  New locality records and future habitat suitability of Sassanidotus gracilis (Birula, 1900) (Scorpiones: Buthidae) in the Iran–Afghanistan–Pakistan arid belt Abstract This study reports new locality records from Iran and a climate-based habitat suitability assessment for Sassanidotus gracilis (Birula, 1900) (Scorpiones: Buthidae) in the Iran–Afghanistan–Pakistan arid belt. We document new specimens from Sistan and Baluchestan Province, Iran, with an updated distribution map and illustrations, and we model the species' potential distribution across south-eastern Iran and adjacent parts of Afghanistan and Pakistan. Habitat suitability was associated mainly with precipitation seasonality, precipitation of the wettest month, precipitation of the driest month, and slope. In an arid setting these rainfall variables are unlikely to indicate a need for moist habitat; they more plausibly track seasonal productivity and the terrain features that provide shelter. Present-day suitable areas...

New species and first record of the genus Titanidiops Simon, 1903 from Sudan (Araneae: Idiopidae) 

Abstract 

A new species of Titanidiops Simon, 1903 is described from Sudan, Titanidiops logunovi sp. nov. based on a holotype male from Galegu in the south of the country. It differs from other known congeners and the many African species currently misplaced in Idiops Perty, 1833 based on a combination of palpal bulb, tibial, and sternal morphology.
