Tetramorium convexum species group
Based on Bolton 1980.
Key to species of the Afrotropical Tetramorium convexum species group.
Diagnosis
Antennae with 12 segments. Sting appendage triangular or dentiform. Mandibles smooth and shining with scattered pits. Anterior clypeal margin entire, without a median notch or impression. Frontal carinae very short (convexum) or absent (wadje). Antennal scrobes absent. Antennal scapes short, SI 68-75. Eyes of moderate size. the maximum diameter 0·24-0·27 x HW. Propodeum absolutely unarmed or with a pair of short teeth. Petiole nodiform, with a slight thick anterior peduncle: in dorsal view node slightly broader than long. Pilosity consisting of numerous fine standing hairs which are acute apically (convexum) or of minute appressed hairs only (wadje), never with short stout, apically blunt hairs. Appendages without standing long hairs, either with short appressed or suberect-subdecumbent pubescence.
Notes
The two small species placed in this group are put together for convenience and do not appear to be related. Neither of them is obviously related to any known group of Tetramorium and their affinities are unclear. Reasons for isolating them from various groups with which they seem to have affinities are given under the species diagnoses.
