Veia Walker
Type
species: homopteroides Walker,
Borneo.
Synonym: Naharra
Walker
(type species contracta Walker,
Moluccas).
Typically,
this genus has partially bipectinate male antennae and obliquely fasciated
facies as described below. The third segment of the labial palp is short. The
eighth segment of the male is typical of the group of genera discussed in the
tribal account. The male genitalia have valves somewhat similar to those of Diomea,
with a saccular harpe, but with a small, ampullate process just dorsal to it
within its curvature that is typically lacking in Diomea,
where there is more often an oblique ridge from the base of the saccular process
that runs across to the costal margin.
The
female genitalia (almana) have the ostium opening between segments seven and eight into a
single, straight, sclerotised ductus that leads into the similarly narrow neck
of the bursa that gives rise to a small appendix bursae typical of the generic
complex and beyond, after a slight kink, broadens into a pyriform corpus bursae
that contains two extensive fields of small spicules in the basal two thirds.
New Guinea
area species such as contracta are more robust, with similar oblique fasciation and
male genitalia to the type species, but in the latter the saccular process is
more robust and extends across to the costal margin. It is possible that these
should be segregated under Naharra. However, V.
pectinata Holloway
(New Caledonia), compared with and superficially similar to V.
umbrosa umbrosa Walker
(New Guinea, Bismarcks), has hightly distinctive male genitalia and is probably
not congeneric.
