Distribution Notes:

Costa Rica, Nicaragua, Honduras. In Costa Rica: mid-elevation Atlantic and Pacific slopes, Cordillera Volcanica Central northward.


Brown and Wilson (1959) summarize the genus as follows:

"Widespread in tropics and warm temperate areas. Primarily forest-dwelling; some species occur in grassland and arid scrub. ... Nests mostly in soil and rotting wood; a few species live in arboreal plant cavities in tropical rain forest. Foraging hypogaeic to epigaeic-arboreal. Food: most species are collembolan feeders; a few are polyphagous predators or occasionally feed on sugary substances..."

Members of the genus are all predaceous, with a kinetic mode of attack (Bolton 1999).

In Costa Rica, nevermanni occurs in wet forest habitats. It nests and forages in the low arboreal zone and in some cases in litter on the forest floor.


Differs from emeryi in part or all of side of propodeum foveolate; foliaceous crest beneath propodeal spines thin, concave; foliaceous crest on ventral margin of petiole thin; dorsal pilosity on gaster straight to weakly curved, never long and coachwhip-like. In contrast, emeryi has completely smooth and shining katepisternum and side of propodeum; large convex foliaceous crest beneath propodeal spines; foliaceous crest on ventral margin of petiole large, irregular; dorsal pilosity on gaster varies from straight to long, thin, coachwhip-like.


Strumigenys emeryi and nevermanni are largely parapatric, with a zone of sympatry along the Caribbean coast of Honduras. Although similar, they fall into two DNA barcode clusters.
