The systematics of Diplostomum species, common intestinal parasites of piscivorous birds, has long been problematic, owing to phenotypic plasticity and the paucity of morphological features that are often subject to age- and host-induced variation. We sequenced the ITS1-5.8S-ITS2 regions of the rDNA from adult Diplostomum huronense , Diplostomum indistinctum, and Diplostomum baeri obtained from experimentally infected ring-bill gulls ( Larus delawarensis) and compared them with partial ITS1…

A New Genus of Diplostomids (Digenea: Diplostomoidea) from the Nile Crocodile in South Africa with a Key to Diplostomid Genera

A new key to diplostomid genera is provided, considering the substantial systematic changes and newly erected genera since the previously published key to phytochemical affinities of these new taxa.

Another plea for ‘best practice’ in molecular approaches to trematode systematics: Diplostomum sp. clade Q identified as Diplostomum baeri Dubois, 1937 in Europe

The current study is another step in elucidating the species spectrum of Diplostomum based on integrative taxonomy with well-described morphology of adults linked to sequences and extends the recommendations of Blasco-Costa et al. (2016, Systematic Parasitology 93, 295–306) for the 'best practice' in molecular approaches to trematode systematics.

Molecular and morphological characterization of Austrodiplostomum ostrowskiae Dronen, 2009 (Digenea: Diplostomatidae), a parasite of cormorants in the Americas

A link between the metacercariae in fish and the adults in cormorants was established, indicating also that a single species is found in the distribution range comprising southern USA, southwards to Venezuela.

Assessing the genetic diversity of the metacercariae of Posthodiplostomum minimum (Trematoda: Diplostomidae) in Middle American freshwater fishes: one species or more?

Assessment of the genetic divergence and phylogenetic relationships of metacercariae sampled from several host species in a wide geographical range across Middle America contributes to the understanding of the diversity of larval forms of diplostomids and provides an opportunity to further study their life cycles.

Integrative taxonomic approach to the cryptic diversity of Diplostomum spp. in lymnaeid snails from Europe with a focus on the ‘Diplostomum mergi’ species complex

Morphometric and molecular analyses of Tylodelphys sp. metacercariae (Digenea: Diplostomidae) from the vitreous humour of four fish species from Lake Naivasha, Kenya

Morphometric and molecular data used to discriminate species and inferred a single unidentified species of Tylodelphys metacercariae, which is not conspecific with any other diplostomid for which comparable molecular data are available, including four species known from siluriform fish in Nigeria and Tanzania.



Systematic relationships among six species of Diplostomum Nordmann, 1832 (Digenea) based on morphological and molecular data*

It was demonstrated that the phylogenetic trees obtained for morphological data at cercaria!, metacercarial and adult stages, as well as all characters together differ in branch topology from one another.

Differentiation of Mexican species of Haematoloechus looss, 1899 (Digenea: Plagiorchiformes): molecular and morphological evidence.

Molecular evidence is interpreted in the light of morphology to examine the validity of several species of Haematoloechus described as Mexican endemics, including H. medioplexus, which is distributed along the east coast coinciding with the distribution of Rana berlandieri.

Species diversity among the genus Monorchis (Digenea: Monorchiidae) parasitic in marine teleosts: molecular, morphological and morphometrical studies with a description of Monorchis blennii n. sp.

Abstract. Molecular, morphological and morphometrical studies were conducted on two species of the genus Monorchis (Monorchiidae), Monorchis parvus and Monorchis monorchis, collected in different

Molecular and morphological differentiation between species of the Plagiorchis vespertilionis group (Digenea, Plagiorchiidae) occurring in European bats, with a re-description of P. vespertilionis (Müller, 1780)

Morphological study of the material in collections revealed characters which enable the species of Plagiorchis from bats in Europe to be distinguished, and a neotype is established and described.

Inference of phylogeny and taxonomy within the Didymozoidae (Digenea) from the second internal transcribed spacer (ITS2) of ribosomal DNA

DNA sequences of the second internal transcribed spacer of ribosomal DNA (rDNA) were determined for 11 species from four genera of Didymozoinae and found the gonochoristic species, I. pearsoni and I. suttiei, to be genetically similar to the hermaphroditic species in the genus Indodidymozoon and found no evidence to indicate that they belong in a separate genus.

Nuclear rDNA ITS sequence variation in the trematode genus Echinostoma: an aid to establishing relationships within the 37-collar-spine group

DNA sequence data from the nuclear rDNA ITS1, 5·8S and ITS2 of 7 nominal species belonging to the 37-collar-spine group within the genus Echinostoma provides a model for future work on sibling species and will assist in the current reclassification of the group.

The identification and morphological variation of Diplostomum baeri bucculentum from two gull species, using metacercarial infections from least cisco from the Northwest Territories

An analysis of morphological characters from 258 gravid specimens showed a greater range in measurements than previously reported for this species, and characters such as egg numbers and size and shape components were strongly influenced by host effects.
