Diagnosis. This
and the next species are rather different in facies to the rest of the genus,
with the darker forewing markings a reddish grey and extending more broadly into
the white areas such that these are largely obscured except for white wedges at
the margin and a sinuous row of white dots in the postmedial area. This grey
suffusion is more extensive in fridiga, but the hindwings are a paler
grey.
Taxonomic note. The
two species are atypical of Adites, having, in the male genitalia, a more
extensive array (or arrays) of robust cornuti in the vesica, valves that are
simply divided distally, and limited rugosity around the anellus. The valves are
short in frigida but elongate in the next species and Philippines species
such as A. unilinea Wileman & South comb. n. and A.
ocellata Wileman & South comb. n., to which they may be most
closely related. These Philippines species have more typical Adites facies.
In the female genitalia of frigida, the bursa is much larger than in the bizonoides
group and is almost entirely invested with a dense array of small spicules
that extend also down the ductus bursae.
Geographical range. N.E.
Himalaya, Sundaland.
Habitat preference. This
is a rare lowland species in Borneo, the only recently taken specimen seen being
from dipterocarp forest at 300m in the Ulu Temburong of Brunei.
