Chaetostoma platyrhynchus is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Caquetá River basin in Colombia. The species reaches 9.5 cm in total length. The species is known to be of disputed classification and spelling.
Panaqolus claustellifer is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Takutu River and the Branco River in Brazil and Guyana. The species reaches 6.2 cm SL. While not described until 2016, it was known to aquarists before its formal description. In the aquarium trade, it is typically referred to either as the blood-red tiger pleco or by one of its two associated L-numbers, which are L-306 and LDA-064. Its specific epithet means "keyhole-bearing" in Latin, referring to the distinctive markings present on the species' snout.
Peckoltia braueri is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the basins of the Rio Negro and the Branco River. It is typically found among large boulders in fast-moving riffles. The species reaches 10.3 cm SL.
Peckoltia capitulata is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Approuague River in French Guiana. It was initially collected from an area of the river with a swift, strong current that was noted to be unusually turbid at the time of collection due to illegal gold mining in the area. The species reaches 7.6 cm SL. Its specific epithet, capitulata, is derived from Latin and reportedly refers to the characteristically small head of the species.
Peckoltia cavatica is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Rupununi basin in Guyana. It is found in areas with large amounts of lateritic rock, and it is usually seen in holes and caves within the rock, which are also where it is thought to breed. P. cavatica's preference for such environments was notable enough to the authors of its 2005 description, Jonathan W. Armbruster and David C. Werneke, that the specific epithet bestowed upon it means "living in caves" in Latin. The species reaches 7.2 cm SL.
Peckoltia compta is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Tapajós basin in Brazil. The species reaches 6.2 cm (2.4 in) SL. It was described in 2010 by Renildo Ribeiro de Oliveira and Jansen Zuanon, Lúcia Rapp Py-Daniel, and Marcelo Salles Rocha primarily on the basis of coloration and patterning. Its specific epithet, compta, is stated to be derived from the Latin word for "adorned" or "ornamented", referring to the species' distinctive color pattern.
Peckoltia lineola is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the basins of the Ventuari River in Venezuela and the Inírida River in Colombia. The species reaches 9.7 cm SL and is typically found in rocky riffles. Its specific epithet, lineola, derives from a Latin word meaning "line", referring to the lines present on the species' compound pterotic.
Peckoltia lujani is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Orinoco and Meta River basins in Venezuela and Colombia. The species reaches 7.5 cm SL.
Peckoltia oligospila is a species of catfish in the family Loricariidae. It is a freshwater fish native to South America, where it occurs in the lower Amazon River basin in Brazil. The species reaches 10.5 cm (4.1 in) SL. It appears in the aquarium trade, where it is typically referred to either by its associated L-number, which is L-006, or as the brown-dot peckoltia.

The species reaches 9.3 cm SL. Its specific epithet, tocantinensis, refers to its type locality, the Tocantins.
Spectracanthicus zuanoni is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Xingu River basin in the state of Pará in Brazil. It is usually found in areas up to 2 m deep with strong currents and rocky substrates, where it is often seen hiding beneath rocks. It is known to occur individually or in groups of three, with juveniles being found alongside other loricariid species, such as Ancistrus ranunculus, Baryancistrus xanthellus, Hopliancistrus tricornis, Parancistrus nudiventris, Peckoltia vittata, and its congener Spectracanthicus punctatissimus.
Hypostomus mutucae is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Cuiabá River basin in Brazil. The species reaches 10.9 cm SL.
Hypostomus nigromaculatus is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the middle and upper Paraná River basin in Brazil. The species reaches 10.2 cm in standard length and is believed to be a facultative air-breather.
Hypostomus peckoltoides is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Cuiabá River in the upper Paraguay River basin in Brazil. It is typically found in environments with turbid water, a substrate composed of rocks and sand, and various types of riparian vegetation. It is known to be syntopic with other species of Hypostomus, including H. boulengeri, H. cochliodon, H. latifrons, H. latirostris, and H. regani.
Hypostomus plecostomoides is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Meta River basin in Colombia. The species reaches 25.6 cm in total length and is believed to be a facultative air-breather. Its specific epithet, plecostomoides, may refer to perceived similarity between it and the species Hypostomus plecostomus, which it does not overlap with in distribution, although it may also refer to the now-invalid genus Plecostomus.
Ancistomus feldbergae is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Xingu River basin in Brazil.
Ancistomus snethlageae is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Tapajós basin in Brazil. The species reaches 22 cm (8.7 in) in total length. Although originally described as a species of Ancistrus in 1911 by Franz Steindachner and subsequently reclassified in the genera Hemiancistrus, Lasiancistrus, and Peckoltia, a 2015 review conducted by Jonathan W. Armbruster, David C. Werneke, and Milton Tan listed the species as valid within Ancistomus.
