Gnamptogenys alfaroi

Known from mountane rain forest.

Identification
A member of the alfaroi subgroup (in the mordax species group). This species is a striking member of the mordax group due to its elongated, almost cylindrical body. Its relationship with other members of the mordax group is not clear. Mandibular dorsum smooth and shining with some punctulae; metacoxal spine present; subpetiolar process anteriorly projected ; gastric tergum 2 with basal one-half longitudinally costulate, the rest smooth and shining; disk of pospetiolar sternum smooth and shining; body black; legs and antennae brown. It is rarely collected. (Lattke 1995)
