Postclypeus with six bristles at anterior margin; labrum with numerous bristles. Pronotum with few short hairs on both margins; mesonotum with four bristles and metanotum with six bristles. Tergites with decumbent bristles over surface plus few erect bristles toward posterior margin. Sternites with decumbent bristles over surface plus erect ones at posterior margin. Legs with two long bristles, first proximal and second at middle on external surface of all tibiae among shorter ones. Head capsule and thoracic nota whitish; digestive tube visible through abdominal sclerites. Mandibles and digestive tube, under genus description. Measurements (mm) of seven workers are given as ranges: WH, 0.48–0.50; DA–M1+2, 0.05–0.06; LT, 0.44–0.48. Ratio: WH/LT, 1.04–1.14.
