Diagnosis
and taxonomic note. See costimacula above. This is a larger species with a more ochreous
brown tone to the forewing, particularly in the distal half. The male genitalia
are modified as illustrated, the valve highly so, and the juxta more typical of
the core catocalines. The aedeagus vesica and the modification of the sclerites
of the eighth segment are consistent, as is the facies, with placement in Oglasa,
however.
Geographical
range. Borneo.
Habitat
preference. The species is infrequent, but more material is from lowland
forest. There is one specimen from lower montane forest at 1000m on G. Mulu and
one from disturbed coastal forest near Seria in Brunei. Chey (1994) recorded it
in low numbers in all softwood plantations sampled during his survey.
