Scorpiones Solifuge Pseudocleobis mauryi sp. nov. Pseudocleobis profanus sp. nov. taxonomy ctenidia flagellum chaetotaxy


Two new solifuge species of the genus Pseudocleobis (Solifugae, Arachnida) from northern Patagonia and southern Monte desert biogeographical regions are described: P. mauryi sp. nov. and P. profanus sp. nov. New records of P. huinca Maury, 1976, P. bardensis Maury, 1976 and P. solitarius Maury, 1976 are provided. The female of P. solitarius is described based on specimens from the type locality. SEM photographs, schemes of diagnostic characters, and maps of the known distributional records are provided for the five species treated here. Pseudocleobis profanus sp. nov. is closely related to P. huinca and P. bardensis, and the three species may form a species group characterized by the peculiar morphology of the male movable finger mucron and the flagellum. Ctenidia on male sternite III and IV are reported for the five species.
