Abstract

A parasitological survey searching monogeneans infesting marine fish was carried out during June 2018 and January 2020 from the coastal zone of Puerto Pizarro, Tumbes (northern Peru) and from the coastal zone of Chorrillos, Lima (central Peru). The gills, skin, nasal cavities, or branchial gill-cover of seven species were sampled. Ten monogenean species assigned to six families and nine genera were identified. The monogeneans Callorhynchocotyle callorhynchi (Manter, 1955); Capsala biparasiticum (Goto, 1894) Price, 1938; Euryhaliotrema sagmatum Kritsky & Boeger, 2002; Listrocephalos kearni Bullard, Payne &Braswell, 2004; Magniexcipula lamothei Bravo-Hollis, 1981; Nasicola klawei (Stunkard, 1962) Yamaguti, 1968; and Pseudorhabdosynochus anulus Violante-Gonzalez & Rojas-Herrera, 2011 are registered for the first time in Peru. While Capsala gregalis (Wagner & Carter, 1967) Chisholm & Whittington, 2007; Heterocotyle margaritae Chero, Cruces, Sáez, Santos & Luque, 2020; and Monocotyle luquei Chero, Cruces, Iannacone, Sanchez, Minaya, Sáez & Alvariño, 2016 have been previously registered in Peruvian waters, however, the region of Tumbes (northern Peru) represent a new locality record for these species.

Highlights

244 monogenean species have been described or reported infecting marine fish in South America
Specimens were analysed and measured using a compound OlympusTM BX51 light photomicroscope equipped with Nomarski Differential Interference Contrast (DIC) optics and drawings were made with the aid of a drawing tube
Heterocotyle margaritae is typified by its male copulatory organ, which is funnel-shaped, spatulate distally with lateral folds and by its club-shaped accessory piece (Chero et al 2020). This species is characterized by having a haptor with one central and eight peripheral loculi, 1/2/3 sinuous ridge arrangement and a vagina sclerotized. These findings extend the distribution to a new locality in northern Peru

Summary

Introduction

244 monogenean species have been described or reported infecting marine fish in South America. 96 species occur in Peru (Luque et al 2016a, 2016b). Peru has a rich fauna of marine fish with approximately 1070 species, including Chondrichthyans and teleosts, distributed in 549 genera, 194 families and 39 orders Este artículo es publicado por la Revista Peruana de Biología de la Facultad de Ciencias Biológicas, Universidad Nacional Mayor de San Marcos.
