Three New Species

The genus Orientodiscus was proposed by Srivastava (1938) for O. jumnai and O. lobatus from a freshwater fish, Silundia gangeticus from India. Recently, Rhode (1963) added O. fernandoi and O. hendricksoni from freshwater turtles, Trionyx spp., from Malaysia. A large number of trematodes belonging to Orientodiscus were collected from freshwater turtles in Aligarh, India. They represent three new species.

The polystomes (Monogenea, Polystomatidae) radiated across semi-aquatic tetrapods including all three amphibian orders, freshwater turtles and the hippopotamus. Prior to this study, phylogenetic analyses revealed that the most diverse and widespread genus, Polystoma, was not monophyletic; a lineage comprising four undescribed species from the bladder of Zhangixalus spp. (Rhacophoridae) in Asia occupied a deep phylogenetic position. Regarding vicariance biogeography and molecular dating, the origin of this lineage is correlated with the breakup of Gondwanaland in the Mesozoic period. Based on a Bayesian analysis of four concatenated genes (18S, 28S, COI and 12S) and morphological evidence, one new genus, Indopolystoma n. gen., and three new species, sampled in Japan and China, are described here: Indopolystoma viridi n. sp. from Z. viridis of Japan, Indopolystoma elongatum n. sp. from Z. arboreus of Japan, and Indopolystoma parvum n. sp. from Z. omeimontis of China. Indopolystoma is unique amongst polystome genera infecting anurans by possessing a small haptor relative to the body size, posteriormost marginal hooklet C1 much bigger than hooklets C2–C8 with conspicuous broad blade and guard and a pair of hamuli lacking a deep notch. Eight species of Asian Polystoma, all from rhacophorids, are transferred as Indopolystoma carvirostris (Fan, Li & He, 2008) n. comb., I. hakgalense (Crusz & Ching, 1975) n. comb., I. indicum (Diengdoh & Tandon, 1991) n. comb., I. leucomystax (Zhang & Long, 1987) n. comb., I. mutus (Meng, Song & Ding, 2010) n. comb., I. pingbianensis (Fan, Wang & Li, 2004) n. comb., I. rhacophori (Yamaguti, 1936) n. comb., and I. zuoi (Shen, Wang & Fan, 2013) n. comb.

Three New Species

Three new species of internal trematodes, Plagioporus serratus sp. nov., Phyllodistomum lysteri sp. nov., and Parastiotrema ottawanensis gen. et sp. nov., are described from Canadian freshwater fish. Plagioporus serotinus Stafford, 1904, is redescribed, and the genus Caudotestis Yamaguti, 1934, is reduced to synonymity with Plagioporus Stafford, 1904. Anallocreadium pearsei Hunter and Bangham, 1932, is considered synonymous with A. armatum McCallum, 1895. The genus Bunoderina Miller, 1936, is reduced to synonymity with Bunodera Railliet, 1896.

Morphological Patterns

Three new species of dactylogyrid monogeneans with three anchors are described: two of them, Eutrianchoratus magnum and E. minutus, from Ophiocephalus obscurus, and Heteronchocleidus ctenopomae from the anabantid Ctenopoma kingsleyae, all from south Ghana.Analysis of the variation in the morphological patterns of the anchors and the bars in the known species of the Heteronchocleidinae suggests gradual specialization from an ancyrocephaliid type with two pairs of anchors to types with three anchors arranged in triangular symmetry.Heteronchocleidinae occur on both ophiocephaliid and anabantiid fish in Southeast Asia as well as in West Africa.

Three New Species

1. Three new species of Myxosoma (Sporozoa, Cnidosporidia, Myxosporidia) are described from freshwater fish of the genus Tilapia in East Africa.2. Two of these, M. heterospora and M. brachyspora spp.nov., inhabit the abdominal viscera: the former was found in 41 of 43 fish examined, while the latter was less common. The third species, M. homeospora sp.nov., produces small oval or circular ‘cysts’ in the subdermal muscle and was found in two very young fish only. Spores resembling those of the first two species were also found in one Haplochromis sp.3. The spores of M. heterospora are roughly ellipsoidal but are very variable in shape, and range from 8·5–17·0 μ in length and 6·3–11·0 μ in breadth; the two anterior polar capsules measure from 2·0–9·5 by 1·5–3·5 μ. Those of M. brachyspora are flattened antero-posteriorly, measuring from 7·0–7·5 μ long and 12·0–13·5 μ broad; their polar capsules are from 2·5–3·8 by 2·3–2·5 μ in size. M. homeospora has ovoid spores with the anterior end narrowed, measuring from 13·5–17·0 by 8·5–11·0 μ; the polar capsules measure 4·0–6·0 by 2·0–4·0 μ.4. It is suggested that M. heterospora, at least, is pathogenic and may play a considerable part in reducing the availability of fish as food in this part of Africa.5. A check-list is given of all species of the genus Myxosoma.I thank Mr R. S. A. Beauchamp (then Director of E.A.F.R.O.) and his staff, also Mr G. Bowser (Manager of TUFMAC), for facilities and assistance in the examination of fish; also Dr G. D. Fryer and Dr D. J. Garrod for sending material to me in London, and Dr P. H. Greenwood for supplying the Haplochromis and checking the names of fish; also Messrs G. D. Lomax and P. E. Nesbitt for the preparation of sections. This work was commenced while I was employed at the East African Trypanosomiasis Research Organization.

Three New Species

Abstract The fauna of bristletails of the genus Lepismachilis Verhoeff, 1910 in Montenegro and Serbia includes only one species L. (Berlesilis) targionii (Grassi, 1887) with 2 + 2 eversible vesicles on abdominal urocoxites II–VI. Three new species of this genus are described: L. (Lepismachilis) prijepolja sp. nov., L. (Lepismachilis) limensa sp. nov. from Serbia, and L. (Lepismachilis) alexandrae sp. nov. from Montenegro. All described new species belong to the species group of the subgenus Lepismachilis s. str. with 2 + 2 eversible vesicles on abdominal urocoxites II–V. Lepismachilis prijepolja sp. nov. differs from L. y-signata Kratochvíl, 1945 and L. notata Stach, 1919 by the color, drawings and ratios of the compound eyes; ratios of sensory field on fore femur of male, number of divisions of ovipositor. Lepismachilis limensa sp. nov. differs from L. hauseri Bitsch, 1974 and L. abchasica Kaplin, 2017 by ratios of paired ocelli, sensory field on fore femur of male; ratios and chaetotaxy of maxillary and labial palps. Lepismachilis alexandrae sp. nov. differs from L. abchasica by the drawings of the compound eyes; ratios of paired ocelli, sensory field on fore femur of male; number of divisions of the parameres and gonapophyses. A list of the Machilidae occurring in Balkan Peninsula is also provided.

Some 2,000 Ptiliidae collected in the North and South Islands of New Zealand in 1983/1984 by Peter Hammond of the Natural History Museum, London, are determined to 34 species, four of which are new to the country. As there are very few previous records, most from the Auckland district of North Island, the Hammond collection provides much new distributional data. The three new species: Nellosana insperatus sp. n., Notoptenidium flavum sp. n., and Notoptenidium johnsoni sp. n., are described and figured; the genus Ptiliodes is moved from Acrotrichinae to Ptiliinae, and Ptenidium formicetorum Kraatz recorded as a new introduction. Information is provided to aid separation of the new species from those previously recorded.
