  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
A new species of the Caribbean genus Cyrtopholis Simon, 1892, Cyrtopholis montserrat sp. nov. is described from the United Kingdom Overseas Territory (UKOT) of Montserrat, based on both sexes. Cyrtopholis femoralis Pocock, 1903 is redescribed from the holotype male with the first figures of the genitalia of this Montserrat endemic spider presented. The endemic Saint Barthélemy species Cyrtopholis antillana Thorell, 1894 stat. rev. is revalidated from synonymy with Cyrtopholis bartholomaei (Latreille, 1832) and non-type specimens of both sexes are described and diagnosed. Cyrtopholis innocua (Ausserer, 1871), C. intermedia (Ausserer, 1875), C. ischnoculiformis (Franganillo, 1926), and C. obsoleta (Franganillo, 1935) are proposed as nomina dubia, and Cyrtopholis respinus Franganillo, 1935 is confirmed as a nomen nudum.
