Monosyntaxis trimaculata Hampson

Monotaxis trimaculata Hampson, 1900, Cat. Lepid. Phalaenae Br. Mus., 2:182.

Diagnosis

The females of this and Monosyntaxis holmanhunti Hampson are readily distinguished by the blackish hindwing border of the latter, though both have blue-black forewings broken by a row of three elliptical pale yellow patches. The males are entirely blue-black except for a dull reddish or orange patch at the base of the forewing. This patch is more conspicuous, dull orange in trimaculata, which is also larger overall, but dissection of the genitalia may be necessary in ambiguous cases. In trimaculata the saccular part of the valve is larger and more robust relative to the dorsal part. The saccus is much larger, and the aedeagus is broader.

Geographic range

Borneo.

Habitat preference

Lower montane.
