Abstract
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 being a junior homonym of a generic nomen of fishes. Such mistakes are not new, many other similar ones having been published in the recent years. All taxonomists should give the proper attention to the nomenclatural Rules of the Code when proposing new nomina.
