Bravo-Hollis, 1981

Anchoromicrocotylinae is a subfamily within family Microcotylidae and class Monogenea. This subfamily was created by Bravo-Hollis in 1981, to accommodate Monogeneans recovered from the gills of Atractoscion nobilis (Sciaenidae) (synonym of Cynoscion nobilis ) caught off California. In the same work, Bravo-Hollis in 1981 created the new genus Anchoromicrocotyle and amended the diagnosis of the family Microcotylidae. [1] Members of Anchoromicrocotylinae differ from other Microcotylidae by the presence of a larval organ and larval hooks and the structure of the genital complex. [1]

Morphology

Members of Anchoromicrocotylinae are characterized by a symmetric haptor, with a sharp end that bears three pairs of larval hooks. The digestive system includes two oral suckers with papillary borders, a pharynx and an esophagus. The male genital system includes numerous testes located behind the ovary (post-ovarian testes), a vas deferens and a complex male copulatory organ, composed of: a male atrium, a penis, and a prostate vesicle. The female genital system include a complex ovary, a genito-intestinal canal, an ootype, a uterus, and a single dorsal unarmed vagina. [1]

Species

According to the World Register of Marine Species, [2] there are two genera in this subfamily:

Anchoromicrocotyle is a genus which belongs to the family Microcotylidae and class Monogenea. Species of Anchoromicrocotyle are ectoparasites that affect their host by attaching themselves as larvae on the gills of the fish and grow into adult stage. This larval stage is called oncomiracidium, and is characterized as free swimming and ciliated. As all Anchoromicrocotylinae, members of Anchoromicrocotyle are characterized by a larval organ and larval hooks and the structure of their genital complex. This genus was created by Bravo-Hollis in 1981, to accommodate Monogeneans recovered from the gills of Atractoscion nobilis (Sciaenidae) caught off California. In the same work, Bravo-Hollis in 1981 created a new subfamily Anchoromicrocotylinae and emended the diagnosis of the family Microcotylidae.
