Última Taxonomic revision and phylogenetic relationships of Dasyloricaria Isbrücker & Nijssen, 1979 (Siluriformes: Loricariidae), with description of a new species Neotropical Ichthyology Londoño-Burbano,Alejandro; Reis,Roberto E.. ABSTRACT A taxonomic revision and phylogenetic analysis were completed for Dasyloricaria . The genus includes three valid species: D . filamentosa and D . latiura previously included in the genus, and a new species described herein. Dasyloricaria have a restricted trans-Andean distribution, with D . filamentosa occurring at the lower and middle Magdalena, lower Cauca, and Sinu in Colombia, and lago Maracaibo basin in Colombia and Venezuela; D . latiura in the Atrato and the Tuyra basins in Colombia and Panama, respectively; and the new species in the upper and middle Magdalena basin in Colombia. New synonyms for D . filamentosa and D . latiura are proposed, and a lectotype is designated for the latter. Dasyloricaria is herein recognized as monophyletic,...

ABSTRACT Otoliths are three pairs of calcareous structures found in the inner ear of bony fish. In many cases they display a species-specific morphology. The present study describes morphological variations of otoliths, namely lapillus, asteriscus and sagitta, of eleven species belonging to four loricariid subfamilies. Otolith structures that characterize the Loricariidae and some of its subfamilies are presented. The sagitta exhibit a specific morphology that is not found in other siluriform families; it is claviform with a tapered posterior region and a flared anterior one. In the latter, central elevations are observed and the dorsal wings are continuous with lateral expansions named basal wings. Hypoptopomatinae and Loricariinae as well as Hypostominae...

Ano: 2017 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252017000100202 Habitat use by two species of Hypostomus (Pisces, Loricariidae) in southeastern brazilian streams Biota Neotropica Casatti,Lilian; Rocha,Fabíola C.; Pereira,Danusa C.. In this study, habitat use of the armored catfishes Hypostomus ancistroides and Hypostomus sp. was investigated in 21 streams from the Upper Rio Paraná system in São Paulo State, Brazil, a pasture dominated region. The abundance of Hypostomus sp. was positively correlated with the amount of riffles and riparian vegetation condition, whereas H. ancistroides abundance was negatively correlated with riparian vegetation condition. Thirteen ecomorphological attributes analyzed by principal component analysis showed that when compared to H. ancistroides, Hypostomus sp. presented a wider mouth and more flattened body, suggesting an adapted body to faster waters. The most abundant populations of Hypostomus sp. were predominantly associated with good riffle...
