  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 Trapdoor Spider (Araneae: Idiopidae: Heligmomerus) from the Southern Tip of India

Abstract

A new species of the genus Heligmomerus is described based on 10 female specimens collected from
the foothills of Pothaimalai, on the outskirts of the Kalakad-Mundanthurai Tiger Reserve, Tirunelveli
District, Tamil Nadu, India. The new species is distinguished from all other Indian and Sri Lankan
congeners in combination with several non-overlapping morphological characters. Detailed natural
history of the new species, intraspecific variation in spermathecal morphology, and meristic and
mensural data from the type series are given. Additionally, comments on the transfer of Idiops
garoensis (Tikader, 1977) to the genus Heligmomerus by Sen et al. (2012) are provided.
