Two new sympatric cave species of Castellanethes (Isopoda, Oniscidea, Olibrinidae) from Western High Atlas of Morocco

Abstract

Two new sympatric isopod species of the genus Castellanethes (Olibrinidae) are described from caves located in the Western High Atlas of Morocco. Both species present troglomorphic traits, such as the absence of body pigmentation and eyes and are, therefore, considered cave-dwelling species (troglobitic). Castellenethes ougougensis sp. nov. was found in five caves, while C. ighousi sp. nov. is an amphibious species found in only two caves, which also harbour populations of C. ougougensis sp. nov. Additionally, notes on their habitats are provided, as well as a discussion on their conservation status.
