Selenoperas Hampson

Type species: caustiplaga Hampson.

The general facies of this species is distinctive, as described below and illustrated. Holloway (1982: 239) noted the conspecificity of Selenoperas costiplaga Hampson (Ophiderinae) and Oruza fulviplaga Warren (Acontiinae) and suggested that Selenoperas should provisionally be associated with Oruza on grounds on size and facies until a clearer understanding of the characteristics of noctuid subfamilies became available. Fibiger (2003) listed the genus within his concept of the Calpinae (see p. 5), though also indicating that much revisional work was needed on most genera so listed. The genus is perhaps better associated with the quadrifine groups as the lower clypeofrons is broadly scaleless. However, the second tergite of the abdomen is without phragma lobes (see p. 25).

The male abdomen has an eighth sternite (Fig 957) that appears to be a modification of the framed corematous type, the coremata being well developed long and narrow; there are no lateral rods. The tergite is half as broad but also has a frame-like stricture, with short, well separated apodemes anteriorly. In the
genitalia, the distal part of the valve is flimsy, tending towards corematous. The sacculus is scobinate, angular, with a distal spur. The juxta is weak, but the diaphragma is vertically corrugated and extensively scobinate. The uncus is very slender, with a crest of hairs near the apex.

The female genitalia are somewhat as in the Saroba group of genera, with the ostium associated with a scobinate area extending from the anterior of the eighth segment. The ductus is sclerotised, moderate, with a slight twist in the corpus bursae at the point of junction of the ductus. The corpus bursae is ovate, without ornamentation. The genus is monobasic.
