Lamprologini
Lamprologini is a tribe of African cichlid fishes. It contains seven genera and nearly 100 species. Over half of the species in this tribe are in the large genus ''Neolamprologus''. Most genera in the tribe are endemic to Lake Tanganyika, but one species of ''Neolamprologus'' ('' N. devosi'') is from the Malagarasi River in Tanzania, and several species of ''Lamprologus'' are from the Congo River Basin. The species in this tribe are very small to medium-sized cichlids, but vary extensively in appearance and habitat preference.Smith, M.P. (1998). Lake Tanganyikan Cichlids, p. 10—11. Unlike most Tanganyika cichlids which are mouthbrooders, Lamprologini species are substrate spawners (typically using caves or rock crevices), and some are shell dwellers.

Neolamprologus
''Neolamprologus'' is a genus of cichlids endemic to eastern Africa with all but one species, ''Neolamprologus devosi'' from the Malagarasi River, occurring in Lake Tanganyika. It is the largest genus of cichlids in Lake Tanganyika and also the largest genus in the tribe Lamprologini, which includes ''Altolamprologus'', ''Chalinochromis'', ''Julidochromis'', ''Lamprologus'', ''Lepidiolamprologus'', ''Telmatochromis'' and '' Variabilichromis''. The latter is a monotypic genus doubtfully distinct from ''Neolamprologus''. It is already known for some time that according to mtDNA sequence analysis, this genus is very probably polyphyletic. It is likely that it will be revised eventually; if ''Variabilichromis'' is split off, at least some of the more ancient lineages currently placed in ''Neolamprologus'' are probably worthy of separation also. However, the morphological similarity and numerous undescribed species do not make analyses easier, and as with many cichlids, recent specia ...

Lepidiolamprologus
''Lepidiolamprologus'' is a small genus of cichlids endemic to Lake Tanganyika in eastern Africa. It is closely related to ''Altolamprologus.'' and there is the possibility that a revision of the genus could see more species added. The placement of '' L. cunningtoni'' has been questioned, as it seems to be a close relative of '' N. modestus'' and the Fourspine Cichlid (''N. tetracanthus''), though with hybridization running rampant in the Lamprologini, one cannot entirely be sure of its relationships at present. However it differs enough from the other species in ''Lepidiolamprologus'' to conclude that it may not belong in this genus.

Chalinochromis
''Chalinochromis'' is a small cichlid genus from the subfamily Pseudocrenilabrinae. These ray-finned fishes are endemic to Lake Tanganyika in the East African Rift. The scientific name refers to the bridle-like markings across the heads of members of this genus. They have specialized jaws enabling them to feed on sponges. (2007): Phylogenetic relationships of the Lake Tanganyika cichlid tribe Lamprologini: The story from mitochondrial DNA. '' Mol. Phylogenet. Evol.'' 45(2): 629–642. (HTML abstract) This genus has a puzzling relationship with the extremely similar species placed in ''Julidochromis''. In their mtDNA NADH dehydrogenase subunit 2 sequence, ''Chalinochromis'' are closer to '' J. dickfeldi'', '' J. ornatus'' and '' J. transcriptus'' – in particular the latter two – than to any other living fish, while '' J. marlieri'' and '' J. regani'' are closer to ''Telmatochromis''. ''Julidochromis'' thus might need to be split in two, with ''Chalinochromis'' include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telmatochromis
__NOTOC__ ''Telmatochromis'' is a small cichlid genus of the subfamily Pseudocrenilabrinae. These ray-finned fishes are endemic to the Lake Tanganyika basin (mostly in the lake itself, but also its outflow river Lukuga) in Africa. Systematics Analysis of their mtDNA NADH dehydrogenase subunit 2 (ND2) sequence shows that hybridization must have played some role in the evolution of this genus. (2007): Phylogenetic relationships of the Lake Tanganyika cichlid tribe Lamprologini: The story from mitochondrial DNA. '' Mol. Phylogenet. Evol.'' 45(2): 629–642. (HTML abstract) For one thing, it might be that ''Telmatochromis'' is close to ''Julidochromis'', which they somewhat resemble. A possibility is hybridization between the ancestor of ''Telmatochromis'' and a lineage of ''Julidochromis'' which later gave rise to '' J. marlieri'' and the Convict Julie (''J. regani''). Similar ND2 DNA has been found in these and '' T. bifrenatus'', '' T. brichardi'' and '' T. temporalis''. '' T. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julidochromis
''Julidochromis'' is a genus of cichlids in the subfamily Pseudocrenilabrinae. They are commonly called julies and are endemic to Lake Tanganyika in eastern Africa. This genus includes six formally described species, some with a number local variants of uncertain taxonomic status. Further taxonomic work is required to determine how many species exist; the closely related ''Chalinochromis'' with two more species is sometimes included here and this may be correct. Hybridization makes attempts to determine relationships with molecular phylogenetic methods difficult. These ray-finned fish are smallish to mid-sized (about ) and have a yellowish background colour with black lengthwise stripes or a checkerboard pattern. Species There are currently 6 formally described species in this genus: * ''Julidochromis dickfeldi'' Staeck, 1975 * ''Julidochromis marksmithi'' W. E. Burgess, 2014 Burgess, W.E.

Altolamprologus
''Altolamprologus'' is a small genus of pseudocrenilabrine cichlids endemic to Lake Tanganyika in eastern Africa. They inhabit areas of the lake with large amounts of rock, most frequently in water two to ten metres in depth. Two formally described species comprise this genus, with perhaps one dwarf ''A. compressiceps''-like species being considered an undescribed species by some. Species There are currently two recognized species in this genus: * ''Altolamprologus calvus'' (Poll, 1978) * ''Altolamprologus compressiceps'' ( Boulenger, 1898) Description They are moderately-sized Lamrologines, growing to a total length of in adult males. Their bodies are laterally compressed and remarkably high-backed; hence the scientific name which means "high ''Lamprologus''" (from Latin ''altus'', "high"). They are predators which feed on large invertebrates and small fish, particularly crustaceans and juveniles of other cichlids. In the aquarium ''Altolamprologus'' are hardy at the stand ...

Pseudocrenilabrinae
The Pseudocrenilabrinae are a subfamily in the cichlid family of fishes to which, according to a study from 2004, includes all the Middle Eastern and African cichlids with the exception of the unusual '' Heterochromis multidens'' and the Malagasy species. This subfamily includes more than 1,100 species. Previous authors recognized additional African subfamilies, e.g. the Tilapiinae of Hoedeman (1947), Tylochrominae of Poll (1986), or Boulengerochrominae of Tawil (2001). To this subfamily belong the cichlids from the African Great Lakes, such as the utaka and mbuna in Lake Malawi, and various species from Lake Victoria and Lake Tanganyika. The Pseudocrenilabrinae tribes Haplochromini and Oreochromini are widespread in Africa and also found in the Middle East, while Chromidotilapiini, Hemichromini and Tylochromini are primarily West and Central African. The remaining tribes are largely or entirely restricted to Lake Tanganyika. Systematics Apart from the tribes mentioned in th ...

Lake Tanganyika
Lake Tanganyika () is an African Great Lake. It is the second-oldest freshwater lake in the world, the second-largest by volume, and the second-deepest, in all cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo (DRC), Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean. Etymology "Tanganika" was the name of the lake that Henry Morton Stanley encountered when he was at Ujiji in 1876. The name first originated from the Bembe language when they arrived in South Kivu around the 7th century, they discovered the lake and started calling it “êtanga ‘ya’ni’â” which means “a big river” in their Bantu language. Stanley found also other names for the lake among different ethnic groups, like the Kimana, the Yemba and the Msaga. An alt ...

Shell Dwellers
The terms shell dwellers or shelldwellers, shell-breeding, or ostracophil are descriptive terms for cichlid fish that use the empty shells of aquatic snails as sites for breeding and shelter. The terms have no taxonomic basis, although most shell-dwelling cichlids are from Lake Tanganyikas lamprologine lineage.Loiselle PV. (1994) The Cichlid Aquarium, Voyageur Press, Many shell dwelling cichlids are popular with fishkeepings and are frequently kept in aquaria. Shell origins In Lake Tanganyika the shells inhabited are from the genus '' Neothauma'', while shells used by '' Pseudotropheus lanisticola'' in Lake Malawi are from genus ''Lanistes''. Shell Dwelling Cichlids Around 24 species of lamprologine cichlids use abandoned shells for shelter and breeding in Lake Tanganyika. Most, however, are not obligate shell-breeding cichlids and will spawn in other caves or crevices. Types of shell dwellers There are several groups the shell dwellers can be placed into: *Colonial shel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamprologus
''Lamprologus'' is a genus of fishes from the cichlid Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this ... family. They are native to Lake Tanganyika (where several species are shell dwellers) and the Congo River Basin in Africa. The type species for this genus is ''Lamprologus congoensis'', a species from the Congo River. The genus is under some revision and may eventually be restricted to these riverine types. Species There are currently 20 recognized species in this genus: * ''Lamprologus callipterus'' George Albert Boulenger, Boulenger, 1906 * ''Lamprologus congoensis'' Louise Schilthuis, Schilthuis, 1891 * ''Lamprologus finalimus'' John Treadwell Nichols, Nichols & Francesca Raimonde La Monte, La Monte, 1931 * ''Lamprologus kungweensis'' Max Poll, Poll, 1956 * ''Lamprologus la ...
