Tetragonopterus gibbosus Steindachner, 1877 : 562 , pl. 1 (original description; type locality: “Rio Parahyba [Parnaíba] Brazil). Diagnosis. Tetragonopterus chalceus is distinguished from T. anostomus , T. denticulatus , T. juruena , and T. kuluene by the presence of 4 principal teeth on dentary ( vs. 5–6), and by having larger and more robust teeth ( vs. thinner and sharper teeth). Tetragonopterus chalceus differs from T. anostomus and T. araguaiensis by having 11–14 gill-rakers on lower limb of the first gill arch ( vs. 17–20). Tetragonopterus chalceus differs from T. carvalhoi by the presence of a rounded dark mark on the caudal peduncle ( vs. lozenge-shaped dark mark on caudal peduncle). Tetragonopterus chalceus differs from T. anostomus by having a terminal mouth ( vs. subsuperior mouth) and from T. anostomus and T. kuluene by having two conspicuous humeral marks ( vs. only one humeral mark). Tetragonopterus chalceus differs from T. argenteus by having 7–9 predorsal scales ( vs. 11–17); it also differs from T. franciscoensis by the presence of 20–40 olfactory lamellae ( vs. 11–17) and by having more robust teeth on dentary ( vs. thinner and sharper teeth). Tetragonopterus chalceus differs from T. denticulatus by having humeral marks separated by a single vertical scale row ( vs. humeral marks separated by three vertical scale rows). Tetragonopterus chalceus differs from T. rarus by the lack of longitudinal dark stripes on the trunk ( vs. presence of such stripes); it differs from both T. rarus and T. georgiae by having 3.5 scale rows between lateral line and pelvicfin origin ( vs. 4.5–5.5). Finally, T. chalceus differs from T. ommatus by having 1–4 teeth on the maxilla ( vs. 7–8) and by the presence of a conspicuous dark mark on the caudal peduncle ( vs. inconspicuous mark limited to the posterior portion of the caudal peduncle).

Tetragonopterus chalceus is distributed in the Amazon basin (including rio Tocantins ), Orinoco and the Atlantic drainages of the Guianas such as the Essequibo , Corantijn and Marowijne river basins ( Fig. 2 b). Remarks. Tetragonopterus chalceus was described by Agassiz, in Spix & Agassiz (1829) based on material collected during the expedition of Martius and Spix to Brazil ( 1817 to 1820 ), which explored the São Francisco and the Amazon river basins ( Kottelat 1988 ). Therefore, the potential holotype of T. chalceus (MHNN 785), as implied by Jacques Géry (see Kottelat 1988 ) was, thus, provenient from one of the two aforementioned basins. Agassiz (1829) mentioned T. chalceus ’s type locality simply as Habitat in Brasiliae aequinociales (habitat in equinoctial Brazil). Considering the additional species described from equinoctial Brazil [ e.g. Hypophtalmus edentatus , Hypophtalmus nuchalis (= Auchenipterus nuchalis ), Cetopsis candiru, Anodus latior (= Potamorhina latior ), Leporinus novemfasiatus (= Leporinus fasciatus ), Pimelodus pirinampu (= Pinirampus pirinampu ), Pimelodus ctenodus (= Calophysus macropterus ), Platystoma planiceps (= Sorubimichthys planiceps ), Platystoma truncatum (= Pseudoplatystoma tigrinum ), Serrasalmus aureus (= Pristobrycon aureus ), Serrasalmus nigricans , Myletes aureus (= Mylossoma aureum )], it is clear that it corresponds to the Amazon basin. Likewise, Agassiz’s species from “Habitat in fluvial S. Francisci [ e.g. Rhinelepis aspera , Pimelodus rigidus , Platystoma corruscans (= Pseudoplatystoma corruscans ), Prochilodus argenteus and Serrasalmus piranha (= Pygocentrus piraya )], or Habitat in Brasiliae septentrionalis fluviis [ e.g. Hypostoma etentaculatum (= Pterygoplichthys etentaculatus )] correspond unequivocally to the Rio São Francisco basin.
