  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.

Different, but still the same: integrative taxonomy confirms a new species of Eresus Walckenaer, 1805 (Araneae, Eresidae) from the South Caucasus

Abstract

This study represents the first step toward a systematic revision of the velvet spider genus Eresus Walckenaer, 1805 in the Caucasus. Here, Eresus transcaucasicus sp. nov. is described using an integrative approach, based on male specimens collected from the South Caucasus. The species was previously reported as E. kollari Rossi, 1846 from Armenia and as Eresus sp. from Georgia. Intraspecific variations in both coloration patterns and conductor shape, which have been rarely documented in this genus, are illustrated. The validity of previous records of E. kollari in the region is discussed.
