Abstract

New data on the jumping-spider genus Arnoliseus are presented. Three new species from the Atlantic Forest in Rio de Janeiro state are described, based on both sexes: Arnoliseus carioca sp. nov. from the city of Rio de Janeiro, and Arnoliseus hastatus sp. nov. and Arnoliseus falcatus sp. nov. from the municipality of Cachoeiras de Macacu. The genus’ genital morphology is discussed in detail and new English terminology for their structures is created. An identification key for all Arnoliseus species is given.
