Monogenea is one of the most species-rich groups of parasitic flatworms worldwide, with many species described only recently, which is particularly true for African monogeneans. [] Key Method Worms collected from specimens of Limnochromis auritus, a cichlid belonging to the same cichlid tribe as G. permaxillaris, were used for comparison. Morphological as well as genetic characterisation was used for parasite identification. In total, all 73 Cichlidogyrus individuals collected from 'G.' pfefferi were…

Diversity and host specificity of monogenean gill parasites (Platyhelminthes) of cichlid fishes in the Bangweulu-Mweru ecoregion
TLDR
The parasite fauna in Bangweulu-Mweru is highly similar in species composition to Lake Kariba, but the same parasite species are more host-specific, probably because of hydrogeographical differences between the two regions.
Underexplored diversity of gill monogeneans in cichlids from Lake Tanganyika: eight new species of Cichlidogyrus Paperna, 1960 (Monogenea: Dactylogyridae) from the northern basin of the lake, with remarks on the vagina and the heel of the male copulatory organ
BackgroundLake Tanganyika harbours the most diverse cichlid assemblage of the Great African Lakes. Considering its cichlid flocks consist of approximately 250 endemic species, we can hypothesize a
Deep-water parasite diversity in Lake Tanganyika: description of two new monogenean species from benthopelagic cichlid fishes
TLDR
Investigating the monogenean fauna of Trematocara unimaculatum and Benthochromis horii found in the same deep-water habitat as the already known hosts of C. casuarinus found two new and non-resembling Cichlidogyrus species, which are new to science.
Reduced host-specificity in a parasite infecting non-littoral Lake Tanganyika cichlids evidenced by intraspecific morphological and genetic diversity
TLDR
The highly variable mitochondrial DNA indicated recent population expansion, but no ongoing parasite speciation, confirming, for the first time in freshwater, reduced parasite host specificity in the deepwater realm, probably an adaptation to low host availability.
Intraspecific morphological variation in Cichlidogyrus (Monogenea) parasitizing two cichlid hosts from Lake Tanganyika exhibiting different dispersal capacities
TLDR
Geomorphometric analyses revealed that populations of C. milangelnari, which parasitize poorly dispersing cichlids, are more differentiated than populations ofC.
Contrasting Host-Parasite Population Structure: Morphology and Mitogenomics of a Parasitic Flatworm on Pelagic Deepwater Cichlid Fishes from Lake Tanganyika
TLDR
The present study revealed the lake-wide occurrence of Cichlidogyrus casuarinus, a parasite with a broad host range infecting pelagic fishes endemic to Lake Tanganyika, and presented the first parasite mitogenome from LakeTanganyika and proposed a methodological framework for studying the intraspecific mitogenomic variation of dactylogyrid monogeneans.
First report of monogenean flatworms from Lake Tana, Ethiopia: gill parasites of the commercially important Clarias gariepinus (Teleostei: Clariidae) and Oreochromis niloticus tana (Teleostei: Cichlidae)
TLDR
This first study on the monogenean fauna of Lake Tana revealed that the lake’s North African catfish, as well as its endemic Nile tilapia subspecies, harbour parasites that are known from these host species elsewhere in Africa.
Some Parasitological Features of Paradiplozoon bliccae (Monogenea: Diplozoidae) Infestation in Pseudophoxinus burduricus - An Endemic Fish Species from Doğanbaba Creek (Lake Salda, Turkey)
TLDR
Prevalence, intensity, and seasonality of infection, age classes, and sex compositions of the infected population have been calculated and it has been recorded that the highest point of prevalence being in summer and the highest invasion value in the two-age class of fish.
Somewhere I belong: phylogeny and morphological evolution in a species-rich lineage of ectoparasitic flatworms infecting cichlid fishes
TLDR
It is shown that discrete characters can mask phylogenetic signals but can be key for characterising species groups, and a revaluation of characters included in species characterisations is needed.

Ancyrocephalidae (Monogenea) of Lake Tanganyika: does the Cichlidogyrus parasite fauna of Interochromis loocki (Teleostei, Cichlidae) reflect its host’s phylogenetic affinities?
TLDR
This study confirms that host range and host-specificity in Cichlidogyrus spp.
Ancyrocephalidae (Monogenea) of Lake Tanganyika: II: description of the first Cichlidogyrus spp. parasites from Tropheini fish hosts (Teleostei, Cichlidae)
TLDR
The genital and haptoral structure of the new species suggests a close relationship, which might mirror the close affinities between the hosts within the Tropheini, and belong to a morphological group within the genus containing parasites both of West African cichlids and of Haplochromini.
Evolutionary Relationships of the Limnochromini, a Tribe of Benthic Deepwater Cichlid Fish Endemic to Lake Tanganyika, East Africa
TLDR
The linearized tree analysis and the comparison of average sequence divergences to that of the remaining tribes of the H-lineage revealed a relatively recent but simultaneous proliferation of the Limnochromini, suggesting that the same environmental changes triggered the radiation of particular deepwater, benthic, pelagic, and littoral lineages.

TLDR
Cichlidogyrus species infecting African Great Lake cichlids are summarized and proposed as model for the influence of host ecology on disease transmission.
Hidden biodiversity in an ancient lake: phylogenetic congruence between Lake Tanganyika tropheine cichlids and their monogenean flatworm parasites
TLDR
In the first comprehensive phylogenetic parasitological analysis of a vertebrate radiation, monogenean parasites infecting tropheine cichlids from Lake Tanganyika are studied, revealing species-rich parasite assemblages and shows consistent host-specificity.
A phylogeny of Cichlidogyrus spp. (Monogenea, Dactylogyridea) clarifies a host-switch between fish families and reveals an adaptive component to attachment organ morphology of this parasite genus
TLDR
This study provides new evidence supporting the hypothesis of the adaptive nature of haptor morphology within Cichlidogyrus, and demonstrates this adaptive component for the first time within the attachment organs of which were usually considered to be mainly phylogenetically constrained.
Morphology, Molecules, and Monogenean Parasites: An Example of an Integrative Approach to Cichlid Biodiversity
TLDR
Traditional morphological methods meet their limitations in delineating species in Lake Tanganyika cichlids and monogenean Cichlidogyrus gill parasites, often highly species-specific, are used as complementary markers.
Two new species of Cichlidogyrus (Monogenea: Dactylogyridae) parasitizing the gills of African cichlid fishes (Perciformes) from Senegal: morphometric and molecular characterization
TLDR
Two new species of Cichlidogyrus are described from the gills of three species of African cichlids collected from the Gambia River basin in the Niokolo-Koba National Park, Senegal on the basis of morphological differences in the male copulatory organs (MCOs) and apparent similarities in the SSU rDNA and ITS1 sequence data.
SPECIATION BY HOST SWITCH AND ADAPTIVE RADIATION IN A FISH PARASITE GENUS GYRODACTYLUS (MONOGENEA, GYRODACTYLIDAE)
TLDR
The phylogenetic analysis demonstrated that G. (Limnonephrotus) is a monophyletic group that was originally hosted by cyprinids, and interestingly the adaptive radiation seems to be a consequence of host switch to a new family (key innovation model).
