Cheilopallene Stock, 1955, one of 17 currently valid genera in Callipallenidae (Bamber et al. 2024), is characterized by lacking a palp and having a pointed tripartite lip, and a chela with a small movable finger and a truncated, nodulose immovable finger (Staples 2021). In a recent review of this genus, Staples (2015) removed three species (C. gigantea Child, 1987; C. hirta Child, 1988; and C. trappa Clark, 1971) from Cheilopallene and reassigned them as genus incertae sedis, and added one species, C. bamberi Staples, 2015. As Nakamura & Akiyama (2015) described C. ogasawarensis Nakamura & Akiyama, 2015, Cheilopallene thus currently contains six species (C. bamberi; C. brevichela Clark, 1961; C. clavigera Stock, 1955 [the type species]; C. coralliophila Müller, 1992; C. nodulosa Hong & Kim, 1987; and C. ogasawarensis), all of which have been reported from tropical to temperate regions at depths of about 30 m (Staples 2015). Two species have been reported from Japanese waters: C. nodulosa, originally described from Korea (Hong & Kim 1987), from depths of 5-42 m along the mid-southern coast of Honshu (Nakamura & Child 1991); and C. ogasawarensis from depths of 15-27 m off Hitomaru Island, Ogasawara Islands (Nakamura & Akiyama 2015). In this study, we describe a new Cheilopallene species collected from depths of 52-57 m depth in the Ryukyu Islands, southern Japan.
