The alien synanthropic Salticidae in Brazil (Araneae)

ABSTRACT Salticidae is the most diverse family of Araneae and in Brazil, there are 667 species. Among these species, five are synanthropic exotics: Plexippus paykulli (Audouin, 1826), Hasarius adansoni (Audouin, 1826), Menemerus bivittatus (Dufour, 1831), M. nigli Wesołowska & Freudenschuss, 2012 and Thyene coccineovittata (Simon, 1886). To understand the current distribution of these species in Brazil, seven collections of 643 lots were examined from seven Brazilian zoological collections. The synanthropic exotic species with the highest records were Plexippus paykulli, Menemerus bivittatus, and Hasarius adansoni, generally collected and associated with human dwellings and buildings. They are present in all regions (North, Northeast, Midwest, and South macro-regions), with the largest region, in all regions of the country in 22 states and 98 municipalities, followed by Hasarius adansoni in 17 states and 88 municipalities, Menemerus bivittatus in 19 states and 68 municipalities. Menemerus nigli and Thyene coccineovittata are from recent introductions that occurred in the city of Rio de Janeiro, Rio de Janeiro, Brazil.
