Cetopsis starnesi sp.nov. considered to be from Argentina

Cetopsis starnesi    Vari, Ferraris & de Pinna, 2005
is considered to be a species from Argentina.

NEWS: CONFIRMED IN 2006

type locality:
Bolivia, Tarija: Argentinean-Bolivian border, río Bermejo, 4-5 km S of Pueblo Salado, approximately 30 air km S of Bermejo (22°27’S, 64°32’W). Holotype: USNM 314309 (mature male, 77 mm)

remarks (from publication, p. 201):
…Pozzi (1945: 262 and map on page 251) reported Cetopsis caecutiens (= coecutiens) from two localities in northern Argentina, apparently in the río Bermejo basin in the Provinces of Salta and Jujuy. This record by Pozzi was presumably the basis for the later citation of C. coecutiens as a component of the Argentinean ichthyofauna by Ringuelet & Arámburu (1961: 46). Subsequently, Ringuelet et al. (1967: 348) specifically noted that the inclusion of this species in their compendium of freshwater fishes of Argentina was based on Pozzi (1945) but cited C. coecutiens as being present in the Provinces of Salta and Catamarca, rather than Salta and Jujuy as indicated by Pozzi (1945). Specimens of the Cetopsinae examined during this study did not include any samples of C. coecutiens that originated at any locality within the río de La Plata basin. Furthermore, the only species of the Cetopsinae that we examined that originated in the río Bermejo basin was C. starnesi. In light of the available information we tentatively consider the citations of C. coecutiens from northern Argentina by Pozzi (1945), Ringuelet & Arámburu (1961) and Ringuelet et al. (1967) to refer to C. starnesi.
Castello (1969: 407) reported Pseudocetopsis gobioides from a locality close to the junctions of the río San Antonio and the río Bermejo in the Province of Salta, northwestern Argentina. Although Cetopsis gobioides does occur in Argentina in the Provinces of Misiones (MHNG 2389.14), Corrientes (Alonso de Arámburu et al., 1962: 237), and Santa Fé (Oliveros & Rossi, 1992: 77), all of which are located in the northeastern portions of that country, there are no confirmed records of the occurrence of C. gobioides in northwestern Argentina. Neither for that matter are there any records of the latter species from an upland region comparable to that from which the specimens reported by Castello (1969) originated. As noted above the only member of the Cetopsinae known to occur in the río Bermejo basin is Cetopsis starnesi and in light of the available information we consider the report of Pseudocetopsis gobioides from that river system by Castello (1969) to refer to C. starnesi.

The Neotropical whale catfishes (Siluriformes: Cetopsidae: Cetopsinae), a revisionary study.
Neotropical Ichthyology 3(2):127-238

abstract (from publication):
The catfishes of the subfamily Cetopsinae of the Neotropical family Cetopsidae are revised. Four genera, Cetopsidium new genus, Cetopsis, Denticetopsis, and Paracetopsis Bleeker are recognized as valid.
Bathycetopsis, Hemicetopsis, and Pseudocetopsis are considered synonyms of Cetopsis and Paracetopsis Eigenmann & Bean and Cetopsogiton synonyms of Paracetopsis. Thirty-seven species are recognized in the Cetopsinae.
Cetopsidium includes six species: C. ferreirai, new species, rio Trombetas; C. minutum, Essequibo River; C. morenoi, central and western portions of río Orinoco; C. orientale, coastal rivers of Suriname and French Guiana, and tentatively rio Tocantins and rio Xingu; C. pemon, new species, río Caura, río Caroni, río Meta, and rio Branco; and C. roae, new species, Rupununi River.
Cetopsis includes 21 species: C. amphiloxa río San Juan, río Atrato, and río Patia, western Colombia, and rivers of northwestern Ecuador; C. arcana, new species, rio Tocantins; C. baudoensis, río Baudo; C. caiapo, new species, rio Tocantins; C. candiru, Amazon basin; C. fimbriata, new species, río Truando; C. coecutiens, rio Amazonas, rio Tocantins, and río Orinoco; C. gobioides, upper rio São Francisco, rio Paraná, río Uruguay, and rio Juquiá; C. jurubidae, río Jurubidá; C. montana, new species, western portions of Amazon basin; C. motatanensis, Lago Maracaibo basin; C. oliveirai, Amazon basin; C. orinoco, río Orinoco, río Aroa, and río Yaracuy; C. othonops, río Magdalena and río Sinú; C. parma, western Amazon basin; C. pearsoni, new species, upper portions of rio Madeira; C. plumbea, western portions of rio Amazonas; C. sandrae, new species, rio Tapajós; C. sarcodes, new species, rio Tocantins; C. starnesi, new species, northwestern río de La Plata and southern rio Madeira; and C. umbrosa, new species, western río Orinoco. Cetopsis chalmersi is a synonym of C. gobioides. Cetopsis macroteronema is a synonym of C. plumbea.
Denticetopsis includes seven species: D. epa, new species, rio Tocantins; D. iwokrama, new species, Siparuni River; D. macilenta, Potaro River; D. praecox, río Baria; D. royeroi, upper río Negro; D. sauli, upper río Negro; and D. seducta, new species, western portions of rio Amazonas and río Orinoco.
Paracetopsis consists of three species: P. atahualpa, new species, río Tumbes, northwestern Peru, and río Zarumilla, southwestern Ecuador; P. bleekeri, río Guayas and río Santa Rosa, southwestern Ecuador; and P. esmeraldas, new species, rivers of northwestern Ecuador. Cetopsis ventralis and C. occidentalis are synonyms of Paracetopsis bleekeri.
A neotype is designated for Paracetopsis bleekeri. Lectotypes are designated for Cetopsis candiru, Cetopsis chalmersi, and Cetopsis plumbeus.
