 ovisensilla but no patch of pubescence (Fig. 20F). Puparium (3rd instar larva): segments with stout spicules on ventral surface; anterior spiracle sessile, with a bundle of approximately 4 short branches; caudal segments elongate, with many small spicules, ending in a V-shaped pair of posterior spiracles (Fig. 20G,H). Mouth hook less expanded medioventrally in lateral view; distal blade as long as basal portion, apically pointed, weakly curved downward, with two rows of small, acute teeth on submedial to subapical portion of ventral margin (Fig. 20I).
Specimens examined. Indonesia: 50♂, 37♀, Enrekang, South Sulawesi, 6.i.2005, ex Alocasia macrorrhizos (L.) G. Don, K. T. Takano leg.; 26♂, 22♀, ditto except 8.i.2005 (MZB, SEHU).
Distribution. Sulawesi (South Sulawesi).
Remarks. Some original descriptions by Okada & Yafuso (1989) should be revised as follows. Okada & Yafuso (1989) described, “Second tarsal joint of fore leg protruded, with about 5 black teeth in 2 rows”, but illustrated four teeth in “ Fig. 1 ” and mentioned, “second tarsal joint of fore leg with about 4 teeth”, in the paragraph of ‘ Relationships ’. The latter state should be correct, because all the specimens examined in this study have four pegs on the fore tarsomere II without any exception. The original descriptions of “male 6S laterally divided, without protuberances” and “Surstylus absent” may be due to overlook of these small or vestigial organs in this species.
