Worker. Measurements (mm), holotype in parentheses: HW 0.90 - 0.94 (0.94); HL 1.00 - 1.04 (1.04); SL 0.94 - 0.98 (0.97); EL 0.19 - 0.20 (0.19); MSL 0.08 - 0.10 (0.10). SL / HL 0.93 - 0.96 (0.93). Number of ommatidia along the long axis of eye ca 10.
Structure. Head slightly longer than wide, almost parallel-sided behind eyes, with the posterior margin almost straight in full-face view. Clypeus with the anterior margin widely and very shallowly emarginate. All the funicular segments of antenna longer than wide. Antennal scape surpassing the posterior margin of head by less than 1 / 4 of its total length in full-face view. Anterodorsal corner of pronotum weakly and roundly produced; mesonotum demarcated anteriorly from pronotum by a wide and deep furrow; mesopleuron above sometimes with a weak transverse groove; metanotal depression distinct. Propodeum in profile separated by a distinct furrow from metapleuron and propodeum; posterior face distinctly margined laterally. Sculpture. Dorsum of head finely and densely punctate. Clypeus almost smooth except in median portion that is longitudinally and finely striate. Mandible extensively smooth with large sparse punctures, and only basal portion finely striatopunctate. Dorsum of pronotum finely punctate; its lateral face and mesonotum with still finer punctation; mesopleuron and metapleuron smooth and shining, with rugulae in lower posterior area. Propodeum dorsally irregularly sculptured but its lateral face smooth; posterior face of propodeum smooth except for margins and upper portion. Petiole anteriorly micropunctate, posteriorly smooth. Gastral segments finely punctate and somewhat shining. Pilosity. Body covered with decumbent pubescence except for mesopleuron, metapleuron, and posterior faces of propodeum and petiole that are almost bare. Dorsum of head, mesosoma, petiole almost without standing hairs; disc of gastral tergites 1 and 2 with a few standing hairs in addition to those at posterior margins; other tergites and sternites also with standing hairs at margins. Coloration. Mesosoma jet black; head, petiole and gaster blackish brown. Antennal funiculus and mandible brown to reddish brown. Legs yellowish brown to orangish, strikingly contrasting with jet black mesosoma.
ETYMOLOGY
Named for the yellow legs of this species.
REMARKS
This species has the shortest relative length of antennal scape among the species treated here. The scape surpasses the posterior margin of head by less than 1 / 4 of its total length.
