Review of the andean armored catfishes of the genus Dolichancistrus Isbrücker (Siluriformes: Loricariidae)

  author={Gustavo A. Ballen and Richard P. Vari},
  journal={Neotropical Ichthyology},
The loricariid catfish genus Dolichancistrus is reviewed and four species recognized. Species of Dolichancistrus are distinguished from each other by the degree of development of the pectoral-fin spine, the form of the distal margin of the pelvic fin, the relative size and form of the cheek plates, the pattern of odontodes along the margin of the snout, the presence versus absence of a buccal papilla at the premaxillary symphysis, and the relative lengths of the anal- versus pelvic-spines…

Description of Loraxichthys lexa, new genus and species (Siluriformes: Loricariidae) from the Río Huallaga Basin, central Peru, with notes on the morphology of the enigmatic Lipopterichthys carrioni Norman, 1935.
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
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.
Biogeography and species delimitation of the rheophilic suckermouth catfish genus Pseudolithoxus (Siluriformes: Loricariidae), with the description of a new species from the Brazilian Amazon
The data reject a simple model of Miocene vicariance in the group following uplift of the Uaupés Arch separating the Orinoco and Amazon systems, and instead suggest more complex dispersal scenarios through palaeo-connections in the Pliocene and also via the contemporary rio Negro and rio Madeira in the late Pleistocene.
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.
A fossil fish assemblage from the middle Miocene of the Cocinetas Basin, northern Colombia
There is a continental-wide structuring of the Miocene fish faunas that is also found in the extant fauna, suggesting that other factors such as ecological conditions, in addition to the uplift of the Andes, have shaped the biogeographic evolution of South American fish faunaas.
A fossil fish assemblage from the middle Miocene of the Cocinetas Basin, northern Colombia
Freshwater fossil fish faunas have long been used to infer past drainage connections, given that they are bounded by physical freshwater barriers. Here we study a middle Miocene (15.0–15.5 Ma)
Description of Neblinichthys peniculatus, a new species of loricariid catfish from the río Paragua drainage of Venezuela
Se describe una nueva especie, Neblinichthys peniculatus, con especimenes colectados del rio Carapo (cuenca del rio Paragua-rio Caroni), que drena el flanco sur del Cerro Guaiquinima en el sureste de
Checklist of the freshwater fishes of Colombia: a Darwin Core alternative to the updating problem
Updating the current checklist is a fundamental requirement to ensure its incorporation in the decision-making process with regard to the conservation of Colombian aquatic species and ecosystems, which are facing transformation processes as a result of activities such as mining, construction of hydroelectric plants, expansion of the agricultural frontier and subsequent deforestation.

Pseudancistrus sidereus, a new species from southern Venezuela (Siluriformes: Loricariidae) with a redescription of Pseudancistrus
Pseudancistrus sidereus is described from two collections of specimens from Amazonas, Venezuela and is diagnosed by the following synapomorphies: no suture between pterotic-supracleithrum and hyomandibula, no contact of the hyom andibula with the prootic, straight, spoon-shaped anterior process of metapterygoid.
Cordylancistrus nephelion (Siluriformes, Loricariidae), a new and endangered species of suckermouth armored catfish from the Tuy River, north-central Venezuela
A new species of suckermouth armored catfish, Cordylancistrus nephelion, is described from seven specimens collected in tributaries of the Tuy River in the Caribbean Sea basin of north-central
Two New Genera and Species of Ancistrini (Siluriformes: Loricariidae) from the Western Guiana Shield
Two new ancistrin genera and species are described from main channels and tributaries of the upper Orinoco River in Amazonas, Venezuela, distinguished by its small body-size, large gas-bladder capsules, and highly protrusible mandibles.
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
A New Black Baryancistrus with Blue Sheen from the Upper Orinoco (Siluriformes: Loricariidae)
Abstract Baryancistrus beggini, new species, is described from the upper Río Orinoco and lower portions of its tributaries, the Río Guaviare in Colombia and Río Ventuari in Venezuela. Baryancistrus
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.
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.
Peckoltia sabaji, a new species from the Guyana Shield (Siluriformes: Loricariidae)
Peckoltia sabaji is described based on specimens from the Guyana Shield regions of the Essequibo, Negro, and Orinoco River drainages of Guyana and Venezuela. Peckoltia sabaji is a member of the
Four New Hypancistrus (Siluriformes: Loricariidae) from Amazonas, Venezuela
Hypancistrus contradens and H. lunaorum differ from H. inspector by having the dorsal fin reaching the adipose fin when adpressed, having spots on the head the same size as the body or spots absent (vs. spots smaller on head) and by usually having 22–23 mid-ventral plates.
