Ancistrus mattogrossensis [1] is a species of catfish in the family Loricariidae. It is a freshwater species native to South America, where it is known only from Brazil. [2]
Ancistrus hoplogenys is a species of armored catfish native to Argentina, Brazil, Guyana, Paraguay, Peru, and Uruguay, where it occurs in the basins of the Amazon River, the Essequibo River, and the Paraguay River. It has also been reported from Suriname. This species grows to a length of 15.8 centimetres (6.2 in) SL. In the aquarium hobby, this fish is sometimes known as the spotted or starlight bristlenose pleco, although it may also be referred to by its L-number, which is L059.
Ancistrus caucanus is a species of catfish in the family Loricariidae. It is native to South America, where it was at one point thought to occur in the Cauca River basin in Colombia, for which it is named, although subsequent research suggested in 2013 that it is actually native to the Magdalena River basin, whereas its congener Ancistrus vericaucanus is the species native to the Cauca. The species reaches 5.2 cm SL. It is not to be confused with the similarly named species Lasiancistrus caucanus.
Ancistrus bolivianus is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the basins of the Beni River, the Mamoré River, and the Madre de Dios River. The species reaches 8.8 cm SL.

It is a stygobitic species that is known to lack eyes and body pigmentation, which indicate a high level of specialization to living in a subterranean, lightless environment. It is one of three known stygobitic members of Ancistrus, alongside A. cryptophthalmus and A. galani. The species reaches 7.9 cm SL.

Ancistrus trinitatis is a dubious species of catfish in the family Loricariidae. It is known only from the Caribbean, where it occurs in freshwater environments on the island of Trinidad in Trinidad and Tobago. This species is of uncertain validity, as Theodore Gill referred to the type material in 1858 as Ancistrus guacharote and it was later described by Albert Günther in 1864 as Chaetostomus trinitatis, but neither description is considered sufficient to determine the validity and identity of the taxon. While the original locality of the type material was listed as Puerto Rico, this was determined to be in error and the material was determined to have actually originated from the Maracaibo Basin of Venezuela. In 1946, Henry Weed Fowler described the species Ancistrus maracasae from Trinidad, and in 2019, Lesley S. De Souza, Donald C. Taphorn, and Jonathan W. Armbruster determined that A. maracasae and A. trinitatis are synonymous, designating the holotype of A. maracasae as the neotype of A. trinitatis, although sources such as FishBase and ITIS list the two species as valid but separate.
