species: polymesata Walker.
facies and wing shape are similar to those in Goniophila,
but differ as described in the diagnosis of the only species (see below).
species has some similarity in facies to Goniophila as
described below. The pattern of the hindwing is more extensive than in Goniophila.
The male antennae are finely ciliate. The labial palps are relatively small,
upcurved, rather club-like, with a very short third segment. The legs are not
conspicuously tufted in the male. The phragma lobes of the second abdominal
tergite are shallow.
male abdomen the eighth segment is reduced to the anterior margin, consisting of
narrower bands of sclerotisation, that of the sternite three times the width of
the tergite, including what are probably lateral rods. The seventh sternite has
a slender central apodeme. In the genitalia, the uncus is rather angled, with an
apical spur, and is opposed by a scaphium. The valves are simple, somewhat
rhomboidal, and the sacculus terminates with a sharp angle that supports a
sinuous spine extending across the centre of the valve. The juxta is circular.
The aedeagus vesica is small, slightly scobinate.
female, the ostium is situated between the seventh and eighth segments and is
flanked by a pair of densely scobinate patches on the intersegmental membrane.
The ductus is irregularly sclerotised and joins the bursa at a slight kink. The
bursa is slightly rhomboidal, finely crinkly and scobinate, with an oblique
pleat at its widest point.
