  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.

Two new species of the genus Cladothela (Araneae: Gnaphosidae) from Nansei Islands, southwest Japan, with the description of the true female of C. auster

Abstract
Examinations of spiders of the gnaphosid genus Cladothela collected from Nansei Islands, Japan revealed that two undescribed species of the genus occur in the area, and that in C. auster Kamura 1997, the previous understanding of the combination of male and female is incorrect. Two new species, Cladothela notus n. sp. and C. sakishima n. sp., and the true female of C. auster are described.
