Specimen labels

Found in humid forests of lowlands and mountains (cloud forest). Taken from leaf litter samples and beneath bark of rotting logs on ground. (Lattke 1995)

Identification

A member of the mordax subgroup (in the mordax species group). Sublinear mandibles. Cephalic dorsum, mesosoma, and gastric tergum I with longitudinal costulate; gastric tergum II smooth; pleura also with smooth patches; metacoxal tooth absent. Body reddish brown; legs and antennae ferruginous. Lateral mesosomal costulate can be effaced to a variable degree and the second gastric segment can ocassionally have weak longitudinal costulae, medianly effaced. Declivitous propodeal face with longitudinal costulae and weakly developed anterolateral lobes. (Lattke 1995)

Biology

Explore-icon.png Explore Overview of Gnamptogenys biology 
Not much is known about the the biology of Gnamptogenys interrupta. We can speculate that the biology of this species is similar to other species of the genus. Gnamptogenys are predatory ponerine ants that inhabit tropical and subtropical mesic forests. Nesting is typically at ground level in rotten wood or leaf litter. Some exceptions include species that are arboreal, a dry forest species and species that nests in sandy savannahs. Colony size tends to be, at most, in the hundreds. Queens are the reproductives in most species. Worker reproduction is known from a few species in Southeastern Asia. Generalist predation is the primary foraging/dietary strategy. Specialization on specific groups (millipedes, beetles, other ants) has developed in a few species.
