Description

Worker

Holotype. TL 2.9, HL 0.84, HW 0.73, CI 87, ML 0.35, MI 42, SL 0.42, SI 58, PW 0.37, AL 0.77. With characters of koningsbergeri-complex. Preocular concavity forms a broad depression on ventral surface of head. Upper scrobe margins more strongly divergent posteriorly than anteriorly, shallowly concave above eye; outer arc of eye visible in full-face view. Edge of upper scrobe margin irregular but without a row of triangular teeth and lacking a decidedly jagged appearance. Depression across posterior vertex of head very shallow, almost obsolete. Pronotum with a pair of short standing hairs close to anterodorsal margin. Pronotal humeral hair short and straight, stiff and simple. A single erect pair of hairs on mesonotum. Katepisternum and at least upper half of metapleuron smooth. Bullae of femoral glands absent on middle and hind legs. Lamella on propodeal declivity narrow, its posterior (free) margin concave. Standing hairs on first gastral tergite narrowly long-spatulate or their distal sections flattened and broadening to the apex; apices blunt, truncated or frayed.

Paratypes. TL 2.8-2.9, HL 0.80-0.85, HW 0.69-0.73, CI 85-87, ML 0.35-0.36, MI 42-44, SL 0.40-0.44, SI 57-60, PW 0.35-0.37, AL 0.70-0.77 (7 measured).
