This is a non-trail forming species living in small communities (Collingwood and Agosti 1996). Pashaei Rad et al. (2018) found this species in Iran in garden soil in a low rainfall area.


Collingwood and Agosti (1996) - HW 1.7; EL/HW 0.21. This interesting species stands apart from other Middle Eastern Messor species because the antennal segments are exceptionally thin and the nodes are comparatively low.

Keys including this Species
