  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.

On the spider family Dolomedidae Simon, 1876 in India and Sri Lanka (Arachnida: Araneae)

Abstract


We report the first record of the spider family Dolomedidae Simon, 1876, and the genus Dolomedes Latreille, 1804 from India, including the first record, and a redescription of the widely distributed species, Dolomedes mizhoanus Kishida, 1936. We also review the two Dolomedes species previously known from Sri Lanka, and discuss the record of Dolomedes boiei (Doleschall, 1859) in Sri Lanka. We provide detailed descriptions and genitalic illustrations of Dolomedes karschi Strand, 1913 and D. mizhoanus, with a distribution map of the family in India and Sri Lanka. We also propose D. boiei to be treated as a nomen dubium due to its unknown type deposition and vague original description.
