Full Range: Throughout mainland tropical America from southern Brazil to southern Mexico, on many Caribbean islands, and in southern Florida.
Costa Rican Range: Atlantic and northern Pacific lowlands (possibly exotic, see below).
Strumigenys eggersi Emery 1890:69, pl. 7, fig. 9. Syntype worker, queen: Antilles Islands, St. Thomas Island (Eggers) [NMV, MZSP, USNM].
Later moved to Pyramica. See Bolton (2000) for complete synonymy.
Members of the genus are all predaceous, with a static pressure mode of attack (Bolton 1999).
Brown (1960) reported
Weber found specimens in a compost heap in the Botanical Garden at Roseau, Dominica, and in an island of vegetation growing in the Pitch Lake of Trinidad; also on Trinidad, he took a sample from low-growing epiphytes in second-growth forest. Kempf sifted specimens from humus in Sao Paulo. Indications are that this species can stand more dryness than many dacetines, and its presence in many culture areas suggests that it is spreading rapidly through nursery stock transport and other human commerce.
He suggested that southern Brazil and Bolivia was its home range, and that elsewhere it had been introduced.
In Costa Rica this species appears rare, although my collecting has not emphasized dry and/or synanthropic habitats. I have encountered it in Winkler samples from Finca La Pacifica (riparian forest in seasonally dry region), and La Selva Biological Station (lowland rainforest).
