Zoological nomenclature is the discipline of taxonomy responsible for regulating the scientific names of animal species. It has its roots in Carolus Linnaeusʼ work and has been governed by an international Code since the turn of the 20th century. Its vocabulary, on the other hand, is not always clear. Various authors have established new terminolog...

Just after the publication of our paper (Dubois et al. 2021), we discovered that, in Table 1, pages 443 and 444 are identical, and the actual page 443 is missing. We here provide this page, and we took this opportunity to correct a few other errors in this paper. We provide below corrections only in the case of misspellings or other errors that may...
Article
The first issue of the journal Bionomina was published by Magnolia Press (Auckland, New Zealand) on 24 December 2010. The journal originated from an evolution and expansion of the section ‘Theory and methodology’ introduced in 2006 in the journal Zootaxa, itself founded in 2001 (Zhang 2007). The purpose of this new journal was wider than that of th...
Article
The African reedfrog taxon Alexteroon consists of only three described species with rather restricted geographical ranges. Although the assignment to a distinct genus is supported by multiple evidence, its position within the larger African hyperoliid radiation has been disputed. Available molecular data are scarce and the geographic records are fe...
Article
Although currently most taxonomists claim to adhere to the concept of ‘phylogenetic taxonomy’, in fact most of the zoological classifications currently published are only in part ‘phylogenetic’ but include also phenetic or gradist approaches, in their arbitrary choices of the nodes formally recognised as taxa and in their attribution of ranks to th...
Article
The dicroglossid genus Sphaerotheca was erected by Günther in 1859, with its range of distribution in South Asia. Since then, 13 species have been described and 10 species are considered valid. Many of these descriptions were from low to mid-elevation ranges of homestead areas, agroecosystems and degraded landscapes with a few from forested areas....

Taxonomic progress is often hindered by intrinsic factors, such as morphologically cryptic species that require a broad suite of methods to distinguish, and extrinsic factors, such as uncertainties in the allocation of scientific names to species. These uncertainties can be due to a wide variety of factors, including old and poorly preserved type s...

For more than a century, Hylarana tytleri (Theobald, 1868) has been confused with two congeneric species, H. taipehensis and H. erythraea, in Bangladesh and neighboring countries, due to phenetic similarities as well as a lack of sufficient molecular and morphometric data. To resolve these problems, we conducted molecular and morphological surveys...

Theory predicts that sexually dimorphic traits under strong sexual selection, particularly those involved with intersexual signaling, can accelerate speciation and produce bursts of diversification. Sexual dichromatism (sexual dimorphism in color) is widely used as a proxy for sexual selection and is associated with rapid diversification in several...

Full-text available
The Code provides no Rules regarding the taxonomic allocation and nomenclatural validity of class-series nomina (for taxa above the rank superfamily), which results in considerable confusion, arbitrariness and instability in higher zoological nomenclature. Currently, authors are ‘free’ to use any system or no system at all, and the only way to prov...
Article
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...
Article
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...
Article
Climate change is now considered as a serious threat to the viability of many species and consequently as one of the major drivers of global biodiversity loss. Amphibians serve critical roles in forest ecosystems and are one of the most sensitive groups to environmental change. Despite the importance of amphibians in forest ecosystems and their sen...

Article 23.9 of the Code, introduced in its last 1999 version, allows the validation, in some cases, of a well known junior synonym or homonym as opposed to a senior synonym or homonym that had been ignored in the literature after 1899. In such cases, the junior nomen qualifies as a nomen protectum and the senior one as a nomen oblitum, a formula r...

We propose to recognise two tribes in the subfamily ACRIDINAE of the family HYLIDAE (AMPHIBIA, ANURA) and we point to nomenclatural problems of homonymy between the nomen of this subfamily and two familial nomina of ORTHOPTERA CAELIFERA. To solve these problems, we propose a solution that requires an action by the International Commission on Zoolog...

Several millions frogs captured in the wild in Indonesia are sold for food yearly in French supermarkets, as deep frozen frog legs. They are commercialized as Rana macrodon, but up to 15 look-alike species might also be concerned by this trade. From December 2012 to May 2013, we bought 209 specimens of deep frozen frog legs, and identified them thr...

Article 11.7.1.1 of the Code states that, to be available, a new zoological family-series (‘family-group’) nomen must be based, not only on an available generic nomen, but also on one used as valid in the newly erected family-series taxon. This Rule is ignored by many practising taxonomists, which may have deleterious consequences in zoological nom...
