Etymology

The specific epithet is derived from the New Latin adjective ‘ bispinosus , - a, - um ’ (= ‘two-spined’), referring to the two spine-like apical aedeagal processes.

Type material

Holotype

MALAYSIA • ♂; Sabah, Tawai ; 8 Apr. 1977; M.E. Bacchus leg.; BMNH.

Paratypes

MALAYSIA – Sabah • 1 ♂, 6 ♀♀; same data as for holotype; BMNH . – Sarawak • 2 ♂♂, 11 ♀♀; Gunung Mulu National Park, West Melinau Gorge ; 3 Apr. 1978; J.D. Holloway leg.; BMNH .

Description

MEASUREMENTS (mm). Body length. ♂: 4.6–4.7; ♀: 4.7–4.8.

COLOURATION. Colour and external characters as in generic diagnosis with forewings with whitish hyaline patches.

MALE GENITALIA. Pygofer side longer than basal width in lateral view, without processes. Subgenital plates very long, approximately 4 times as long as basal width, bearing 14 long macrosetae. Style with apophysis very long and sinuate. Connective stem long approximately twice as long as arms, arms divergent; a lightly sclerotized area on each side. Aedeagal shaft moderately long approximately equal in length to connective, in lateral view evenly curved dorsally and similar in width throughout length, slightly tapered to apex in dorsal view, with a pair of spine-like apical processes, gonopore apical; basal apodeme very short; preatrium absent.

Distribution

Malaysia (Sabah, Sarawak).

Remarks

This new species can be distinguished by the spine-like apical processes of the aedeagus, long connective and long apophysis of the style.
