  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

The new synanthropic crevice weaver spider species, from the family Filistatidae, Pikelinia floydmuraria sp. nov. (male and females) is described from the department of Tolima, Colombia. The female internal genitalia of P. fasciata from the Galapagos islands, Ecuador, is described here for the first time. Additional unidentified species of Pikelinia populations were recorded in the departments of Cauca, Quindío, and Risaralda. Dietary analysis of P. floydmuraria sp. nov. (Tolima) and Pikelinia sp. (Armenia) revealed a predominance of Hymenoptera (~35% of prey), followed by Diptera and Coleoptera. This study expands known diversity and trophic ecology of Pikelinia genus.
