Pseudomyrmex obtusus

P. obtusus is known from scattered collections from Costa Rica to Peru and Brazil. Collections with habitat information come from rainforest, rainforest edge, and (Costa Rica) successional pasture near rainforest. I have made four nest collections: two from dead twigs of Ficus sp., one from a dead twig of a thorny vine, and one from a dead twig of an unidentified woody plant. (Ward, 2017)
