Hybridization among littoral cichlid species in Lake Tanganyika was inferred in several molecular phylogenetic studies. The phenomenon is generally attributed to the lake level-induced shoreline and habitat changes. These allow for allopatric divergence of geographically fragmented populations alternating with locally restricted secondary contact and introgression between incompletely isolated taxa. In contrast, the deepwater habitat is characterized by weak geographic structure and a high potential for gene flow, which may explain the lower species richness of deepwater than littoral lineages. For the same reason, divergent deepwater lineages should have evolved strong intrinsic reproductive isolation already in the incipient stages of diversification, and, consequently, hybridization among established lineages should have been less frequent than in littoral lineages. We test this hypothesis in the endemic Lake Tanganyika deepwater cichlid tribe Bathybatini by comparing phylogenetic trees of Hemibates and Bathybates species obtained with nuclear multilocus AFLP data with a phylogeny based on mitochondrial sequences. -

Mitochondrial ND2 Phylogeny of Tilapiines and the Evolution of Parental Care Systems in the African Cichlid Fishes
What, if Anything, is a Tilapia?ÐMitochondrial ND2 Phylogeny of Tilapiines and the Evolution of Parental Care Systems in the African Cichlid Fishes Vera Klett and Axel Meyer Department of Biology, University of Konstanz, Germany We estimated a novel phylogeny of tilapiine cichlid ®sh (an assemblage endemic to Africa and the Near East) within the African cichlid ®shes on the basis of complete mitochondrial NADH dehydrogenase subunit 2 (ND2) gene sequences. The ND2 (1,047 bp) gene was sequenced in 39 tilapiine cichlids (38 species and 1 subspecies) and in an additional 14 nontilapiine cichlid species in order to evaluate the traditional morphologically based hypothesis of the respective monophyly of the tilapiine and haplochromine cichlid ®sh assemblages. The analyses included many additional cichlid lineages, not only the so-called tilapiines, but also lineages from Lake Tanganyika, east Africa, the Neotropics and an out-group from Madagascar with a wide range of parental care and mating systems. Our results suggest, in contrast to the historical morphology-based hypotheses from Regan (1920, 1922), Trewavas (1983), and Stiassny (1991), that the tilapiines do not form a monophyletic group because there is strong evidence that the genus Tilapia is not monophyletic but divided into at least ®ve distinct groups. In contrast to this ®nding, an allozyme analysis of Pouyaud and AgneÁse (1995), largely based on the same samples as used here, found a clustering of the Tilapia species into only two groups. This discrepancy is likely caused by the difference in resolution power of the two marker systems used. Our data suggest that only type species Tilapia sparrmanii Smith (1840) should retain the genus name Tilapia. -
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. -

We investigatedbody shape variation, quanti ed usinglandmark-based geometric morphometrics, among cichlidspecies belonging to algaland zooplankton feeders coexisting along the rocky shores of Lake Malawi,in order to elucidate the adaptive signi cance of body shape. Signi cant differences were foundwithin zooplankton feeders in which Copadichromisborleyi hada shortergape, smaller eyes andshorter caudal peduncle relative to Ctenopharynxpictus and,within algal feeders, Labeotropheus fuelleborni hada shorterand inferior subterminal gape, and shorter head relative to Petrotilapiagena- lutea.Variationamong species is discussedwith reference to trophicand feeding microhabitat differ- entiationwhich enables us to appreciate the role -
