Genus Oxypleurodon Miers, 1885

Oxypleurodon Miers, 1885: 588 [type species: Oxypleurodon stimpsoni Miers, 1885 , by monotypy].

Oxypleurodon— Miers 1886: 38.— Tavares 1991: 167, 169.— Ng et al. 2008: 104.— Richer de Forges & Ng 2009a: 2.— Richer de Forges & Ng 2009b: 250.— Richer de Forges 2010: 646.

Nasutocarcinus Tavares 1991: 160 (list), 169.— Ng et al. 2008: 104.

(For the complete synonymy of the genus, see Richer de Forges 2010: 646).

Remarks. There are currently 31 recognised species in this genus ( Richer de Forges & Ng 2009a, b; Richer de Forges 2010; Richer de Forges & Corbari 2012; Lee et al. 2015, 2017). Garth (1958) synonymised the Indo-West Pacific genus Oxypleurodon Miers, 1885 , under Sphenocarcinus A. Milne-Edwards, 1878 , following Alcock (1895, 1899). Sphenocarcinus was then synonymised under Rochinia A. Milne-Edwards, 1875 , by Griffin & Tranter (1986). Subsequently, Tavares (1991) resurrected the genera, Oxypleurodon and Sphenocarcinus (see Lee et al. 2015; Tavares & Santana 2018), and established a new genus for species with a very elongated pseudorostral spine, Nasutocarcinus Tavares, 1991 . Richer de Forges & Ng (2009b) reviewed the taxonomy of both genera, noting that Oxypleurodon is quite distinct from Rochinia , and synonymised Nasutocarcinus under Oxypleurodon (see also Lee et al. 2015). With the description of two new species from PNG, there are now 33 species in Oxypleurodon .
