Taxonomic Notes
Pashaei Rad et al., 2018: Cataglyphis rockingeri, CASENT0911109, where it is listed under C. aenescens (Nylander). Type location Kazakhstan. The type and the Iran workers are larger than what seems likely to be the type form aenescens and is uniformly dark rather than having lighter reddish areas; the overall appearance is almost silky due to the fine very spiculate sculpture.

Note that Bolton (in his unpublished An online catalogue of the ants of the world, 15 Feb. 2020) does not recognise the species status proposed by Pashaei Rad et al. (2018), noting that "the entries in this publication are omitted from the catalogue as it contains numerous nomenclatural errors; it also ignores previous taxonomic decisions, and entirely fails to apply ICZN rules that govern the availability of names in the species-group." Additionally, it should be noted that Pashaei Rad et al. (2018) provide minimal evidence to support their treatment of C. rockingeri as a distinct species.
