Diagnosis. Body depressed. Clypeus often with spines or teeth on anterior margin; Hypostomal sutures confluent in posterior portion. Gular sutures separated from fused posterior tentorial pits, parallel in anterior half, and then sharply divergent posteriorly. Anterior margin of labrum truncate or slightly emarginate; maxillary palpus with article 3 equal to 2 and longer than 4, article 4 subulate. Pronotum with anterior lateral angles produced; pronotal lateral and posterior marginal bead present. Scutellar impression bi-reniform, heart-shaped, or crest-shaped (as in Anotylus ). Elytral epipleural ridge present; elytral suture overlapping (or not in some species). Tarsal formula 3-3- 3; tarsomeres 1 and 2 nearly equal in length; tarsomere 3 longer than 1 and 2 together. Abdominal segments II to VI each with two pairs of laterosternites; tergites without basolateral ridges. Aedeagal median lobe with a pair of projections derived from median lobe capsule (different from the apico-medial hook in Oxytelus , cf. Makranczy 2006; Lü & Zhou 2012).
