Spirocamallanus papillicaudatus n. sp. from Pomadactylus oligodon, S. partitus n.sp. from Pomacentrus partitus, S. spinicaudatus n. sp. from Holocentrus marinus and S. garnotus n.sp. from Halichoeres garnoti are described from marine fishes of Puerto Rico which is recorded as a new geographical locality for the genus Spirocamallanus. S. plumierus n.sp. is described from a marine fish, Diapterus plumieri, of the Golfo de Cariaco, Cumana, Venezuela. These new species are distinguished from the known species mainly on the basis of number and arrangement of caudal papillae and different body measurements.
