title: Names and publication dates of the Brachyura in F.É. Guérin (Guérin-Méneville) (Crustacea: Decapoda).
abstract: The names and dates of the publications of Brachyura of Guérin (Guérin-Méneville from 1836) are reviewed, and previously unidentified or overlooked names are identified. Several identical new names used in multiple publications by Guérin (also under the name Guérin-Méneville), and others that appeared in the same year necessitated the accurate determination of publication dates to establish priority. The authorships of three names should be credited to Guérin (1832): Gecarcinus lateralis (Gecarcinidae), Halimus aries (Majidae), and Libinia spinosa (Epialtidae), the first previously attributed to Fréminville (1835), the last two to H. Milne Edwards (1834). The overlooked genus- and species-group names Cyclocarcinus pinnotheroides Guérin-Méneville, 1838, are determined to be senior subjective synonyms of the genus- and species-group names Hapalonotus reticulatus (De Man, 1879) (Pilumnidae). Applying Article 23.9.1 of the International Code of Zoological Nomenclature, precedence is reversed between the genus-group names and the correct name is Hapalonotus pinnotheroides (Guérin-Méneville, 1838). Current and widespread use of the genus-group name Thalamita Latreille, 1829 (31 March) (Portunidae) is threatened by the overlooked Thalamites Guérin, 1829 (21 March), and the precedence of the names is also reversed to maintain usage of the former. The genus-group name Eurypodius Guérin (Inachidae) is shown to have been established in 1828, not 1825. Included is a complete bibliography of the publications in which Guérin (also under Guérin-Méneville) established new names for Brachyura, with their accurate publication dates.
