Abstract

Seven new species of the spider genus Ochyrocera from cave areas in Floresta Nacional de Carajas (state of Para, northern Brazil) are described: Ochyrocera varys sp. n., Ochyrocera atlachnacha sp. n., Ochyrocera laracna sp. n., Ochyrocera aragogue sp. n., Ochyrocera misspider sp. n., Ochyrocera charlotte sp. n., and Ochyrocera ungoliant sp. n. Two groups of the species are discussed, the quinquivittata group that include specimens with an apparently bifid retrolateral apophysis in the cymbium of the male palp and the arietina group, here proposed, that include those specimens with an entire cymbium, with no retrolateral apophysis, in the male palp. Although these species were abundant inside caves, the examined specimens do not have troglomorphic characteristics and can be classified as edaphic troglophile species, capable of completing its life cycle in soil, shallow subterranean habitats, or caves.
