Taxonomic history.

Crematogaster mimosae Santschi, 1914a: 87, fig. 11 (w.) Kenya: Menozzi 1939: 105 (q.).

Combination in Crematogaster ( Crematogaster): Wheeler 1922: 841; in Crematogaster (Acrocoelia): Emery 1922: 148; in Crematogaster ( Crematogaster): Bolton 1995: 166.

Current subspecies: C. mimosae tenuipilis Santschi.

Geographic range.

Initially described from Kenya, in the Afrotropics this species is East African in its distribution found in Kenya, Uganda, Somalia, Sudan, and Tanzania ( Guénard et al. 2017; Janicki et al. 2017). In the Arabian Peninsula, it was recorded from the KSA, Oman, the UAE and Yemen (Collingwood 1985, Collingwood and Agosti 1996; Borowiec 2014; Sharaf et al. 2018) (Fig. 25).

Remarks.

Crematogaster mimosae is one of four species of obligate acacia ants, which have been well studied in East Africa, mostly Kenya (e.g., Young et al. 1997; Martins 2010). From a taxonomic perspective, this is one of the “easy” cases within the genus in Arabia, thus very straightforwardly identifiable.
