Arguda
Moore
Type
species: decurtata Moore.
This and the next two genera, reviewed by Lajonquière (1977b), share the
following characteristics: two strong, oblique forewing fasciae that flank
the discal dot if present; in the male genitalia, a weak often totally
unsclerotised tegumen, a broad cubile, often with lateral processes and
lacking the distinct arms set in a deep pocket that characterise all
genera previously discussed; the aedeagus vesica has complex lobes with
scobinate patches.
Arguda and Radhica Moore both have a prominent ventral spur to the
aedeagus. It is more or less central in Arguda, more apical in Radhica.
Arguda has the tegumen unsclerotised whereas in Radhica it is evident as a
weak band. The dorsal lateral processes of the cubile/vinculum are bifid
rather than single, and the valves are also more complex.
Both genera have hindwings with the margins produced slightly centrally so
the wing is longer than it is deep. Arguda species are all dull red of
various shades whereas Radhica species have shades of yellow, green and
brown.
Both genera are restricted to the Oriental tropics though the genus
Pararguda Bethune-Baker, externally similar and possibly related, consists
of four species in New Guinea. Members of the complex have not been
recorded from the Philippines or Sulawesi.
