On the date and organ of publication for the endemic Galápagos scorpion Centruroides exsul (Scorpiones: Buthidae) by Wilhelm Meise, with a revision of its distribution and type material
Ecuador, nomenclature, South America, Taxonomy
There are conflicting statements in the literature about the date and organ of publication for the endemic Gala ´pagos scorpion Centruroides exsul (Scorpiones: Buthidae) by Wilhelm Meise. In contrast to what the current authoritative taxonomic references suggest, this species was not described in 1934 but rather in 1933. Before the article containing the description finally was included in Volume 74 of the Norwegian journal Nyt Magazin for Naturvidenskaberne in 1934, it was distributed as a preprint in the form of Volume 39 of the separately issued series Meddelelser fra det Zoologiske Museum, Oslo in 1933. The latter publication, in full agreement with Article 21.8 of the International Code of Zoological Nomenclature, has priority over the former and consequently has to be referred to when citing the original taxonomic reference. The present contribution furthermore reviews the distribution of this species and, due to loss and mislabeling, revises its type material.
