Revision of the genus Glyphithyreus Reuss, 1859 (Crustacea, Decapoda, Brachyura, Xanthoidea) and recognition of a new genus

Paleobiogeography of Southern Hemisphere Decapod Crustacea

“…Brazil (Feldmann and Martins-Neto, 1995) as well as in the paleotemperate region of southern Argentina. Lobulata, Rocacarcinus, Chirinocarcinus Karasawa and Schweitzer (2004), and Ctenocheles were confined to the paleotemperate region in Argentina Schweitzer et al, 2004). Metanephrops is known from high southern latitudes in Antarctica (Feldmann, Tshudy et al, 1993), Glyphea has been described from New Zealand (Feldmann, 1993), Linuparus is known from Chile (Feldmann, Tshudy et al, 1993), and Hoploparia has been recognized in Antarctica (Feldmann, Tshudy et al, 1993) and Argentina (Aguirre-Urreta, 1989).…”

A new classification of the Xanthoidea sensu lato (Crustacea: Decapoda: Brachyura) based on phylogenetic analysis and traditional systematics and evaluation of all fossil Xanthoidea sensu lato

“…Family Euryplacidae Stimpson, 1871 Included fossil genera. Chirinocarcinus Karasawa and Schweitzer, 2004;Chlinocephalus Ristori, 1886;Corallicarcinus Müller and Collins, 1991; Eucrate De Haan, 1835 (also extant); Euryplax Stimpson, 1859 (also extant); Orbitoplax Tucker and Feldmann, 1990;Paleopsopheticus Hu and Tao, 1996;Simonellia Vinassa de Regny, 1897;Stoaplax Vega, Cosma et al, 2001; Viaplax Karasawa and Kato, 2003a. Occurrence. Paleocene -Recent.…”

Revision of species Plagiolophus sulcatus Beurlen, 1939 (Decapoda, Brachyura) from the Oligocene of Hungary and Slovenia

“…The holotype of the species is refigured for the first time here since its original publication. Attribution of P. sulcatus to Glyphithyreus, first suggested by Karasawa & Schweitzer (2004), is confirmed. Comparison with congeners suggests that G. sulcatus is differentiated by having subtriangular protogastric regions and fewer and coarser tubercles on elevated carapace regions.…”

“…The ghost shrimps of this assemblage have since received proper re-evaluation (Hyžný & Dulai, 2014), the three species of brachyuran crabs, including Plagiolophus sulcatus, remained unrevised in respect with modern classification until now. This species was tentatively retained in the genus Plagiolophus Bell, 1858(non Pomel, 1857 by Karasawa & Schweitzer (2004) in their revision of Glyphithyreus Reuss, 1859. Those authors noted that, "the placement of G. sulcatus is somewhat tentative and is based upon our translation of Beurlen's (1939) original description in German and the very poorly reproduced illustration in our copy of the work (Karasawa & Schweitzer, 2004, p. 148)".…”
