Diagnosis. Length 8.5–12.5 mm (males), 8.5–12.0 mm (females); width 4.0– 6.5 mm (males), 4.5–6.5 mm (females). Antennae with 9–10 antennomeres, male and female antennal club distinctly shorter than the pedicel. Pronotum with small, dense punctures ( Figs. 1–2 View Figures 1–5 ). Males and females not brachypterous and fully extended wing longer than elytra.

Distribution. Chile: Coquimbo, ValparaÍso, Metropolitana de Santiago, O’Higgins, Maule, Ñuble, BiobÍo ( Fig. 17 View Figure 17 ).

Comments. Gutiérrez (1951) stated that he only observed two specimens out of 220 that had 10 antennomeres and characterized them as aberrant. We observed a far higher percentage of specimens we examined with 10 antennomeres, so clearly the number of antennomeres in this species is variable and an unreliable diagnostic character.
