Limantricodes
Gen. n.
Type species: pulverulenta Hering comb. n. (Macroplectra).
The moths are small, rather lymantriid-like, with male antennae
bipectinate almost to the apex and forewings that are deep, approximately
triangular. Forewing vein R1 is slightly sinuous within a broad space
between Sc and the R stem in the cell, though this feature is not as extreme as
in Narosa and allies. R5 arises from the cell independently
from the rest of the R veins as in Darna, Trichogyia and allies, and
there is some curvature to the cubital veins.
The colouration is pale pinkish brown with diffuse, transverse, darker
bands on the forewing.
In the male genitalia the uncus is broad, rounded or bilobed apically.
The diagnostic feature is a triangular process set in the centre of the interior
of the valve subapically. This may conceivably be homologous with the costal
process of the Darna group but, if so, is much displaced distally. The
type species has a setose lobe on the valve costa and a calcar-like structure
between the valves; both features are absent in Bornean species.
In the female genitalia (pulverulenta) the ductus is short,
unspiralled, the bursa weak with a signum at one third, a circular zone of
sclerotisation with a pair of slight scobinate peaks on the lateral edges.
The genus contains two species, pulverulenta from the N.E.
Himalaya, and a new species, parva, known from a single Bornean male.
Specimens of pulverulenta are labelled as having been reared from apple (Malus,
Rosaceae).
