A new species of Caudotestis (Digenea: Opecoelidae) parasitizing the horsefish, Congiopodus peruvianus (Scorpaeniformes: Congiopodidae) from the Patagonian Shelf, Argentina.
J Parasitol. 2012 Dec; 98(6):1144-7.JP

Abstract

A new species of digenean, Caudotestis patagonensis n. sp. (Digenea: Opecoelidae), is described and illustrated based on specimens collected from the intestine of the horsefish, Congiopodus peruvianus (Cuvier, 1829) (Scorpaeniformes: Congiopodidae) from the Patagonian Shelf, Argentina (45-48 ° S, 60-64°W). This opecelid differs from the 4 previously known species of Caudotestis mainly in the extent of its seminal vesicle within the hindbody and the distribution of vitelline follicles. Moreover, the new species can also be distinguished by possessing the following combination of features: oral and ventral suckers nearly equal in size, ventral sucker at boundary of anterior third of body, intestinal bifurcation in posterior third of forebody and anterior to genital pore, genital pore submedial sinistral, anteriormost extent of the excretory vesicle reaching ovarian region, ovary nearly equidistant from both ventral sucker and anterior testis, posteriormost extent of the uterine loops just reaching ovarian region, testes oval and in tandem, ceca ending in front of the anterior testis, and size and number of eggs. This is the fifth recognized species of Caudotestis, the first report of a species of this genus in the southern Atlantic Ocean, and the second from a congiopodid fish.
