Pronotum flat, narrower than head; tibial spurs 2-2-2; tarsi trimerous, with second tarsomere distinctly projected ventroapically, extension longer than dorsal length of second tarsomere (Fig. 4D). Forewing with scale overlapping base of hind wing scale, slightly larger than hind wing scale (Fig. 4C), scale without numerous setae over surface, with long setae along humeral margin (Fig. 4C) (other stylotermitids have numerous and relatively long setae over the entire scale surface).

Etymology.
