Diagnosis.
See the previous two species. The hindwing margin is evenly rounded. The larger
cornutus in the aedeagus vesica is very long and curved. The juxta is apically
narrower and rounded.

note. The synonymy above was published by Galsworthy (1997) in
consultation with the author.

Habitat
preference. This is the only montane Bornean species, being found from
1000m to 2600m, including records attributed to revocans
by
Holloway (1976) from 1930m upwards.
Biology.
The
larva of leucolopha in Japan was described and illustrated (as longipennis)
by Mori (1996), and has cryptic and bright forms, apparently varying according
to whether found on the trunk or leaves of the host plant during daylight. Both
forms have alternating broad black and greyish rectangles dorsally divided by a
fine yellow dorsal line, but the flanks are more brightly lined longitudinally
with yellow and white, rather than black and brown, in the brighter form; this
also has a reddish head rather than a brown one.
Host-plant
records from Japan are from Hibiscus (Malvaceae; Inoue et al. 1982)
and Tilia
(Tiliaceae;
Mori, 1996), though the latter noted a refusal of larvae to feed when offered Hibiscus.
