Type species: omega Hubner, junior objective synonym of verruca
Fabricius, a New World species.
The generic type species shares with A. signata Fabricius,
recorded from Borneo below, the following characters of the male abdomen and
genitalia: there are lateral zones of scales on tergite 7; there is a
distinctive plate of fused scales associated with the eighth tergite; the eighth
sternite has coremata associated with two narrow, dark bands of sclerotisation;
the saccus is large, broad; the aedeagus vesica is shorter than the aedeagus
with a single, terminal, blade-like cornutus.
The lateral zones of scales on tergite 7 support the association by
Ichinose (1973) of Argyrogramma with Ctenoplusia/Acanthoplusia as
they are found in the tarassota Hampson/sigillata Dufay group
discussed below, though not in C. albostriata Bremer & Grey.
