  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.

The spider genus Tutaibo (Araneae, Linyphiidae) in Uruguay: two new species and new records

Abstract

Tutaibo carita Cajade sp. nov. and Tutaibo sam Cajade sp. nov. are described from Uruguay based on males and females. Illustrations of somatic and sexual characters and a species distribution map are provided. In addition, new records of Tutaibo velox (Keyserling, 1886) are provided. These findings represent the southernmost records for Tutaibo and constitute the first report of the genus for Uruguay.
