The species are represented by Hoploparia sp., Linuparus wilcoxensis Rathbun, 1935, an unnamed paguroid, Kierionopsis nodosa Davidson, 1966, Pithonoton cardwelli new species, Caloxanthus sp., Macroacaena johnsoni (Rathbun, 1935), new combination, Raninoides bournei (Rathbun, 1928), R. treldenaesensis (Collins and Jakobsen, 2003), Prehepatus sp., Tehuacana americana (Rathbun, 1935), new combination, Costacopluma texana new species, Paraverrucoides alabamensis (Rathbun, 1935) and Viapinnixa mexiaensis new species. Morphological details unknown for previously described species are included. New systematic placements are offered based on recent research. Intraspecifi c morphological variation is documented for the goneplacoid crab Tehuacana americana. Costacopluma texana is the second Paleogene species of that genus in southeastern USA, and because of its abundance represents the most completely described species for the genus. This fauna represents one of the most diverse assemblages of Paleocene crustacean decapods. Key words: Paleocene, Crustacea, Mexia, Texas.

Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many resolved. Detailed notes and references are provided where necessary. The constitution of a large number of families and superfamilies is discussed in detail, with the positions of some taxa rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the nomenclature of any large group of decapod crustaceans has been examined in such detail.

Cold seeps fluids provide an additional source of energy for various sulfide- and 27 hydrocarbon-harvesting bacteria, often in symbiosis with invertebrates, attracting a variety of other 28 organisms including crustaceans (e.g., Levin 2005; Vanreusel et al. 2009; Vrijenhoek 2013). The 29 percentage of crustaceans of all macrofaunal specimens is highly variable locally in modern seeps, from 30 0–>50% (Dando et al. 1991; Levin et al.

For over 140 years, convergent evolution of the crab-like body plan (with a wide and flattened shape, and a bent abdomen) at least five times in decapod crustaceans has been known as ‘carcinization’. The repeated loss of this body plan has been identified as ‘decarcinization’. We offer phylogenetic strategies to include poorly known groups, and direct evidence from fossils, that will resolve the pattern of crab evolution and the degree of phenotypic variation within crabs. Proposed ecological advantages of the crab body are summarized into a hypothesis of phenotypic integration suggesting correlated evolution of the carapace shape and abdomen. Our premise provides fertile ground for future studies of the genomic and developmental basis, and the predictability, of the crab-like body form. Keywords: Crustacea, Anomura, Brachyura, Carcinization, Phylogeny, Convergent evolution, Morphological integration 1 © 2020 by the author(s).

E-mail: [email protected] Abstract Rhadinoplax, new genus, is described for Carcinoplax microphthalmus Guinot & Richer de Forges, 1981, a species pre- viously included in the family Goneplacidae MacLeay, 1838. The new genus is transferred to the family Progeryonidae Števčić, 2005, superfamily Goneplacoidea. The poorly known progeryonid, Paragalene Kossmann, 1878, is also redescribed and figured. Key words: Crustacea, Decapoda, Brachyura, Goneplacoidea, Progeryonidae, Rhadinoplax new genus, Carcinoplax microphthalmus, Paragalene longicrura, Progeryon Introduction In his revision of the Goneplacidae MacLeay, 1838, Castro (2007) left the status of Carcinoplax microphthal- mus Guinot & Richer de Forges, 1981, unresolved. He stated that while it was clearly not a species of Carci- noplax H. Milne Edwards, 1852, it was also not a member of the Goneplacidae as he defined it, and commented that it had affinities with the Euryplacidae Stimpson, 1871. Similarly, the affinities of the poorly known Paragalene longicrura (Nardo, 1868) have not been clear, although it was most recently referred to the Progeryonidae Števčić, 2005, by Ng & Manuel-Santos (2007). The problems of the Goneplacidae and Goneplacoidea are challenging, and often confusing (see Guinot & Breton 2006; Ng & Manuel-Santos 2007; Castro 2007), but the situation has become much clearer in recent years.
