Long flexuous setae present on head, gaster and abdomen: on head especially in frons, on gaster more on the posterior margins of tergites and sternites.

Mandibles relatively short and with four denticles, capable of closing tightly against the clypeus. Denticles increasing continuously in size from most proximate to most distal denticle. Surface of mandibles smooth, covered with short pubescent hairs. Antennae are relatively long in comparison with head width (SI 0.68-0.78; mean 0.72) and covered in short, pubescent hair.
