A new species of the genus Scorpiops Peters, 1861, subgenus Euscorpiops Vachon, 1980 from Thailand (Scorpiones, Scorpiopidae).

A new species, Scorpiops (Euscorpiops) krachan sp. nov. , belonging to the family Scorpiopidae Kraepelin, 1905 is described based on three adult males and one adult female collected in the Kaeng Krachan National Park, Phetchaburi Province, Thailand. The new species presents most features exhibited by scorpions of the subgenus Euscorpiops and can be characterized notably by a very small size, a sexual dimorphism strongly marked with male pedipalps elongated, a distinct trichobothrial pattern and other morphological features. This new taxon may represent one endemic element for the scorpion fauna of Thailand. Aspects of the ecology and distribution of the new species are discussed and compared with that of other relative Scorpiops species.
