Taxonomic Status of Neoechinorhynchus Agilis (Acanthocephala, Neoechinorhynchidae), with a Description of two New Species of the Genus from the Atlantic and Pacific Mullets (Teleostei, Mugilidae)

Abstract

Taxonomic Status of

Helminth species richness of introduced and native grey mullets (Teleostei: Mugilidae)

“…But at a large scale, due to coastal nature of mullets, vicariance may explain the occurrence of a large portion of parasite species as, for example, in such widely distributed M. cephalus [43]. Current literature data of Dmitrieva et al [50], Sarabeev et al [17] and the present observations indicate that among the helminth fauna parasitizing this fish only one dactylogyrid monogeneans, Ligophorus chabaudi, was reported in both regions, while all other species of monogeneans, digeneans, acanthocephalans and nematodes occur only in the Mediterranean or in the Sea of Japan ( [8][9][10][11][12][13][14][15]17,18,33], the present study).…”

“…Identification of some metacercariae was done to genus or even family level (see Appendix A) due to the paucity of morphological features useful for the identification of larval stages and specific requirements for mounting and examination of specimens [20,30]. Identification of monogeneans followed Euzet and Combes [31] and Sarabeev et al [17], acanthocephalans followed Tkach et al [18] and nematodes followed Belous [32] and Orecchia and Paggi [33].…”

“…Helminth fauna of these fish in the northeast Atlantic and in the Sea of Japan is well known [7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Based on an extensive search of the literature and the Host-Parasite Database [19] Kostadinova [20] compiled the checklist of the metazoan parasites of L. haematocheilus throughout its distributional range that comprised 69 nominal species of helminth and ectoparasitic crustacean parasites on that time.…”

Histopathological and ultrastructural assessment of two mugilid species infected with myxozoans and helminths

“…The acanthocephalan N. agilis is a widely spread parasite of grey mullets in the Atlantic and Pacific Oceans (Tkach, Sarabeev, & Shvetsova, ). This study showed that N. agilis penetrates with the proboscis in mucosal and submucosal layers and most likely induce an intense response of mucosal immunity in L. saliens and L. ramada (Table ).…”

Molecular data confirm the species status of Neoechinorhynchus personatus and N. yamagutii (Acanthocephala, Neoechinorhynchidae) from the Atlantic and Pacific grey mullets (Teleostei, Mugilidae)

“…Th e taxonomic status of Neoechinorhynchus agilis s. l. (Rudolphi, 1819) from grey mullets (Mugilidae) across localities in the North-East Atlantic and the North-West Pacifi c areas was recently reviewed by Tkach et al (2014). Th is taxonomic review performed on morphological features showed that there were three diff erent species of Neoechinorhynchus occurring in mullet hosts, two of those were recorded in the Atlantic and one in the Pacifi c waters (Neoechinorhynchus (Neoechinorhynchus) agilis (Rudolphi, 1819) and Neoechinorhynchus (Hebesoma) personatus Tkach, Sarabeev et Shvetsova, 2014, Neoechinorhynchus (Hebesoma) yamagutii Tkach, Sarabeev et Shvetsova, 2014, respectively).…”
