  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.

Annotated checklist of the spiders of Ascension Island with new faunistic records, including three newly recorded non-native species (Araneae: Araneomorphae)

Abstract
A checklist of the spiders of Ascension Island is given, with new faunistic records for one family, five genera, and three species-level taxa. For the latter, Oecobius marathaus Tikader, 1962 (Oecobiidae), and Scytodes velutina Heineken & Lowe, 1832 and S. univittata Simon, 1882 (both Scytodidae) are recorded. Seven genera recorded from the island by prior workers based on indeterminable immature material are expunged from the list due to lack of evidence. In total, 38 genera and 41 species, accommodated in 22 families, are recognised as valid taxa on Ascension. Of these, only 1 genus and 5 species are considered possibly or probably endemic, meaning 99.97% of genera and 87.81% of species are non-endemic.
