Barasa
Walker
Type species:
acronyctoides
Walker, Borneo.
Synonym:
Ceparcha
Meyrick (type species
cymatistis
Meyrick, New Guinea).
This and the next genus were recognised formally as nolines by Holloway (1998),
but the relationship had been suggested earlier by Gardner (1943) and Sugi
(1987). They share the definitive characters of the larvae and male genitalia,
and lack ocelli. The hindwing venation is quadrifine with M3 and CuA1 stalked,
and the antennae of the male are filiform rather than bipectinate (reversed in
error in Holloway (1998)). The forewing venation has an areole, however, rarely
otherwise seen in the subfamily. The two, with the Moluccan Hypolochma
Felder and possibly
Melanographia
Hampson may form a basal branch of the nolines. The male in Barasa
sometimes has a tuft of black hairs in the costal area of the hindwing.
In the male abdomen the eighth tergite is narrow, with broad, moderately long
and closely associated apodemes. The sternite is much broader, a shallow
rhomboid. In the genitalia the uncus is strong, simple. The lateral setose lobes
of the anal tube are prominent. The tegumen is broadened exteriorly on each side
to support a mass of fine hairs. The valves are paddle-like with a simple harpe
basally. The saccular shield is present, connecting the bases of the valve
sacculi. The aedeagus is short, the vesica scobinate but without cornuti.
The female has rather square ovipositor lobes. The ductus is long, narrow, with
a slightly spined appendix bursae arising at its midpoint. The bursa itself is
elongate, pyriform, with two opposed zones of more coarsely scobinate
longitudinal corrugation in the bulbous part.
The biology of the type species and one other is described below.
The genus consists of the species described below,
vanbraeckeli
Roepke from Sulawesi, and
cymatistis
Meyrick and
griseola
Bethune-Baker from the Australasian tropics. The status of
costalis
Hampson (N.E. Himalaya) needs investigation.
