Crasilogia dispar Warren : Scoble, 1999: 192 (checklist). Type material. Syntype male, British New Guinea [ Papua New Guinea]. Upp. Aroa R. , iii.[19]03. ( Meek ), BMNH ( E)#817891, NHMUK012823184 ; syntype female, same data as syntype male, NHMUK012823185 ; syntype female, same data as syntype male, BMNH ( E)#817892 ( NHM).

Diagnosis ( Figs 6, 7 , 19, 20 ). Forewings above with pattern similar to C. flavipennis , C. fulvitincta , and C. simplex , mainly dark brown, with subbasal band slightly narrower than in C. flavipennis and C. simplex , with an inwardly directed triangular subbasal notch, with median band medium sized, narrow at the hind margin, edged with whitish and rather thin bright yellow wavy lines, with a shallow medial projecting tooth outwards and a distinct inwardly directed postmedial streak near the costal margin, with a thin wavy whitish subterminal line with small medial and subapical projecting teeth. Hind wings in males shouldered at apex, whitish, lighter in colour than in other species, with a blotch of blackish androconial scales near tornus.

Male genitalia ( Figs 32, 33 ). Uncus thin, almost parallel sided; tegumen not elongated; valva somewhat kidney-shaped, with a broad ring of weak sclerotisation at base of costa, slightly narrowing towards the costal margin, with a distinct basal extension; labides thin, protruded distally, sickle-shaped; vinculum with a horn-shaped dorsal process and a large anterior hook; saccus distinctly convex medially; aedeagus relatively large, with a large patch of long cornuti.

Female genitalia ( Fig. 46 ). Antrum broad, weakly sclerotised, with a rather flat base. Ductus bursae rather short, with lateral areas heavier sclerotized in its proximal half. Corpus bursae ovate, broadly scobinate medially. Ductus seminalis inserted on corpus bursae on a small rounded protuberance near entrance of ductus bursae. Signum a small cone of spicules on ventral side of corpus bursae, surrounded by an oval membranous area.

Distribution. Papua New Guinea.
