Diagnosis ( Figs 14, 15 , 26, 27 ). Forewings above with pattern similar to C. fumipennis , but brown to olivebrown, with greyish scales, without bright yellow or orange lines or bands, with subbasal band rather broad, sometimes hardly distinguishable from the median band, without an inwardly directed subbasal notch, with median band broad for the genus, broad at the hind margin, edged with partly broken, thin whitish, olive-brown and ochreousbrown lines, with a shallow medial projection outwards and an almost inconspicuous inwardly directed postmedial streak near the costal margin, with an inconspicuous elongate oval discal dot, without a whitish subterminal line. Hind wings in males with apex rounded, whitish along the costal margin and termen, with tawny or brownish scales and hairs medially and along the hind margin, without a blotch of androconial scales near tornus.

Male genitalia ( Figs 38, 39 ). Uncus in its basal part slightly broader than in C. fumipennis , tapering, distally narrowly rounded, with relatively small basal outgrowths attached to the distal area of the tegumen; tegumen elongated, shorter than in C. fumipennis ; valva kidney-shaped, with a medium sized ring of weak sclerotisation at base of costa similar to C. fumipennis , narrowing towards the costal margin, with a small basal extension; labides a triangle bulge, larger than in C. fumipennis ; vinculum with a rather long finger-shaped dorsal process and a relatively small anterior hook; saccus broad, rounded; aedeagus relatively large, with a small row of much reduced short spines.

Female genitalia ( Fig. 50 ). Antrum broader than in C. fumipennis , short, weakly sclerotised, with a flat base. Ductus bursae shorter and broader than in C. fumipennis , with lateral areas heavier sclerotized in its proximal half. Corpus bursae large, rounded, with a small distal band of fine scobination. Ductus seminalis inserted on corpus bursae on a very small, rounded protuberance near entrance of ductus bursae. Signum a rounded patch of spicules on ventral side of corpus bursae, slightly smaller than in C. fumipennis .

Distribution. Australia (Queensland, New South Wales, Australian Capital Territory).
