species: hypenoides Walker.
typical of the genus are small, dark, with paler, fine, regular, transverse
postmedial and antemedial fasciae on the forewing and just the former on the
hindwing. The forewing postmedial is strongly angled subcostally and extends
basad parallel to the costa from the angle for a short distance before curving
round to meet it. The reniform is darkened. The hindwing margin is distally
angled at CuA2, distinguishing the species from Eublemmini with similar facies.
abdomen has the eighth segment highly modified, the sternite very broad, with
lateral rods to the apodemes and, posteriorly, a pair of large, pocketlike
structures that contain a mass of fine hairs. In the genitalia, the uncus is
divided into a broad basal half and a sharply narrower distal half. The valves
are apically acute, and semicircular beyond short processes set transverse at
the base of the costa much as in the preceding sequence of genera. The juxta is
of the inverted ‘Y’ shape, but fusion of the two convergent bands centrally
is sometimes incomplete.
female has the cleft ostium set well within the eighth segment, with small
pockets on each side of it. The ductus is moderate, narrow, but slightly swollen
asymmetrically at its distal end before a slightly helical ‘section’ leads
into a pyriform corpus bursae that becomes increasingly densely rugose towards
species and most others in Borneo (see below) have facies as described above.
Other Oriental species currently placed in the genus (Poole, 1989) have a
forewing postmedial angled more as in Anticarsia Hübner
(p. 435) and enclosing a lens-shaped area on the costa. These last have not been
dissected except for C. angulina Guenée which extends to Borneo and shows differences
in the genitalia as discussed below.
