DESCRIPTION. Dimorphism in worker caste. Major worker. Head larger than thorax; frons with longitudinal striation; frontal carinae with 3 pairs of erect hairs; mandible relatively short, subtriangular, masticatory margin with 5 teeth (including large apical tooth); antenna

11-segmented with 2-segmented club; antennal scape thin (clavate, its apical portion narrower than or broad as long as antennal segment X); promesonotum in profile view distinctly convex to form a dome; promesonotal suture indistinct; metanotal groove distinct; propodeum distinctly lower than promesonotum; propodeal spine short, usually shorter than its base; petiole,

in profile, with long anterior pedicel; postpetiole clearly shorter than petiole; Gastral tergite I clearly large than remaining segments. Minor worker. Head small, smooth and shiny; mandible relatively short, subtriangular, masticatory margin with 5 teeth (including large apical tooth); eye very small, present as a dot; antenna 11-segmented with 2-segmented club; antennal scape thin (clavate, its apical portion narrower than or almost as broad as antennal segments

X); promesonotum in profile view convex, smooth and shiny; promesonotal suture absent;

metanotal groove distinct; mesopleuron and propodeum largely punctate; propodeal spine absent; petiole, in profile, with long anterior pedicel; postpetiole clearly shorter than petiole;

Gastral tergite I clearly large than remaining segments. Dealate geny. Head smaller than mesosoma; frons with longitudinal striation; eye large and convex; three ocelli present on vertex; pronotum in profile placed in vertical, subrectangular, shorter than mesoscutum;

masoscutum large, located higher than pronotum, subtrapezoidal, its anterior margin strongly convex; parapsidal line long; propodeal spine short; petiole, postpetiole and gaster as in major workers.
