  Cicileus derradji sp. nov., a new species from southern Algeria (Scorpiones: Buthidae) Abstract A new scorpion species, Cicileus derradji sp. nov., is described from Tin Zaouatine District, In Guezzam Province, southern Algeria. The description is based on an adult male holotype, an adult female paratype and a juvenile specimen, and is supported by detailed morphological analyses, including colouration, morphometrics, carination patterns and trichobothrial arrangement. This discovery extends the known distribution of the genus Cicileus approximately 500 km southwestward within Algeria. With the addition of this species, the number of recognised species in the genus increases to six. The new species is compared with all previously known species of Cicileus , and detailed colour photographs, including images taken under ultraviolet illumination, are provided.

Abstract


I report the first documented case of the buthid scorpion Aegaeobuthus nigrocinctus (Ehrenberg, 1828) serving as prey for the tarantula Chaetopelma olivaceum (C. L. Koch, 1841) in Lebanon. The observation was made during a nocturnal survey in the Mount Lebanon region. The case contributes to the limited records of tarantula predation on scorpions and underscores the role of prey-predator size asymmetry in facilitating high-risk predation among arachnids.
