“…1 localities 2–3–4). Intrinsic differences, such as those relating to host-parasite life history characteristics, will readily influence a species that can expand its range or invade new habitats [14]. Future studies are needed to investigate the influence of life history characteristics on the establishment of this parasite-host association.…”

Triloculotrema euzeti n. sp. (Monogenea, Monocotylidae, Merizocotylinae) is described from the nasal tissues of the blackspotted smooth-hound Mustelus punctulatus collected from the coastal marine waters off Tunisia. The new parasite species is distinguished from the other two species of the genus, T. japanicae Kearn, 1993 and T. chisholmae Justine, 2009, by the morphology of the sclerotised male copulatory organ which has longitudinal ridges. The species is also characterised by its oötype with short descending and ascending limbs (long and more convoluted in the other two species). The presence of three peripheral loculi, which is the main characteristic of the genus Triloculotrema Kearn, 1993, is unconfirmed. This is the first description of a species of this genus in the Mediterranean Sea and the first record from a coastal shark.

“…Therefore, the true range of hosts and their parasites may not be adequately represented (Burger and Adlard, 2011). Low parasite prevalence and intensity may also obscure the true host range, and inaccurate host-parasite identification will further add to the problem (Glennon et al, 2008;Poulin and Morand, 2000). Cribb et al (2001) reviewed the association among digeneans, molluscs and fishes and highlighted that all the available data to be analysed are biased in the way it has been collected.…”

“…However, whether such large-scale changes also affect population divergence and speciation rates in marine parasites has yet to be thoroughly tested. Additional difficulties concern cryptic microgeographic population structures, that is, cryptic parasite subgroups within a host (Criscione et al, 2011;Glennon et al, 2008). For example, a recent study on the relatedness in the Kudoidae pointed out that relationships are rather reflected by the site of infection within the host rather than host identity per se (Burger et al, 2007); therefore, the presence of one or more parasitic lineages on the same host can result in divergent host and parasite phylogenies (Criscione et al, 2011;Page, 1993).…”

“…Monogenea (Platyhelminthes) is a group of obligatory and monoxenic parasites that infest vertebrates, mainly fishes. Although monogeneans have been considered to exhibit strict host specificity in the past (Bychowsky 1957;Llewellyn 1982), different ranges of host specificity have been reported for the group, challenging their status as 'evolutionary host mirrors' (Klassen & Beverley-Burton 1987;Boeger & Kristky 1997;Desdevises et al 2000Desdevises et al , 2002Chisholm et al 2001a;Sinnappah et al 2001;Boeger et al 2005;Glennon et al 2008;Plaisance et al 2008;Verneau et al 2009;.…”

Molecular phylogeny of Potamotrygonocotyle (Monogenea, Monocotylidae) challenges the validity of some of its species. -Zoologica Scripta, 40, 638-658. The marine-derived stingrays Potamotrygonidae are the only chondrichthyans landlocked to freshwaters of Central and South America. The family includes approximately 22 described species organized in four genera widely distributed across the main Atlantic and Caribbean continental drainages. Investigations into the parasite fauna of potamotrygonids have mainly focused on cestodes, with a few studies addressing the biodiversity of monogeneans. Potamotrygonocotyle (Monogenea, Monocotylidae) is composed of 12 species, exclusively found in the gills of species of Potamotrygonidae.This study presents molecular phylogenetic analyses of this group of monogeneans distributed throughout La Plata and Amazonas basins, with the purpose of readdressing the phylogeny of Monocotylidae based on 28S rDNA sequences and of unravelling the phylogeny of its species using data from mitochondrial gene cytochrome c oxidase subunit I and nuclear gene internal transcribed spacer 1. The phylogenetic status of the five tested monocotylid subfamilies and most of their internal relationships are concordant with the results of a previous study, and the monophyletic status of Potamotrygonocotyle based on molecular data is corroborated for the first time. However, the placement of the genus within Monocotylidae is not resolved, as its sister-group relationship with Neoheterocotyle and Troglocephalus is uncertain. Investigations into the relationships within Potamotrygonocotyle support the monophyletic status of nine nominal species and suggest the existence of cryptic lineages for the remaining three. Molecular analyses reveal distinct sister-groups relationships in comparison with a previously published phylogeny for the genus based on morphological data. Finally, the surveys of this study expand the known distribution range of some members of Potamotrygonocotyle.
