A new species of Pelicinus from Barrow Island, Western Australia(Araneae: Oonopidae)

摘要

Pelicinus saaristoi sp.n., the first species of Pelicinus to be recorded from the Australasian region, is described from north-western Australia. The spider genus Pelicinus was first proposed by Simon [1891] for P. marmoratus Simon, 1891 from the Caribbean island of St Vincent. Only two other species are currently included within the genus: P. mahei (Benoit, 1979) from the Seychelles and Canary Islands, and P. vernalis (Bryant, 1945) from North America [Platnick, 2007]. The limits and relationships of the genus are poorly understood, but the morphology of the male palp suggests that the genus can be readily characterised. A fairly enlarged and rounded bulbus, a relatively short embolus with small, slender accessory sclerites and a conspicuous hump near the basal portion of the embolus [Saaristo, 2001: fig. 40B] are considered to be the main reasons for defining this genus at present.
