For the most recent diagnoses of Ctenocheles Kishinouye, 1926, see Poore et al. (2019) and Poore &amp; Ahyong (2023). Distributions and depths ranges of species are given in Table 2. Ctenocheles differs from Ctenocheloides Anker, 2010, the only other axiidean genus with elongate, pectinate cheliped fingers, by: (1) the presence of an acute, projecting rostrum; (2) the small and poorly pigmented corneas; (3) the longer fingers of the major cheliped (≥ 1.5 times the length of palm); (4) the longer and sharper teeth on the cutting edges of the major cheliped; (5) the truncate posterior margin of telson; and (6) the presence of a notch on the distal margin of the uropodal exopod (except for Ctenocheles plantei (Burukovsky, 2005)) . Besides, Ctenocheloides inhabits shallower water (less than 15 m, usually 1–1.5 m) than Ctenocheles (deeper than 10 m, up to 800 m) (Matsuzawa &amp; Hayashi 1997; Anker &amp; Pachelle 2013; Poore 2015), which might explain why it has well-developed corneas.</p></div>	https://treatment.plazi.org/id/038F87A8401F567CB5E0B27EE920FE19	Public Domain	No known copyright restrictions apply.
