“…Knowledge of each South American species varies from short latin narratives of Dr ESlNG (1850) to recent detailed, well-illustrated accounts [SCHOLZ et aI.

Keys to genera of cestodes in South American freshwater teleost fishes are provided, with diagnoses of genera and short descriptions of species. Two new genera are proposed, Chambriella gen.n. for Goezeella agostinhoi Pavanelli & Santos, 1992 and G paranaensis Pavanelli & Rego, 1989, and Brooksiella gen.n. for Amphoteromorphus praeputialis Rego, Santos & Silva, 1974. Nomimoscolex magna Rego, Santos & Silva, 1974, previously species inquirenda, is transferred to the genus Proteocephalus Weinland, 1858. Goezeella nupeliensis Pavanelli & Rego, 1989 is considered a species inquirenda. Species and host lists are included

“…De chambrier and Vaucher (1997) observed in this species that the uterine stem is in the ventral cortex and develops diverticula within the medulla as it is also the case in Endorchis piraeeba Woodland, 1934, another species parasitic in pimelodid catfishes in South America. This feature was also observed in Harriscolex kaparari (Woodland, 1935), Endorchis auchenipteri de chambrier et Vaucher, 1999, Gibsoniela meursaulti de chambrier et Vaucher, 1999, Nomimoscolex chubbi (Pavanelli et takemoto, 1995 and N. suspectus Zehnder, de chambrier, Vaucher et Mariaux, 2000, (Woodland 1934a, 1935b, Pavanelli and takemoto 1995, chambrier and Vaucher 1997, 1999, Zehnder et al 2000.…”

Between 2001 and 2003, the Department of invertebrates of the Natural History Museum in geneva, in collaboration with the south australian Museum, adelaide, the Queensland Museum, Brisbane and the University of Melbourne, Werribee, carried out a survey of the parasite fauna in australia, with a focus on cestodes of reptiles and amphibians. as a part of evaluation of the material recently found or deposited in museum collections, the systematic status of Ophiotaenia gallardi (Johnston, 1911) (syn. Proteocephalus gallardi Johnston, 1911 and Ophiotaenia hylae Johnston, 1912 was assessed. a study of the type material of O. gallardi has shown that it contains a mixture of two taxa, one of them representing a new species belonging to a new genus. Materials and MethodsFreshly collected worms were fixed immediately after host dissection with a hot 4% neutral formaldehyde solution, sorted in laboratory and then, after 3 weeks, transferred to 75% ethanol for storage. tapeworms for morphological observations were stained with Mayer's hydrochloric carmine, dehydrated in an ethanol series, cleared with eugenol (clove oil) and mounted in canada balsam. Pieces of the strobila were embedded in paraffin wax, cross-sectioned (thickness 12-15 µm), stained with Weigert's haematoxylin and counterstained with 1% acidic eosin B Hanzelová 1998, de chambrier 2001).scoleces for scanning electron microscopy (sEM) were processed as follows: worms were dehydrated in a graded ethanol series (80, 96, twice 100%), then transferred to a graded amyl acetate series, critical point dried in co 2 , sputter-coated with two new genera and two new species of proteocephalidean tapeworms (eucestoda) from reptiles and amphibians in australia sophie de Chambrier and alain de Chambrier Natural History Museum, Department of invertebrates, P.o. Box 6434, cH-1211 geneva 6, switzerland abstract: the examination of the type series of Ophiotaenia gallardi (Johnston, 1911) (syn. Proteocephalus gallardi Johnston, 1911) revealed that it is a mixture of two species of different genera. lectotype of Ophiotaenia gallardi is designated and the species is redescribed on the basis of it, conspecific paralectotypes and additional materials. The remaining part of the type series belongs to Vandiermenia gen. n. (acanthotaeniinae), with V. beveridgei sp. n. as the type-and only species. the new genus differs from all other acanthotaeniine genera, i.e. Rostellotaenia Freze, 1963, Acanthotaenia von linstow, 1903 and Kapsulotaenia Freze, 1963, by the presence of cortical uterine stem and paramuscular vitelline follicles, particular structure of the internal longitudinal musculature (absent laterally and more developed than in the three above-mentioned genera) and testes limited in two fields separated medially. Type series of Ophiotaenia mjobergi (Nybelin, 1917) (Johnston, 1912) comb. n. is proposed for Ophiotaenia hylae Johnston, 1912. Australotaenia gen. n. differs from the remaining genera of the subfamily acanthotaeniinae by (1) the type 2 of the formation of the uter...

“…it is interesting to note that the ovary of M. gracilis, a parasite of Neotropical fishes, is smaller (0.6-1.8%) than those of Proteocephalus species found in fishes from all over the world (5.4-28.8%) ( Table 2 in de chambrier et al 2012) and those of Ophiotaenia species occurring in reptiles from the New World (1.9-5.5%) ( Table 2 in On the apical surface of the scolex, capilliform filitriches are the most common microthrix type, this type being the only one found in, for example, Lenhataenia megacephala (Woodland, 1934); Monticellia lenha Woodland, 1933;M. magna (rego, dos santos et silva, 1974); Nomimoscolex chubbi (Pavanelli et takemoto, 1995); N. sudobim Woodland, 1935; Proteocephalus hemioliopteri de chambrier et Vaucher, 1997;P. sulcatus (Klaptocz, 1906); Spatulifer maringaensis Pavanelli et rego, 1989 andS.…”

Margaritaella gracilis gen. n. et sp. n. (Proteocephalidea: Proteocephalinae) found in the intestine of Callichthys callichthys (Linnaeus) from the Paraná River basin is described. The new genus is placed in the Proteocephalinae because of the medullary position of the genital organs. it differs from all known genera included in the Proteocephalinae by the following combination of characters: 1) scolex with a conspicuous cluster of drop-shaped gland cells posterior to suckers; 2) strobila with a low number of proglottides, all much longer than wide; 3) testes arranged in one field, composed of two parallel rows of testes separated by the uterus; 4) ovary delicate, H-shaped, with branches slender and deeply folliculate at the edges, located at 25-35% from the posterior end; 5) uterus largely extended posterior to the ovary but not reaching the end of proglottis; and 6) vitelline follicles in two narrow lateral bands, largely extended posterior to the ovary. scanning electron microscopy revealed three types of microtriches on the tegument surface: acicular and capiliform filitriches and gladiate spinitriches. The relative size of the ovary, a character recently used in the systematics of the proteocephalidean cestodes, was calculated for the new species and compared with other species of the group. M. gracilis is the first record of a proteocephalidean cestode parasitizing a callichthyid catfish.
