Clethrophora Hampson

Type species: distincta Leech, Japan, Korea.

facies and forewing shape is distinctive as described for the Bornean species below; there is some sexual dimorphism. The bifalcate forewing shape is reminiscent of that of quadrifine noctuid genera such as Anomis Hübner and allies.

In the male abdomen, the eighth segment is n
arrow, with strong apodemes, and there is a pair of short coremata laterally between it and the seventh segment. The genitalia have the valves centrally slightly constricted, distally paddle-like, with the sacculus closely associated with the vinculum, expanded slightly to bear numerous hair-like setae on conspicuous bases; in the Bornean species this area is more extensive and bears untidy, carpet-like scaling. The aedeagus and vesica are narrow, the latter without cornuti.

The female has the ovipositor lobes highly setose and rather ‘stomatal’ in form. The ductus is very long and slender, leading to a large, heart-shaped corpus bursae with the distal half densely spined and the basal half with numerous more lightly spined circular patches.

The type species feeds on Quercus (Fagaceae) in Japan (Sugi, 1987).

The genus ranges from the Himalaya to Japan and Sundaland. C. virida Heylaerts stat. rev. (Java) is not, as stated in Poole (1989), a synonym of distincta, but appears to be closer to the Sumatran C. gonophora Prout.
