“…The fundamental frequency and pulse rate of calling males differs from all other known X. laevis subspecies. Lastly, Jackson and Tinsley (1997) found that egg size of Dollfuschella rodhaini, a digenean parasite of Xenopus spp. was signi cantly different between X. l. laevis (collected from the Cape and Transkei of South Africa and Mazoe in Zimbabwe) and all other Xenopus species or subspecies examined.…”

Xenopus laevis (Daudin, 1802) has been the subject of numerous studies but is taxonomically poorly understood. Part of the Cytochrome b gene in mitochondrial DNA was sequenced from 50 individual Xenopus from three currently recognised species, taken from 28 localities in southern Africa, and from an outgroup of two West African X. epitropicalis. Phylogenetic analyses of these data reveal well-supported tree structure, demonstrating three clades within what is currently regarded as X. laevis: X. l. laevis from the Cape, X. l. petersii, and X. l. laevis from further north. This evidence agrees with other studies (on morphology, call and parasite data) which suggest that what is currently regarded as X. laevis encompasses more than one species. Workers using Xenopus collected away from the Cape of South Africa are not safe in assuming that they are using X. laevis.

“…doyeri has been reported to occur widely in sub-Saharan Africa including territories with varying temperatures such as lowland tropical rain forest, montane forest, upland savanna or wooded grassland, arid savanna and mediterranean climatic conditions (the Cape) . Similarly, the distribution of D. rodhaini extends from the Cape into central Africa (Jackson & Tinsley, 1997). Table 3.…”

Diversity of parasites from Xenopus laevis (Amphibia: Pipidae) and their seasonal rate of infection in selected habitats in the Limpopo Province, South Africa

2020

SummaryThis study determined the diversity and seasonality of parasites species of the African clawed frog, Xenopus laevis (Daudin, 1802), from three localities, namely Modjadjikloof, Mokopane and University of Limpopo, Limpopo Province, South Africa. A total of seven parasite species were collected and identified. They included two nematodes, Camallanus kaapstaadiSouthwell & Kirshner, 1937 and Batrachocamallanus slomei (Southwell & Kirshner, 1937), a monogenean, Protopolystoma xenopodis (Price, 1943), a cestode, Cephalochlamys namaquensis (Cohn, 1906), a protozoan, Trichodina xenopodosFantham, 1924, two digeneans, Progonimodiscus doyeri Ortlepp, 1926 and Dollfuschella rodhainiVercammen-Grandjean, 1960. The most common and abundant parasite species by far were Cm. kaapstaadi, B. slomei and Cp. namaquensis, with Cm. kaapstaadi, B. slomei present in all localities. Trichodina xenopodos was a rare species, only present in host populations from Modjadjiskloof. Modjadjiskloof had the highest species richness (all seven parasite species) followed by Mokopane (five parasite species) and University of Limpopo (3 parasite species). There were also higher infection levels (prevalence and mean intensity) of Cm. kaapstaadi, B. slomei, Cp. namaquensis and Pt. xenopodis in hosts from Modjadjiskloof while Pd. doyeri and D. rodhaini infection levels were greater in Mokopane. The variability between localities shows that parasites with heteroxenous life cycles are more strongly associated with more pristine habitats. The variability in calculated indices (prevalence and mean intensity) also suggests that the occurrence of some of the parasites is affected by season, favouring higher infection rates during summer. This suggests that temperature has a direct role in the reproductive and developmental processes of these parasites. Neither length nor sex had an influence on the prevalence or intensity of parasites.

“…Faced with species descriptions that often were incomplete, and the resulting poor understanding of variation in the morphology of the terminal genitalia, Gibson and Bray (1979) were forced to maintain a broad concept of Halipegus. Recent work on halipegines (Hamann, 1986;Kohn et al, 1990;Lunaschi, 1990;Jackson and Tinsley, 1997;Zelmer and Esch, 1999) has facilitated a more narrowly delimited concept of Halipegus that restricts membership to those species lacking genital sacs, permanent sinus organs, and well-developed hermaphroditic ducts.…”
