Elytral micropunctures fine, on posterior half obsolete. Elytral apices emarginate, with acute parasutural spine; in males sutural angle broadly rounded, comprising the three inner striae; in females the emargination a little broader and the sutural angle produced into a short straight spine. Mesoventral process laminar, with large, curved, but not acute, anterior tooth, behind the margin obliquely lowered. Metaventral process narrow, with small median depression; posterolateral angles produced into triangular laminae, posterior angle not raised. First ventrite carinate medially only between metacoxae, with deep, moderately large lateral depressions. Fifth ventrite with shallow apical notch in females, in males raised into a disc around a narrow, very deep notch (Fig. 21B). Lateral margins of abdominal ventrites smooth. Meso- and metafemora with pubescence on basal three-fifths and three-quarters respectively. Male protarsi with the two basal tarsomeres thickened, bearing adhesive soles; first about twice as long as second, fourth slender, longer than 3 basal segments taken together. All claws long, slender, very weakly curved.
