Polyrhachis spitteleri Forel

Polyrhachis spitteleri Forel, 1916: 450 , fig. 6. Holotype worker, DEMOCRATIC REPUBLIC of the CONGO (locality unknown) (H. Kohl) (MHNG) [not seen].

Diagnosis. The monista -group species with hardly impressed promesonotal suture and a tubercoliform prominence between the propodeal spines.

I assign to this species a gyne from Central African Rep. It has a weak median prominence between the long propodeal spines as reported for the worker caste (Bolton, 1973). The dorsum of mesosoma is mostly longitudinally rugulose with reticulate-punctate ground sculpture. The remaining of the body is more or less strongly reticulate-punctate and subopaque; mandibles, clypeus and gaster are superficially sculptured and shining.

Measurements. HL 1.42, HW 1.30, CI 92, SL 1.43, SI 110, FW 0.55, FI 42, ScW 1.40, MnL 1.65, WL 2.24, HTL 1.68.
