Synonyms

Crematogaster rothneyi is known from South Asia to Southeast Asia, making it one of the most widely distributed ant species in Asia. However, the species is rarely encountered in the field (Hosoishi & Ogata, 2019).

Identification

This species is very similar to Crematogaster yaharai, but can be distinguished by the broader than long antennal segments V to VI, sculptured mesopleuron, and reticulately or areolately sculptured propodeum. The Indian specimen examined does not have distinctly developed longitudinal rugulae on the higher half of the dorsal surface of the head. The Thai specimens have broader or as broad as long antennal segments V and VI and a sculptured propodeal dorsum (Hosoishi & Ogata, 2019).

Taxonomic Notes

The syntype workers of C. rothneyi civa match well with syntype workers of C. rothneyi. We treated C. rothneyi civa as a junior synonym of C. rothneyi (Hosoishi & Ogata, 2019).
