Craniophora Snellen

Type species: ligustri Denis & Schiffermuller (Europe).

Synonyms: Bisulcia Chapman (type species ligustri); Cranionycta de Lattin (type species oda de Lattin, U.S.S.R.); Hampsonia Kozhanchikov (type species jankowskii Oberthur, East U.S.S.R.; praeocc., replaced by Hampsonidia Inoue); Miracopa Draudt (type species prodigiosa Draudt, China); Meglonycta Viette syn. n. (type species mediovitta Rothschild, Madagascar).

This genus embraces species with Acronicta-like facies but having the margin of the forewing somewhat squarer, less oblique, and diagnostic features of the male genitalia: a rather domed uncus; elongated, ovate valves, usually lacking a corona, closely aligned with the tegumen, with broad, short, basal, external coremata (most unusual in the trifine groups); an aedeagus vesica with a row or comb of stout cornuti on a lateral lobe and possibly more subbasally (fasciata group), the cornuti being generally long, rod-like, large rather than needle-like, thorn-like or conical (some Acronicta). Trifine basal hair pencils are absent. The eighth sternite has a double corema/scent pencil and lateral sclerotised rods; the latter are present, though smaller, in Bornean Acronicta.

The female genitalia have a somewhat longer ductus bursae than those of the Acronicta group, with the bursa convolute and more heavily sclerotised, possibly so as to resist the stronger cornuti of the vesica. There are no signa.

The larva has long primary setae on more or less developed pinacula (Sugi, 1987). Host-plants noted are from the family Oleaceae (Sugi), as are those for the next two genera.
