Diagnosis.
This and the
next species are very similar, with narrow darkish grey-brown forewings with a
pale yellow costal streak. Both have a postmedial band, but this is broken at
the streak in plumbeomicans and
continues through it in flavicosta Moore.
The hindwings are dark as the forewings in flavicosta
but broadly paler in the dorsal half in males and entirely pale cream in
females of plumbeomicans. The
genitalia are also strikingly different as illustrated, particularly the broad
aedeagus and bursa in flavicosta versus the narrow ones of plumbeomicans.
Taxonomic
note. The
genitalia of the holotype female of destriata
match those of a female of plumbeomicans
(slide 5400) from Burma. The structure of the male and female genitalia,
particularly the deep, triangular, apically divided valves, rather flimsy
tegumen and uncus and small aedeagus vesica of the former and the very small
ductus and bursa of the latter, is shared with the type species of Zadadra.
Geographical
range. N.E.
Himalaya, Burma, Borneo (destriata).
Habitat
preference. The
only specimen seen, the holotype of destriata,
is from Pulo Laut.
