  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.

Abstract

Three new species of Alpaida O. Pickard-Cambridge, 1889 are described from the Brazilian Amazon region: Alpaida tukano sp. nov., A. kayapo sp. nov. and A. tupinamba sp. nov. Alpaida murtinho Levi, 1988 is newly synonymized with A. guimaraes Levi, 1988 and the male originally associated with A. guimaraes is redescribed as A. tupinamba sp. nov. The true male of A. guimaraes is redescribed, and the male of Aculepeira apa Levi, 1991 is described for the first time.
