Cicileus derradji sp. nov., a new species from southern Algeria (Scorpiones: Buthidae)

  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.

Preliminary survey of midget cave spiders (Araneae, Leptonetidae) from forest ecosystems in southern China with the description of three new species

Abstract

This study reports six leptonetid species from three genera collected in karst-associated forest ecosystems of southern China. Three new midget cave spider species are diagnosed, described, and illustrated: Pararana jiufushanensis Yao & K. K. Liu, sp. nov. (♂, ♀; Fujian Province), P. songyuani Yao & K. K. Liu, sp. nov. (♂; Guangdong Province), and Leptonetela zhaoruii Yao & K. K. Liu, sp. nov. (♂, ♀; Fujian Province). Notably, the female of P. gaofani Lin & Li, 2022 is described for the first time, while the holotype of P. mingxuani Yao & Liu, 2024 is illustrated with detailed images of the male palpal characters. Additionally, Rhyssoleptoneta lishan Tong, 2024 is newly recorded in Jiangsu Province, expanding its known geographic range. Detailed distribution records are provided for all species, emphasizing southeastern China’s significance as a hotspot for leptonetid diversity and adaptive radiation. These findings refine taxonomic frameworks for karst-associated spiders and enhance understanding of their biogeographic patterns in East Asian karst systems.
