Family GECARCINIDAE H. Milne Edwards, 1837

NOMENCLATURE. — In the newly created Thoracotremata Guinot, 1977, a superfamily rank Gecarcinoidea was proposed by Guinot (1977a: 406; 1977b: 1050; 1978: 287). The family-group name Gécarciniens H. Milne Edwards, 1837 meets all the criteria of availability in accordance with the provisions of the Code (ICZN 1999, Art. 11.7, 11.7.2). However, although authority of H. Milne Edwards is explicitly recognised by many carcinologists and despite that Türkay (1970: 335), Prahl & Manjarrés (1983: 32; 1984a: 151) and Tavares (1989: in the title and p. 5, 21) formally assigned authorship to H. Milne Edwards (1837 a), the Gecarcinidae continued to be attributed to MacLeay (1838: 63) by most authors, e.g. by Ng et al. (2008: 30, 214), Guinot et al. (2013: 40, table 7), Ng & Davie (2012: 89), Ng & Shih (2014: 112; 2015: 383; 2023: 2), Davie et al. (2015b: 1117), Ng (2017: 2). Authorship of the family-group name Gecarcinidae was already discussed in detail by Guinot et al. (2018: 602) and Tavares & Mendonça Jr (2022: 9), and is hereby – and we hope – definitively – ascribed to H. Milne Edwards (1837 a).
