Pseudeuchromia Schultze
Type species: catachroma Schultze (= maculifera Felder
& Rogenhofer).
This is probably a monotypic genus, as indicated by the synonymy and
note below, that may have affinities to the Ctimene Boisduval group of
the Australasian tropics. These genera have male genitalia typical of the
Hypochrosini (Holloway, 1984b).
In Pseudeuchromia both forewings and hindwings are rather narrow,
apically rounded, black with basal, medial and subapical yellow patches. There
is a small yellow spot on the centre of the hindwing dorsum with which the
medial spot sometimes coalesces. The male antennae are broadly bipectinate,
those of the female narrowly so. Thorax and abdomen are black, banded and marked
with yellow.
The male genitalia have typically hypochrosine vinculum and coremata,
simple valves and an asymmetric furca. The basal pocket of the furca is invested
with long setae, the right arm vestigial, the left relatively short, apically
clubbed, the interior of the club bearing a comb of robust setae. The apical
margin of the gnathus is spined. The uncus is long, with an apical expansion on
a slender neck. The aedeagus is slender with slight scobination at the apex.
The female genitalia have a weak eighth sternite combined with a
strongly sclerotised, scobinate, funnel-like ostium bursae. After a slight
constriction the ductus broadens into a pyriform, transversely thickened zone
from which the rather elongate bursa arises apically. The signum is distal,
disc-like, with a serrate margin.
