Head long, length from cervical constriction to clypeus 1.3× as maximal width between genae, straight divergent from cervical constriction to eyes, genae slightly surpassing eyes and with shallow impression, anterior margin of clypeus straight, symmetrical, frons without medial keel or impression, surface with dense but not confluent punctures, each puncture with a light decumbent and acute seta. Pronotum long, narrow, 1.4× as long as wide, widest at anterior corners, sides straight convergent to base, posterior corners rectangular, anterior corners not protruding, disc with a feeble longitudinal impression, without keel, punctures and setation as on head. Elytra elongate-oval, widest in middle, 2.3× as long as wide, humeral corners distinctly protruding forward, punctures in elytral rows large and dense as on pronotum, intervals flat but becoming convex laterally and apically, not keel-like, acute decumbent setation longer than on head and pronotum, lateral margin of elytra visible from dorsal near humeral angles and apically; epipleura with a row of large punctures along entire length. Ventrites with finer, sparser punctures than on pronotum, punctures with very short decumbent setation.
