Gnamptogenys rimulosa

Identification
Mandibles with small basal patch of costulae, rest smooth and shining; metacoxa with broad, basal lobe; petiolar node longitudinally costulate throughout; postpetiolar sternum smooth and shining. This species seems to be particularly close to Gnamptogenys regularis. Even though regularis workers lack the small laterobasal costulate area on the mandibles, females have it; there is a slight depression of the posterior mesosomal dorsum, vestigial propodeal lobes and totally longitudinal costulae on the node.(Lattke 1995)
