“…However, the character of these spines is different in different species. The tail tip of D. alatae, D. mexicanus and D. rasheedae is nondivided, all covered by very numerous minute spines, whereas that of D. hartwichi is nondivided, bearing a ring of few spines at its base (De and Maity 1995;Gibbons and Saayman 1996;Caspeta-Mandujano et al 1999;Moravec et al 1999Moravec et al , 2011; a similar ring of spines at base of the tail tip is also present in D. spinicaudatus, but the tail tip terminates in four spikes (Timi et al 1997); the tail tip of D. longispiculatus terminates in a tricuspidated process (Wang and Lin 1975).…”

Recent parasitological examinations of the marine perciform fish (tigerteeth croaker) Otolithes ruber (Bloch et Schneider) (Sciaenidae) from off Iran yielded one new and one previously known nematode species: Dichelyne (Dichelyne) spinigerus sp. nov. (Cucullanidae) from the host’s intestine in the Persian Gulf and Philometra otolithi Moravec et Manoharan, 2013 (Philometridae) from the ovary in the Persian Gulf and the Sea of Oman. The new species D. spinigerus is mainly characterized by the tail tip of both sexes terminating in two shaply pointed spikes (one dorsal and one ventral) and bearing a pair of minute lateral cuticular spines at its base, situation of both deirids and the excretory pore well posterior to the level of the posterior end of oesophagus, absence of a precloacal sucker and the presence of one or two intestinal caeca. The male and small mature females of the gonad-infecting species P. otolithi are described for the first time, based on light and scanning electron microscopical studies. The male of P. otolithi is most similar to that of P. johnii Moravec et Ali, 2013, but differs from it by the structure of the cephalic end and the number of caudal papillae; both species also differ from each other by the presence of transverse lamellae in the buccal cavity of gravid and subgravid females of P. otolithi, which are missing in those of P. johnii.

Characterization of ecto- and endoparasite communities of wild Mediterranean teleosts by a metabarcoding approach

et al. 2019

Next‐generation sequencing methods are increasingly used to identify eukaryotic, unicellular and multicellular symbiont communities within hosts. In this study, we analyzed the non-specific reads obtained during a metabarcoding survey of the bacterial communities associated to three different tissues collected from 13 wild Mediterranean teleost fish species. In total, 30 eukaryotic genera were identified as putative parasites of teleosts, associated to skin mucus, gills mucus and intestine: 2 ascomycetes, 4 arthropods, 2 cnidarians, 7 nematodes, 10 platyhelminthes, 4 apicomplexans, 1 ciliate as well as one order in dinoflagellates (Syndiniales). These results highlighted that (1) the metabarcoding approach was able to uncover a large spectrum of symbiotic organisms associated to the fish species studied, (2) symbionts not yet identified in several teleost species were putatively present, (3) the parasitic diversity differed markedly across host species and (4) in most cases, the distribution of known parasitic genera within tissues is in accordance with the literature. The current work illustrates the large insights that can be gained by making maximum use of data from a metabarcoding approach.
