species: leporina Linnaeus (Palaearctic).
genus is here applied in a broad sense to cover all taxa with grey forewings
that have bark-like markings, usually with strong basal and subtornal black
streaks (often joining in a continuous line), combined with a robust harpe
(often bifid or trifid) on the sacculus of the male genitalia. The
genera Craniophora Snellen, Thalatha Walker and Thalathoides Gen.
n. share the facies features but have diagnostic features in the male
(1979) and Inoue et al. (1982) divided Japanese taxa in the Acronicta group
into several genera but diagnostic features were not listed in English; the
larvae in the group show great variety in the form, colour and development of
their secondary setae and so could provide a basis for classification. Sugi
(1987) referred to these and also to genitalic features as providing the basis
for his division.
broader concept of Acronicta (e.g. following Leraut (1980)) is used here
in the absence of a clear-cut revisional treatment of the complex that lists
diagnostic (apomorphic) features for the genera recognised. The classification
in Inoue et al. (1982) recognised the following genera (mostly treated as
subgenera of Acronicta by Leraut):
Arctomyscis Hubner, Apatele Hubner, Acronycta Treitschke).
(type species strigosa Denis & Schiffermuller).
Sugi (type species omorii Matsumura).
Butler (type species soluta Walker = pruinosa Guenee).
(type species psi Linnaeus)
Semaphora Guenee, Cuspidia Chapman)
(type species alni Linnaeus).
(type species carbonaria Graeser).
Kozhanchikov (type species megacephala Denis &
(type species rumicis Linnaeus).
Pharetra Hubner, Chamaepora Warren).
broader concept for Acronicta was also used by Franclemont & Todd in
Hodges et al (1983). They included several more generic synonyms: Cometa
Sodoffsky, Sematophora Agassiz, Microcoelia Guenee, Megacronycta
Grote, Lepitoreuma Grote, Eulonche Grote, Mastiphane Grote,
Pseudepunda Butler, Tricholonche Grote, Philorgyia Grote.
