Acolutha Warren
Type species: pictaria Moore.
Species in this genus have a very uniform facies type, consisting of
red, pink and yellow markings and suffusion on a white ground. The discal spots
and parts of the postmedial are picked out dark grey, and sometimes this grey is
more extreme. The forewing costal third is usually broadly red. Yellow suffuses
the ground colour completely or is restricted to bands associated with the
fasciae, themselves red or pinkish red. The most distinct fasciae are the
postmedials, sinuous in course, usually double. The male antennae are narrowly
bipectinate, those of the female filiform.
The male genitalia are similarly uniform through the genus, with a
simple, slender, acute uncus, a broadly scobinate subscaphium and a well
developed saccus. The valves are elongate-ovate, relatively small, with setae on
the inner lamina and a line of larger ones at the base of the sacculus. The
aedeagus vesica is scobinate, sometimes with bands of slightly larger spines.
The female genitalia have a globular bursa with coarse general spining
throughout except in a slight basal swelling or appendix. The ductus is short,
partly sclerotised.
The genus is predominantly Oriental, with the type species extending
east to New Guinea and the Bismarcks. Three out of four Bornean species are
montane.
