Two new genera of crinoid-associated pontoniine shrimps, Brucecaris, new genus, and Unguicaris, new genus, are described and illustrated. Brucecaris is established for Periclimenes tenuis Bruce. Unguicaris panglaonis, new genus, new species, is described from crinoid-associated material collected at Panglao Island, Bohol Sea, The Philippines. Three species, Periclimenes alegrias Bruce, Periclimenes novacaledoniae Bruce and Periclimenes pilipes Bruce and Zmarzly, are transferred to Unguicaris since they significantly differ from the diagnosis of the type species of the genus Periclimenes Costa, P. amethysteus (Risso). Remarks on systematic positions of remaining crinoid-associated species of the genus Periclimenes are given.
