Haematozoa of British birds. V. Redescription of Haemoproteus majoris (Laveran) from the great tit Parus major

Summary

Haemoproteus majoris, originally described by Laveran from Parus major in France but hitherto denied specific status, is redescribed from P. major in Great Britain and designated a valid species. H machlolophi de Mello (1935) of P. xanthogenys in India is considered to be a synonym of H. majoris. The occurrence and distribution of haemoproteids in other Paridae is briefly discussed.     

Leucocytozoon toddi in British sparrowhawks Accipiter nisus: observations on the dynamics of infection

Leucocytozoon infection was studied in a breeding population of sparrowhawks Accipiter nisus in the British Midlands. Almost all transmission was apparently ‘vertical’ from adults to young, at the nest site. Parasites largely disappeared from the blood between October and April, reappearing in a ‘spring relapse’ during the nesting season. Infected birds remained infected for life; there was no evidence of reduced longevity in infected birds once they had dispersed from their natal nest site. There was no assortative mating between infected or uninfected males and females. It is postulated that the concentration of birds at the nest site allows transmission by a non-specific vector breeding in the same vicinity. At other times of year the birds are more regularly dispersed and transmission in unlikely to occur.

New species of Streblosoma (Thelepodidae,Annelida) from the Mediterranean Sea: S. pseudocomatus sp. nov., S. nogueirai sp. nov. and S. hutchingsae sp. nov.

ABSTRACT

In the framework of faunistic research conducted along the Apulian coast of Italy, three new species of thelepodid polychaetes are reported: Streblosoma pseudocomatus sp. nov., S. nogueirai sp. nov. and S. hutchingsae sp. nov. The taxonomic position of S. comatus is clarified and emended as Thelepus comatus. The described species are characterised by their C-shaped arrangement of uncini. The species are compared with their closest congeners and a synoptic table is provided for the species of Streblosma with C-shaped tori.

Species of Gyrodactylus von Nordmann, 1832 (Monogenea Gyrodactylidae) from poeciliid fishes,with a description of G. turnbulli sp. nov. from the guppy,Poecilia reticulata Peters

Gyrodactylus bullatarudis Turnbull, 1956 is described from Xiphophorus helleri × X. maculatus hybrids. Specimens from this host were morphologically indistinguishable from material of this species from Poecilia reticulata and P. sphenops, although differences in host specificity were noted. Gyrodactylus turnbulli sp. nov., a member of the G. eucaliae species group, is described from Poecilia reticulata. Gyrodactylus turnbulli has frequently been confused with G. bullatarudis, although the two species are only distantly related. They can be distinguished by differences in the structure of the dorsal bar, which is deeply notched in G. bullatarudis, and by the relative length of the ventral bar processes.     

Terrapotamon gen. nov., a new genus of freshwater crabs from Malaysia and Thailand,with description of a new species,Terrapotamon aipooae sp. nov. (Crustacea: Decapoda: Brachyura: Potamidae)

A new genus, Terrapotamon gen. nov., is established to accomodate two species of freshwater crabs, Potamon abbotti Rathbun, 1898 from southern Thailand, and a new species, Terrapotamon aipooae sp. nov. from West Malaysia. Members of this genus are characterized by their inflated carapaces, very acutely triangular external orbital angles, and structure of their first male gonopods.     

Species of Gyrodactylus von Nordmann, 1832 (Monogenea: Gyrodactylidae) from freshwater fishes in southern England,with a description of Gyrodactylus rogatensis sp. nov. from the bullhead Cottus gobio L.

Eleven species of Gyrodactylus were found infecting five species of freshwater fishes collected from Rogate (West Sussex, England). These were G. arcuatus and G. gasterostei from Gasterosteus aculeatus, G. pungitii from Pungitius pungitius, G. aphyae, G. laevis, G. limneus, G. macronychus and G. minimus from Phoxinus phoxinus, G. pavlovskyi and G. sedelnikowi from Noemacheilus barbatulus and G. rogatensis n.sp. from Cottus gobio. G. (Limnonephrotus) rogatensis is a member of the G. wageneri species group, and can be distinguished from closely related species (G. aphyae, G. pungitii and G. gasterostei) by its relatively long marginal hooks and by the abruptly tapering toes of its marginal hook sickles. Each parasite was collected from a single host species, and each was narrowly site-specific. With the exception of G. rogatensis, all of the gyrodactylids collected at Rogate also occur in Continental Eurasia, suggesting that they colonized Britain with their hosts via the Doggerland land bridge after the Devensian glaciation. This study demonstrates both the potential of Gyrodactylus for studies of parasite-host coevolution, and the need for critical taxonomic analysis of members of the genus.     

Sibling species in the marine pollution indicator genus Pontonema Leidy (Nematoda: Oncholaimidae), with a description of P. mediterranea sp. nov.

Species of the marine nematode genus Pontonema have been found to dominate the macrobenthos under abnormally high conditions of particulate organic enrichment. Populations from organically enriched habitats in six localities (Kiel fjord, Germany; the Garroch Head sewage-sludge dump ground in the Firth of Clyde, Scotland; Cornelian Bay, N.E. England; the Tyne estuary, N.E. England; Sete, N.W. Mediterranean, France; Blanes Bay, N.W. Mediterranean, Spain) have been compared. Multivariate analyses of 16 morphometric characters in males, and 13 in females, shows that each population is significantly different morphologically from every other population. However, there is morphological overlap between the populations, and it is considered pragmatic to recognize three species in this group, based on a few stable morphological characters: P. vulgare (Bastian, 1865) from the Baltic, P. alaeospicula Bett and Moore 1988 from the UK sites, and P. mediterranea sp. nov. from the Mediterranean. P. mediterranea sp. nov. is described. The species were not found to have established sympatry in this study, unlike many other opportunistic taxa from organically enriched habitats, and the significance of this is discussed.     

Primno evansi sp. nov. (Amphipoda: Hyperiidea) from the eastern North Atlantic

A new species of hyperiid amphipod, Primno evansi, is described from samples collected on R.R.S. Discovery Cruise 140, August to September 1983, in the eastern North Atlantic. The genus Primno, which has a wide geographic distribution, is now represented by five species with two of these occurring in the eastern North Atlantic. Primno evansi is closest to P. brevidens.     

The first Hapalotremus Simon, 1903 (Araneae: Theraphosidae) from Argentina: description and natural history of Hapalotremus martinorum sp. nov.

A new species of Hapalotremus Simon, 1903 from northern Argentina is described and illustrated. Hapalotremus martinorum sp. nov. differs from all other congeners by the colour pattern of live specimens. Males differ in the male palpal bulb morphology, with thickened and less curved embolus having a blunt subapical keel and less-developed apical keel. Females differ in the shape of the spermathecae, with the lateral bases more pronounced than the superiors and the upper edge more rounded. Specimens were captured inhabiting short burrows or crevices under stones in high cloud forests. Hapalotremus cyclothorax (Mello-Leitão 1923) is a junior synonym of Homoeomma montanum (Mello-Leitão, 1923), Hapalotremus scintillans (Mello-Leitão 1929) is a junior synonym of Pachistopelma rufonigrum Pocock, 1901, Hapalotremus exilis (Mello-Leitão 1923) and Hapalotremus muticus (Mello-Leitão 1923) are considered species inquirenda.

A new species of hydromedusa from the Antarctic, Rathkea lizzioides sp. nov. is described and illustrated. The species is characterized by its rounded bell-shaped form, being almost as broad as high, the presence of an apical dome and a gastric peduncle, the 4 unbranched oral arms, the number of nematocyst clusters (7 to 18 in specimens 1·5 mm or greater in height), the occasional presence of 1 or more nematocyst clusters near the mouth margin, the 5 to 7 tentacles in each perradial tentacular bulb, the 3 to 5 tentacles in each interradial tentacular bulb, and the ovoid shape of the tentacular bulb. A key to the known species of Rathkea is provided.     

Two new nematodes,Pseudelzalia longiseta gen. nov., sp. nov. and Paramonohystera sinica sp. nov. (Monhysterida: Xyalidae), from sediment in the East China Sea

Pseudelzalia longiseta gen. nov, sp. nov. and Paramonohystera sinica sp. nov. from subtidal sediment in the East China Sea are described. Pseudelzalia is characterized by 6 labial papillae and 10 cephalic setae, cylindrical buccal cavity, elongate (>2 anal body diameter) spicules, and conico-cylindrical tail devoid of terminal setae. It differs from Elzalia by the absence of terminal setae. Pseudelzalia longiseta sp. nov. is 647–853 μm long, has 7–8 μm long cervical setae, 11–14 μm long caudal setae, 25–41 μm long spicules about 2.1–2.7 anal diameter, and pointed tail-tip. Paramonohystera sinica possesses 12 cephalic setae, a character found in four congeners: Paramonohystera buetschlii (Bresslau and Schuurmans Stekhoven in Schuurmans Stekhoven, 1935, Paramonohystera pilosa Boucher, 1971, Paramonohystera concinna Lorenzen, 1977 and Paramonohystera halerba Fadeeva and Belogurov, 1987. It differs from P. buetschlii by shorter body (933–1023 μm versus 2000–2200 μm); from P. pilosa by the much shorter spicules (79–88 μm versus 167 μm) and narrower head (13–16 µm versus 32 µm); from P.concinna by smooth cephalic setae (versus segmented); and from P. halerba by the absence of two rows of setae on the ventral side of the tail (versus present). Based on the evaluation of nominal species, we recognize 14 valid species and provide an emended diagnosis and a tabular key for Paramonohystera.
