Diagnosis

Yellowish testaceous, frontal and clypeal keels whitish-yellow, the former very narrowly bordered internally with dark fuscous. (in the males the keels are less broad and less whitish). Pronotal keels whitish yellow, a dark fuscous spot on each side anteriorly. Scutellum medio-longitudinally pale with a pale brownish-yellow sinuate line on either side. Underneath pale testaceous, a fuscous spot on each mesopleuron. Tegmina hyaline, veins pale except the apical ones, which are fuscous. Lateral margin of frons subparallel, slightly narrowed basally, a little more so in the male than in the female, keels rather flattened. Antennae not reaching beyond base of clypeus, second segment nearly twice as long as the first. Tibial spur with about 27 spines. Tegmina with 8 or 9 apical cells, the 4th, 7th being pedicellate. Male pygophor pale yellowish; subrotundate viewed end-on, the lateral margins thickened and produced into a short spine near the anal tube. Anal tube with an elongate, strong, downward directed tooth from its ventral wall on each side, and about 5 tiny spines between. Aedeagus subhorizontal, elongate. Genital styles divergent, apically bifid. Female abdomen beneath more or less fuscous. Length (brach.) 2.5 (macr.) 4.5 mm; both sexes are dimorphic (Kirkaldy 1907).
