  A New Species of Scorpio from Saudi Arabia (Scorpiones: Scorpionidae)  Abstract A new species of  Scorpio  Linnaeus, 1758 is described from Al Ula Governorate, Al Madinah Province, Saudi Arabia.  Scorpio furvus  sp. nov. is distinguished from closely related congeners, including  S. fuscus ,  S. kruglovi ,  S. palmatus ,  S. jordanensis , and  S. yemenensis , by a unique combination of morphological characters notably the granulation pattern of the pedipalp chela, metasomal proportions, pectinal structure and length, and overall dark coloration. Morphometric comparisons further support its distinct status. The discovery of this species highlights the underestimated diversity of the genus  Scorpio  in the Arabian Peninsula and reinforces the view that the  Scorpio maurus  complex comprises multiple geographically restricted taxa requiring continued integrative taxonomic investigation.

Two new species of the genus Cladothela (Araneae: Gnaphosidae) from Nansei Islands, southwest Japan, with the description of the true female of C. auster

Abstract
Examinations of spiders of the gnaphosid genus Cladothela collected from Nansei Islands, Japan revealed that two undescribed species of the genus occur in the area, and that in C. auster Kamura 1997, the previous understanding of the combination of male and female is incorrect. Two new species, Cladothela notus n. sp. and C. sakishima n. sp., and the true female of C. auster are described.
