A new Hemiscorpius Peters, 1861 (Scorpiones: Hemiscorpiidae) from southwestern Iran

A new Hemiscorpius species, H. kashkayi sp. nov., is described from the Khuzestan and Ahwaz region in southwestern Iran. H. kashkayi is related to H. persicus Birula, 1903, known from Baluchestan in eastern Iran, which does not show sexual dimorphism between males and females, like H. kashkayi. These 2 species differ from all other Iranian Hemiscorpiidae species in having no sexual dimorphism. H. kashkayi is distinguished from H. persicus by its relatively short and well-developed stout metasoma and pedipalp segments, less developed patellar process, and carapacial and mesosomal carination.
