Pipunculidae (Diptera) from Papua New Guinea: the genera Cephalosphaera, Cephalops and Beckerias

Seven new pipunculid species are described from Papua New Guinea: Cephalosphaera gymne sp.n., C. immodica sp.n. C. wauensis sp.n., Cephalops bifidus sp.n., C. multidenticulatus sp.n., C. papuaensis sp.n., and C. parmatus sp.n. Cephalops argutus (Hardy) is considered as a true Beckerias sp. and thus placed in a new combination: Beckerias argutus. The phylogenetic relationship of the new species is shortly discussed.     

Phylogenetic revision of the Charis cleonus complex (Lepidoptera: Riodinidae)

Abstract.  A revision of the Charis cleonus group of Neotropical riodinid butterflies is presented, including discussions on the taxonomy, biogeography and biology of its species, and illustrations of the adults and male and female genitalia (where known) of all taxa. We recognize twenty-two species, including nineteen new species: C. ariquemes sp.n., C. brasilia sp.n., C. breves sp.n., C. cacaulandia sp.n., C. cuiaba sp.n., C. humaita sp.n., C. ipiranga sp.n., C. iquitos sp.n., C. ma sp.n., C. manicore sp.n., C. manu sp.n., C. matic sp.n., C. maues sp.n., C. negro sp.n., C. palcazu sp.n., C. rocana sp.n., C. santarem sp.n., C. tapajos sp.n and C. tefe sp.n. A cladistic analysis using thirty-six characters of male and female genitalia and external facies generated a single most parsimonious cladogram highlighting the existence of two clades, the major and cleonus subgroups. As each species largely occupies a parapatric range, this cladogram provides the opportunity to reassess historical relationships among areas of endemism in the Amazon basin.     

Taxonomy of European species of Cassagnaudiella and Bourletiella (Collembola, Symphypleona, Bourletiellidae)

The taxonomy of the European members of Cassagnaudiella and Bourletiella (Collembola, Symphypleona, Bourletiellidae) is reviewed. The subgenus Cassagnaudiella Ellis, 197.5 is raised to generic rank with a new definition. Specimens earlier considered to represent a transformed form of Bourletiella radula Gisin, 1946 are referred to Cassagnaudiella , and the application of 'phenotypic neutralization' within the group is Considered erroneous. Four Bourletiella species and six Cassagnaudiella species are described, five of the latter which are new: C. cœnigouensis sp. n., C. luteovernalis sp. n., C. cadiensis sp. n., C. canigouensis sp. n., and C. trichroma sp. n., A key to species is provided.     

New and little-known species of Rhagidiidae from talus ecosystems, in the Czech Republic and Austria

Two new species of mites, Foveacheles (Proxistella) simulata n.sp. and Rhagidia longiseta n.sp., are described, and the little-known Foveacheles (Proxistella) terricola (C. L. Koch) is redescribed. All species were found inhabiting underground spaces in talus formations in the Czech Republic and Austria.     

Palaearctic species of the ichneumon-fly genus Campodorus Förster (Hymenoptera, Ichneumonidae): III. Species with long-haired ovipositor sheath, species with entirely rufous hind tibia, and species with white-banded tibiae

A complex of about 40 Palaearctic species of the genus Campodorus with long haired ovipositor sheath and with entirely rufous or white-banded hind tibia is considered and keyed. Twenty-one new species are described. The species with the pale rufous hind tibia have black hind coxa and trochanters, most of them also have rather long genae and scabrous mesopleura. The majority of these species are distributed in subarctic Siberia: C. yakutator sp. n., C. minutor sp. n., C. arctor sp. n., C. atripes sp. n., C. pequenitor sp. n., C. mordax sp. n., C. lucidator sp. n., C. subarctor sp. n., C. nikandrovskii sp. n., and C. genator sp. n. C. suomi sp. n. is described from northern Finland, C. labytnangi sp. n., from Kola Peninsula, the Polar Ural, and Transbaikalia, and only C. gallicator sp. n., from France (? Alps). The species with a white band on the hind tibia are mostly boreal; most of them have red coxae and trochanters (except for C. sakhalinator sp. n. and C. taigator sp. n.), rather short genae, and granulate mesopleura. In this group, eight new species are described: C. atrofemorator sp. n., C. barbator sp. n., C. sakhalinator sp. n. (all from the southern part of the Russian Far East), C. taigator sp. n. (southern Siberian), C. ciliator sp. n., C. melanopygus sp. n., C. marginator sp. n., and C. boreator sp. n. (European-Siberian).     

Chauhanellus Bychowsky & Nagibina, 1969 (Monogenea) from ariid fishes (Siluriformes) of Peninsular Malaysia

Twelve new species of Chauhanellus Bychowsky & Nagibina, 1969 have been found on six species of ariid from Peninsular Malaysia: Chauhanellus trifidus n. sp., C. digitalis n. sp., C. malayanus n. sp., C. forcipis n. sp. and C. intermedius n. sp. from Arius sagor; C. aspinous n. sp. from Arius venosus; C. caelatus n. sp. from Arius caelatus; C. auriculatum n. sp., C. poculus n. sp. and C. pulutanus n. sp. from Arius maculatus; C. duriensis n. sp. from Arius thalassinus; and C. osteogeneiosi n. sp. from Osteogeneiosus militaris. Some of these Chauhanellus species possess characteristics that are not commonly observed in the genus. C. aspinous n. sp., C. intermedius n. sp. and C. digitalis n. sp. exhibit features found in both Chauhanellus and Hamatopeduncularia: these include absence of spines on the mainpart of the dorsal anchors in C. aspinous n. sp. and C. intermedius n. sp. and presence of haptoral digitation in C. digitalis n. sp. Other features are the five transverse rows of peduncular spines in C. duriensis n. sp., ear-like projections on the anchors in C. auriculatum n. sp., and thin sclerotised plates that partly envelope the ventral anchors in C. forcipis n. sp. Mid-dorsal appendices occur on the dorsal bars of seven of the present species.     

Five new species of Culicoides (Diptera: Ceratopogonidae) of the Nansei Islands.

Five new species of Culicoides of the Nansei Islands are described: C. sasai sp.n. from Amami-oshima Is., C. toshiokai sp.n. from Ishigaki Is., C. iriomotensis sp.n. from Iriomote Is., C. flavipunctatus sp.n. from Yonaguni Is., and C. yaeyamaensis sp.n. from the latter three islands. C. toshiokai sp.n. and C. iriomotensis sp.n. are tree-hole breeders, such as C. dendrophilus Amosova, which is common in similar habitats extending from Okinawa to Honshu.     

Review of the genus Chrysotimus Loew from Tibet (Diptera,Dolichopodidae)

A review of the species of the genus Chrysotimus from Tibet is provided. The following four species are described as new to science: C. motuoensis sp. n., C. tibetensis sp. n., C. xuankuni sp. n., C. zhui sp. n. A key to the eight Tibetan species is presented.     

New and previously described species of Urocleidoides (Monogenoidea: Dactylogyridae) infecting the gills and nasal cavities of Hoplias malabaricus (Characiformes: Erythrinidae) from Brazil

During an investigation of the biodiversity and structure of parasite communities among native populations of the erythrinid fish Hoplias malabaricus (Characiformes) from 7 rivers in Brazil, the following monogenoidean (Dactylogyridae) species were found: Urocleidoides malabaricusi n. sp., Urocleidoides naris n. sp., Urocleidoides cuiabai n. sp., Urocleidoides brasiliensis n. sp., and Urocleidoides eremitus Kritsky, Thatcher, and Boeger, 1986. Specimens considered as a new genus of Dactylogyridae were also found. The new species are mainly distinguished from the other 14 species of Urocleidoides in the general morphology of their copulatory and anchors/bar complexes. These new species and the new dactylogyrid genus are described, as well as supplemental observations and new illustrations of U. eremitus are provided. The present findings expand the known geographical distribution of species of Urocleidoides to southeastern and midwestern Brazil. A high speciation of this genus in the tropics is hypothesized, and it is briefly discussed.

A key to both sexes is provided. All species are restricted to the Afrotropical Region and distributional and known host plant data are given.     

Sponges Collected by the Swedish Deep Sea Expedition

The paper deals with sponges collected in the Atlantic by the Swedish Deep Sea Expedition. The collection contains six species of the genera Malaco-saccus, Chonelasma, heptonema, Asbestopluma , and Chondrocladia , which are well known from the deep-sea. Three new species are described, viz. Asbestopluma quadriserialis sp.n., Chondrocladia al-batrossi sp.n., and C. burtoni sp.n. A survey of the knowledge of the Atlantic deep-sea sponge fauna shows that 118 species are at present known from depths of more than 2 000 m. About 35% of the species were found four or more times, whereas about 47% are known only from the type locality. 63 species were taken more than once, and 50 species are known also from depths of less than 2 000 m.     

Ciliate protozoa in the rumen of Kafue lechwe, Kobus leche kafuensis, in Zambia, with the description of four new species.

The composition of the rumen ciliate fauna in 76 Kafue lechwe inhabiting a limited area in Zambia was surveyed and five genera containing 24 species with 16 formae belonging to the family Ophryoscolecidae were identified. Four new species belonging to Diplodiniinae were recognized and described as Diplodinium lochinvarense n. sp., Diplodinium leche n. sp., Diplodinium zambiense n. sp., and Metadinium ossiculi n. sp. In addition, Ostracodinium gracile form fissilaminatum Dogiel, 1932 was found for the second time and described as Metadinium fissilaminatum n. comb. The species composition was fairly unusual. Seven of the species have been found only in African wild antelopes and these species were found more frequently than cosmopolitan species. There was no evidence of isotrichid species. The average density of ciliates per 1 ml of the rumen fluid was 25.7 x 10(4), and the number of ciliate species per head of host was 10.8.     

Microsporidia of the genus Parahtelohania (Microspora: Amblyosporidae) from blood-sucking mosquitoes of the genus Anopeles (Diptera: Culicidae) from the South of the West Siberia

Five new microsporidian species of the genus Parathelohania have been found in the fat body of blood-sucking mosquitoes collected in various water basins in the South of West Siberia: Parathelohania divulgata sp. n., P. formosa sp. n., P. sibirika sp. n., P. teguldeti sp. n., and P. tomski sp. n. Processes of merogony, sporogony, and ultrastructure of spores was were investigated by means light and electronic microscopy.

In addition, Ostracodinium gracile form fissilaminatum Dogiel, 1932 was found for the second time and described as Metadinium fissilaminatum n. comb. The species composition was fairly unusual. Seven of the species have been found only in African wild antelopes and these species were found more frequently than cosmopolitan species. There was no evidence of isotrichid species. The average density of ciliates per 1 ml of the rumen fluid was 25.7 times 10⁴, and the number of ciliate species per head of host was 10.8.     

A new family, genus, and seven new species of Entodiniomorphida (Protozoa) from the gut of African rhinoceros

This report deals with a group of ciliated protozoa with short ciliary bands found mainly in the cecum of black rhinoceros, Diceros bicornis (linnaeus, 1758), and white rhinoceros, Ceratotherium simum (Burchell, 1817) from southern Africa. A new genus, Rhinozeta, based on the sum total of the characteristics of seven new related species is described. The species described are R. rhinozeta n. sp., R. triciliata n. sp., R. caecalis n. sp., R. addoensis n. sp., R. cristata n. sp., R. multiplatus n. sp., and R. unilaminatus n. sp. The specific features of the new genus make it incompatible with any of the known families of the Order Entodiniomorphida containing the ciliates present in the digestive tract of herbivorous mammals. This merits the creation of a new family, the Rhinozetidae.     

Endoparasites in Sphenomorphus jobiensis (Sauria: Scincidae) from Papua New Guinea with description of three new species

One species of digenean, Zeylanurotrema sphenomorphi n. sp., and 2 nematode species, Meteterakis crombiei n. sp. and Physalopteroides milnensis n. sp., from the intestine of Sphenomorphus jobiensis, are described and illustrated. Zeylanurotrema sphenomorphi n. sp. represents the second species, Meteterakis crombiei n. sp. the 18th species, and Physalopteroides milnensis n. sp. the 19th species assigned to each respective genus. In addition, 1 species of cestode, Oochoristica javaensis; 7 nematode species, Abbreviata oligopapillata, Aplectana macintoshii, Aplectana zweifli, Cosmocerca zugi, Maxvachonia adamsoni, Oswaldocruzia bakeri, Parapharyngodon maplestonei; 1 species of acanthocephalan, Acanthocephalus bufonis; and 1 species of pentastome, Kiricephalus sp., were found. With the exception of Abbreviata oligopapillata, Sphenomorphus jobiensis represents a new host record for each species of endoparasite.

This report deals with a group of ciliated protozoa with short ciliary bands found mainly in the cecum of black rhinoceros, Diceros bicornis (Linnaeus, 1758), and white rhinoceros, Ceratotherium simum (Burchell, 1817) from southern Africa. A new genus, Rhinozeta , based on the sum total of the characteristics of seven new related species is described. The species described are R. rhinozeta n. sp., R. triciliata n. sp., R. caecalis n. sp., R. addoensis n. sp., R. cristata n. sp., R. multiplatus n. sp., and R. unilaminatus n. sp. The specific features of the new genus make it incompatible with any of the known families of the Order Entodiniomorphida containing the ciliates present in the digestive tract of herbivorous mammals. This merits the creation of a new family, the Rhinozetidae.     

A New Family of Entodiniomorph Protozoa from the Marsupial Forestomach, with Descriptions of a New Genus and Five New Species

ABSTRACT. A unique group of entodiniomorph protozoa was found in forestomach contents from quokka ( Setonix brachyurus ), western grey kangaroo ( Macropus fuliginosus ), red kangaroo ( Macropus rufus ) and euro ( Macropus robustus erubescens ). A new genus, Macropodinium n.g., containing five new species, is described. Three species are described from forestomach contents of the quokka: Macropodinium baldense n. sp., Macropodinium moiri n. sp. and Macropodinium setonixum n. sp. A single species, Macropodinium ennuensis n. sp., is described from the red kangaroo and euro. The last species, Macropodinium yalanbense n. sp., is described in forestomach contents from the western grey kangaroo. At least three distinct features in the new genus are incompatible with any of the described families in the order Entodiniomorphida. On this basis, the new family Macropodiniidae has been created.
