“…Madhavi (2011) used the combination O. overstreeti , while fully aware that it is a homonym of O. overstreeti Ahmad 1985. The two names in question were erected in the same volume and part of the journal, but Retractomonorchis overstreeti was introduced on p. 19 and Opisthomonorcheides overstreeti on p. 250.…”

Three species of Opisthomonorcheides Parukhin, 1966 are reported for the first time from Indonesian waters: O. pampi (Wang, 1982) Liu, Peng, Gao, Fu, Wu, Lu, Gao & Xiao, 2010 and O. ovacutus (Mamaev, 1970) Machida, 2011 from Parastromateus niger (Bloch), and O. decapteri Parukhin, 1966 from Atule mate (Cuvier). Both O. pampi and O. ovacutus can now be considered widespread in the Indo-Pacific region, with earlier records of these species being from Fujian Province, China and Penang, Malaysia, respectively. We redescribe O. decapteri from one of its original hosts, Atule mate, off New Caledonia, and report this species from Jakarta Bay, Indonesia, extending its range throughout the Indian Ocean into the south-western Pacific. All three species possess a genital atrium that is long, sometimes very long, and a genital pore that is located in the forebody. This validates the interpretation that the original description was erroneous in reporting the genital pore in the hindbody, well posterior to the ventral sucker. These observations verify the synonymy of Retractomonorchis Madhavi, 1977 with Opisthomonorcheides. A major discrepancy between the species of Opisthomonorcheides is that some are described with the uterus entering the terminal organ laterally and some with it entering terminally; this feature needs further analysis. Based on the length of the genital atrium and the posterior extent of the vitellarium, the 27 species of Opisthomonorcheides considered valid can be divided into four groups. Among the 53 host records analysed, the families Carangidae (53% of records), Stromateidae (17%) and Serranidae (5.7%) are the most common; the reports are overwhelmingly from members of the Perciformes (91%), with further records in the Clupeiformes (5.7%), Gadiformes (1.9%) and Pleuronectiformes (1.9%). Two fish genera (Parastromateus Bleeker and Pampus Bonaparte) dominate the recorded hosts, with the black pomfret Parastromateus niger harbouring six species, the silver pomfret Pampus argenteus (Euphrasen) harbouring six, and the Chinese silver pomfret P. chinensis (Euphrasen) two. A host-parasite checklist is presented. We discuss the host-specificity of members of the genus, questioning some records such as that of O. decapteri in a deep-sea macrourid. We also comment on the morphological similarity, but phylogenetic distance, between the various Pomfret species, advancing the possibility that a series of host misidentifications has occurred. Sequences of the ITS2 rDNA gene generated for O. pampi and O. ovacutus are briefly discussed and molecular data are lodged in the GenBank database.

“…Adult cephalogonimids have a genital pore at or near the anterior extremity and a long cirrus-sac terminating at different levels in the forebody (Jones & Bray, 2008). It comprises five genera: Cephalogonimus Poirier, 1886; Paracephalogonimus Skrjabin, 1950;Cephalogonimoides Brooks & Buckner, 1976;Emoleptalea Looss, 1900;and Masenia Chatterji, 1933. Species of Masenia (syns Eumasenia Srivastava, 1951 andPseudomasenia Pan, 1984) inhabit the intestine of marine and freshwater fishes of the class Actinopterygii throughout Africa and Asia (Jones & Bray, 2008;Madhavi, 2011). Adults of species of Masenia can be distinguished from the other cephalogonimids by the possession of two rows of enlarged circumoral spines and vitelline follicles located mainly in the hindbody (Beverley-Burton, 1962;Jones & Bray, 2008).…”

Masenia nkomatiensis n. sp. (Digenea: Cephalogonimidae) from Clarias gariepinus (Burchell) (Clariidae) in Incomati Basin, Mozambique

A new species of Masenia Chatterji, 1933 is described based on material from the intestine of Clarias gariepinus (Burchell) in the Incomati River, Mozambique. The combination of morphological characteristics and analysis of 18S and 28S rDNA sequences delineated the specimens found in the present study as a distinct species. The new form is distinguished from other Masenia spp. in having a large reniform seminal receptacle, a cirrus-sac ending anterior to the ventral sucker, intestinal caeca extending into the hindbody to the level of the posterior testis, and the vitelline fields extending anteriorly to the ventral sucker and posteriorly to the middle of the ovary. Notably, the new form is the only record of African species having a sac-shaped excretory vesicle. Analysis of 28S rDNA sequence data supported its placement in the Cephalogonimidae Looss, 1899. 18S analyses also supported its placement in this family but showed it was not closely related to Masenia bangweulensis (Beverley-Burton, 1962), the sole other African species for which genetic data is currently accessible. The total pairwise differences for 18S and 28S sequences showed the new form differing from other cephalogonimids. Thus, both morphological and genetic characteristics indicate that the present form represents a distinct species, here described as Masenia nkomatiensis n. sp. An updated key to African Masenia spp., now five, is provided. This article was registered in the Official Register of Zoological Nomenclature (ZooBank) as CD42E301-768B-498B-8B67-80FDA85BB40A.

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.
