Kroyeria brasiliense sp. nov. (Copepoda, Kroyeriidae)a gill parasite of the shark, Galeorhinus vitaminicus de Buen, in Rio Grande do Sul State, Brazil

Abstract

Kroyeria brasiliense sp. nov. from the shark, Galeorhinus vitaminicus de Buen, 1950, from Rio Grande do Sul, State, Brazil, is described on the basis of 14 adult females. The new species is superficially similar to Kroyeria deetsi Dippenaar, Benz & Olivier, 2000, but differs from it in the following characters. The maxillipeds of the new species are large and project well beyond the lateral margins of the cephalothorax. Those of K. deetsi are much smaller. The third endopodal segments of K. deetsi are twice as long as the second endopodal segments and are provided with prominent marginal denticles. The second and third endopodal segments of the new species are rounded, of similar length and lack teeth.

“…A detailed review of Kroyeria species, their distinctive features, reported hosts and their geographical locations is described [13,16,10,11] (Table 1). The species described in the present paper was identified as Kroyeria minuta because it showed the distinctiveness described by Pillai (1968) in the original description.…”

“…Most of the parasitic crustaceans belong to Isopoda, Branchiura and Copepoda [1][2][3][4][5][6]. The genus Kroyeria (Copepoda: Eudactylinidae) is the largest of the three genera of the family Kroyeriidae with 21 nominal species infecting the about 200 species of ground sharks [7][8][9][10][11][12]. Most Kroyeria species are host specific on carcharhiniform sharks of the families Carcharhinidae and Triakidae with a few species having been reported from the family Sphyrnidae [13,14].…”
