Pseudomyrmex holmgreni

Identification
Ward (1989) - Contrary to statements in the original description, this widespread South American species is not closely related to Pseudomyrmex filiformis. Rather, it is a member of the P. pallidus group, bearing some resemblance to Pseudomyrmex euryblemma (q.v.) but differing in the following worker characters: metanotal groove wider and more deeply incised; basal face of propodeum subequal in length to declivitous face (longer than the declivitous face in P. euryblemma); and head tending to be more elongate, with the sides rounding more gradually into the occipital margin. The workers and queens of P. holmgreni vary considerably in color, from concolorous orange to dark brown, including intermediate forms with variable degrees of infuscation of the body.
