Tetramorium sudanense

Identification
angulinode group

From Bolton (1980)

''The holotype and only known specimen of this species is not present in AMNH, New York; LACM, Los Angeles; USNM, Washington or MCZ, Cambridge (where the main part of the Weber Collection is housed). The original description gives a picture of a species in the angulinode group with measurements close to the bottom end of the range of angulinode itself (TL 2.3, AL O.64) and generally bearing a close resemblance to the species. The following differences culled from Weber's description may be of importance.

1. Head slightly longer than broad.

2. Eyes closer to occipital than to clypeal margin.

3. Petiole with a massive squarish node, longer than broad in dorsal view.

4. Pedicel segments reticulate-punctate; postpetiole with a smooth median area.

There is not enough information given to pin down this species with any degree of accuracy and for this reason it has been omitted from the key. The only course which can be taken at present is to treat the name as a nomen dubium until the holotype is found (if that is possible) or until extensive collections can be made at the type-locality which may give some clue to the real identity of this species.
