Abdomen with relatively weakly sclerotized preabdominal sclerites. Terga broad, sparsely greyish brown microtomentose, with fine setulae being longest at lateral margins. Preabdominal sterna somewhat broader than in female, densely finely setulose as also is pleural membrane. 5th sternum unmodified. Postabdominal sclerites well sclerotized, dark brown pigmented; 6th and 7th sterna strongly asymmetrical and fused together. 8th sternum relatively long, less asymmetrical, dorsally strongly convex and less densely microtomentose or partly bare. Genitalia (Figs 7,11) large and heavily sclerotized. Epandrium strongly convex, with the usual ventral lateral cleft (Fig. 7) and densely uniformly haired, without strikingly longer setae (in contrast to that of C. notabilis). Cerci distinct though fused with epandrium (Fig. 11 ) but medially separate (subanal plate reduced between cerci), each with 1 long sinuous hair-like seta and a number of fine setulae. Anal fissure subtriangular, relatively small. Medandrium (= intraepandrial sclerite) well developed (Fig. 11). Gonostylus (Fig. 7) convex posterolaterally, strongly tapered apically but its apex rounded (in contrast to that of C. notabilis - cf. Fig. 10) and covered by dense and long hair-like setae. Hypandrium (Fig. 7) with expanded convex lobes of lateral arms and robust anteromedial apodeme. Aedeagal complex (Fig. 12) of the C. notabilis-gioup type, closely resembling that of C. notabilis but differing as follows. Phallapodeme with small dorsal keel; phallophore with epiphallus more strongly curved ventrally and prc-epiphallus arising more distally; distiphallus with differently formed (less acute) and smaller paired dorsal hooks; postgonite with larger internal tooth being situated more proximally (Fig. 8) than that of C. notabilis (Fig. 9). Ejacapodeme very small and slender, situated in posterodorsal opening of phallophore (Fig. 12). Female. Head, thorax, legs and wing as in male except differences mentioned below. Total body length 4.76-5.24 mm. Fore femur more slender; mid femur and tibia without ventral sinuate hairs. Fore and hind basitarsus lacking small ventroapical hook. Wing measurements: length 3.09-3.26 mm, width 1.19-1.27 mm, C-index = 5.47-5.80, ta-tp : tp = 4.06-4.52. Abdomen. Preabdominal terga similar to those of male, 3rd-6th tergum relatively weakly sclerotized, brown to pale brown; syntergum 1+2 longest, darkest and most sclerotized preabdominal sclerite. Preabdominal sterna pale brown and narrower than in male. Setosity of postabdomen similar as in male. Postabdomen telescopically retractable, much narrower than preabdomen (Figs 4-5). Sclerites of 6th and 7th segment weakly sclerotized and pale pigmented, darkest along margins and bases of setae. These sclerites and also those of 5th segment and 8th tergum provided with 3 posterior tongue-shaped secondary sclerotizations of intcrsegmentary membrane. 6th tergum broader than 6th sternum (Figs 4-5), the later anteriorly rounded and both with fine setulae at posterior margin only. 7th tergum also larger than 7th sternum although both similar in shape. 8th tergum dark and heavily sclerotized and dorsomedially divided into two plates; its setulae scatered on entire disc. 8th sternum also dark and medially divided but distinctly shorter (Fig. 5) than 8th tergum. 10th tergum small, and strikingly narrow, elongately pentagonal but somewhat tapered anteriorly, dark pigmented, with 1 long and (usually) 3 short pairs of setulae dorsally. 10th sternum also dark and well sclerotized, broader than 10th tergum, convex ventrally and acutelly narrowed anteromcdially, with numerous fine hairs at posterior margin. Spcrmathecac (1 + 1) ball-shaped (Fig. 6), with dense and fine superficial striae, internally with a long straight apodeme opposite the duct opening, the latter being provided with distinct though short external collar. Cerci relatively short, darkly pigmented, with usual set of hair-like setae (Figs 4-5).
