In September 2012, the International Code of Zoological Nomenclature was amended in order to allow the online publication of new nomina and nomenclatural acts, provided some conditions are respected. One of them is that such electronic publications be pre- and postregistered in the database Zoobank, and that this registration be mentioned in their...

The publication dates of the printed issues of the Bulletin de la Société zoologique de France from 1876 to 2015 (volumes 1–139) were searched. Of the 3953 new nomina published, no less than 1224 (31 %) appeared after the ostensible year of the volume. Information on the issues, their pagination, publication dates, as well as the new nomina contain...

This sixth report of activities of the Linz Zoocode Committee is devoted to the result of the enquiry launched by this Committee in 2021 about the status of new nomina and nomenclatural acts published so far on CD-ROMs. After a discussion of some problems of interpretation raised by Articles 8.4.2, 8.1.2 and 9.12 of the Code, we provide information...
Article
The nomen of the family Dermochelyidae, with currently a single extant species, Dermochelys coriacea (Vandellius, 1761), has been attributed to different authors. This situation led us to research the sources and information about the various nomina (families, genera and species) concerned in order to review their status, in compliance of the Code,...

Comparative studies of mortality in the wild are necessary to understand the evolution of aging; yet, ectothermic tetrapods are underrepresented in this comparative landscape, despite their suitability for testing evolutionary hypotheses. We present a study of aging rates and longevity across wild tetrapod ectotherms, using data from 107 population...

In 1847, Dufour proposed the nomen Salamandra tuberculata, a senior synonym of Hemitriton asper, for the taxon currently recognized as Calotriton asper (Dugès, 1852). In order to sustain stability, the predominant usage should be maintained. We present here the conditions required by article 23.9 of the International Code of Zoological Nomenclature...

Cryptobranchus alleganiensis (Sonnini & Latreille, 1801b) was long considered the only species of the genus Cryptobranchus Leuckart, 1821. In this genus, Sabatino & Routman (2009) found eight genetic independent unities isolated from each other, which they treated as Management Units. Later, Hime (2017) recovered five strongly supported species-lev...

Significance Using long-term demographic studies, we showed that warmer temperatures are associated with increased senescence rates and decreased lifespans in four amphibian species that are widely distributed across two continents (North America and Europe). Our study highlights the role of changing climatic conditions in the aging of ectotherms i...

The ‘suppression’ (invalidation) for nomenclatural purposes by the International Commission on Zoological Nomenclature of the work Histoire Naturelle des Quadrupèdes Ovipares et des Serpens first published by La Cepède from 1788 to 1790 brought no benefit of any kind to zoological taxonomy and nomenclature but generated several nomenclatural proble...

The publication date, availability and onymotope of the nomen Scincus cyanurus are assessed. The nomen was validly published by Lesson in 1830 and is based on a holophoront, probably from the island of Tahiti. Elements allowing the identification of the nomina cited in the synonymy of Scincus cyanurus are given. Eumeces lessonii Duméril & Bibron, 1...

A taxon, traditionally referred to the rank order, encompassing all recent taxa of caecilians and their close fossil relatives, is highly supported as holophyletic in all recent cladistic analyses of Amphibia. Under the Duplostensional Nomenclatural System, among 12 nomina available in the literature, only one, Gymnophiona Rafinesque, 1814, qualifi...

The nomenclatural status of 17 class-series nomina (13 diplorhizonyms and 4 haplorhizonyms), based on the single or primary stems Anura, Urodela and Batrachia that had been set aside in our previous papers of this series is examined. None of them is currently valid under the Duplostensional Nomenclatural System, four of them are unavailable (includ...
Article
Under the Duplostensional Nomenclatural System, the valid nomen of the class including all recent amphibians and all the Palaeozoic groups of anamniote tetrapods subsequent to the ‘lissamphibian-amniote phylogenetic split’ is the sozodiaphonym Amphibia Blainville, 1816. This corresponds to the usage that has been in force for two centuries in thous...

A taxon encompassing all recent taxa of amphibians and their close fossil relatives is highly supported as holophyletic in all recent phylogenetic analyses of amphibians. Under the Duplostensional Nomenclatural System, among twenty nomina available for this taxon, only one, Lissamphibia Gadow, 1898, qualifies as a sozodiaphonym and appears to be th...

A taxon, traditionally referred to the rank order, encompassing all recent taxa of salamanders and their close fossil relatives, is highly supported as holophyletic in all recent phylogenetic analyses of amphibians.

Article
The nomen Batrachia has been very extensively used in the scientific literature since 1800, but for two different taxa of recent amphibians. The first one, originally introduced by Brongniart (1800), corresponds to a taxon encompassing all recent taxa of frogs and salamanders but excluding the caecilians. The second one, used first by Oppel (1811),...

In July 2014, the international meeting ‘Burning questions and problems of zoological nomenclature’ was held in Linz (Austria). It acknowledged the presence in the current International Code of Zoological Nomenclature of a number of severe problems, and accordingly decided the creation of a new international body, the Linz Zoocode Committee (LZC),...
Article
Starting from a finding concerning a few specific nomina proposed by Linnaeus (1758, 1760) and Linné (1766–1767) in herpetology, we returned to the ‘rules of nomenclature’ followed, more or less explicitly, in taxonomic works of the 18th century, in an attempt to understand the status of capitalised epithets. We conclude that such epithets were vie...

In the scientific literature, the availability, authorship, date and onomatophore of the four generic nomina of lizards "Platydactyles", "Hemidactyles", "Thecadactyles" and Ptyodactyles" published by Cuvier (1816) and of the genus nomen of toads "Otilophes" published by Cuvier (1829) as French scientific nomina in the plural, and of their latinised...

In two distinct works published in 1877, Cope described three fossil genera of vertebrates, Hedronchus, Hemitrypus and Scapherpeton, which are now considered to be based on a single species of urodelan amphibian. The respective dates of publications of these works require to adopt Hedronchus sternbergii as the valid nomen of this taxon, which is no...

A precise terminology is proposed for the distinction between different categories of onymotopes (type localities) in zoological nomenclature. To illustrate these new terms, we give concrete examples taken from nomina of African amphibians. In the course of working on these examples, we are led to designate a lectophoront (lectotype) for the frog s...

The new genus-series nomen Relictus, proposed by Sá et al. (2018) for a subgenus of the frog genus Chiasmocleis Méhelÿ, 1904, is unavailable for having been proposed [1] in a paper published online unregistered in Zoobank and [2] without a diagnosis stating in words characters purported to differentiate the taxon. Finally, it is also invalid for be...

The purpose of this application, under Article 81 of the Code, is to conserve the name dicroglossidae Dubois, 1987 for a family of frogs.

In zoological nomenclature, to be potentially valid, nomenclatural novelties (i.e., new nomina and nomenclatural acts) need first to be made available, that is, published in works qualifying as publications as defined by the International Code of zoological Nomenclature (“the Code”). In September 2012, the Code was amended in order to allow the rec...

For a long time, and although the two genera are not closely allied, generic allocation of the species of the genera Arthroleptis (Anura, Brevi-cipitidae, Arthroleptinae) and Phrynobatrachus (Anura, Ranidae, Phryno-batrachinae) was found difficult by zoologists. However, Laurent (1941) had pointed to criteria allowing this allocation, bearing on th...
