Holotype major: TL 5.7, HL 1.70, HW 1.76, CI 103, SL 0.97, SI 55, PW 0.97, AL 1.78, ED 0.21.

Head broader than long, occipital border angularly deeply concave, median groove distinct. Masticatory margin of mandible with 5 teeth, 4th and basal teeth combined at base. Median part of anterior clypeal border straight, each side with one blunt tooth. Antennal scapes reaching 3/4 of the length from their insertion to occipital corners. Eyes small, flat, situated before midlength of the sides of head. Pronotum convex, promesonotal suture impressed; mesopropodeal suture deeply impressed; basal face of propodeum short, declivity 1. 6 X as long as the basal face. Petiolar node cuneiform, slightly concave in the middle of upper border. Gaster slightly longer than head.

Mandibles smooth and shining. Head, ali trunk, petiolar node and gaster densely finely punctate.

Erect hairs golden yellow, abundant. Pubescence greyish white, abundant.

Color yellow. Vertex, dorsum of alitrunk and gaster slightly contaminate brown.

Paratypes 2 major: TL 5.2~5.8, HL 1.79~1.82, HW 1.82~1.93, CI 101~106, SL 1.00~1.06, SI 53~55, PW 0.97~1.07, AL 1.76~1. 82, ED 0.22~0.25.

Paratypes 10 median and minor: TL 3.0~4. 9, HL 0.78~1.25, HW 0.73~1.21, CI 94~97, SL 0.70~0.94, SI 77~93, PW 0.48~0.72, AL 0.96~1.41, ED 0.10~0.13. Head longer than broad, with slightly concave occipital border, mandibular teeth acute, anterior clypeal border convex, antennal scapes extending beyond occipital corners, median groove of vertex indistinct. Other characters as in major worker.
