This species is only known from a single collection made in dry rainforest.

Identification

Shattuck (2011) - Hairs on head and body thin (essentially the same width along entire length, or only slightly and gradually expanded distally, and with blunt tips), propodeum lacking spines and gaster with low longitudinal striations. This species shares the longitudinal striations on the gaster with Calyptomyrmex fragarus and Calyptomyrmex retrostriatus but differs from fragarus in having thin rather than spatulate hairs and from retrostriatus in being larger (head width > 1.20mm vs. head width < 1.00mm in retrostriatus.

Description

Worker

(holotype) - CFW 0.25; CI 103; HL 1.24; HW 1.28; ML 1.22; MTL 0.59; PetI 144; PetL 0.30; PetW 0.44; PronW 0.86; SI 58; SL 0.74.

Mandibles striate basally, essentially smooth apically. Eyes with 4 ommatidia in greatest diameter. Propodeum in lateral view lacking angles or spines. Propodeal lobes thin anteriorly, thickened posteriorly. Node of petiole in profile slightly higher than that of postpetiole, both approximately the same volume. In dorsal view the petiolar node slightly narrower than the postpetiolar node. Head rugose anteriorly and foveolate posteriorly, with spaces between rugulae indistinctly shagreened or finely reticulate-punctulate. Mesonotum longitudinally rugose, superimposed over indistinct shagreening. Side of mesosoma a matrix of large circular fovae-like pits and short longitudinal rugae, the entire surface superimposed with indistinct punctations. Dorsum of petiolar and postpetiolar nodes foveolate. Gaster foveolate anteriorly fading to longitudinally rugose posteriorly, the underlying surface indistinctly and irregularly punctate. Hairs on head and body erect, uniform in diameter with most narrowing slightly towards the base, and most on the mesosoma slightly swollen medially; generally with sharply pointed tips. Clypeal fork with slightly enlarged and thin hairs, all hairs approximately the same length. Colour red- brown, antennae and legs slightly lighter.
