Tetramorium nullispinum Bolton

Type location Nigeria (Bolton, 1980, not illustrated; one worker, from IITA, Ibadan; by B.R. Critchley, 11-18.xi.1974). .

Bolton's description (1980) is at .

TL 2.4 mm; the only 11-segmented species with no propodeal armament known from Africa. All dorsal surfaces with numerous short, fine, acute hairs. Colour mid-brown, the gaster blackish brown (Bolton, 1980). This was noted as synonymised with Tetramorium angulinode by Bolton (1995) but the detailed description in his 1980 paper has many differences.

The photomontage of the holotype worker is collated from http://www.antweb.org/specimen.do?name=casent0901162. The propodeal spines, or rather lack of spines, appears to be identical on both sides and the images show no sign of "broken" spines.
