Type species: translucida Moore = baliata Felder &
This genus has been exhaustively revised by Fletcher (1974). It is
extremely diverse in the African tropics, with over 200 species. Only ten in two
species groups occur in the Oriental tropics, and half these are known from
Fletcher defined the genus on the basis of the wing pattern which has a
basal hyaline zone and a distinct fully scaled border, and a fulcrum-like
supporting process attached to the ventral surface of the aedeagus. Similar
facies occurs in Peratophyga xanthyala Hampson and allies, but these lack
the aedeagus feature and have the characteristic fovea and venation of other Peratophyga.
The antennae of both sexes are bipectinate. The male genitalia have a
strong gnathus and well developed coremata. The aedeagus vesica usually bears a
large distal cornutus. The female genitalia have a short ductus, a scobinate,
often fluted, parallel-sided basal zone to the bursa, with a spinose, mushroom-shaped signum centrally to distally in the distal bulbous part. The sterigma is
sometimes modifed with lobes or acute processes.
The larva of the type species has been described and has diagnostic
features in common with Peratophyga (Singh, 1953, 1957).
Host-plant records are few, mostly from Leguminosae such as Acacia,
Cassia, Crotalaria and Dichrostachys, but Fletcher noted one
record from Ochna (Ochnaceae), and Z. eogenaria has been recorded
as feeding on Theobroma (Sterculiaceae).
