  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...

A new species of Euathlus (Araneae: Theraphosidae) from northern Chile, with morphological novelties for the genus 

Abstract 

A new species of Euathlus Ausserer 1875 is described from the Coquimbo Region, Chile. Euathlus sinapophysis sp. nov. is differentiated from its congeners by the presence of an oval patch of setae on the ventral surface of the abdomen and the absence of a tibial apophysis on the first leg of males. Both morphological characteristics are reported for the first time for the genus.
