Teulisna plagiata Walker


Diagnosis.
This 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).

Geographical range. Borneo.

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 latter.
