  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.

We have two of them: A review of the genus Mastigusa (Araneae: Cybaeidae) in Bulgaria

Abstract

In the present study, we review the status of the genus Mastigusa Menge, 1854 in Bulgaria. We identified two species from the country, namely M. arietina (Thorell, 1871) and M. macrophthalma (Kulczyński, 1897). This is the first record of M. arietina from Bulgaria. Furthermore, we report a male palpal polymorphism in M. arietina in the populations around the Black Sea. We also provide molecular support for our conclusions, combining newly generated DNA sequences with information available in GenBank.
