Levu triangularis Zelazny , sp. nov.

( Fig. 177)

Description. Forewings 1.9 times longer than wide, length: male 3.5–4.2 mm (mean = 3.8, n= 3), female 3.9–4.9 mm. Colour stramineous to light brown; facial carinae orange. Forewings white, powdered; most veins brown and lined with bands of infuscation, but veins colourless in basal third of wing, in a band across middle of wing, and along apical margin; dark marks around middle of first subcostal sector, and at the forks M-Ms4 and R-Rs1. Rostrum surpassing hindcoxae; subantennal processes connected to margins of facial carinae. Forewings with Sc+R fork well before middle of wing; Ms1 branched in its basal quarter; Ms1a nearly straight; basal, triangular cell between Ms1a and Ms1b large; a triangle at base of Ms1. Male anal segment with small lateral processes; genital styles elongated, slightly truncate at the end; proximal dorsal process short, distal dorsal process elongated (no hump at its base), both well separated. Stem of aedeagus with a small spatulate dorsal projection just before apical portion; apical part broad, tapering towards the end; on the right side, a flat, dorsal lobe.

Etymology. The species name is a Latin adjective ( triangularis , -is, -e = triangular).

Diagnosis. Levu triangularis has a similar coloration compared to L. paganus (Fennah) from Ponape. It can be separated from that species by its larger size, by the forewings having a straight Ms1a vein, as well as colourless veins near the apical margin, and by the male genital styles lacking a small hump at the base of the distal dorsal process.
