Caulocera
Hampson
Type
species: crassicornis Walker, Borneo.
This
is another of the diaphanous genera, species of which have a scale tuft on the
scape of the male antenna. The wing venation is similar to that of Chamaita
but R1 anastomoses with Sc in the forewing, and one species, the type, has
the veins posterior to the bifurcate system reduced to four (Fig. 5d). The
secondary sexual characters in males of the two species also differ
considerably; the type species has a fold in the basal part of the forewing
cell, but xantholopha Hampson has a
hair pencil on the dorsum of the forewing and a fold within the dorsal area of
the hindwing.

crassicornis Walker
The
male abdomen of the type species has an unusual pair of sclerotised pockets with
segments 2 and 3. The genitalia have a pair of spurs on a type of transtilla
between the valves, and the valves themselves have an elongate band of densely
packed, small, dark spines interior to the sacculus. The aedeagus vesica
contains a row of hook-like spines and a separate conical one.
The
female has an asymmetrically pyriform bursa set on a short, broad, sclerotised
ductus. The neck of the bursa is densely irrorated with numerous small spicules,
and there is a circular patch of coarser spines at the distal end. The ductus
seminalis is reflexed on one side of the otherwise immaculate distal portion.
The
genus is Sundanian, containing only the two species described below.
