Comprehensive DescriptionRead full entry
Solenopsis papuana is a minute pale yellow species with 10-segmented antennae, two-segmented antennal clubs, no antennal scrobes, minute eyes, no propodeal spines, unsculptured heads and bodies, abundant thin and erect pilosity, and a monomorphic worker caste. Like all myrmicines, S. papuana has a two-segmented waist and a gaster armed with a stinger. Solenopsis papuana is a small species, but nests will recruit in vigorous force to baits and food resources. They can defend the bait from competing ants with use of their stings. The species occurs both in urban landscapes and natural forests.
