Gonoglasa Hampson
Type
species: camptogramma Hampson.
The
forewing shape and fasciation is similar to that of Bornean Hepatica
species,
as is the fine, straight fascia of the hindwing. The species are larger, the
build more delicate, and the antennae are longer and narrowly bipectinate in the
male. The fasciation is paler than the ground, rather than darker. The labial
palps have the second segment long, directed forwards, but the third segment is
about one third of that length, much narrower, and directed slightly downwards.
The male
eighth segment is of the framed corematous type, the tergite with a slight
distal lacuna. The uncus is long and slender. The tegumen has a characteristic
interior with a scobinate area that extends alongside and just ventral to a
narrowly thickened margin that curves sharply round to the junction with the
tegumen. This junction is complex and may involve an intercalary sclerite. The
juxta is an inverted ‘V’ arising from the valve bases. The valves are large,
paddle-like, with a central longitudinal pleat extending from the base to about
two thirds. There is a small triangular process subbasally just ventral to the
pleat. The is short, square. Several of these features may indicate (M. Lödl, pers.
comm.)
a relationship to hypenine genera such as Acidon Hampson and Hiaspis
Walker
(Lödl, 1998), particularly the valve structure, though this is also similar to
that in Ananepa.
The aedeagus has a number of short spines apically, and the vesica has three
lobes that end in groups of spines.
The
female of the type species has the ostium associated with the eighth segment.
The ductus is very short, the bursa rather elongate, flimsy, spindle-shaped. The
seventh sternite is slightly reduced and tapered relative to the tergite.
The
genus consists of the two species below, and two more are included by Poole
(1989). G. sinuilinea Hampson
(Sri Lanka) appears to be close to G.
nigripalpis Walker,
but the placement of G. contigua Wileman (Taiwan) requires further study.
