Schistorhynx Hampson

Type species: argentistriga Hampson, India.

The forewing facies is distinctive, with its broadly and continuously lineated dorsum and distal margin, and with the white streaks in the semi-circular costal area defined by this. The male antennae are fasciculate, and the foretibia has a fringe of scales along its length. The labial palps are long, directed forwards, the straight third segment much longer than the slightly upcurved second and having a dorsal crest of scales.

The male abdomen has the eighth sternite with a rather elongated framed corematous sternite with slight lateral rods and a single corema; the tergal sclerotisation is narrow anteriorly but expands as a splayed pair of narrow bands posteriorly that support the distal tumescence mentioned on p. 16. The genitalia have very narrow valves with a slight lobe at the distal end of the sacculus. The saccus is tapered, acute. The juxta is a simple plate. The aedeagus vesica terminates in an oblique brush of slender spines.

In the female genitalia (
argentistriga) the ovipositor lobes are very short. The ostium is at the anterior of the eighth segment, flimsy, leading into a narrow, but moderate ductus. The corpus bursae is set asymmetrically on this, an elongate and narrow pyriform with fine scobination in the distal bulb.

The genus includes the two species below and unistriga Roepke (Sulawesi, S. Moluccas).
