A new species of Neoheterobothrium Price, 1943 (Monogenea, Diclidophoridae) from Syacium papillosum (Linnaeus) (Pleuronectiformes, Paralichthyidae) in the Yucatan Shelf, with notes on the validity of the subfamilies in the Diclidophoridae

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.

1943年从尤卡坦州架子上的Syacium papillosum(Linnaeus)(Pleuronectiformes,Paralichthyidae)购得的一种新的新异戊二烯价格(Monogenea,Diclidophoridae),并记述了Diclidophoridae中亚科的有效性

Neoheterobothrium疣ñ。sp。(Monogenea:Diclidophoridae)是根据从尤卡坦州架子上阴暗比目鱼Syacium papillosum(Linnaeus)(Paralichthyidae)collected的标本中描述的。可以通过以下特征将新物种与其他同类物种区分开:(1)生殖器心房中的钩子数量(8个钩子),(2)睾丸的数量(20-34),(3)咽部大小,(4 )花梗长度,以及(5)鸡蛋大小。Neoheterobothrium疣ñ。sp。类似于新异病杆菌; 但是,详细的形态分析允许将它们分为两个不同的物种。获得了核糖体DNA部分28S和ITS1的序列,并将其与GenBank中双斜科的其他物种和属的可用序列进行了比较。进行了系统发育分析,包括33个序列,其中18个代表双翅目科的17种和11属。进化树显示,Diclidophoridae是一个单家庭和物种Diclidophora被归为姊妹群的Neoheterobothrium疣ñ。sp。我们的系统发育分析均采用Mamaev的假设,谁分Diclidophoridae成Diclidophorinae和Choricotylinae一致,得出的结论是Neoheterobothrium 是双斜孢属的属。
