Pheidole koshewnikovi

Distribution
Khalili-Moghadam et al. (2019) report the first record of P. koshewnikovi from Iran. According to the recent revision of the Pheidole pallidula species-group (SEIFERT 2016), however, all previous Iranian records of Pheidole pallidula probably relate to P. koshewnikovi, which is the species with the easternmost distribution of this group.
