Es gab noch kein Internet, der Mergus-Aquarienatlas bot damals nur unzureichende Informationen über die Lebensräume und Haltungsbedin- gungen der Cichliden aus dem See, und nur gelegentlich fand man ein paar Infos in einer Aquarienzeitschrift.

Checklist of the Cichlid Fishes of Lake Malawi (Lake Nyasa)
Checklist of the Cichlid Fishes of Lake Malawi (Lake Nyasa/Niassa) by M.K. Oliver, Ph.D. ––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––– Checklist of the Cichlid Fishes of Lake Malawi (Lake Nyasa/Niassa) by Michael K. Oliver, Ph.D. Peabody Museum of Natural History, Yale University Updated 3 November 2018 First posted June 1999 The cichlids of Lake Malawi constitute the largest vertebrate species flock and largest lacustrine fish fauna on earth. This list includes all cichlid species, and the few subspecies, that have been formally described and named. Many–several hundred–additional endemic cichlid species are known but still undescribed, and this fact must be considered in assessing the biodiversity of the lake. Recent estimates of the total size of the lake’s cichlid fauna, counting both described and known but undescribed species, range from 700–843 species (Turner et al., 2001; Snoeks, 2001; Konings, 2007) or even 1000 species (Konings 2016). Additional undescribed species are still frequently being discovered, particularly in previously unexplored isolated locations and in deep water. The entire Lake Malawi cichlid metaflock is composed of two, possibly separate, endemic assemblages, the “Hap” group and the Mbuna group. Neither has been convincingly shown to be monophyletic. Membership in one or the other, or nonendemic status, is indicated in the checklist below for each genus, as is the type species of each endemic genus. The classification and synonymies are primarily based on the Catalog of Fishes with a few deviations. All synonymized genera and species should now be listed under their senior synonym. Nearly all species are endemic to L. Malawi, in some cases extending also into the upper Shiré River including Lake Malombe and even into the middle Shiré. -

CICHLIFORMES: Cichlidae (part 5) · 1 The ETYFish Project © Christopher Scharpf and Kenneth J.

Global Catfish Biodiversity 17

ARMBRUSTER* Department of Biological Sciences, Auburn University 331 Funchess, Auburn University, Alabama 36849, USA Abstract.—Catfi shes are a broadly distributed order of freshwater fi shes with 3,407 cur- rently valid species. In this paper, I review the different clades of catfi shes, all catfi sh fami- lies, and provide information on some of the more interesting aspects of catfi sh biology that express the great diversity that is present in the order. I also discuss the results of the widely successful All Catfi sh Species Inventory Project. Introduction proximately 10.8% of all fi shes and 5.5% of all ver- tebrates are catfi shes.

Catfi shes (the Siluriformes) occur has long jaws but could not be called large.

C. Darrin Hulsey1* , Jimmy Zheng2, Roi Holzman3, Michael E. Alfaro2, Melisa Olave1 and Axel Meyer1 Abstract Background: Phylogenies provide critical information about convergence during adaptive radiation. To test whether there have been multiple origins of a distinctive trophic phenotype in one of the most rapidly radiating groups known, we used ultra-conserved elements (UCEs) to examine the evolutionary affinities of Lake Malawi cichlids lineages exhibiting greatly hypertrophied lips. Results: The hypertrophied lip cichlids Cheilochromis euchilus, Eclectochromis ornatus, Placidochromis “Mbenji fatlip”, and Placidochromis milomo areallnestedwithinthenon-mbunacladeofMalawi cichlids based on both concatenated sequence and single nucleotide polymorphism (SNP) inferred phylogenies. Lichnochromis acuticeps that exhibits slightly hypertrophied lips also appears to have evolutionary affinities to this group. However, Chilotilapia rhoadesii that lacks hypertrophied lips was recovered as nested within the species Cheilochromis euchilus. Species tree reconstructions and analyses of introgression provided largely ambiguous patterns of Malawi cichlid evolution. -
Cytogenetics of Gymnogeophagus Setequedas (Cichlidae: Geophaginae), with Comments on Its Geographical Distribution
Neotropical Ichthyology, 15(2): e160035, 2017 Journal homepage: www.scielo.br/ni DOI: 10.1590/1982-0224-20160035 Published online: 26 June 2017 (ISSN 1982-0224) Copyright © 2017 Sociedade Brasileira de Ictiologia Printed: 30 June 2017 (ISSN 1679-6225) Cytogenetics of Gymnogeophagus setequedas (Cichlidae: Geophaginae), with comments on its geographical distribution Leonardo M. Paiz1, Lucas Baumgärtner2, Weferson J. da Graça1,3, Vladimir P. Margarido1,2 and Carla S. Pavanelli1,3 We provide cytogenetic data for the threatened species Gymnogeophagus setequedas, and the first record of that species collected in the Iguaçu River, within the Iguaçu National Park’s area of environmental preservation, which is an unexpected occurrence for that species. We verified a diploid number of 2n = 48 chromosomes (4sm + 24st + 20a) and the presence of heterochromatin in centromeric and pericentromeric regions, which are conserved characters in the Geophagini. The multiple nucleolar organizer regions observed in G. setequedas are considered to be apomorphic characters in the Geophagini, whereas the simple 5S rDNA cistrons located interstitially on the long arm of subtelocentric chromosomes represent a plesiomorphic character. Because G. setequedas is a threatened species that occurs in lotic waters, we recommend the maintenance of undammed environments within its known area of distribution. Keywords: Chromosomes, Conservation, Iguaçu River, Karyotype, Paraná River. Fornecemos dados citogenéticos para a espécie ameaçada Gymnogeophagus setequedas, e o primeiro registro da espécie coletado no rio Iguaçu, na área de preservação ambiental do Parque Nacional do Iguaçu, a qual é uma área de ocorrência inesperada para esta espécie. Verificamos em G. setequedas 2n = 48 cromossomos (4sm + 24st + 20a) e heterocromatina presente nas regiões centroméricas e pericentroméricas, as quais indicam caracteres conservados em Geophagini. -

Review of the Apistogramma species, with description of a new species (Teleostei, Cichlidae).-Zool. Scr. 11: 307-313. Apistogramma inconspicua sp.n. is described from the Rio Candclaria in the Rio GuaporC drainage in Bolivia, and recorded also from Caceres on the Rio Paraguay in Brazil. The new species is closely related to the Paraguayan species A. commbrae (Regan) and an undescribed species in the GuaporC drainage system. These species share a specialized feature in the colour pattern, viz. an expanded vertical bar on the caudal peduncle which it confluent with the caudal spot. The now presumably complete record of Paraguayan Apistogramma species allows an analytical key to be given. Of the additional species, A. borellii (Regan) and A. rrifasciata (Eigenmann & Kennedy) represent two distinct lineages. Apistogramma pleurotaenia (Regan) is probably a La Plata basin species, although no localities are known, and its relationship remain obscure. The assemblage of Paraguayan Apistogramma species reflects the heterogeneity of the Paraguayan cichlid fauna as a whole. Sven 0.

Freshwater Fishes of Argentina: Etymologies of Species Names Dedicated to Persons
Ichthyological Contributions of PecesCriollos 18: 1-18 (2011) 1 Freshwater fishes of Argentina: Etymologies of species names dedicated to persons. Stefan Koerber Friesenstr. 11, 45476 Muelheim, Germany, [email protected] Since the beginning of the binominal nomenclature authors dedicate names of new species described by them to persons they want to honour, mostly to the collectors or donators of the specimens the new species is based on, to colleagues, or, in fewer cases, to family members. This paper aims to provide a list of these names used for freshwater fishes from Argentina. All listed species have been reported from localities in Argentina, some regardless the fact that by our actual knowledge their distribution in this country might be doubtful. Years of birth and death could be taken mainly from obituaries, whereas those of living persons or publicly unknown ones are hard to find and missing in some accounts. Although the real existence of some persons from ancient Greek mythology might not be proven they have been included here, while the names of indigenous tribes and spirits are not. If a species name does not refer to a first family name, cross references are provided. Current systematical stati were taken from the online version of Catalog of Fishes.
