Abstract

Abstract The family Bopyridae Rafinesque, 1815 is comprised of parasitic isopods with a life cycle involving an intermediate host (copepod) and a definitive host (decapod crustacean). The genus Anuropodione Bourdon, 1967 occurs in all oceans and encompasses five species that are only known as parasites of squat lobsters belonging to the genus Munida Leach, 1820. Despite the broad distribution of the genus, no species has ever been recorded from the South Atlantic. A total of 416 specimens of Munida iris A. Milne-Edwards, 1880 were collected in Potiguar Basin around the isobaths of 400 m, including 24 individuals (5.77%) containing parasites within their branchial chambers. Male parasites showed considerable variability in the number of pleomeres, with many showing four pleomeres, a number previously unknown for males of any species in the genus. These specimens represent the first occurrence of the genus Anuropodione and the species A. carolinensisMarkham, 1974 from the South Atlantic (Brazilian waters).

Highlights

The isopod family Bopyridae Rafinesque, 1815 contains species that are parasites of calanoid copepods as their intermediate hosts and decapod crustaceans as their definitive hosts
Species of Anuropodione have only been recorded as parasites of squat lobsters, especially those belonging to the genus Munida (Williams and Brown, 1972; Markham, 1974; Wenner and Windsor, 1979); the host of A. dubius is not certain as it was given as “Galathea spec.” by Nierstrasz and Brender à Brandis (1929)
In this paper we report the first occurrence of the genus Anuropodione and the species A. carolinensis Markham, 1974 collected as a parasite of the squat lobsters M. iris A

Summary

Introduction

The isopod family Bopyridae Rafinesque, 1815 contains species that are parasites of calanoid copepods as their intermediate hosts and decapod crustaceans as their definitive hosts. The genus Anuropodione Bourdon, 1967 has a widespread distribution, occurring in all oceans, especially in relatively deep waters around 200–700 m (Williams and Brown, 1972; Wenner and Windsor, 1979), and is composed of five species: A. amphiandra (Codreanu, Codreanu and Pike, 1966), A. carolinensis Markham, 1974, A. dubius (Nierstrasz and Brender à Brandis, 1929), A. megacephalon Markham, 1974 and A. senegalensis Bourdon, 1967 (Boyko et al, 2008 onwards).
