General color yellowish brown to blackish brown. Vertex from apex to tip of abdomen with a pale longitudinal stripe along median line. Vertex with disc slightly concave, lateral margins subparallel, width at base wider than length in middle line. Frons rather broad, widest part under level of lower margin of eyes, length in median line longer than width; lateral margins distinctly carinate, from apex to level of lower margin of eyes subparallel then gradually incurved to frontoclypeal suture; median carina present, weak; submedian carinae arising from basal margin of frons, slightly divergent then convergent apically, not reaching to frontoclypeal suture; each lateral area between submedian carina and lateral carina with two rows include 12 small pustules. Postclypeus with median carina distinct, lateral carinate obscure. Rostrum reaching posterior trochanters. Pronotum broad transversely, 3-carinate, median carina weak, length in median line slightly shorter than vertex. Mesonotum 3-carinate, median carina weak, length in median line shorter than vertex and pronotum combined. Forewing with length slightly longer than width, anterior and posterior margins subparallel, apical margin subtruncate, veins obscure. Hindwing absent. Legs with fore and middle femora and tibiae normal. Hind tibiae with one spine at middle. Spinal formula of hind leg 6–3–2.
