Calyptomyrmex taylori is known from numerous collections made within a tiny area near Cape Tribulation, Cape York Peninsula, Queensland. All collections have been from rainforest leaf litter.

Identification

Shattuck (2011) - Hairs on head and body spatulate (noticeably narrower near the body and expanded distally and with a rounded tip), gaster indistinctly punctate, propodeum unarmed, in dorsal view node of petiole rectangular, body smaller (head width < 0.85mm).

Within Australia, taylori is most similar to Calyptomyrmex beccarii but differs in having narrower spatulate hairs on the head, a more rectangular petiolar node (in dorsal view) and in being smaller (head width < 0.85mm rather than > 0.90mm).

Worker

(n = 10) - CFW 0.09–0.11; CI 92–97; HL 0.76–0.83; HW 0.72–0.80; ML 0.70–0.81; MTL 0.31–0.38; PetI 174–201; PetL 0.17–0.20; PetW 0.33–0.36; PronW 0.49–0.55; SI 58–64; SL 0.44–0.51.

Mandibles striate. Eyes with 4–5 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 and larger than that of postpetiole. In dorsal view the petiolar node much broader than long and slightly narrower than postpetiolar node. Head weakly rugose, the rugae enclosing foveolate spaces, the underlying surface indistinctly punctate. Promesonotum, sides of mesosoma and dorsum of petiole and postpetiole with ill- defined longitudinal rugae which are slightly stronger laterally than dorsally. The underlying surface of the mesosoma, petiole, postpetiole and gaster indistinctly punctate. Hairs on head and body narrowly spatulate and raised above the surface of the body. Clypeal fork with enlarged, short and thin, elongate hairs. Colour dull red-brown, antennae and legs slightly lighter.
