Redescription of Paradiplozoon hemiculteri (Monogenea, Diplozoidae) from the type host Hemiculter leucisculus, with neotype designation

open access: yesParasite, 2018
Paradiplozoon hemiculteri (Ling, 1973), a member of the Diplozoidae, parasitizes the gills of Asian fish. Not only is the type material unavailable for this species, the original description was poor and somewhat conflicting, and adequate molecular data ...

Exploring the cranial morphology and possible convergences of Triassic non‐crocodylomorph pseudosuchians (Archosauria: Pseudosuchia) with other sauropsids through linear morphometrics

open access: yesThe Anatomical Record, EarlyView.
Abstract Triassic pseudosuchians had highly diversified cranial morphologies. These archosaurs occupied diverse ecological roles, ranging from terrestrial predators and herbivores to semiaquatic ambush predators and possible waders. Here, we apply linear cranial morphometrics to assess possible convergences with other sauropsids from the clades ...

Towards a unified publicly accessible database of avian type specimens

open access: yesIbis, EarlyView.
Type specimens represent the crucial physical reference for any scientific bird name, but type material is scattered widely across the globe, and there is still no one comprehensive source documenting the presence, status and condition of all avian type specimens, as well as associated information on nomenclature and the validity of individual names ...

Neotype designation for Thymallus aeliani Valenciennes, 1848 from a museum topotype specimen and its affiliation with Adriatic grayling on the basis of mitochondrial DNA [PDF]

open access: yesZooKeys, 2020
In 1848, the grayling Thymallus aeliani (Valenciennes) was described from Lake Maggiore, Italy, in the north Adriatic basin. Genetic analyses of the mitochondrial control region showed a unique evolutionary history of grayling inhabiting the rivers of ...

Molecular phylogenetic analysis sheds light on the diversity and evolutionary history of the Neotropical and African Triplophyllum (Tectariaceae)

open access: yesJournal of Systematics and Evolution, EarlyView.
We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.

Neotype designation for the Australian Pig-footed Bandicoot Chaeropus ecaudatus Ogilby, 1838

open access: yesRecords of the Australian Museum, 2020
The original description of the now extinct Australian Pig-footed Bandicoot Chaeropus ecaudatus Ogilby, 1838 was based on one specimen from which the tail was missing. Re-examination of the skull thought to be the holotype of C.

Anchonini in Africa: New Species and Genus Confirming a Transatlantic Distribution (Coleoptera: Curculionidae: Molytinae)

open access: yesDiversity, 2018
The Anchonini known from Africa are reviewed. The monotypic genus Aethiopacorep is redescribed. The new West African genus Titilayo gen. nov. is described, with seven new species: four from São Tomé, T. perrinae sp. nov., T. saotomense sp.

An integrative redescription of Echiniscus quadrispinosus quadrispinosus Richters, 1902 (Heterotardigrada, Echiniscidae) from the terra typica in Taunus Mountain Range (Europe; Germany)

open access: yesEuropean Journal of Taxonomy, 2022
In the present study, we used an integrative taxonomy approach to redescribe a population of Echiniscus quadrispinosus quadrispinosus Richters, 1902 from the neotype locality in the Taunus Mountain Range (Germany).

Evidence for the true type-locality of Rhamdia quelen (Siluriformes: Heptapteridae), and the geographical origin and invalid neotype designation of four of its synonyms [PDF]

open access: yesNeotropical Ichthyology, 2020
Historical information on the probable type-locality of Pimelodus quelen and of its four junior synonyms that share the same neotype, Pimelodus namdia, Pimelodus sebae, Heterobranchus sextentaculatus, and Silurus rivularis, is presented and discussed ...
