Head yellow becoming darker dorsally on upper occiput, vertex and frons, ocellar protuberance black; setae black, similar to C. manggawna new species. Antenna with basal segments yellow; poped 2.5–3.0× long as wide, dark brown; stylus 2.0–2.5× long as poped, brown (yellowish white in some lights). Mouthparts yellowish but labellum black.

Thorax ( Fig. 21 View Figs ) yellow to brownish yellow, pleura paler; postpronotal area and mediotergite often darkened; scutum with dark median stripe (usually strongest anteriorly but very variable) and indications of sublateral stripes posteriorly. Chaetotaxy similar to C. manggawna new species, all setae black.

Legs yellow, tarsomeres 4–5 darker. C 1 0.95–1.0× as long as thorax; rather slender, 9.5x as long as wide, anterobasal setae not distinguished from regular row of yellowish anterior setulae. F 1 slightly longer than C 1, moderately slender, 6× as long as wide, rather evenly inflated below, widest 0.4 from base; femoral formula 5(5–5)/22(19–26)/14(12–18)/4(4–4) +1 ( Table 1), denticles black; spines yellowish or yellowish black, rather evenly spaced, becoming rather longer basally; basal spine distinct. T 1 short, less than 0.7× as long as F 1.

Abdomen brown, paler ventrally; tergites 7 and 8 reduced; apical abdominal segments with only short setae. Epan and Hypan fused ( Fig. 2 View Figs ), erect, narrowly subrectangular in lateral view, yellowish brown, only small setae posteriorly, left and right lamellae very narrowly separated my unpigmented membrane (hardly visible in unmacerated specimens). Cercus fused with Epan, brownish yellow, bilobed; upper lobe elongate digitiform, covered with numerous distinct setae of which three in distal part rather stronger and more erect, apically with rather dense ‘brush’ of minute upswept setulae; lower lobe emerging from inner face, very slender and gradually curved, yellowish with darker broader tip. Subepandrial process and postgonite slender, inconspicuous. Phallus broad, yellowish, sharply minutely upcurved apically with a small recurved dorsal ‘beak’ subapically.

Wing membrane faintly greyish, veins brown. Squamae yellow. Halter pale brown.

Female. Similar to male; antenna with poped almost 3x long as wide, stylus 2.0–2.5× as long.

F 1 slightly stouter; femoral formula 5(4–5)/24(19–28)/16(14– 20)/4(4–4).

Abdomen brown, yellowish ventrally with sternite 8 brown, rather elongate. Cercus elongate.

Remarks. – Thai specimens agree with the description and habitus figure in Brunetti (1920) although the male genitalia have not previously been figured and it has not been possible to examine the type material. The species is known from north eastern India, the western slopes of the Tenasserim Mountains in Myanmar ( Burma) and is here reported from the north (Chiang Mai), north eastern (Loei) and southern (Trang) provinces of Thailand. C. flavida was abundant on Doi Inthanon, mostly in mid elevation forest from 1,200 –1,700 m for most of the year with a major emergence peak from October – January and a lesser peak in July and August.
