Head (Figs 1–3) longer than (HL1) or about as long (HL2) as the pronotum, slightly narrower than pronotum, HW/PW: 0.83–0.86. Head longer than wide, HL1/HW: 1.37–1.50, HL2/HW: 1.10–1.13.

Pronotum (Figs 1, 2, 5) slightly wider than long, PW/PL: 1.07–1.18.

Elytra (Fig. 1) elongate, EL/EW: 1.46–1.64 in males, 1.44–1.54 in females. The length of the basal apophysis of the metanotum (alacrista) (Fig. 4) is approximately 9–14% of elytral length.
