Lamontichthys is a genus of armored catfishes native to South America.
The phylogenetic position of Lamontichthys remains uncertain. It has been considered to be sister to Harttia , whereas Lamontichthys shows much more similarities with Pterosturisoma microps of the monotypic genus Pterosturisoma , which only differs from Lamontichthys by the number of pectoral fin rays. [1]
There are currently six recognized species in this genus: [2]
Lamontichthys is distributed in the northwestern part of South America in the upper Amazon and Orinoco River drainages, and in the Lake Maracaibo region. Species in this genus occupy the same ecological niche as those of Harttia. They mainly live in the mainstream of rivers, on rocky and sandy bottoms. [1]
Sexual dimorphism in Lamontichthys includes hypertrophied odontodes on the pectoral spines in mature males. [1] In all species of Lamontichthys, there is one pectoral fin spine and seven pectoral fin rays on each fin, as opposed to the rest of Loricariinae species which have one pectoral fin spine and only six pectoral fin rays. [1]
Lamontichthys is an open brooder; eggs are laid on an open surface such as rocks, submerged wood or plants, and are generally exposed to the current. Females lay a few large-sized (1.4–1.8 millimetres or .056–.071 in in diameter) yellowish eggs during each spawning event. [1]
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.
Loricariidae is the largest family of catfish, with 92 genera and just over 680 species. Loricariids originate from freshwater habitats of Costa Rica, Panama, and tropical and subtropical South America. These fish are noted for the bony plates covering their bodies and their suckermouths. Several genera are sold as "plecos", notably the suckermouth catfish, Hypostomus plecostomus, and are popular as aquarium fish.
The Doradidae are a family of catfishes also known as thorny catfishes, raphael catfishes or talking catfishes. These fish are native to South America, primarily the Amazon basin and the Guianas.
Apistoloricaria is a genus of 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.
Hemiancistrus is a genus of suckermouth armored catfishes. These species are native to South America. The taxonomy of this genus is complex and unclear, and major work has to be done. Many of these fish are popular aquarium fish.
Loricariinae is a subfamily of the family Loricariidae of catfish. This subfamily is divided into two tribes and about 30 genera. They are mainly native to freshwater habitats in South America, but there are also several species in Panama and a single (Fonchiiichthys) in Costa Rica.
Harttiella crassicauda is a species of armored catfish.
Pterosturisoma microps is the only species of the monotypic genus Pterosturisoma, a genus of the family Loricariidae of catfish.
Neblinichthys is a small genus of suckermouth armored catfishes native to South America.
Ixinandria steinbachi is the only species in the genus Ixinandria of catfish of the family Loricariidae.
Harttia is a genus of armored catfishes native to South America.
Loricaria is a genus of armored catfish native to South America.
Metaloricaria is a genus of armored catfishes native to South America.
Dasyloricaria is a genus of armored catfishes native to Central and South America. The distribution of these species includes the northwestern South America on the Pacific slope of Colombia and Panama. Its distribution is restricted to the Pacific slope of the Andes, which is a unique pattern of distribution within the subfamily.
Pseudohemiodon is a genus of armored catfishes native to South America.
Spatuloricaria is a genus of armored catfishes native to South America and Panama.
Hemiodontichthys is a monotypic genus in the family Loricariidae, under the order Siluriformes, containing a single species, Hemiodontichthys acipenserinus, also known as the Pinocchio whiptail catfish, Pinocchio catfish, Pinocchio cat or the knob-nosed whiptail. This shy, bottom-dwelling catfish is native to the Guianas, Brazil, Bolivia and Perú in South America.
Hoplomyzon is a genus of banjo catfishes that are native to tropical South America.
Lamontichthys avacanoeiro is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the upper Tocantins River basin in Brazil. The species reaches 16 centimetres (6.3 in) in standard length. Its specific name, avacanoeiro, refers to the Avá-Canoeiro people, speakers of the Avá-Canoeiro language, who inhabit the upper Tocantins basin.
