“…The polar capsules of C. australis are also more teardrop-shaped compared to the almost spherical polar capsules of C. cottoidii. Ceratomyxa cottoidii resembles C. lagocephali Kpatcha, Diebakate, Faye et Toguebaye, 1996 described from the gall bladder of Lagocephalus laevigatus off the coast of Senegal by Kpatcha et al (1996b). The spores of C. lagocephali are more broadly crescent-shaped than C. cottoidii.…”

“…In Africa only nine Ceratomyxa species have been described from marine fish hosts (Dubina and Isakov 1976, Gaevskaya and Kovaleva 1979, Kpatcha, et al 1996b) (see Table 1). The majority of these were described from fishes collected off the coast of Senegal by Kpatcha et al (1996b).…”

“…Ceratomyxa fistulariae Kpatcha, Diebakate, Faye et Toguebaye, 1996, described from the bile ducts of Fistularia petimba in Senegal by Kpatcha et al (1996b), is similar in general spore shape, but has a much greater spore width than C. dehoopi (Table 2). Comparatively, C. truncata Thélohan, 1895 found infecting the bile ducts of Sardinella madarensis also in Senegal by Kpatcha et al (1996b), has a much broader spore (Table 2), is more strongly arched and has a prominent sutural ridge, unlike the smaller less arched spores of C. dehoopi. Compared with species from around the world, C. dehoopi resembles C. arripica Su et White, 1994 described from the gall bladder of Arripis trutta in Tasmania, Australia by Su and White (1994).…”

“…Morphologically the most similar African species is C. lagocephali, but this species has a relatively longer spore body length than C. honckenii (Kpatcha et al 1996b) (Table 2), giving the spores of C. honckenii a narrower appearance than the broader spores of C. lagocephali. Another similar African species is C. acanthuri Kpatcha, Diebakate, Faye et Toguebaye, 1996 described from the gall bladder of Acanthurus monroviae in Senegal (Kpatcha et al 1996b). Ceratomyxa acanthuri does, however, have a much longer spore length and narrower spore width (Table 2) than the slightly more transversely elongate spores of C. honckenii.…”

Abstract. Current records of marine myxozoans from the coast of Africa are limited to the descriptions of 52 species from mostly Senegal, with a few from Tunisia and southern Africa. Between 1998 and 2000 several intertidal fishes from the southern Cape coast of South Africa were examined for the presence of myxozoan infections. Three new species, Ceratomyxa dehoopi sp. n., C. cottoidii sp. n. and C. honckenii sp. n. were identified from the gall bladders of Clinus superciliosus L., C. cottoides Valenciennes and Amblyrhynchotes honckenii (Bloch), respectively. A fourth new species Henneguya clini sp. n. was also identified from the gills and gill arches of C. superciliosus.Very little is known about the distribution and diversity of marine myxozoans along Africa's coastline. Research on these parasites is restricted to the description of 52 species from the entire extent of the African coastline, the majority of which were described from Senegal. Early records of myxozoan infections in African marine fishes appeared from southern Africa between 1919 . Fantham (1919, 1930 recorded several myxozoan species from the bile of a number of intertidal fishes along the Cape south coast. Gilchrist (1924) described Chloromyxum thyrsites Gilchrist, 1924 from the muscles of Cape Sea fish, or "snoek", which is a species well-known around the world today as the notorious Kudoa thyrsites (Gilchrist, 1924). Subsequent to Gilchrist's (1924) description, Davies and Beyers (1947) recorded the presence of K. thyrsites in some of the South African trawled fishes and during the 1970s Dubina and Isakov (1976), Gaevskaya and Kovaleva (1979) as well as Schulman et al. (1979) described several new myxozoan species from deep sea fish off the coast of southern Africa.After these initial myxozoan publications from southern Africa, approximately 15 years passed before a number of species descriptions started to appear from the North-West coast of Africa (Bahri et al. 1995, Bahri and Marqués 1996, Kpatcha et al. 1996a, b, 1997). Subsequent to these publications Ali (2000) described Ortholinea basma Ali, 2000 from the gall bladder of the agile klipfish Clinus agilis, from the West coast of South Africa. This paper represents the first publication on the occurrence of myxozoans infecting intertidal fishes from the De Hoop Nature Reserve along the south coast of South Africa. Three new species of the genus Ceratomyxa Thélohan, 1892, are described from the gall bladders of Clinus superciliosus L., C. cottoides Valenciennes and Amblyrhynchotes honckenii (Bloch), respectively. A fourth new species from the genus Henneguya Thélohan, 1892 is described from the gills and gill arches of C. superciliosus. MATERIALS AND METHODSA total of 14 Amblyrhynchotes honckenii, 44 Clinus cottoides and 131 C. superciliosus were collected on several fieldtrips to the De Hoop Nature Reserve and Jeffrey's Bay, both of which are situated along the south coast of South Africa. Fishes were collected from intertidal rock pools using small hand nets and hand lines. Captu...

Morphology and small subunit rDNA-based phylogeny of Ceratomyxa amazonensis n. sp. parasite of Symphysodon discus, an ornamental freshwater fish from Amazon

The specious genus Ceratomyxa Thélodan, 1892, infect mainly gallbladder of marine fishes, with only five species reported infecting species from freshwater environment. This study performed morphological and phylogenetic analyses involving a new Ceratomyxa species (Ceratomyxa amazonensis n. sp.) found in gallbladder of Symphysodon discus Heckel, 1840 (Perciformes: Cichlidae), an important ornamental fish endemic to Amazon basin. Mature spores were strongly arcuate shaped and measured 7.0 ± 0.3 (6.2-7.6) μm in length, 15.8 ± 0.4 (15.0-16.7) μm in thickness, and polar capsules 3.22 ± 0.34 (2.4-3.6) μm in length and 2.63 ± 0.17 (2.4-2.9) μm in width. This was the first small subunit ribosomal DNA (SS rDNA) sequencing performed to Ceratomyxa species parasite of freshwater fish, and the phylogenetic analysis showed C. amazonensis n. sp. clustering in the early diverging subclade of the ceratomyxids, together with species of parasites of amphidromous/estuaries fishes, suggesting some role of the transition of the fishes between marine/freshwater environments in the evolutionary history of these parasites.
