Crematogaster antaris

This is a very widespread and common species, which appears to be one of the most arid-adapted species within the genus (Sharaf et al., 2019).

Identification
Collingwood and Agosti (1996) - HW 1.08-1.45; C1 104-114; PL/PW 0.68-0.715. Crematogaster aegyptiaca is sometimes as red as the deserticolous C. antaris but is usually darker, more rugose and pubescent; the petiole is wider with the anterolateral corners produced and wing-like in full dorsal view. Queens of C. antaris are larger, have the head and alitrunk red and have characteristic lateral striae on the occiput.

Distribution
Sharaf et al. (2019): Originally described from Algeria, C. antaris is also found in Morroco, Tunisia, Egypt, and Iran (Sharaf 2006; Paknia et al. 2008; Vonshak and Ionescu-Hirsch 2009; Borowiec 2014; Guénard et al. 2017; Janicki et al. 2017). Its apparent absence in Libya is likely a sampling artifact. Crematogaster antaris is also broadly distributed in the Arabian Peninsula where it is known from Kuwait, Oman, the KSA, the UAE, and Yemen (Collingwood 1985; Tigar and Collingwood 1993; Collingwood and Agosti 1996; Collingwood et al. 2011; Borowiec 2014; Sharaf et al. 2018).
