Type species: aeruginaria Denis & Schiffermüller
Synonym Leucoglyphica Warren (type species pallescens
Hampson, S. India), not checked by dissection.
Species in this genus have a variety of facies types as in Maxates
and Chlorissa, with definitive features being found in the male
abdomen. The male antennae are bipectinate, of the adpressed, untidy type,
distinguishing the genus from members of the Hemithea group of genera.
In the male abdomen the eighth sternite is apically notched
or bifid, the bifurcations usually sclerotised, sometimes rugose. The valve is
usually simple, with coremata, and distinguished by an oblique groove or
declivity running from the
transtilla to the centre of the ventral margin. This groove is modified in
various ways. The third sternite bears setae, usually in a sparse circular
central patch (Fig 384).
The female genitalia
have the modified type of ovipositor lobes, a narrow, often sclerotised and
corrugate ductus, and a more or less spherical bursa with a bicornute signum or
modification of it.
The larva is typical of
the Hemitheiti, slender, green, twig-like, with a biconical head capsule: a
Japanese species is illustrated by Sugi (1987). Japanese species, including the
type species, have been recorded as feeding from the families Aceraceae,
Betulaceae, Caprifoliaceae, Cercidiphyllaceae, Ericaceae, Fagaceae, Pinaceae,
Rosaceae, Saxifragaceae and Stypheleaceae (Nakijima & Sato, 1979).
The genus is most
diverse in the Oriental mainland tropics and subtropics but extends into the
archipelago to Sulawesi and also into temperate latitudes. There are five
species in Borneo.
