Wing length 1.6-2.0 mm (♂), 2.0-2.3 mm (♂). Length of ultimate section of vein M4 divided by penultimate section: 2.1-2.9. Eye height divided by gena height: 1.8-3.6. First flagellomere with shallow angle on anterodorsal margin. Notum subshiny to heavily dusted.

Chaetotaxy: Two ori; two ors. Ocellar seta sometimes thinner and/or shorter than postocellar. Two well-developed dorsocentral setae, setula in front of anterior dorsocentral small to long and well-developed, sometimes reaching 2/3 length anterior dorsocentral. Six rows of acrostichal setulae. One posteromedial seta on mid tibia.

Colouration: Setae dark brown. Head yellow with back of head, clypeus, palpus, ocellar tubercle and antenna dark brown; frons brownish in posterolateral corner; lateral margin of frons sometimes either with narrow brown infuscation along fronto-orbital plate that occasionally extends to encompass base of fronto-orbitals, or with brown stripe extending from vertical setae to posterior or anterior ors; dorsal margin to dorsal 1/3 of face brown. Thorax dark brown with postpronotum (excluding dark anteromedial spot confluent with margin), notopleuron (excluding dark elongate sublateral spot) and small anterolateral spot behind suture yellow. Calypter white. Halter white. Legs and abdomen dark brown.

Genitalia: (Figs 470 View Figures 466–474 , 471 View Figures 466–474 ) Epandrium and surstylus with dense patch of tubercle-like setae on inner-distal margin. Hypandrium and postgonite as in C. humeralis . Basiphallus sclerotised along dorsal/left-lateral surface. Hypophallus with one pair of long, narrow sclerites approximately as long as basiphallus with irregular outline and small inner-basal process. Paraphallus rod-like with base wider and darker; diverging, angled anteroventrally; joined basally by narrow transverse sclerite. Mesophallus as long as basiphallus, slightly bulbous basally, with dark basal plate in front of point of duct insertion; small medial sclerite between mesophallus and distiphallus present. Distiphallus entirely divided into two short tubules, dark, very closely spaced; base stem-like (lateral view) and most of distal region broader, cup-like, angled slightly dorsally; inner fringed structure slightly emerging apically. Ejaculatory apodeme similar to that of C. platyptera .
