Identification

Sharaf et al. (2011) - Forel mentioned that the scapes of this species reach posterior margin of head, but the scapes fail to reach the margin in the syntype. In addition, he gave the funiculus segments 2-5 x broader than long. On the syntype the fifth segment is as long as or little longer than broad.

Eyes situated in the anterior third of head sides and with 6 ommatidia in the longest row (EL 0.19 x HW). Anterior clypeal margin convex and without carinae. Scapes fail to reach the posterior margin of head. Second funicular segment distinctly shorter than third. Funicular segments 2-4 broader than long, the fifth funicular segment as long as or little longer than broad. Occiput feebly concave. Mesosoma compact, short with convex pronotum and mesonotum and distinct mesonotal and metanotal grooves. Basal face of propodeum short, while its descending face long.
