Tinoliodes
Wileman
Type species: benguetana Wileman (Luzon).
Synonym: Niasana Roepke (type species dehanna Pagenstecher)
syn. n.
This genus contains two species, one Sundanian, described below, and the
type species from Luzon. It brings two genus group names together. The species
share the following features: extreme (for Arctiinae) distal branching of veins
Rs and M1 in the hindwing; a slight subapical concavity in the hindwing costal
margin; a forewing pattern of pale patches on greyish brown, (a basal one and
postmedial pairs, fused in dehanna, at the costa and dorsum, the exterior
element of each pair being darker than the interior one); in the male genitalia
the uncus is flanked by a pair of slender socii; the valves are sinuous, with a
central portion more membranous than the rest.
Females of benguetana are not available for study. In dehanna the
ovipositor lobes are densely setose; there is a pair of balloon-like glands
dorsally between the ovipositor lobes and the eighth segment; there is a small
appendix to the ductus bursae; the ductus seminalis arises from the centre of
the bursa which is almost completely invested with a dense coating of small,
dark spicules.
