A new tiny-spotted species of Hypostomus (Siluriformes: Loricariidae) from the upper Rio Tocantins basin, Gois State, Brazil.

Scientific visits to ichthyological collections revealed a potentially new species of Hypostomus from the Rio Tocantins basin. From there, subsequent ichthyological surveys led us to capture the taxon in the upper portion of this basin and address it to the H. punctatus group.

Catalog of type specimens of the fish collection of the Ncleo de Pesquisas em Limnologia, Ictiologia e Aquicultura (NUP), Universidade Estadual de Maring, Paran, Brazil.

This study aims to provide an annotated list of the type-material housed in the fish collection of the Ncleo de Pesquisas em Limnologia, Ictiologia e Aquicultura (NUP), Universidade Estadual de Maring, Paran, Brazil. NUPs fish type collection hosts type-material of 157 species, distributed in 503 lots (11 holotypes and 492 lots of paratypes) totalling 2,915 specimens. For each species, catalog numbers of all available lots are provided, and for each lot, total number of specimens, range of variation of standard length, number of cleared and stained specimens (when any), locality data, collectors, and date of collection, are provided.

Assessing two hundred years of taxonomic doubt with the rediscovery and taxonomic establishment of the Amazonian armored catfish Hypostomus pantherinus Kner 1854 (Siluriformes: Loricariidae).

Hypostomus pantherinus was described by Kner in 1854 based on a single young specimen collected by Natterer with a type-locality just asserted as Guapor. No robust scientific paper focusing the distribution, taxonomy and ecology of this species has been published since the description. Here, based on the analysis of the holotype, recently collected material, and on an extensive searching on ichthyological fish collections, H.
