A new species of Rineloricaria (Siluriformes: Loricariidae: Loricariinae) from rio Daraá, rio Negro basin, Amazon, Brazil

Abstract

Rineloricaria daraha, new species, is described from the rio Daraá, tributary of rio Negro, northwestern Amazonas State, Brazil. The new species is diagnosed by having seven branched pectoral-fin rays, finger-like papillae on the lower lip, a large multi-angular preanal plate, and at least four quadrangular plates of variable size surrounding the preanal plate. The new species is known only from rio Daraá and its waterfalls.Rineloricaria daraha, espécie nova, é descrita do rio Daraá, um afluente do rio Negro, noroeste do Estado do Amazonas, Brasil. A nova espécie pode ser diagnosticada por apresentar sete raios ramificados na nadadeira peitoral, lábios inferiores com papilas digitiformes, uma grande placa pré-anal multi-angular e, pelo menos, quatro placas de diferentes tamanhos circundando a placa pré-anal. A nova espécie é conhecida apenas do rio Daraá e suas cachoeiras.

Intergeneric phylogenetic relationships in catfishes of the Loricariinae (Siluriformes: Loricariidae), with the description of Fonchiiloricaria nanodon: a new genus and species from Peru

“…The general shape of the mouth of Fonchiiloricaria is similar to that of species of Rineloricaria and Ixinandria steinbachi (Regan 1906) and the presence of digitiform papillae of different degrees of development on the mouth, also occurs in Rineloricaria daraha Rapp Py- Daniel & Fichberg 2008, Rineloricaria heteroptera Isbrücker & Nijssen 1976, Metaloricaria paucidens Isbrücker 1975 and Spatuloricaria sp.…”

“…Within the Loricariidae, members of the subfamily Loricariinae are united by a long and depressed caudal peduncle and by the absence of an adipose fin, but they exhibit substantial variation in body shape, lip morphology and dentition. There are currently 220 valid species of Loricariinae, distributed in 30 genera (Covain & Fisch-Muller, 2007;Fichberg & Chamon, 2008;Ghazzi, 2008;Ingenito et al, 2008;Rapp Py-Daniel & Fichberg, 2008;Rodriguez & Miquelarena, 2008;Thomas & Rapp Py-Daniel, 2008;de Carvalho Paixão & Toledo-Piza, 2009;Thomas & Sabaj Pérez, 2010).…”

Systematics of Lamontichthys Miranda-Ribeiro (Siluriformes: Loricariidae), with the description of two new species

“…Harttia leiopleura Oyakawa and Rineloricaria daraha Rapp Py-Daniel & Fichberg also possess seven branched pectoral-fin rays. Species of Lamontichthys can be distinguished from Harttia leiopleura by the presence of dermal plates on the upper lip and lateroventral plates on the thoracic region (vs. absent; Oyakawa, 1993) and from Rineloricaria daraha by having button-like papillae on the ventral surface on the lower lip (vs. long digitiform papillae), the lack of a postorbital notch and by having 14 caudal-fin rays (vs. 12;Rapp Py Daniel & Fichberg, 2008). Five other characters observed only in skeletal preparations and detailed under "Character analysis and description" further distinguish Lamontichthys from other loricariids: 1) the trapezoidal shape of the lower pharyngeal plate, with the medial and lateral borders almost parallel, the medial border larger than the posterior border and at least twice as large as the lateral border (character 13); 2) the triangular and relatively elongate posterior expansion of the first epibranchial (character 14); 3) the large coronoid process in the dentary (character 23); 4) the contact (or proximity) between the proximal portions of the first three anal-fin pterygiophores (character 69); 5) the presence of two broad apophysis on the second preural centrum (character 77).…”

Taxonomic revision of the Rineloricaria species (Siluriformes: Loricariidae) from the Paraguay River basin

“…The genus Rineloricaria Bleeker, 1862 actually comprises 65 valid species (Ferraris, 2007;Ghazzi, 2008;Ingenito et al, 2008;Rapp Py-Daniel & Fichberg, 2008;Rodriguez & Miquelarena, 2008;. Species of this genus exhibit an extensive variation in their body sizes, color pattern, arrangement of abdominal plates, shape of the head, form, and placement of their sexually dimorphic odontodes.…”

“…However, Isbrücker et al (2001) Isbrücker & Nijssen, 1976). This arrangement was partially accepted by some authors (Ferraris, 2007;Rodriguez & Miquelarena, 2008;Ingenito et al, 2008) and rejected by others (Ferraris, 2003;Covain & Fisch-Muller, 2007;Rapp Py-Daniel & Fichberg, 2008;. There is not a consensus whether to accept or not the splitting of Rineloricaria in more groups, in consequence we decided to use the arrangement summarized in Ferraris (2003) until a classification based on cladistic approaches be formally published for this group.…”
