Meriola arcifera
Meriola arcifera is a species of true spider in the family Trachelidae, first described by Simon in 1886. It is native to South America, with confirmed records from Chile, Bolivia, and Argentina. The species has been introduced to several regions outside its native range, including the United States (California and Hawaii) and Chilean offshore islands (Easter Island and Robinson Crusoe Island). Its establishment in these areas suggests human-mediated dispersal, though specific introduction pathways remain undocumented.
