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...

“…Considering the medullary position of testes, ovary, uterus and vitelline follicles, coupled with a scolex with uniloculate suckers and testes in one field, this taxon could be placed in Proteocephalus Weinland, 1858. However, almost all proteocephalidean cestodes found in reptiles and amphibians are members of Ophiotaenia La Rue, 1911 (see Freze, 1965;de Chambrier et al, 2006;Ammann & de Chambrier, 2008;Coquille & de Chambrier, 2008), which differs from Proteocephalus essentially in the presence of two testicular fields and a preformed uterus (Freze, 1965). Both Proteocephalus and Ophiotaenia have been demonstrated to be polyphyletic in previous phylogenetic analyses (Zehnder & Mariaux, 1999;de Chambrier et al, 2004a;Hypša et al, 2005).…”

Testudotaenia testudo (Magath, 1924) is redescribed from the intestine of the softshell turtle Apalone spinifera (Le Sueur) (Trionychidae) and the bowfin Amia calva Linnaeus (Amiidae) from Reelfoot Lake, Tennessee, United States. A new subfamily, the Testudotaeniinae, is erected. The new taxon differs from all proteocephalidean subfamilies in the position of the genital organs in relation to the longitudinal internal musculature, i.e. the testes are cortical, rarely medullary; the ovary is partly medullary, with cortical lobes; the vitelline follicles are mainly medullary, with some follicles in the cortex; and the uterus is cortical. A key to the subfamilies of the order Proteocephalidea Mola, 1928 is provided. The most characteristic features of T. testudo are the precocious uterine aperture, the presence of internal uterine pores (as previously described for Proteocephalus paraguayensis (Rudin, 1917)), the eggs laid unripe, the very long strobila (up to 970 mm), and the presence of an anterior circular musculature in the suckers, which is considered as a good differential character. Three other species were found in Amia calva: Proteocephalus perplexus La Rue, 1911, P. ambloplitis (Leidy, 1887) and a new, undescribed form. Sequences of the partial nuclear 28S rRNA gene of specimens of T. testudo from Apalone spinulifera and Amia calva confirm the conspecificity of samples from these two very distinct hosts, which may represent a capture phenomenon. As the subfamily Adenobrechmoinae Bursey, Goldberg & Kraus, 2006 and the genus Adenobrechmos Bursey, Goldberg & Kraus, 2006 are based on the presence of an apical organ, a character which reflects a rather common convergence, we consider the Adenobrechmoinae to be a junior synonym of the Proteocephalinae La Rue, 1911 and Adenobrechmos a junior synonym of Ophiotaenia La Rue, 1911. Adenobrechmos greeri Bursey, Goldberg & Kraus, 2006 thus becomes Ophiotaenia greeri (Bursey, Goldberg & Kraus, 2006) n. comb.

“…Interestingly, all but one species of Clade K listed above have an embryophore of a similar size (diameter always less than 34 μm), the only exception being the new species, O. echidis , with extraordinarily large embryophore (diameter 44–53 μm). The presence of a third layer in the embryophore is not common in the Proteocephalidae and has been observed only in some proteocephalids parasitising reptiles from different genera, such as Australophiotaenia , Cairaella Coquille et de Chambrier, 2008, Kapsulotaenia Freze, 1963, Macrobothriotaenia and Ophiotaenia from the Old World (Asia, Australia and Madagascar), and in Cairaella henrii Coquille et de Chambrier, 2008, a parasite of the polychrotid lizard Norops trachyderma (= Anolis trachyderma Cope) in Ecuador ( Coquille and de Chambrier, 2008 ; Scholz et al, 2013 ; de Chambrier et al, 2018 , 2020 ). The only proteocephalid parasitising amphibians that possesses a third embryophore layer is Ophiotaenia alessandrae Marsella et de Chambrier, 2008 from Hyla boans (= Boana boans (Linnaeus)) in Ecuador ( Marsella and de Chambrier, 2008 ).…”

Ophiotaenia echidis n. sp. (Cestoda: Proteocephalidae) is described from the intestine of one of the world's deadliest snakes, the saw-scaled viper Echis carinatus sochureki Stemmler (Ophidia: Viperidae) in the United Arab Emirates. The new species differs from other species of the non-monophyletic Ophiotaenia by the position of testes in two longitudinal lines on both sides of the uterus, and by the large size of an embryophore (diameter of 44–55 μm versus less than 40 μm in other species). Phylogenetic reconstructions based on lsr DNA and concatenated lsr DNA + COI datasets place the new species among proteocephalids from unrelated zoogeographical realms but mostly infecting venomous snakes. In all analyses, O . echidis n. sp. exhibited a strongly supported sister relationship with O. lapata Rambeloson, Ranaivoson et de Chambrier, 2012, a parasite of a pseudoxyrhophiid snake endemic to Madagascar. Despite a shared close evolutionary history between these taxa, morphological synapomorphies remain unclear, which impedes the erection of a new genus to accommodate them. A list of the 71 tapeworms of the former, non-monophyletic subfamily Proteocephalinae, parasitising snakes and lizards, including species inquirendae , and the phylogenetically closely related Thaumasioscolex didelphidis from opossum, with selected characteristics, is also provided, together with a checklist of helminth parasites reported from E. carinatus .
