(Figs. 14–19)

Body evenly rounded, convex and pubescent. Head moderately broad, eyes present. Antennae 11 segmented the two basal antennomeres forming a scape and 9–11 a loosely jointed club. Mentum sides bulging slightly before the anterior margin, the pair of longest setae situated medially, not at the anterior corners. Submentum with five setae. Pronotum broader than long, widest at hind angles, evenly curved anteriorly and without side margins; hind angles distinct more or less rightangled. Elytra widest at humeri, with pubescent epipleura, evenly rounded and tapering posteriorly to cover the abdomen. Scutellum triangular. Wing membrane without a clear medial constriction, fringed by setae. Procoxae adjacent without a carina. Mesoventral collar narrowing sharply before the humeri and with a narrow median ridge between the anterior and posterior margins. Mesocoxae separated by a broad keel extending anteriorly to the collar. Anterior margin of metaventrum with broad raised border around the mesocoxae and clearly marked lines posterior to the meso/metaventral suture, curved posteriorly from the mesocoxal insertions and turning sharply rearwards before the lateral margins. Hind margin of the pygidium serrate with clearly marked teeth. Metacoxae almost contiguous, separated by a sharply pointed bifurcate extension of the metaventrum. Metacoxae with small plates concave before lateral margins. Male aedeagus with parameres. Female spermatheca +/- ovoid with transverse patterning.
