Cladothela boninensis Kishida, 1928 . Holotype from Ogasawara Islands (type specimen lost). Remarks. Currently, 11 species are known in this genus in East Asia ( World Spider Catalog 2022 ). This genus can be distinguished from other gnaphosids by the presence of a conspicuous, hook-like, retrolateral sclerotized spine on the male palpal femur ( Kamura 1999 ). Three Cladothela species have been recorded in the Ryukyu Islands, namely: C. auster Kamura, 1997 ; C. parva Kamura, 1991 ; C. oculinotata (Bösenberg and Strand, 1906) ( Shimojana 1977 , 1981 ; Kamura 1991 , 1997 ; Tanikawa and Sasaki 1999 ).
