Leptomyrmex garretti

This rainforest species nests under rocks. It forages on the ground and on vegetation.

Identification
Scapes long (SI > 174, Fig. 20); pubescence short sparse and adpressed; petiolar node weakly convex in anterior view; anterior mesonotum without a raised hump. Sympatric with Leptomyrmex dolichoscapus and Leptomyrmex pilosus it is more widespread than these and readily separated from them by the combination of normal length scapes and normal pilosity.
