Exastilithoxus is a small genus of suckermouth armored catfish native to South America.
There are currently two recognized species in this genus: [1]
Exastilithoxus species are small, cylindrical loricariids. [2]
These species exhibit a round lower lip with fleshy barbels. [2] Color pattern is generally mottled and dark brown with paler areas under and just posterior to the dorsal fin. The abdomen is white, fins are mottled, and the ventral surface of the caudal peduncle is colored as the sides, but slightly lighter. [2] Like other loricariids, the body is armored, however the abdomen is naked. [2]
Exastilithoxus species are unique among loricariids in that they subsist entirely on insect larvae. [2]
Ancistrus is a genus of nocturnal freshwater fish in the family Loricariidae of order Siluriformes, native to freshwater habitats in South America and Panama. Fish of this genus are common in the aquarium trade where they are known as bushynose or bristlenose catfish. In the aquarium hobby they are often referred to as bushynose or bristlenose plecos instead, but this may lead to confusion as "pleco" usually is used for Hypostomus plecostomus and its allies and is often used as a catchall term for any loricariids remotely resembling that species.
Pseudorinelepis genibarbis is a species of armored catfish native to Brazil and Peru where it is found in the Amazon basin.
Acanthicus is a genus of large, South American suckermouth armored catfishes native to the Amazon and Orinoco basins, and possibly in Guyana. The name Acanthicus is derived from the Greek, akanthikos meaning thorny, spiny. Fish of this genus are known as lyre-tail plecos. These species are found in large rivers, primarily in areas with a rocky bottom and a moderate or strong current.
Apistoloricaria is a genus of armored catfishes native to South America.
Pseudancistrus is a genus of suckermouth armored catfishes native to South America.
Rineloricaria is a genus of freshwater tropical catfish belonging to the family Loricariidae. They are commonly called whiptail catfish because of the long filament that grows out of the tip of the caudal fin that is characteristic of the genus. With the exception of R. altipinnis from Panama, they are native to the rivers of northern and central South America. Some species are regularly seen in the aquarium trade.
Hypancistrus is a genus of loricariid catfish originating from the Amazon basin in South America. Unlike many of the other Loricariids, however, some Hypancistrus species are more carnivorous and enjoy meat in their diet. Hypancistrus species are popular aquarium fish, including such popular fish as the zebra pleco and Queen Arabesque pleco.
Peckoltia is a genus of small South American armored suckermouth catfishes. Many of these fish are popular aquarium fish.
Corymbophanes is a genus of armored catfish native to South America where they are only known from Guyana. Corymbophanes was originally placed in its own tribe Corymbophanini, but the first comprehensive molecular phylogenetic analysis of the subfamily Hypostominae found Corymbophanes to be nested within the tribe Ancistrini.
Pogonopoma is a genus of armored catfish native to rivers in south and southeast Brazil.
Rhinelepis is a genus of South American armored catfish.
Spectracanthicus is a genus of suckermouth armored catfish endemic to the Tapajós, Xingu and Tocantins river basins in Brazil where often found in fast-flowing waters. The largest species in the genus reaches up to 13 cm (5.1 in) in standard length. They feed on algae and small invertebrates.
Neblinichthys is a small genus of suckermouth armored catfishes native to South America.
Lamontichthys is a genus of armored catfishes native to South America.
Pseudohemiodon is a genus of armored catfishes native to South America.
Lithoxus is a genus of suckermouth armored catfishes native to tropical South America.
Leporacanthicus is a genus of suckermouth armored catfishes native to South America.
Pseudolithoxus is a genus of suckermouth armored catfishes with five described species from the basins of the Orinoco, Casiquiare and upper Rio Negro in Venezuela. Additionally, a possibly undescribed species is known from the Trombetas and Nhamundá rivers in Brazil.
Guyanancistrus is a genus of suckermouth armored catfishes.
Scobinancistrus is a genus of armored catfishes native to the southeastern Amazon in Brazil. They are black with numerous white to orange spots, and the fins can have broad reddish-orange edging. They reach up to 27–29 cm (10.6–11.4 in) in length.
