Type species: sericea Warren, N.E. Himalaya.
In facies and in the simplicity of the structure of the male genitalia,
this genus shows some resemblance to Hyposidra Guenée, but the forewings
are not falcate, sexual dimorphism is slight rather than extreme, and the
ovipositor lobes in the female genitalia are normal rather than elongate. A
fovea is present in both genera.
The male antennae are strongly bipectinate, particularly plumose in
appearance in the Bornean species, with a short apical flagellar section. The
wing margins are slightly crenulate, the facies with markings of rich brown and
black on fawn, with an irregular, white submarginal. The latter is strongest at
the centre of the forewing. The forewing medial and postmedial are strong,
adjacent but diverging at the dorsum to yield a dark triangular area.
In the male abdomen there is a setal comb on the third sternite. The
uncus is broad, triangular, apically truncated. The valves are simple, narrow,
without a definite cucullus, but having a very small spur-like process at the
centre of the ventral margin in the Bornean species. The aedeagus is short, the
vesica without strong cornuti, though in the type species there is an irregular
ring of small spines.
In the female genitalia (altapona) the ductus and bursa are equal
in length to the ovipositor lobe and segment eight, the ductus very short. The
bursa is elongate, ovate, with an irregular but typical dentate signum on a
broad base set at the distal end; in the type species the signum is narrower,
more irregular, and the bursa relatively longer.
Apart from the type species and the duplex of species in Borneo, the
genus also contains A, griseiplaga Warren from New Guinea. Though the
facies of griseiplaga is similar to that of the Oriental species,
features of the male genitalia suggest it is misplaced in Apophyga.
