However, both proved synonyms of C. proximus Gusev, During further studies on the genus Cornudiscoides, two new species, infesting S. aor, have been collected and studied in detail. The worldwide distribution of monogenean genera described from cichlid hosts shows a clear difference between the distributions of ecto- (i.e., living on the host, directly in contact with the environment) and mesoparasite (i.e., living in a host body cavity and not in direct contact with the external environment []) mesoparasite Enterogyrus is present in Asia, the whole of Cited by: L.

Of a total of 38 nominal genera, only 19 are considered valid. Seventeen of these 19 genera are currently in the Ancyrocephalidae (containing the Ancyrocephalinae and Ancylodiscoidinae), whilst the other two (Neocalceostoma and Cited by: In Central, West, and South Africa, most of the published works are dealing with taxonomic and epidemiological studies of monogeneans in Cichlids [53.

The class Monogenoidea is a fairly large group of parasitic flatworms belonging to the phylum Platyhelminthes. Monogeneans are generally found on bony fishes in freshwater and marine habitats.

Although some are endoparasites in the urinary bladder and eyes, most monogeneans are ectoparasites that attach to their host’s skin or gills by a special posteriorly positioned.

The following dactylogyridean monogeneans Author: José Francalino Vital. The African freshwater fish of Cichlidae are parasitized by five genera of monogeneans belonging to Dactylogyridea.

Ectoparasitic Scutogyrus, Onchobdella, and the highly diversified Cichlidogyrus represent three genera located on the gills, while the endoparasitic Enterogyrus and Urogyrus are located in the stomach and the urinary bladder, by: these haptoral structures in dactylogyridean monogeneans have been extensively studied in various ecological and evo-lutionary contexts because of their influence on the host specificity, parasite specialization and reproductive isolation among congeners through niche ecology [12, 20 –22].

Haptoral structures and MCO in Cichlidogyrus spp. Phylogenetic framework for the closely related Ancylodiscoidinae and Ancyrocephalinae subfamilies remains contentious. As this issue was never studied using a large molecular marker, we sequenced the first two Ancylodiscoidinae mitogenomes: Thaparocleidus asoti and Thaparocleidus varicus.

Both mitogenomes had two non-coding regions (NCRs) that Author: Dong Zhang, Hong Zou, Ivan Jakovlić, Shan G. Wu, Ming Li, Jin Zhang, Rong Chen, Wen X. Li, Gui T. The organism of interest: Monogenea Carus, Prior to exploring methods to be used in constructing a generic 3D model which can be deformed into different shapes, we would like to briefly describe the subject of this study, the monogeneans, and the rationale for developing deformable 3D models for the various hard parts of the by: 3.

The monogeneans of other African freshwater fish families have recently also become the subject of molecular phylogenetic research, including those infecting catfishes (Francová etal.

) and cyprinids (Šimková etal. The above-mentioned work on the evolution of African monogeneans deals mainly with representatives of the Dactylogyridea.

Morphologies and morphometries as diagnostic characters are shown statistically to be able to differentiate between species and intraspecific variants.

Intraspecific variants or morphovariants exist in nature but the variations they possessed are not enough to consider them as species (differentiation index values for morphovariants is 50% less than the values for species).

Three species of Volsellituba n. and two species of Pennulituba n. are described from the gills of the yellowfin goatfish Mulloidichthys vanicolensis (Valenciennes) off New Caledonia (South Pacific). Volsellituba and Pennulituba resemble dactylogyrid genera whose species lack eye-spots and possess tandem or slightly overlapping gonads, a single prostatic Cited by:   Its importance has been reported in other dactylogyridean monogeneans, e.g.

Representatives of four dactylogyridean. In the Monogenea the principal contributions to phylogeny and evolutionary considerations of spermatological characters were made by Justine (b) and Justine et al.

In these studies, the monopisthocotylean and polyopisthocotylean monogeneans were each defined on the basis of synapomorphies for the spermatozoon. All 73 adult monogeneans collected from ‘G:’ pfefferi specimens were identified as C.

Monogeneans normally have cephalopods (octopus and squid), fish, amphibians, reptiles and cetaceans (whales) as their primary hosts and some smaller animal that the primary host eats as their intermediate host.

An interesting Monogenean is the small Gyrodactylus elegans. This 1 mm long animal lives in the gills of European Carp, it is. With regard to parasitological studies, and even more so when specifically referring to monogeneans, Africa is still insufficiently explored and new genera are regularly reported from African freshwater fishes, e.g.

Literature reviews of reports concerning the parasitic fauna of fishes of Al-Diwaniyah province, Iraq till the end of December showed that a total of 43 parasite species are so far known from 13 valid fish species investigated for parasitic infections.

Considering its cichlid flocks consist of approximately endemic species, we can hypothesize a high species-richness in their often quite host-specific monogenean ectoparasites belonging to Cichlidogyrus Paperna, Yet, only 24 species were described Cited by: 2.
