First record of the genus Pseudocheles Chace & Brown, 1978 (Decapoda, Caridea, Pseudochelidae) from the eastern Atlantic with an analysis of the phylogenetic position of the Pseudochelidae
Abstract Four specimens belonging to the shrimp genus Pseudocheles Chace & Brown, 1978 were collected during fieldwork on São Tomé from cracks in rocks in an underwater tunnel through Santana Islet. The specimens are here described, figured and compared with the two known Atlantic species, P. chacei Kensley, 1983 from Florida and Belize, and P. falsapinca Anker, 2012 from Espirito Santo, Brazil. It is most likely that the present specimens are conspecific with P. falsapinca . The phylogenetic position of the family Pseudochelidae is reconstructed on the basis of 16S and 18S gene sequences. The family is most closely related to the Disciadidae.
