  author={Norma Salcedo},
A new genus and species of armored catfish, Loraxichthys lexa, collected in 1955 by the Catherwood Foundation Peruvian-Amazon Expedition from the vicinity of Tingo María, Huánuco, is described herein. Loraxichthys is diagnosed by two uniquely derived characters: two to four robust evertible posterior cheek odontodes with hooked tips, longer than odontodes anterior to them but no more than twice their length; and skin folds on dorsal border along first pelvic-fin ray crenulated in mature males…

A new species of Chaetostoma, an armored catfish (Siluriformes: Loricariidae), from the río Marañón drainage, Amazon basin, Peru
A new species of Chaetostoma was found in mountain tributaries of the rio Maranon, Peru, which resembles two Cordylancistrus species in the presence of a tuft of odontodes in the middle of each trunk lateral dermal plate, but it exhibits a naked snout.
Two New Chaetostoma Group (Loricariidae: Hypostominae) Sister Genera from Opposite Sides of the Andes Mountains in Ecuador, with the Description of One New Species
The hypothesis that these genera may have once been contiguously distributed through a low-lying region of northern Peru and been separated via uplift of the Andes Mountains is supported.
A Multilocus Molecular Phylogeny for Chaetostoma Clade Genera and Species with a Review of Chaetostoma (Siluriformes: Loricariidae) from the Central Andes
A five-locus molecular phylogeny for 21 described and six undescribed species of Chaetostoma spanning the geographic range of the genus and a systematic review of species from the central Andes of northern Peru and Ecuador is conducted.


Intergeneric phylogenetic relationships in catfishes of the Loricariinae (Siluriformes: Loricariidae), with the description of Fonchiiloricaria nanodon: a new genus and species from Peru.
This species is described as a new genus and new species of Loricariinae: Fonchiiloricaria nanodon, which is diagnosed by usually possessing one to three premaxillary teeth that are greatly reduced.
Review of the andean armored catfishes of the genus Dolichancistrus Isbrücker (Siluriformes: Loricariidae)
The loricariid catfish genus Dolichancistrus is reviewed and four species recognized, and a key is provided to the members of the genus, and diagnoses and redescriptions are provided for all of the recognized species.
A New Genus and Species of Weakly Armored Catfish from the Upper Mazaruni River, Guyana (Siluriformes: Loricariidae)
The opercle of Paulasquama is sickle-shaped as in basal ancistrins, but has a posterior connection to the hyomandibula as in derived members of the Ancistrus clade.
New Species of Chaetostoma (Siluriformes: Loricariidae) from Central Peru
This new species differs from all other described Chaetostoma species in having a conspicuously banded dorsal fin and by the combination of the following characters: presence of fleshy excrescence on posterior tip of supraoccipital, typically nine branched dorsal-fin rays, and evertible cheek plates with two to four hypertrophied odontodes.
The genus Peckoltia with the description of two new species and a reanalysis of the phylogeny of the genera of the Hypostominae (Siluriformes: Loricariidae)
A revised morphological phylogeny demonstrates the lack of support for Peckoltia and Hemiancistrus as monophyletic, and phenetic definitions are provided for the two genera.
Checklist of catfishes, recent and fossil (Osteichthyes: Siluriformes), and catalogue of siluriform primary types
A checklist of Recent and fossil catfishes (Order Siluriformes) is presented, summarizing taxonomic literature published through 2005, and one new name is proposed herein: Clariallabes teugelsi, as a replacement for Clarias (Allabenchelys) dumerili longibarbis David & Poll, 1937.
The Fitzcarrald Arch: A Vicariant Event for Chaetostoma (Siluriformes: Loricariidae) Speciation?
It is concluded that there are not significant differences among populations of C. lineopunctatum from the Río Ucayali and theRío Madre de Dios drainages, and thus the Fitzcarrald Arch uplift did not cause speciation in this taxon.
Phylogenetic relationships of the suckermouth armoured catfishes (Loricariidae) with emphasis on the Hypostominae and the Ancistrinae
A phylogenetic analysis of nearly all genera of the Hypostominae and the Ancistrinae is provided based on osteology, external anatomy, and digestive tract anatomy. The results suggest that the
Osteology of Hypostomus plecostomus (Linnaeus), with a phylogenetic analysis of the loricariid subfamilies (Pisces: Siluroidei)
A new species of Pseudacanthicus is described from the Rio Xingu basin, distinguished from its congeners by the following combination of characters: presence of anastomose dark blotches forming
New Endemic Species of Anthurium (Araceae) from Río Huallaga, Peru
Ten new species of Anthurium (Araceae) are described from Amazonian Peru, nine of which are endemic to a single area of high endemism in the southern Huallaga River Valley of Huánuco Department and the area between Tingo María and La Divisora.
