Diagnosis

Coloration. Light brown. Clypeus light brown, paler medially. Frons uniformly brown. Vertex and pronotum pale medially. Mesonotum light brown with testaceous granules; median and lateral carinae flanked by testaceous lines. Tegmen as in type species. Legs pale brown. Morphology. Head, thorax and tegmina similar to type species. Front margin of vertex undulate. Apex of hind tibia with eight spines with one set at different level to other seven in sole specimen known. Male genitalia. Pygofer with minute process on posterodorsal corner. Paramere narrowed from basal half to apex which curves dorsally and is continuous with outwardly curved elongate process. The aedeagus bears two pairs of apical processes originating from the apex in a similar way to those of B. cinerascens but the lateral pair curve outwards and are longer than the apical pair which cross over near the apex and do not extend beyond the level of the dorsal edge of the aedeagus as they do in the other three species (Fletcher 1988).
