Oeonistis bistrigata Rothschild, 1912

[Oeonistis bistrigata Rothschild, 1912] (holotype: Mt. Goliath, in BMNH)

Similar species

The genus Oeonistis has a few sibling species groups of which bicolora - bistrigata is one. Confusion with identification of the two species is obvious but when you keep in mind the two most distinguishing characters it must be easy to separate the two species. Oeonistis bicolora is generally smaller than bistrigata with a much more delicate appearance. The space between the red collar line and the black head is filled with pale yellow, the ground colour of the thorax. In bistrigata the space between the red collar line and the grey - yellow head is filled with dark grey, like most of the thorax. On the forewing of bicolora the conspicuous marking is metallic shiny blue to black with a distinct angle of about 90º, while in bistrigata this marking is dull dark brown, broader and with a blunt angle of about 45º.




STATUS: Rather rare. Restricted to the Central Mountain Range.
