Calyptomyrmex ocullatus

This rare species has been collected only once, from a rainforest in Far North Queensland. No further details are available.

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 armed with short spines, mesonotum rugo-reticulate but lacking longitudinal rugae, petiolar node narrow and thick in dorsal view. This species is similar to Calyptomyrmex grammus but differs in lacking longitudinal rugae on the mesonotum (these are present in grammus) and in having a narrower and thicker petiolar node.

Mandibles striate basally, essentially smooth apically. Eyes small, with 2–3 ommatidia in greatest diameter. Propodeum in lateral view armed with short spines. Propodeal lobes slightly thickened posteriorly. Node of petiole in profile higher and larger than that of postpetiole. In dorsal view the petiolar node approximately the same width as the postpetiolar node. Head indistinctly rugose, the rugae tending to be longitudinal anteriorly and forming a weak network posteriorly, with the entire surface finely but distinctly punctate, the punctations partially obscuring individual rugae. Mesosoma and petiolar and postpetiolar nodes rugose superimposed over an indistinctly punctate background, the individual rugae wavy and sometimes forming a network, otherwise more or less linear. Gaster finely and indistinctly sculptured, stronger anteriorly and fading slightly posteriorly. Hairs on head and body erect, uniform in diameter and with sharply pointed tips. Clypeal fork with slightly enlarged and thin hairs, all hairs approximately the same length. Colour yellow-red, antennae, legs and base of gaster slightly lighter.
