  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.

A new species of Vitalius (Araneae: Theraphosidae) from the Brazilian Cerrado

Abstract

A new theraphosid species, Vitalius ornatissimus sp. nov., is described based on one male and one female from Brazil. The new species is distributed in the Brazilian states of Tocantins, Goiás, Distrito Federal, and the western state of Bahia, living in areas of the Cerrado biome. It is closely related to and resembles Vitalius chromatus (Schmidt, 2004) in appearance, with a general black coloration and whitish rings or stripes on the legs and palp in both sexes. With V. chromatus, it shares the presence of a row of spines on the distal-retrolateral edge of palpal tibia of male, but differs by the tibial apophysis and metatarsus I shape. Vitalius ornatissimus sp. nov. is the first species of Vitalius Lucas, Silva Jr & Bertani recorded exclusively in central Cerrado.
