  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

New data on agelenid spiders of the Balkans are provided. A new species of the genus Eratigena Bolzern, Burckhardt & Hänggi, 2013, Eratigena mirusha sp. nov. (♂/♀) from the Koznik Mountain in Kosovo is described, based on molecular and morphological data. The males Eratigena mirusha sp. nov. are most similar to E. agrestis (Walckenaer) but possess differently shaped conductor and retrolateral tibial apophysis. Females of both species differ in the shape of the epigyne and the posterior sclerite and from the positions of the copulatory openings, and the epigynal pseudo teeth. The genetic divergence calculated based on the barcode region of the cytochrome c oxidase subunit I gene (COI) confirms the morphological distinctness and supports Eratigena mirusha sp. nov. as a sister species of E. agrestis.
