species: alboarcuata Bethune-Baker,
species of this genus has much deeper forewings than in the previous four
genera. The wings are dark brown, and the rather obscure fasciation of these is
disrupted by a massive crescent of white that runs from the base of the costa to
the tornus, edged with dark brown then a mauvish band distally. The male
antennae are very long. The hindwing has a white patch at the tornus.
eighth segment is unmodified, the tergite without apodemes. However, the
genitalia indicate a relationship with the previous two genera in the shape of
the uncus and scaphium, in the proportions of the tegumen and vinculum, and in
the paddle-like shape and size of the valves.
female has its ostium in a similar position at the posterior of the eighth
segment, but set in a slight, but robust, transverse, pouch-like structure that
completes the ring of the segment. The ductus and bursa are relatively short
compared with Asta, but much broader than in Pantura.
three Oriental species currently placed in the genus (Poole, 1989), flavicincta Hampson is definitely misplaced (see below), but the
other two are correctly placed, the male genitalia in ochrovittata
(see below) being similar to those of the type species.
