Oglasa Walker
Type
species: lagusalis Walker,
Borneo.
Synonyms: Chodda
Walker
(type species sordidula Walker)
syn.
n.;
Dorsippa
Walker
(type species notabilis Walker,
Borneo = lagusalis).
Chodda
has
facies and male genitalia characteristic of typical Oglasa
and
is therefore brought into synonymy. Two Australasian species included in Chodda
by
Poole (1989) are probably misplaced.
Lödl
(1998) has removed the genus Hiaspis Walker
from synonymy with Oglasa and restored it, and its Bornean type species, closteroides
Walker, as a good genus allied to Acidon
Hampson
in the Hypeninae. It also includes H. apicalis Swinhoe, placed in Radara
Walker
in Poole (1989), as discussed on p. 416.
Brevipecten
Hampson
(type species captata Butler, India) forms the basis of Brevipectenini of
Wiltshire (1990) (a nomen nudum (Kühne & Speidel, 2004; Speidel & Naumann,
2005)), but does not appear to be related to typical Oglasa,
and therefore is not available as a higher taxonomic placement for this and
related genera. Phragma lobes at the anterior of the second abdominal tergite
are strong in Oglasa and the next genus but absent in Brevipecten.
The species have distinctive forewing facies as well as complex male genitalia. Brevipecten
is
therefore best treated as separate from Oglasa,
following Sugi & Sasaki (2001) who associated it with the Bagisarinae,
rather than as a synonym as in Poole (1989).
The
forewings usually have a straw-coloured ground variously irrorated with brown of
various tints. There are dark brown triangles on the costa medially and
subbasally, with an oblique, usually lunulate reniform stigma of the same colour.
The submarginal is pale, narrow and consists of two arcs, concave distad; they
may enclose a darker zone at the margin, particularly the more anterior one of
the two. The costal triangles are shared with the next genus.
The male
abdomen shares features with the next genus such as a framed corematous type of
eighth sternite, a single but obliquely pleated valve to the genitalia, with an
aedeagus vesica that varies from globular to more elongate with diverticula.
Differences are outlined under the next genus as are differences in the female
genitalia.
