Identification

Fernández (2003) - Adelomyrmex samoanus can be separated from other species by the sculpturing of the body (head sub-opaque with longitudinal rugulae, smooth pronotum with few and weak rugulae), mesosomal configuration, and the pilosity (reclining on the head, erect on the rest of the body). This species is known solely from Western Samoa.
