A review of the Chilean spider genus Olbus, with notes on the relationships of the Corinnidae (Arachnida, Araneae)

The Chilean spider genus Olbus is revised to include five species: Olbus sparassoides (Nicolet), and four new species, O. jaguar, O. nahuelbuta, O. eryngiophilus, and O. krypto. The genus is diagnosed by the presence of one apical thickened seta on the palpal tarsus. Differing from the subfamilies C...
