Description

Worker

Bolton (2000) - Holotype. TL 2.3-2.6, HL 0.66-0.72, HW 0.45-0.49, CI 66-70, ML 0.28-0.30, MI 40-43, SL 0.38-0.40, SI 78-84, PW 0.25-0.29, AL 0.68-0.72 (10 measured).

Characters of mjoebergi-complex. Just proximal of the preapical tooth the lower border of the inner margin of the mandible projects farther toward the midline than does the upper border; in full-face view the lower border is therefore visible, projecting as a narrow convex arc beyond the line of the upper border. Apicoscrobal hair short, usually with 1-2 similar but even shorter projecting hairs posterior to it on dorsolateral margin. With head in full-face view the ventrolateral margin just visible behind the level of the eye. Cephalic dorsum with 4-6 stiffly erect short hairs close to the occipital margin, head without other standing hairs. Pronotal humeral hair simple. Pronotal dorsum and mesonotal dorsum each with a single pair of short erect hairs. Side of alitrunk entirely reticulate-punctate. Lateral spongiform lobe of petiole small, in profile restricted to posterior margin of node. Disc of postpetiole finely reticulate-punctate and with fine longitudinal costulae. Basigastral costulae as long as or somewhat longer than disc of postpetiole but not extending half the length of the tergite. First gastral tergite with stiff straight short hairs, weakly remiform and suberect to erect; second tergite with pilosity as first, without flagellate hairs.

Type Material
