“…An unusual feature of this worm is the dorsal position of the excretory pore, which occurs at about the level of the caecal terminations. N. dorsoporum, found more or less exclusively in coral reef fishes of the family Chaetodontidae, is unusual in its dorsal genital pore (Machida and Uchida 1987, Bray et al 1994, Hassanine and Gibson 2005, Hassanine 2006b). …”

The phylogenetic relationships of representative species of the superfamily Lepocreadioidea were assessed using partial lsrDNA and nad1 sequences. Forty-two members of the family Lepocreadiidae, six putative members of the Enenteridae, six gyliauchenid species and one Gorgocephalidae, were studied along with 22 species representing 8 families. The Lepocreadioidea is found to be monophyletic, except for the two species of the putative enenterid genus Cadenatella, which are found to be only distantly related to the lepocreadioids. The Lepocreadioidea is formed of five clades in a polytomy, the Gorgocephalidae, a clade containing the Enenteridae and Gyliauchenidae, a small clade of atypical lepocreadiines and the deep-sea lepidapedine lepocreadiids, a small clade consisting of a freshwater form and a group of shallow-water putative lepidapedines and the final clade includes the remaining lepocreadiids. Thus, the generally accepted concept of the Lepocreadiidae is polyphyletic. The Enenteridae (minus Cadenatella) and the Gyliauchenidae are jointly and individually monophyletic, and are sister groups. The nad1 gene on its own places a deep-sea lepocreadiine with the deep-sea lepidapedines, whereas lsrDNA, combined sequences and morphology place this deep-sea lepocreadiine within a group of typical lepocreadiids. It could not be demonstrated that a significant proportion of sites in the nad1 gene evolved under positive selection; this anomalous relationship therefore remains unexplained. Most deep-sea species are in a monophyletic group, a few of which also occur in shallow waters, retaining some characters of the deep-sea clade. Many lepocreadioid species infect herbivorous fish, and it may be that the recently discovered life-cycle involving a bivalve first intermediate host and metacercariae encysted on vegetation is a common life-cycle pattern. The host relationships show no indication of co-speciation, although the host-spectrums exhibited are not random, with related worms tending to utilize related hosts. There are, however, many exceptions. Morphology is found to be of limited value in indicating higher level relationships. For example, even with the benefit of hindsight the gyliauchenids show little morphological similarity to their sister group, the Enenteridae.

“…The new species also resembles M. maillardi described from its type-host, S. aurata, M. crassigula (Linton, 1910) Bartoli, Bray & Gibson, 1989 from Diplodus sargus, D. vulgaris (Geoffroy Saint-Hilaire) and Pagellus erythrinus (L.) as described by Bartoli et al (1989) and Macvicaria chrysophrys (Nagaty & Abdel-Aal, 1969) Bray, 1985 in relation to the distribution of dorsal vitelline follicles in the forebody, but differs in the much larger ventral sucker relative to body width and in the location of the cirrus-sac (predominantly dorsal to the ventral sucker vs predominantly in the forebody) (see Nagaty & Abdel-Aal, 1969;Bartoli et al, 1989;Hassanine & Gibson, 2005).…”

Molecular evidence for the existence of species complexes within Macvicaria Gibson & Bray, 1982 (Digenea: Opecoelidae) in the western Mediterranean, with descriptions of two new species

Morphological and molecular characterisation of specimens of Macvicaria spp. (Digenea: Opecoelidae) from five species of Mediterranean sparids (Teleostei: Sparidae) sampled in the Bizerte Lagoon and the Bay of Bizerte (Tunisia) revealed the presence of two species complexes designated as ''obovata'' and ''crassigula'' groups. Detailed comparative morphological and phylogenetic analyses revealed that two of the specimen sets, one from each complex, represent species new to science. M. maamouriae n. sp. from Sparus aurata L. and Lithognathus mormyrus (L.) appeared genetically similar to M. obovata (Molin, 1859) but differs in having a much larger ventral sucker relative to body width, a cirrus-sac extending dorsally to the posterior margin of the ventral sucker or more posterior, vitelline fields comprising distinctly more abundant vitelline follicles, reaching the level of the pharynx both ventrally and dorsally and confluent dorsally in the forebody, and an ovary contiguous with the anterior testis. Macvicaria bartolii n. sp. from Diplodus annularis (L.) and Spondyliosoma cantharus (L.) belongs to the ''crassigula'' group and is characterised by having almost exclusively dorsal vitelline follicles forming two non-confluent fields in the forebody. Additional morphological data are provided for Macvicaria dubia (Stossich, 1905), a poorly known parasite of Oblada melanura (L.). Morphological descriptions are associated with ITS1-5.8S-ITS2 and 28S rDNA sequences for the three Mediterranean species of Macvicaria Gibson & Bray, 1982. The results of our study suggest that further exploration of the species diversity within this genus should be based on both morphological and molecular data.

“…chrysophrys, according to Nagaty & Abdel-Aal (1969) and Hassanine & Gibson (2005), is a less elongate species with a width to length ratio of 1:2.3 [2.7-2.9]; it has a longer forebody (39 [31-43]% of the body-length); a shorter post-testicular area (17% of body-length) and larger eggs (80 × 50 [64-78 × 35-48 (71 × 42)]. …”
