Sternarchorhynchus oxyrhynchus

Description

Sternarchorhynchus oxyrhynchus (Müller, Troschel, 1848)

St. [Sternarchus] oxyrhynchus Müller, Troschel, 1848: 640. Type locality: Essequibo [Guyana]. Holotype or Syntype: ZMB 4086; 16-18 Zoll TL [470 mm TL; Ellis, in Eigenmann 1912: 438, footnote 71). Described, as new, in more detail in Müller, Troschel (1849: 16, pl. 2, figs. 1, 2).

Sternarchorhynchus Mulleri [sic] Castelnau,1855:95. Type locality: la riviere d’Essequebo [Guyana]. Unneeded replacement name for Sternarchus oxyrhynchus Müller, Troschel, 1848.

Remarks: See discussion in de Santana, Vari (2010b: 333) regarding the uncertainty about whether Müller, Troschel examined more than one specimen. At present, only a single specimen has been found at ZMB.

Distribution: Orinoco River basin; report of the species in Essequibo River probably erroneous (de Santana, Vari, 2010b).
