Diagnosis ( Figs 12, 13 , 24, 25 ). Forewings above with pattern similar to C. gressitti , but brown to ochreous- and greyish-brown, without bright yellow or orange lines or bands, with subbasal band rather broad, with an indistinct, inwardly directed small subbasal notch, with median band broad for the genus, rather broad at the hind margin, edged with thin whitish, brownish and ochreous lines, with a medial projecting tooth outwards and a small inwardly directed postmedial streak near the costal margin, with an inconspicuous dash-like discal dot, without a whitish subterminal line. Hind wings in males with apex slightly protruded and angled, whitish outwards, with an area of brownish scales and hairs in the basal half, without a blotch of androconial scales near tornus.

Male genitalia ( Figs 36, 37 ). Uncus slightly narrower in its basal 1/3 and longer than in C. gressitti , almost parallel sided, distally narrowly rounded, with relatively small basal outgrowths attached to the distal area of the tegumen; tegumen elongated; valva rather large, shaped like a human ear, with a medium sized ring of weak sclerotisation at base of costa similar to C. gressitti , narrowing towards the costal margin, with a small basal extension; labides a very small, rounded bulge; vinculum with a finger-shaped dorsal process and a medium sized anterior hook; saccus smaller than in C. gressitti , rounded; aedeagus relatively large, with two indistinct rows of much reduced short spines.

Female genitalia ( Fig. 49 ). Antrum broad and short, weakly sclerotised, with a flat base. Ductus bursae long and narrow, longer than in C. gressitti , with lateral areas heavier sclerotized. Corpus bursae large, rounded, with a central band of fine scobination. Ductus seminalis inserted on corpus bursae on a small rounded protuberance near entrance of ductus bursae. Signum a medium sized, proximally rounded patch of spicules on ventral side of corpus bursae.

Distribution. Indonesia (West Papua), Papua New Guinea.
