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.
