Strumigenys silvestrii Emery, 1906

Distribution. Argentina to Guyana; introduced in USA, Mexico, most Caribbean Islands and Portugal; in eastern USA from Florida to North Carolina and west to Louisiana; in western USA occurs in California and Texas.

Comments. Strumigenys silvestrii is a native to tropical and subtropical South America and has been introduced to the USA, Mexico, and Portugal (MacGown et al. 2012; Guénard et al. 2017). Although ranging across all southeastern Atlantic Gulf states, it is not commonly collected across its USA range. This species inhabits drier more open habitats than most Nearctic species and is often picked up in pitfall traps or flight traps in areas with little leaf litter accumulation. Fewer collectors have recorded this species occurring in heavily forested habitats. Both males and queens have been collected for this species, with mating flights in Texas between late May and mid-July (estimated from alate collections). The earliest record from Texas is 1969 and from California is 1996 (MacGown et al. 2012).
