Holcoponera porcata

A dweller of premontane to montane humid forests. J. Longino (pers. comm.) found an incipent nest in Cecropia insignis. One nest midden contained mostly the remains of beetles: scotylids, bostrichids, curculionids, besides isopods. Nests from one population (Venezuela, Tachira) consistently had their brood chambers irregularly wall-papered with the remains of pupal cocoons.

Identification
A member of the porcata subgroup (in the striatula species group). Costate species, median longitudinal costae on pronotum inscribed anteriorly by transverse costae; posterodorsal mesosomal sculpture variable: concentric ovaloids with longitudinal or transverse orientation, or with longitudinal costae inscribed within whorls; piceous body with ferruginous legs. The study of a series from Venezuela representing several colonies from different populations show great variability for dorsal mesosomal sculpturing. (Lattke 1995)
