This genus Ancylomenes is polyphyletic (see Horká et al . 2016 : fig. 2; Chow et al . 2021 : fig. 2). A. pedersoni is closely related to two Caribbean anemone associated species of Periclimenes , P. rathbunae and P. yucatanicus . Its final taxonomic placements await the revision of the genus Periclimenes . FIGURE 2 . Ancylomenes pedersoni ( Chace, 1958 ) .

(Photographs by C.H.J.M. Fransen.). Ecology . Associated with sea anemones Actinia bermudensis (McMurrich, 1889) , Exaiptasia diaphana (Rapp, 1829) , Bartholomea annulata , Bunodosoma granuliferum (Le Sueur, 1817) , Cerianthus sp. , Condylactis gigantea , Laviactis lucida , Lebrunia neglecta ( Silbiger & Childress 2008 ; Brooker et al. 2019 ). Occasionally found on the black coral Plumapathes pennacea (Pallas, 1766) (Spotte 1995, as Antipathes pennacea ), the jellyfish Cassiopea xamachana Bigelow, 1892 ( Criales 1984 ), the corallimorpharians Ricordea florida Duchassaing & Michelotti, 1860 and Rhodactis osculifera (Le Sueur, 1817) (as Discosoma ( Rhodactis ) sanctithomae (Duchassiang & Michelotti, 1860)) ( Williams & Williams 2000 ) and the bivalve mollusk Ctenoides scaber (Born, 1778) (Spotte 1995) . Known as fish cleaner ( Brinkmann & Fransen 2016 ; De Grave & Anker 2017 ; Horká et al. 2018 ). Here recorded from algae Lobophora variegata , probably due to the retraction of a host sea anemone. Distribution . Widely distributed in shallow waters of the tropical and subtropical western Atlantic from North Carolina to Espiritu Santo, Brazil , in depths between 1 and 40 m ( De Grave & Anker 2017 ).
