Holotype. Male (dried, pinned specimen CT-399 figured), PNG (south-east Oro Province), (Mau Island), Mount Suckling , 500 m, about 9° 42' S, 149° 02' E, at light, 11 July 1972, J.L. Gressitt ( BPBM). GoogleMaps

Diagnosis. The male of C. projectura can be separated from all other New Guinea species by the distinctive meso-dorsal projection on the inferior appendages.

Description. General body colour and wings light brownish. Wings similar to those of C. ukarumpana (fig. 7). Length of forewing: male 4.3 mm. Forewing with forks 1, 2, 3 and 5 present, Rs moderately sinuous or curved, moderately thickened basad of discoidal cell.

Male. Segment IX anterior margin in lateral view, with broadly rounded extension ventrally (fig. 29); ventral process a short slender projection distally tapering slightly, in length short of distal margin of segment IX (figs 29, 30), in lateral view length about 3 times width; preanal appendages rounded apically (fig. 29). Segment X laterally compressed, platelike, apices acute, with sensilla not obvious (fig. 31), in lateral view, lateral lobes robust, tapered distally (fig. 29), in dorsal view lateral lobes slender distally (fig. 31). Phallus with one slender spine included subapically (fig. 29). Inferior appendages robust, tapered distally with acute apices (figs 29–31), in lateral view aligned horizontally, length about equal to width, ventral margin convex, dorsal margin with finger-like dorsal projection (fig. 29), in ventral and dorsal views broadest in basal half, dorsal projection angled meso-dorsally (figs 30, 31).

Female. Unknown.

Etymology.Projectura –Latin for projection (inferior appendages).
