 en Monogeneans of Leatherjackets, Oligoplites spp. (Osteichthyes: Carangidae), with the Description of a New Species of Metacamopia (Monogenea: Allodiscocotylidae) from the Coast of the State of Rio de Janeiro, Brazil
Ricardo M Takemoto; Jfr Amato & Jose Luis Luque

Abstract

Metacamopia oligoplites n. sp., a gill filament parasite of
carangid fishes of three species of Oligoplites Gill,
O. palometa (Cuvier), O. saurus (Bloch & Schneider), and O.
saliens (Bloch), from the coast of the State of Rio de
Janeiro, Brazil, is  described and illustrated. Metacamopia
oligoplites n. sp. differs from M. indica by: the shape of the
body; the pre-, para-, and post-germarial testes; vaginas
lacking sclerotized structures; well-developed seminal
receptacles; muscular sleeves around the constriction between
the vaginas and the seminal receptacles; and the haptor highly
asymmetric, with a large, heel-like area; and differs from M.
chorinemi by: the esophagus lacking diverticles;  a larger
number of testes (26-55) and not just, approximately 10; and
the vaginas lacking sclerotized structures of any kind. This
is the first record of  Metacamopia in the South Atlantic
Ocean. The generic diagnosis of Metacamopia is emended.
Hargicola oligoplites is reported for the first time in the
South Atlantic Ocean. Oligoplites palometa and O. saliens are
new host records for Hargicola oligoplites.
