Krisna burmanica sp. nov.

Figs 47–51

Pale stramineous. Anterior margin of head, clavus at base pale brown, no fuscous spot at base of appendix.

No prominent apodemes on any of abdominal segment.

Male genitalia: Ventral pygophore process in lateral view sinuate, with small tooth at midlength and a few more before subapical expansion, spicules in basal half of expansion fewer in number than in K. megha sp. nov. (see below), apically with ridges. Apex of apophysis of style of type 1. Aedeagal shaft short and stout, preatrium short, ventral margin of aedeagal shaft in lateral view rounded, with distinct ventral concavity at mid region, in caudal view, widened near midlength, before slightly narrowing towards apex.

Measurements: Male 9.7 mm long, 2.2 mm wide across eyes, 2.7 mm wide across hind margin of pronotum.

Material examined: Holotype ď, Myanmar: Upper Burma: Seinghku Valley, Nogmune, 28°5’ N, 97°25’ E, 1500 m, 22.iv.1926, F. Kingdon Ward ( BMNH).

Remarks: K. burmanica is peculiar in not having any prominent abdominal apodemes on any of the abdominal segments. It shares the character of spiculate ventral process of male pygophore with K. megha sp. nov. (see below) but differs from it in having fewer spicules, and these are restricted to the basal half of the subapical expansion only. The aedeagus of K. burmanica has a slightly more sinuate hind margin than in K. megha where it is almost straight.
