Keys including this Species


Sharaf et al. (2019): Crematogaster inermis was originally described from Egypt and is widely distributed from the Iberian Peninsula through North Africa to the Middle East (Borowiec 2014; Guénard et al. 2017; Janicki et al. 2017). For the Arabian Peninsula, this species was only recorded from Yemen (Collingwood and van Harten 2001; Borowiec 20114). Knowing that it is widespread in the Mediterranean and Middle East and the only record for the Arabian Peninsula is from Yemen, we think that it is likely that it is also present in the KSA. Futher sampling is necessary to verify this.

Borowiec & Salata (2020): This taxon was recorded from Cyprus, Egypt, Iran, Israel, Syria, Yemen, Libya and Morocco but some of these records need confirmation. Additionally, records from Jordan need to be confirmation.

Taxonomic Notes

Recent material suggests that this is a group of cryptic taxa. Borowiec & Salata (2020) compared their material of this group from Jordan with type of Crematogaster warburgi and they appear to be conspecific.
