Striogyia Gen. n.
Type species: snelleni sp. n.
The forewing venation is typical of the Darna group, more extreme
in the , but the
male antennae are filiform as in Trichogyia, Limacosilla and Ceratonema.
The forewing facies includes a pale, very slightly sinuous, oblique
postmedial running from the apex to the centre of the dorsum. Basal to this
fascia the wing is longitudinally striate in pale and dull brown. Distally it is
more uniform dark brown and there is a fine, pale submarginal fascia curved
parallel to the margin.
In the male genitalia the uncus is rectangular, the gnathus long,
slender, downcurved, running over a distinctive corrugated 'saddle' formed
from the transtillae. The valves are somewhat divided into saccular and setose
distal portions as in Trichogyia, and there is a clavus-like structure on
the interior of the sacculus. The eighth sternite is slender, sclerotised,
biarcuate, with the concavities directed posteriorly.
In the female genitalia the ovipositor lobes are rather elongate,
laterally compressed; the ostium has a bilobed transverse flap; the apophyses of
the eighth segment are short; the ductus is spiralled; the bursa contains a
single scobinate signum as in Trichogyia.
The genus contains two species: snelleni and the Javan foliola
