Description
Worker
Bolton (2000) - TL 3.6, HL 0.98, HW 0.70, CI 71, ML 0.49, MI 50, SL 0.64, SI 91, PW 0.41, AL 0.88. Pair of standing hairs on cephalic dorsum close to occipital margin, and pair on mesonotum, short and narrowly spatulate. Waist segments and first gastral tergite without erect or elongate standing hairs of any form; instead the tergite densely clothed with short soft hairs that are simple to extremely narrowly spatulate, nearly reclinate and directed medially or posteromedially. Leading edge of scape with short bristle-like to spatulate stubbly hairs, some of which are at right-angles to the long axis of the shaft or inclined toward the base of the scape; not all hairs curved or inclined toward apex of scape. Spongiform lobes of both waist segments all well developed. Cephalic dorsum finely and densely reticulate. First gastral tergite covered with dense sharp longitudinal costulae from base to apex, without basigastral costulae that are differentiated from this sculpture.
