species: tumida Hampson, Borneo.
The last genus of the Carea
facies type has the forewings
distinctly broadened distally, the costa becoming strongly concave in some
species, shaping the forewing like an axe-head. Moths with typical facies can
have a bell-shape when at rest, particularly males of D. ducalis Bryk
comb. n., and are sexually dimorphic, females tending to have modification
of the forewing shape less extreme.
The male abdomen is typically careine. In the genitalia the uncus is tapering,
apically falcate. The subscaphium is prominent, elongate. The tegumen is
strongly expanded ventrally on each side. The valves are broad, rather
rectangular, with the central lamina rather flimsy and balloon-like; the costal
process is overlapped by a basally directed lobe on the margin (seen also in Didigua),
and the ventral margin of the valve usually has a central lobe. The aedeagus
vesica is globular, with variably one to three strong, narrow cornuti.
The female (type species) has a narrow, convolute ductus, expanding into a
thickened zone, also convolute, at the base of the corpus bursae opposite the
origin of a narrow appendix bursae. The bursa is expanded distal to this,
slightly corrugate, the signum a narrow, longitudinal band of sclerotisation
with a central ‘nipple’.
All described species are Sundanian, with tumida extending to the
Warren comb. n. from the Nicobars appears to be closely related to
tumida). There are possibly undescribed species in Sulawesi and Seram.
