species: punctilineata
Moore.
The male antennae are fasciculate, the wing venation of the ground plan type
except R2 branches relatively distally from R5 on the forewing. The forewing is
rather elongate, with a cryptic, mottled patterning of dark brown, green and
occasionally other colours on a pale fawn or grey ground. The hindwing is rather
round, sexually dimorphic, with the basal half tinged green with androconial
scales in males and uniform grey in females. The male lacks an anterior
retinaculum, wing coupling being of the female type.
The male abdomen in the type species has rather elongate, triangular apodemes on
the basal sternite within a slight frame; they are similar in the female but the
frame is lacking. In the genitalia, the uncus is massive, and the anal tube has
a slightly scobinate and extensive subscaphium. The tegumen is long, expanded.
The valves are elongate, somewhat careine. The aedeagus has a large, convolute
vesica; some of the diverticula are scobinate. The eighth segment is modified,
the sclerites produced basad, with short, broad apodemes on the tergite.
The female of the type species has a short, narrow ductus with a colliculum. The
bursa is large, irregularly pyriform and slightly helical, with a distal signum
consisting of a scobinate dome.
Apart from the questionable Bornean record below, the distribution is from the
Himalaya and Burma, Tibet, western China, Taiwan, Japan, Mongolia and eastern
Siberia. The host plants recorded in Japan (Sugi, 1987) are Alnus and
Betula (Betulaceae), both absent from Borneo.
