A New Species of Scorpio from Saudi Arabia (Scorpiones: Scorpionidae)

  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.

Unveiling high solifuge diversity: Review of the genus Pseudocleobis Pocock, 1900 (Ammotrechidae) in Chile with the description of nine new species

Abstract

The Pseudocleobis from Chile are revised. Pseudocleobis morsicans (Gervais, 1849) and P. chilensis Roewer, 1934 are considered species inquerenda. Pseudocleobis andinus (Pocock, 1899) is removed from the Chilean fauna, and its previous records are considered misidentifications. Pseudocleobis alticola Pocock, 1900 is recorded from Chile for the first time. Nine new species are described, Pseudocleobis elongatus n. sp., P. atacamensis n. sp., P. puna n. sp., P. krausi n. sp., P. choros n. sp., P. lalackama n. sp., P. mumai n. sp., P. cekalovici n. sp. and P. escuadra n. sp. The species can be distinguished by the male chelicera morphology. We discuss the relationship of Chilean Pseudocleobis with other species of the genus, based on morphology. This work increases the number of known Chilean solifuge species by almost 70%, revealing the high degree of diversification of this group in Chile.
