Punctation: vertex of head with several large umbilicate punctures on each side, pronotum with a few punctures, elytra finely punctate, in outer part of disc more densely so. Microsculpture: reticulate, distinct on head and weak to obsolete on pronotum and elytra. Antennae as illustrated (Fig. 10). Pronotum 1.3 times as wide as long. MALE: tergite 8 with two small lateral teeth and large median lobe (Fig. 73); sternite 8 broadly rounded apically (Fig. 74). Median lobe of aedeagus with approximately triangular tubus projecting ventrally, its venter strongly sinuate, apex narrow and acute (Fig. 71), dorsal projection of internal sac narrowly elongate and arcuate (Fig. 71). Paramere as illustrated (Fig. 72). FEMALE. Tergite 8 similar to that of male and with apical lobe (Fig. 76); sternite 8 broadly rounded and slightly pointed medially (Fig. 77); spermatheca as illustrated (Fig. 75). <b>Bionomics.
