ABSTRACT
Neoheterobothrium papillosum n. sp. (Monogenea Diclidophoridae) is described based on specimens collected from the gills of the dusky flounder Syacium papillosum (Linnaeus) (Paralichthyidae) in the Yucatan Shelf. The new species can be differentiated from other congeneric species by the following characteristics (1) number of hooks in the genital atrium (8 hooks), (2) number of testes (20-34), (3) pharynx size, (4) peduncle length, and (5) egg size. Neoheterobothrium papillosum n. sp. resembles Neoheterobothrium syacii; however, detailed morphological analysis allowed for their separation into two different species. Sequences of the nuclear ribosomal DNA partial 28S and ITS1 were obtained and compared with available sequences of other species and genera of the family Diclidophoridae from GenBank. A phylogenetic analysis was conducted, including 33 sequences, 18 of which represented 17 species and 11 genera of the family Diclidophoridae. The phylogenetic tree showed that Diclidophoridae is a monophyletic family and species of Diclidophora were grouped as the sister group of Neoheterobothrium papillosum n. sp. Our phylogenetic analyses were consistent with Mamaev's hypothesis, who divided Diclidophoridae into Diclidophorinae and Choricotylinae and concluded that Neoheterobothrium was a genus belonging to Diclidophorinae.
