Polystoma fuscus n. sp. (Polystomatidae) from the common spadefoot Pelobates fuscus (Pelobatidae) in Bulgaria

Polystoma fuscus n. sp. (Polystomatidae, Polystomatinae) is described from the urinary bladder of Pelobates fuscus (Pelobatidae) in Bulgaria. Its general morphology is similar to that of other members of the genus but distinguished from them by the underdeveloped hamuli similar to the larval hamular primordia. The new species is also differentiated from the members of the genera of the subfamily Polystomatinae described without hamuli.     

Polystomatidae (Monogenea) of Anura in southern Africa: Polystoma testimagna n. sp. parasitic in Strongylopus f. fasciatus (Smith, 1849)

Polystoma testimagna n. sp. is described as a new species of the Polystomatidae, parasitic in the urinary bladder of the striped stream frog Strongylopus f. fasciatus collected in the Vernon Crookes Nature Reserve, Natal, South Africa. Parasite prevalence was found to be 50.0% and 27.7% in two successive years, and the mean intensity was 1.5 and 1.6, respectively. The species occurs together with another Polystoma species in the same water body and within one kilometre from a third species. Aspects of host specificity are discussed and data on the ecology and distribution of the host presented.     

Polystoma macrocnemis n. sp. (Monogenea: Polystomatidae) from the Iranian longlegged wood frog Rana macrocnemis (Ranidae) in Turkey

Polystoma macrocnemis n. sp. (Polystomatidae) is described from the urinary bladder of Rana macrocnemis (Ranidae) in Turkey. Its general morphology is similar to that of other members of the genus, but it is distinguished from closely related species by numerical parameters of the hamuli and also by its host species and geographical range.     

Polystomatidae (Monogenea) of African Anura: Polystoma dawiekoki n. sp. parasitic in Ptychadena anchietae (Bocage)

Polystoma dawiekoki n. sp. is described as a new species of the Polystomatidae parasitic in the urinary bladder of the plain grass frog Ptychadena anchietae. This parasite was collected at Mkuze town and Mkuze Game Reserve in northern Kwazulu-Natal Province, in the Kruger National Park in Mpumalanga Province, South Africa, and at Bulwa in Tanga Province, East Usambara Mountains, Tanzania. It is distinguished from other African Polystoma species by a combination of characters, including the body size, size and shape of marginal hooklets and the haptor length to body length ratio. The presence of adult, as well as subadult, parasites in the same individuals, as is known for Eupolystoma, represents a significant evolutionary departure from the pattern of transmission typical of Polystoma in most of the other anuran hosts.     

Polystomatidae (Monogenea) of southern African Anura: Polystoma claudecombesi n. sp. parasitic in Rana angolensis Bocage

Polystoma claudecombesi is described as a new species of the Polystomatidae (Monogenea) parasitic in the urinary bladder of the anuran host Rana angolensis. This parasite was collected at three localities in South Africa, namely Vernon Crookes Nature Reserve in Natal province, Witsieshoek Mountain Resort in the north-eastern Orange Free State and Bovenste Oog in the province of Transvaal. It is the largest African polystome described to date. Prevalence at Vernon Crookes Nature Reserve was 4.0% and 2.7% in two successive years, with a mean intensity of 1.0 (n=25 and 36, respectively). One of the two R. angolensis from Witsieshoek was infected with 5 parasites. The diversity and distribution of southern African polystomes is also discussed.     

Syntopic occurrence of new species ofPolystoma andMetapolystoma (Monogenea: Polystomatidae) inPtychadena porosissima in South Africa

Polystoma sodwanensis n. sp. andMetapolystoma porosissimae n. sp. are described as new species of the Polystomatidae parasitic in the urinary bladder of adultPtychadena porosissima collected in northern Natal, South Africa. Of 26 frogs examined, 11 host individuals were infected with one of the two parasite species, while in five both parasite species occurred. This is the first record of two different genera of polystomatids occurring together in one host species and the first record ofMetapolystoma in South Africa. The exceptional nature of the reported double infection is discussed in terms of host specificity within the Polystomatidae. Relevant information is given on the ecology and distribution of the host,Ptychadena porosissima.To whom correspondence should be addressed.     

Morphology and molecular characterization of Polystoma goeldii n. sp. (Monogenea,Polystomatidae) parasite from the urinary bladder of Physalaemus ephippifer (Steindachner) (Anura,Leptodactylidae)

Polystomatid flatworms of amphibians are represented in the Neotropical realm by species of Mesopolystoma, Nanopolystoma, Parapseudopolystoma, Polystoma, Riojatrema and Wetapolystoma but only species of Polystoma are known from Brazil, namely Polystoma cuvieri, P. knoffi, P. lopezromani and P. travassosi. During a survey of monogeneans infecting amphibians in the north-eastern region of Pará State, the Cayenne Caecilian Typhlonectes compressicauda was found to be infected with Nanopolystoma tinsleyi and the Veined Tree Frog Trachycephalus typhonius was found to harbor Polystoma lopezromani. A yet unknown species of Polystoma was also encountered in the urinary bladder of the Steindachner's Dwarf Frog, Physalaemus ephippifer. This new species, which is the second species reported from Physalaemus spp., is described herein as Polystoma goeldii n. sp. and its life cycle is also illustrated. The new species can be distinguished from Polystoma spp. from other neotropical realm by a combination of characteristics, including hamuli morphology, outer/inner hamuli length ratio, haptor/total body length ratio, genital bulb/total body length ratio, genital spine number and COI molecular characters.     

Polystoma cuvieri n. sp. (Monogenea: Polystomatidae), a parasite of the urinary bladder of the leptodactylid frog Physalaemus cuvieri in Paraguay

A new species of polystomatid monogenean, Polystoma cuvieri, is described from the urinary bladder of the leptodactylid frog Physalaemus cuvieri Fitzinger in Paraguay. This new species possesses a reticulated intestine and hamuli of about 350 microns long. The closest species is Polystoma napoensis Vaucher, 1987, described from Osteocephalus spp. in Ecuador. The Paraguayan material is distinguished by the blade size of the hamuli. The hamuli blades appear to be useful in Polystoma systematics.     

Polystoma nacialtuneli n. sp. (Monogenea: Polystomatidae) from the eastern spadefoot, Pelobates syriacus (Pelobatidae) in Turkey

Polystoma nacialtuneli n. sp. is described from the urinary bladder of the eastern spadefoot, Pelobates syriacus from Turkey. This is the fifth polystome species known from Turkey and the third species in Pelobates. We show that this new parasite species can be distinguished from other polystome species in the area by a combination of characteristics, including parasite size and the shape and size of the hamuli. Polystoma pelobatis from Pelobates cultripes has a pair of well-developed hamuli, while P. fuscus from Pe. fuscus characteristically has a pair of underdeveloped hamuli barely larger than the marginal hooklets. Polystoma nacialtuneli n. sp. has well-developed hamuli that vary significantly in shape. Phylogenetic relationships of P. nacialtuneli n. sp. within Polystoma, supplemented with molecular divergences estimated from internal transcribed spacer 1 (ITS1) sequences, indicate that they are well separated from their closest relatives, i.e. P. fuscus and P. pelobatis from Pe. fuscus and Pe. cultripes, respectively.

Renewed sampling of inland aquatic habitats in southern Africa yields two novel freshwater crab species (Decapoda: Potamonautidae: Potamonautes)

A recent survey of the freshwater streams of the Mecula and Yao mountains in the Niassa province of Mozambique resulted in the discovery of a new freshwater crab species. This species is genetically and morphologically distinct from described species from Mozambique or its neighbouring countries, and is described as P otamonautes bellarussus sp. nov. In addition, a new semi‐terrestrial burrowing freshwater crab P otamonautes flavusjo sp. nov. from the Highveld of the Mpumalanga province in South Africa is described based on unique genetic and morphological characters. The phylogenetic affinities of the two new species in relation to the described eastern and southern African Potamonautes species is determined and the biogeographic implications are discussed. © 2014 The Linnean Society of London     

Revision of New Zealand Orthotylinae (Insecta: Hemiptera: Miridae)

Abstract

Six genera and 11 species of Orthotylinae are now known from New Zealand. Zanchius Distant is newly recorded. One new genus, Tridiplous, and seven new species of endemic New Zealand Orthotylini are described and illustrated. Four new species are described in Tridiplous: T. burrus, T. parvapiatus, T. penmani, and T. virens, and three new species are described in Zanchius: Z. ater, Z. rubicrux, and Z. totus. Keys are provided to identify New Zealand taxa of the tribes of Orthotylinae, genera and species of Halticini, genera of Orthotylini, and species of Tridiplous and Zanchius. The bugs are illustrated with colour habitus photos, and drawings including male and female genitalia. Economic importance is discussed.     

Some American Austrolimnius (Coleoptera: Elmidae)

A key is given to the North American species of Austrolimnius, one of which is described as new. A new species from Venezuela is described, and new locality records in North and South America are listed for previously described species.     

Two new British species of Halticoptera (Hymenoptera: Chalcidoidea,Pteromalidae)

The female of a new species of Halticoptera is described from a single specimen from Britain, and the male and female of a second new species are described from material from Britain and Czechoslovakia. Halticop-terina triannulata is recorded from Britain for the first time.     

A new species and new records of lithodid crabs (Crustacea: Decapoda: Lithodidae) from the Crozet and Kerguelen Islands area (Subantarctica)

Four species of lithodid crabs from waters (240–2,005 m) in the Crozet and Kerguelen Islands area were studied. One new species, Neolithodes duhameli, is described. Three other species, N. capensis Stebbing, Paralomis anamerae Macpherson and P. birsteini Macpherson are reported for the first time from these localities. The new species, N. duhameli (620–1,500 m), is the fourth representative of the genus in Subantarctic waters and belongs to the group of species possessing a carapace, chelipeds and walking legs covered with numerous spinules or spiniform granules in addition to spines. However, the new species is distinguishable from others in the genus by the long, strong spines on the carapace and pereiopods. The finding of two species of Paralomis clearly extends their geographic ranges in the Southern Ocean: P. anamerae was previously known only in waters of the Falkland Islands and the circumpolar distribution of P. birsteini is supported. The observation of N. capensis also extends its previously described range from South Africa, in the Cape region, to Subantarctic waters. As a result of this study, 14 species of the family Lithodidae are now known from Antarctic and Subantarctic waters; and most can be considered endemic to these waters.     

Parasitic copepods (Copepoda: Siphonostomatoida) from deep-sea and mid-water fishes

The stages in the metamorphosis of the pennellid Cardiodectes medusaeus (Wilson) are described from mid-water fishes in the Indo-Pacific. The earliest metamorphic stage was found within the body cavity of the second host and indicates a double origin for the frontal processes of the cephalic holdfast in this species. A new species of Lophoura (family Sphyriidae) is described from a single female taken from a deep-water synaphobranchid eel caught in the North Atlantic. The new species, L. simplex, is characterised by the lack of any neck processes. Another sphyriid, Periplexis lobodes Wilson, is reported for the second time. It was found on a deep-sea alepocephalid belonging to the genus Rouleina in Fijian waters.     

A new species of Schoutedenichia Jadin & Vercammen-Grandjean, 1954 from Madagascar and a re-description of S. dutoiti (Radford, 1948) from South Africa (Acariformes: Trombiculidae)

A new chigger mite species, Schoutedenichia microcebi n. sp. is described from the grey mouse lemur Microcebus murinus (J.F. Miller) from Madagascar. The new species is closely related to S. dutoiti (Radford, 1948), a species described from a single specimen collected on a rodent in South Africa. Examination of the holotype and new material on S. dutoiti from South Africa enabled us to re-describe this species and provide new data on its hosts and geographical distribution.

     

Neobrachiella kabatai n. sp. (Copepoda: Lernaeopodidae) parasitic on Isacia conceptionis (Cuvier) (Osteichthyes: Pomadasyidae) from Peruvian waters

Neobrachiella kabatai n. sp., parasitic on the pomadasyid fish Isacia conceptionis (Cuvier) from the Peruvian central coast, is described and illustrated. The new species differs from other species of Neobrachiella in a combination of characters, including the number of trunk posterior processes and the trunkcephalothorax length ratio.     

Petraliellidae Harmer, 1957 (Bryozoa: Cheilostomata) from Queensland,Australia

Several species of the family Petraliellidae were first described from the coast of Queensland, including the type species of Sinupetraliella, S. litoralis. These species are redescribed from type, or topotype specimens, and include Petraliella concinna, which has not been certainly found since its introduction in 1891; lectotype material is designated for P. buski and P. magna. Six other species are described from Queensland, P. crassocirca, P. dentilabris, P. dorsiporosa, Mucropetraliella bennetti, M. serrata and M. tuberosa. The species Mucropetraliella tuberosa is a new addition to the Queensland fauna and is described and illustrated here for the first time since its introduction in 1884. The characters of the family Petraliellidae are briefly discussed and the genera to which the Queensland species are assigned is reviewed. A taxonomic key to the ten Queensland petraliellid species described is also provided.     

Bambusicolous fungi in Japan (5): three species of Tetraploa

Three species of Tetraploa collected from Sasa, or bamboos, are described and illustrated. Among them, T. curviappendiculata on Sasa kurilensis and T. longissima on Pleioblastus chino are compared with hitherto known species and described as new species. In the nomenclature, T. javanica is substituted for T. biformis, formerly reported from the dead bark of a broad-leaved tree in Japan, as a correct name.
