Identification
Keys including this Species
Distribution
Sharaf et al. (2019): Crematogaster acaciae was originally described from Ethiopia but is also known from Democratic Republic of Congo, Somalia, South Africa, and Zambia (Guénard et al. 2017; Janicki et al. 2017). For the Arabian Peninsula, it was previously only known from Oman (Collingwood 1985; Collingwood and Agosti 1996; Borowiec 2014; Sharaf et al. 2018; Monks et al. 2019) (Fig. 6). In this study, we provide the first records for the KSA and Yemen.

Taxonomic Notes
Sharaf et al. (2019): This species represents a typical problematic taxon within the genus. The known distribution of C. acaciae and its three subspecies in the Afrotropics is patchy and there are some notable morphological differences between the infraspecific taxa. At present, it is likely that the taxonomic status of the involved taxa will change within the frame of a comprehensive revision of the Afrotropical fauna.
