Walker Gen.
rev.
Type
species: pyrochroma Walker (= spicea Guenee), Indian Subregion.
This
genus is revived to include a number of Oriental and Australasian species that
have often been associated with Perigea Guenee, Prospalta Walker
or Condica Walker.
It
consists typically of species with pale ochreous or brown ground colour to the
forewings, enlarged, pale rimmed stigmata in the forewing cell, and a darker
zone over the tornus bounded somewhat sinuously from the apex to half way along
the dorsum, this boundary often incorporating a dark patch set between the
posterior of the reniform and the postmedial. This tornal area sometimes has a
violet suffusion, a suffusion that, in some species, extends narrowly basad
along the dorsum.
In
the male abdomen there are no basal hair pencils. The eighth sternite bears a
pair of coremata supported by extensive lateral rods. The tergite is broadened,
divided into anterior and posterior sclerites in some species (e.g. malayica Snellen).
The coremata are very large in some of the species. In the genitalia the
peniculus is lobed in some species, including the type species. The valves are
distally and ventrally only weakly sclerotised, but the costa is broadly
sclerotised and the harpe and sacculus likewise, both massive. The aedeagus
vesica has the main tube at right angles to the shaft of the aedeagus, with a
distal subbasal diverticulum colinear, with the shaft; the vesica is usually
scobinate at least in part.
The
female genitalia have the ovipositor lobes and segment eight unmodified. The
ductus is unsclerotised over the basal portion but increasingly so distally in
most species. This sclerotisation continues into the base of the bursa where
there is usually a slight appendix. The bursa is pyriform and without signa,
though weakly scobinate throughout. The distal part of the ductus and the whole
bursa are usually corrugate. The membranes between the sclerites on the seventh
segment are often weakly pouched, presumably to receive the harpe of the male.
The
genus Perigeodes Hampson (type species the Indian rectivitta Moore;
monotypic) may also be related, but it lacks the facies features listed above
except for the enlarged stigmata, and has no coremata on the male eighth stemite.
The ornamentation of the valves of the male genitalia is more massive than in Bagada.
Xylostola Hampson, discussed next, may also be related.
Bagada
as
recognised here includes the following species in addition to the Bornean taxa
discussed below: B. fuscostrigata Bethune-Baker comb. n., New
Guinea; B. tricycla Guenee comb. n., N.E. Himalaya; B. magna Hampson

are a number of undescribed species in Sulawesi as well as B. cinnamomea Roepke
comb. n.
