Pantura Moore
Gen. rev.
Type
species: ophiusalis Walker,
Sri Lanka.
Synonym: Imleanga
Lucas
(type species fluviatilis Lucas,
Queensland, = lunifera
Druce,
a subspecies of ophiusalis).
The
facies characters of both species in this genus are described below. The male
antennae resemble those of Asta, and the tibiae of all the legs are
slightly tufted.
In the
male abdomen, the eighth sternite is distally bidentate as in Avitta,
but has a laterally oval lacuna anteriorly that supports a brush of setal
bristles from its anterior half. The tergite is partially divided by an anterior
semicircular cleft separating broad, short apodemes, and by a posterior V-shaped
zone of weaker sclerotisation. In the genitalia, the uncus is hooked and there
is a large scaphium as in Asta and the next genus. The tegumen is very much longer than the
vinculum, their junction on each side being marked by a distinct notch in
otherwise continuous sclerotisation (see also the next genus). The valves are
large, paddle-like, very narrow towards the base. The bases fuse in a complex
manner ventral to the juxta which is broad and an inverted ‘V’ shape. The
aedeagus has lateral flanges where it joins the anellus, and the vesica is very
small. The genitalia of the next genus are very similar apart from the aedeagus
characters.
In the
female, the ostium opens between the eighth and seventh segments, the latter
with the sternite slightly smaller than the tergite. The ostium narrows into a
flimsy and slender ductus that imperceptibly broadens into a very small and
slightly corrugate, pyriform corpus bursae. The ductus seminalis is relatively
basal on this structure.
The only
host record is from the Lauraceae (see below).
