Nola bifascialis

Diagnosis and taxonomic note.
This and the next three species are all small with transverse greenish brown banding of various shades and thus may be related to similar species such as
N. mesotherma Hampson (Sri Lanka) and N. erythrostigmata. This species is externally inseparable from mesotherma, sharing the pale brownish green transverse banding of the forewing that is somewhat darker in the medial zone between the postmedial and antemedial, though this is broken by a paler band just basal of centre that is more obvious towards the costa. This pattern is slightly more variegated in bifascialis. The male genitalia have the valves deeply cleft, each slender arm expanding towards the apex. The harpe in both species is relatively distal, a slender, distally directed spine in mesotherma and a more broadly based, slightly basally directed spine in bifascialis. The aedeagus of mesotherma has a coxcomb-like cornutus on the vesica, lacking in bifascialis. The apodemes of the eighth abdominal segment are also similar. The female has a broad, sclerotised, tubular ductus and a globular corpus bursae, lacking signa, but having a slight distal appendix. The specimen from Sandakan listed under erythrostigmata by Hampson (1900) is in fact bifascialis.

Geographical range. Borneo.

Habitat preference. All material is probably from the lowlands, three recently collected specimens from disturbed areas with secondary forest: Anduki; Ulu Temburong; Danum Valley.
