  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.

Urupelma humantay, a new species of Andean tarantula from the Cuzco region in Peru (Araneae: Theraphosidae: Theraphosinae)

Abstract

A new Peruvian tarantula, Urupelma humantay sp. nov., from the Cuzco region is herein described, diagnosed and illustrated. The species is similar to Urupelma veronicae Kaderka et al., 2023, and U. dianae Kaderka et al., 2023, another two Andean tarantulas from the Cuzco region; it differs trom these two species in the absence of retrolateral keel in the morphology of palpal bulb, and in the different shape of seminal receptacles without sclerotized basal extensions.
