Frontal sulcus deep and reaching hind point of eye from end of frontal rostral lobes. Anterior frontal fovea round, posterior frontal fovea elongate. Eye small and prominent, onethird length of temple. Thorax: Prosternum as long as wide, widest at one-third length. Elytra rectangular ( Fig. 3f ). Hind wings well-developed. Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse patches of microtrichia reaching middle. Aedeagus: Median lobe longer than parameres, with faucet-shaped apical lobe ( Fig. 4f ). Phallobase of median lobe asymmetrical and triangular ( Fig. 4f ).
