Name

Panesthia birmanica Brunner von Wattenwyl, 1893 – Wikispecies link – Pensoft Profile

• Panesthia birmanica Brunner, 1893: 54; Roth 1979: 67; Feng and Woo 1990: 213.

Remarks

This species is distinguished from other species by its small body length, ranging from 22.5 mm to 28 mm; and also by pronotum virtually flattened, anterior margin slightly thickened, entire or weakly indented in male, entire and not thickened in female (Fig. 68); as well as the caudal angles of T7 acute and posteriorly directed (Fig. 71); hind margin of supra-anal fig smooth or slightly crenulate, with the lateral teeth acute in apexes (Fig. 73); anterior ventral margin of front femur with 0–3 spines and with small distal spine, and posterior ventral margin with a large distal spine. The caudal angles of T6 sometimes with an acute spine separately may confuse this species with species in the genus Miopanesthia, but can be distinguished by the shorter hind metatarsus, as stated in the genus remarks. Roth (1979) determined that the tegmina and wings were polymorphic in this species since the specimens he examined had both the macropterous and brachypterous forms. The tegmina and wings are fully developed (Figs 19, 69–70) or mutilated on all material of this species we examined.
