species: rufostrigata Bethune-Baker,
The forewings are relatively narrow for a catocaline, as in Avitta
and relations discussed on p. 189. The facies is typically a deep, slightly
variegated black, but with variants as discussed below under the only species.
The hindwings are white with a broad black border to the margins. The male
antennae are about four-fifths the length of the forewing, filiform.
The male abdomen has the sternite of the eighth segment with shallow apodemes,
but is otherwise unmodified, apart from dark elliptical patches on each side of
the tergite. In the genitalia, the uncus has the apex with dorsal and ventral
spurs with a narrow cleft between them. The valves show weak bilateral asymmetry
in the spurred flange that runs transversely from the distal end of the sacculus
to the costal margin. The juxta is a typical X-shape, there is a well developed
saccus, and the aedeagus vesica is highly convolute, scobinate in places.
The female genitalia have the ostium at the posterior edge of the distinctly
reduced seventh sternite, but this is not extended into an antevaginal plate.
The ovipositor lobes are rather square, without a more sclerotised longitudinal
strip. The ductus is separated into two sclerotised sections separated by a
short unsclerotised discontinuity. The distal section is shorter and narrower
than the basal one. The somewhat rectangular corpus bursae is much larger than
is set asymmetrically on the ductus, with the ductus seminalis arising from near
the basal corner more distinct from the junction with the ductus. The interior
surface of the bursa is slightly and evenly rugose.
Relationship to Nagia is unclear from the male genitalia, with similarities in the
transverse ornamentation of the valve and in the shape of the juxta (but not its
robustness), but the valve lacks the corema of Nagia;
the uncus is apically simple in Nagia.
