Teulisna plagiata Walker
Walker, 1862, J. Linn. Soc. (Zool.), 6:109.
is one of four Bornean species with a broad black bar across the centre of the
forewing but does not reach the costa. It has the strongest irregular black
submarginal markings just distal to the black bar, and the male hindwing has a
distinct grey border to a straw ground colour that is only seen in the next of
the other three species. The male genitalia lack a costal process to the valves
and have a robust, asymmetrically clavate saccular process. The aedeagus has a
digitate process apically, but the vesica is unadorned.
Taxonomic note. Taxa
from Java and Bali such as atratella Walker and bertha Butler are
distinct, resembling semibrunnea Heylaerts (Java) in genitalic features,
as does the next species. These taxa have been synonymised with plagiata in
the past, e.g. by Hampson (1900).
Habitat preference. The
species was found to be common at 1000m on G. Mulu and 900m on G. Api in lower
montane forest. Singletons were taken at 500m on the former and 250m on the
