摘要

描述了一新种,1892年(粘孢子目:双valvalvulida:粘虫科)侵染秘鲁瓦朗西涅(valcienes, 1833)的胃内区域(Centrarchiformes: Latridae),秘鲁手工渔业中的一种重要经济鱼类。在形态学上,Henneguya chirodactyli n. sp.不同于其所有同系物,这是由于粘孢子尺寸、极性丝圈数和孢子体外部包膜的结合。基于18S rRNA基因序列的系统发育分析表明,该新种是H. lagunensis de Azevedo, Negrelli, de Oliveira, Abdallah, Camara, Matos和Vieira, 2021的姊妹种。此外,该物种位于由12种Henneguya和1种Myxobolus b tschli, 1882组成的分支中,所有这些都感染海鱼。我们强调,这是首次采用综合方法进行的研究,包括形态学(外部),扫描电子显微镜(SEM)和来自秘鲁海洋环境的Henneguya物种的分子描述。

Morphological and molecular characterization of Henneguya chirodactyli n. sp. (Cnidaria: Myxosporea), a parasite of the Peruvian morwong Chirodactylus variegatus (Valenciennes, 1833) (Centrarchiformes: Latridae)

Morphological and molecular characterization of Henneguya chirodactyli n. sp. (Cnidaria: Myxosporea), a parasite of the Peruvian morwong Chirodactylus variegatus (Valenciennes, 1833) (Centrarchiformes: Latridae)
A new species of Henneguya Thélohan, 1892 (Myxosporea: Bivalvulida: Myxobolidae) infecting the internal region of the stomach of the Peruvian morwong Chirodactylus variegatus (Valenciennes, 1833) (Centrarchiformes: Latridae), an economically important fish in Peruvian artisanal fishery, is described. Morphologically, Henneguya chirodactyli n. sp. differs from all its congeners due to the combination of myxospore dimensions, polar filament coil count, and an external envelope in the spore body. Phylogenetic analysis based on 18S rRNA gene sequences places this new species as sister to H. lagunensis de Azevedo, Negrelli, de Oliveira, Abdallah, Camara, Matos and Vieira, 2021. Furthermore, this species is located in a clade composed of 12 species of Henneguya and one of Myxobolus Bütschli, 1882, all of which infect marine fish. We emphasize that this is the first study performed with an integrative approach, including morphological (external), scanning electron microscopy (SEM) and molecular descriptions, of a Henneguya species from a Peruvian marine environment.
