Diagnosis. Males. Head: rounded-trapezoidal, tempora slightly rounded behind ocular canthus, vertexal foveae obvious, frontal sulcus broad, shallow, between foveae; antennal acetabula remote, antennomere 2 rounded, wider than first, antennomeres 3–8 unmodified, antennomeres 9–11 forming loose club; labrum of normal form for tribe, bearing pair of sensory pegs, mandibles broadly sickle-shaped, maxillae and labium typical for subfamily, labial palpi minute, 2-segmented, maxillary palpi unmodified, palpomere 1 minute and obliquely joined to palpomere 2, palpomere 2 pedunculate, narrower in basal one-third, slightly expanded and rounded distally, palpomere 3 subtriangular, palpomere 4 widest, unmodified, bearing apical palpal cone; gula simple, slightly rounded anteriorly, paired gular fovea present; eyes well-developed, comprised of about 20 facets each. Thorax: pronotum rounded trapezoidal, disc evenly convex, antebasal transverse sulcus bisected by short, basal carina, margin delimited by lateral antebasal fovea, longitudinal median sulcus absent, lateral antebasal fovea present, prosternum convex, median procoxal fovea present, lateral procoxal foveae present; mesoventrite bearing paired lateral mesoventral and mesocoxal fovea, mesocoxae contiguous; lateral metaventral foveae present, metacoxae conjunct; legs variously modified; elytra with sutural fovea and striae, two basal discal foveae present, subhumeral foveae present, lateroapical cleft present, wings present or absent. Abdomen: tergite II with small basolateral foveae, mediobasal foveae delimiting median sulcus; tergite III with small basolateral foveae, mediobasal foveae delimiting median impression; tergite IV with small basolateral foveae; ventrite II with large basolateral foveae and setose lateral sulci; ventrites III–IV with small basolateral foveae, variously modified; ventrite VII ovate, hinged penial plate. Genitalia: strongly asymmetrical; composed of basal bulb with ventral strut; accessory processes often extensively modified.

Females: similar to males except eyes usually smaller, composed of fewer facets, and secondary sexual modifications of the legs absent).
