Diagnosis

The morphometric profile of this species is unique. Minor worker: the combination of uniformly foveolate face and mesosoma, lack of promesonotal groove, very long posteriorly-directed propodeal spines, long scapes, and orange color is distinctive. Major worker: the combination of strongly cordate head, long scapes, uniformly foveolate sculpture over most of face, long propodeal spines, and orange color is distinctive.

Head cordate; mandible smooth and shiny; clypeus shining, smooth with weak median carina, 2-3 more prominent carinae anterior to frontal carinae, anterior margin straight but with small semicircular impression; face with longitudinal rugae between frontal carina and compound eye and between frontal carinae, rest of face foveolate; head with abundant suberect setae projecting from sides of head in face view; scape smooth and shining or minutely rugulose, terete at base, with abundant erect setae longer than maximum width of scape; hypostomal margin straight; a small blunt median tooth present; inner hypostomal teeth distinct, closer to midline than to outer hypostomal teeth; promesonotal groove indistinct; propodeal spines present, large; mesosoma largely foveolate; dorsal (outer) margin of hind tibia with abundant erect setae, some longer than maximum width of tibia; pilosity abundant on mesosomal dorsum; first gastral tergite smooth and shining, with abundant erect setae; color orange.

Biology

This species occurs in mid-elevation wet forest. It is known from one collection, a nest under epiphytes in a less than 1-month old treefall.
