Pseudomystus is a genus of catfishes (order Siluriformes) of the family Bagridae.
Pseudomystus was originally described by Jayaram in 1968 as a subgenus to Leiocassis . It was elevated to genus rank in 1991 by Mo. There is evidence to indicate that these two genera are not even closely related. [1] There is the possibility that Pseudomystus as currently understood may not be monophyletic. [2]
P. carnosus, P. fumosus and P. moeschii are hypothesized to form a monophyletic group. [2]
However, Pseudomystus has been treated in some recent literature as a synonym of Leiocassis. [3]
There are currently 19 described species in this genus: [4]
Pseudomystus species inhabit swamps, streams and rivers throughout Southeast Asia. [2] The genus is distributed in Thailand, Vietnam, Malaysia, and Indonesia, on Java, Sumatra, and Borneo, with only P. siamensis and P. bomboides known from north of the Thai Peninsula. The greatest number of species is found in Borneo (about ten species), followed by Sumatra (about seven). [1]
Pseudomystus species are small- to mid-sized bagrid catfishes. [2]
Many Pseudomystus species are beautiful fishes with colour patterns of striking contrast, with light bands and/or blotches on a dark background on the body and fins, with the pattern reversed on some fins in some species. [1] This coloration leads them to be known as bumblebee catfish in the aquarium trade. [2] Some species were described to have a uniform colour have a banded colouration when juvenile. P. stenogrammus and P. mahakamensis lack any blotches or bands on the body, instead possessing a clearly defined midlateral stripe on a dark background; this stripe is thinner in P. stenogrammus. [1]
All Pseudomystus can be sexed in the typical bagrid fashion (by the presence of a genital papilla in males) and the males' genital papilla is even more distinct than in many other bagrids. [5]
The genus Pseudomystus includes a number of ornamental species kept in the fishkeeping hobby, in which they are commonly called bumblebee catfish or false bumblebee catfish. These nocturnal fish may disappear into an aquarium for months. These catfish can consume smaller tankmates. They do well in a community set-up. However, as they are territorial each individual will need its own cave; damaged tails due to territorial disputes is a sign there are not enough retreats. They are highly adaptable and can live in almost any water condition (though extremes should be avoided). There have been no known spawnings in captivity. [5]
Clarias is a genus of catfishes of the family Clariidae, the airbreathing catfishes. The name is derived from the Greek chlaros, which means lively, in reference to the ability of the fish to live for a long time out of water.
The stream catfishes comprise the family Akysidae of catfishes.
The Bagridae are a family of catfish that are native to Africa (Bagrus) and Asia from Japan to Borneo. It includes about 245 species. These fish are commonly known as naked catfishes or bagrid catfishes.
Oreoglanis is a genus of fish in the family Sisoridae native to Asia. These fish live in fast-flowing streams in China, mainland Southeast Asia and the Indian subcontinent. They are mainly distributed in the Mekong, upper Salween and Irrawaddy River drainages. They range from the Brahmaputra basin to the Lam River drainage in central Vietnam. They are easily distinguished from other catfishes by their strongly depressed head and body and greatly enlarged paired fins that have been modified to form an adhesive apparatus. The flattened shape of these fish and the large pectoral and pelvic fins provide essential adhesion in the fast-flowing waters they live in.
Hemibagrus wyckii is a species of catfish of the family Bagridae. It is occasionally called the crystal-eyed catfish or black devil catfish.
Horabagrus is a genus of catfish in the family Horabagridae endemic to rivers in the Western Ghats in Kerala and Karnataka, India. H. brachysoma is an important food fish and members of this genus can be found in the aquarium trade.
Batasio is a genus of catfish of the family Bagridae. These small fish are found in fast-flowing hillstreams throughout South and mainland Southeast Asia.
Bagrichthys is a genus of bagrid catfishes.
Hemibagrus is a genus of catfishes of the family Bagridae.
Mystus is a genus of fish in the family Bagridae native to Asia. Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages.
Olyra is a genus of catfishes of the family Bagridae. This genus occurs throughout South Asia and western Indochina, from India to western Thailand.
Leiocassis is a genus of bagrid catfishes found mostly in Southeast Asia with some species occurring in China.
Pseudobagrus is a genus of bagrid catfishes that inhabit streams and rivers throughout East Asia. About half of these species occur in China.
Rita is a genus of fish in the family Bagridae found in South Asia. These species have a single pair of mandibular barbels, an elongated Weberian apparatus firmly sutured to the basioccipital and the sensory canal on the posttemporal enclosed with bone.
Pseudecheneis is a genus of sisorid catfishes native to Asia.
Acrochordonichthys is a genus of catfishes of the family Akysidae. It includes ten species.
Pseudobagarius is a genus of catfishes of the family Akysidae.
Microsynodontis is a genus of upside-down catfishes native to freshwater rivers in western Africa. The genus was originally described by British-Belgian zoologist George Albert Boulenger in 1903 based upon the type species Microsynodontis batesii. The name microsynodontis comes from the Greek word mikro, meaning small, and the Greek term synodon, meaning "with the teeth all growing together".
Hemibagrus semotus is a species of bagrid catfish found in the Padas River drainage and the shorter coastal rivers which drain the west face of the Crocker Range in northern Borneo, Sabah, Malaysia. This species reaches a length of 19.9 cm (7.8 in).
