Pseudomyrmex euryblemma

Identification
Ward (1989) - P. euryblemma is a common and widespread species, whose laterally angulate median clypeal lobe (in workers and queens) and anteroventrally recurved pygidium (in males), clearly place it in the P. pallidus group. Workers of this species have a broad head (HW 0.81-0.98, CI 0.86-0.92; n=14) whose puncticulate-coriarious sculpture weakens towards the vertex (which is sublucid); wide but shallow metanotal groove; long basal face of the propodeum; and pubescent fourth abdominal tergite. The propodeal spiracles are rather salient in dorsal view, and individuals are typically dark brown in color.
