Pleopods 3 – 5 are absent in most male chirostylids, but are vestigial in some species of Gastroptychus (e. g., G. rogeri Baba, 2000, and G. investigatoris (Alcock & Anderson, 1899), K.

F868FC00C649FFC87C8DFB33FD32A2DF.taxon	discussion	Remarks. The Eumunidiens group of A. Milne-Edwards & Bouvier, 1894, was used in the vernacular sense and as such is an informal name and not available under the International Code of Zoological Nomenclature (see Ng et al. 2008 for discussion of vernacular names as used by A. Milne-Edwards and Bouvier). However, A. Milne-Edwards & Bouvier (1900), regarding Eumunida as belonging to a Tribe within the Diptycinae, used the Latinized form, Eumunidae, and thus validated the name. Eumunidae has not since been used. In now recognising a separate family, Eumunididae, for Eumunida and Pseudomunida, we attribute authorship to A. Milne-Edwards & Bouvier (1900).	en	Schnabel, Kareen E., Ahyong, Shane T.
