Cheramus Bate, 1888

Cheramus Bate, 1888: 29 .— Poore et al., 2019: 93 (rediagnosis, synonymy).— Poore and Ahyong, 2023: 212 .

Remarks. The type species of Cheramus was selected by Manning and Felder (1991) as Cheramus occidentalis Bate, 1888 , now C. profundus (Biffar, 1973) . As Sakai (2005) pointed out, this subsequent type species designation predated by one day that by Holthuis (1991) of Cheramus orientalis Bate, 1888 . Cheramus profundus is a West Atlantic species and the only member of the genus ( Poore et al., 2019). Lacking molecular data, Robles et al. (2020) and Poore et al. (2019) relied on morphology to place the genus close to Cheramoides Sakai, 2011 and Poti Rodrigues and Manning, 1992 , two other monotypic West Atlantic genera. The antennular peduncle is exceeded by all of the antennal peduncular article 5 and the minor and major chelipeds are similar, both attenuated, with swollen palms (Biffar, 1973). Cheramus has been widely used as a genus or subgenus name for small callianassids in the Indo-West Pacific. Sakai (2011) included 16 species and others have been added since (Komai and Fujiwara, 2012; Komai et al., 2014b; Sepahvand et al., 2015). Komai et al. (2014b) reviewed use of the genus name but Cheramus does not occur in the Indo-West Pacific.
