can be found in the main channel of rivers, in moderate to strong currents, in shallow to deep habitats, and are usually collected at 2 to 3 meters in depth, hiding below conglomerate plates of rocks and gravel, or among medium to large bedrocks. In captivity, the species is omnivorous and detritivorous and usually feeds by scraping small particles from the substrate. Mature males usually develop more extensive and shaply odontodes on the pectoral spine, opercle and cheeks; they can also be more aggressive and exhibit territorial behavior (information about feeding and sexual dimorphism from www.seriouslyfish.com).

Most of these characters are external morphological features that diagnose the genus. Additional features are herein proposed as diagnostic for the genus, namely: (1) an enlarged and fenestrated compound pterotic associated to the distention of the posterior process of the Weberian apparatus, (2) an enlarged swim bladder capsule, extending beyond the sixth rib; (3) snout completely covered by plates; (4) the presence of abdominal plates; and (5) pectoral-fin spine, when adpressed, reaching almost the end of the unbranched pelvic-fin ray.

, the reduction and consequent encapsulation of the swim bladder has occurred as an adaptation to a bottom-dwelling life style, and the importance of the Weberian apparatus has probably prevented the complete loss of the swim bladder. Furthermore, in groups with aerial respiratory organs, it is possible that the reduction of the swim bladder was in compensation of the hydrostatic effect of the accessory respiratory organs (Alexander, 1964; 1966). More recently, Lechner &amp; Ladich (2008) correlated the morphology of the swim bladder with hearing ability, and suggested that reduced and encapsulated swim bladders do not affect hearing in low frequencies. The authors also indicated that in taxa among the

According to the International Code of Zoological Nomenclature, “the fact that the holotype specimen no longer exists or cannot be traced does not of itself invalidate the original designation” (ICZN, article 74.1.3). Aiming taxonomical stability, it is best to recognize the species and further support its validity through a comprehensive description than to make a small change in the taxonomy of the group by the unnecessary designation of a neotype.

The authorship of many species described in Spix &amp; Aggasiz, 1829 has generated controversy in the literature. Historically, species authorships were generally considered to belong to Spix (Günther, 1868b; Eigenmann &amp; Eigenmann, 1889; Regan, 1904; Fowler, 1954; Isbrücker, 1980), or more recently to Spix and Agassiz (Fisch- Muller, 2003; Ferraris, 2007). Spix and Agassizs “Selecta genera et species piscium quos in itinere per Brasiliam annos MDCCCXVII-MDCCCXX” was published in two fascicles, the first one in 1829 and the second in 1831;

was described in the first one. According to Kottelat (1988), Spix collected the specimens and supervised the execution of the drawings, while Agassiz arranged the species in the systematic order and prepared the anatomical plates. Most plates of the first fascicle were engraved and colored before Spixs death, and carry the names that Spix intended to give them, but Agassiz did not follow Spix's ideas in several cases when he judged that some names were inappropriate or misidentifications. Thus, Agassiz is the unique author of the species name in that case, including
