Description

Worker

Bingham (1903) described as Ponera truncata: Dark castaneous brown, densely reticulate, punctate aud pubescent ; the mandibles, antennae and legs pale reddish brown. Head nearly transverse posteriorly; eyes comparatively large; mandibles with an extremely broad masticatory margin; clypeus carinate, the carina bifurcate anteriorly. Thorax as long as the abdomen, above slightly emarginate at the meso-metanotal suture, the metanotum slightly compressed. Node of the pedicel flat, very much broader than long, but distinctly thick and rounded above, not with a sharp margin; abdomen with the constriction between the basal two segments well marked; sting exserted.

Length: 3 - 3.5 mm

Smith (1860): Black; the clypeus, antennæ, mandibles, legs, the apex of the metathorax and of the abdomen ferruginous; the eyes placed forward at the sides of the head, near the base of the mandibles; the head, thorax, and abdomen thinly covered with a fine, short, downy pile, which renders the body sub-opake; the truncated portion of the metathorax very smooth and shining; the mesothorax with an obscure rufous tinge. The apical margins of the two basal segments of the abdomen rufo-testaceous, the following segments entirely so.
