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.

The Caprellidea (Crustacea, Amphipoda) from Western Australia and Northern Territory, Australia

The caprellidean fauna of Western Australia and Northern Territory, Australia, is investigated here. The study reports 26 species in 19 genera. Six new species (Aciconula australiensis n. sp., Caprella traudlae n. sp., Pseudaeginella vaderi n. sp., Orthoprotella nana n. sp., Pseudoprotella soela n. sp. and Pseudoprotomima grandimana n. sp.) are described as new for Science. Lateral view figures of all the species, together with a key to species level, are also provided.     

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.     

New Asellota from the Antarctic deep sea (Crustacea, Isopoda, Asellota), with descriptions of two new genera

Two new genera, Reductosoma gen.n. (Desmosomatidae) and Desmostylis gen.n. (Desmosomatidae), and five new species are described from the Maud Rise and the Gunnerus Ridgc, Antarctica. Two new species of the Desmosomatidae (Eugerdellatinae and Desmosomatinae) are described: Reduetosoma gunnera gen. et sp.n. and Desmosoma hesslera sp.n.; one species of the Munnopsidae (Eurycopinae), Disconectes colernuni sp.n.; and two species of the Macrostylidae from the Antarctic deep sea, Desmostylis obscurus gen. et sp.n. and Macrostylis sarsi sp.n. Comments on the phylogeny and zoogeography are given.     

New species of Myxosporea from frogs and resurrection of the genus Cystodiscus Lutz, 1889 for species with myxospores in gallbladders of amphibians

Two new myxosporean species in the gallbladders of frogs have recently spread across eastern Australia and cause disease. Cystodiscus axonis sp. n. and Cystodiscus australis sp. n. are species of Myxosporea (Myxozoa) identified from a range of Australian frogs and tadpoles including the introduced Cane toad (Rhinella marina). The new species are defined by their distinct genetic lineage, myxospore morphology and ultrastructure of the pre-sporogonic development. Spores of both species are produced in the gallbladder. Spores of C. axonis sp. n. possess distinct filiform polar appendages (FPA). The pre-sporogonic development of C. axonis sp. n. is within myelinated axons in the central nervous system of hosts, as well as bile ducts of tadpoles. Pre-sporogonic and sporogonic development of C. australis sp. n. is confined to tadpole bile ducts and myxospores of C. australis sp. n. are devoid of FPA. The genus Cystodiscus Lutz, 1889 introduced for Cystodiscus immersus Lutz, 1889 is emended to accompany myxosporean parasites affecting amphibians previously classified in the genus Myxidium sensu lato. A synopsis of described species within Cystodiscus is provided.     

Reductive evolutionary trends in two new cavernicolous species of a new Australian cixiid genus (Homoptera: Fulgroidea)

Abstract A new genus, Undarana gen.n., is established to accomodate six new closely related cixiid species from Queensland, Australia: U.tamborina sp. n.(type species), U.gloriosa sp.n., U.towomba sp.n., U. daybora sp. n., U. rosella sp.n. and U.collina sp.n. Two of the species live in lava tubes in northern Queensland and show different degrees of troglomorphy (reduction of eyes and bodily pigmentation) U.rosella is regarded as being troglophilic (facultative cavernicole), adn U.collina as being troglobitic (facultative cavernicole), and U.collina as being troglobitic (obligatory cavernicole), and it is considered likely that they represent a single invasion into the cave environment. Reductive evolutionary trends displayed by cave-dwelling Undarana species are described, and notes on their ecology and distribution are given. Hypotheses on the factors that might have led to cave-adaption in Undarana species are discussed.     

Axiid collections of the Zoological Museum, Copenhagen, with the description of one new genus and six new species (Axiidae, Thalassinidea, Crustacea)

The collections of the family Axiidae in the Zoological Museum. Copenhagen. were examined: seven genera including one new genus, Eucalastacus gen.n. and 14 Indo-Pacific species containing five species, Eiconaxius farreae, E. weberi, E. sibogae, Axius australiensis and Axiopsis serratifrons ; six new species, Eiconaxius demani sp.n., E. mortenseni sp.n., Bouvieraxius keiensis sp.n., Eucalastacus torbeni sp.n., Axiopsis tsushimaensis sp.n., and Calocarirdes vigila sp.n.; and three uncertain species. Eutrichocheles aff. brocki, Eutrichochelts sp. and Axiopsis sp. Postorlocaris. Sakaiocaris and Ca1listocaris are referred, respectively. as junior synonyms of Bouvieraxius. Spongiaxius and Ambiaxius .     

A contribution to the Dicyrtomidae (Collembola) of Hawaii

Ten new species in three subgenera of Dicyrtoma are described from the Hawaiian Islands. Specimens were received from collections made on Hawaii, Maui, Kauai and Oahu. Species definitions are based on chaetotaxy of head, legs and the circumanal region. In addition, presence or absence of lateral spines (neosminthurid setae) on the parafurcular lobes may assist in grouping species within subgenera. Previous records of dicyrtomids from Hawaii include only one species, Ptenothrix ( Papaairioides ) daubia (Folsom). The following new species are described: Ptenothrix ( Ptenothrix ) hawaiicnaeis sp.n., Ptenothrix ( Papirioides ) kauaiensis sp.n., P. ( Papirioides ) serrata sp.n., Dicyrtoma ( Calvatomina ) sylvestratilis sp.n., D. ( Calvatomina ) brevifibra sp.n., D. ( Calvatomina ) tesselata sp.n., D. ( Calvatomina ) longidigita sp.n., D. ( Calvatomina ) bellingeri sp.n., D. ( Calvatomina ) madestris sp.n., and D. ( Calvatomina ) microdentata sp.n.     

Four new species of Gyrodactylus von Nordmann, 1832 (Monogenea,Gyrodactylidae) on gobiid fishes: combined DNA and morphological analyses

Four Gyrodactylus species parasitising four closely related gobiid species in European coastal waters were studied and compared with G. arcuatus Bychowsky sensu Bychowsky & Poljansky (1953) from Gasterosteus aculatus . These were G. gondae n. sp. from Pomatoschistus minutus and P. lozanoi , G. flavescensis n. sp. from Gobiusculus flavescens , G. arcuatoides n. sp. from P. minutus and G. branchialis n. sp. from P. microps. Combined molecular and morphological analyses, as well as morphometric and statistical methods, were used. The ssrRNA V4 region and the complete ITS rDNA region were sequenced. Genetically the four new species are clearly distinct from G. arcuatus . From a morphological point of view, the haptoral hard parts of G. gondae n. sp., G. flavescensis n. sp. and G. arcuatoides n. sp. are related to those of G. arcuatus, while these parts of G. branchialis n. sp. are different, but related to those of G. quadratidigitus Longshaw, Pursglove & Shinn, 2003. For the latter two species, a new species group is formed. The V4 and ITS sequence analyses, however, indicate a close relationship between G. branchialis and the three G. arcuatus-like species.     

New Antarctic holothurians (Echinodermata) – I. Five new species with four new genera of the order Dendrochirotida

Five new Antarctic species and four new genera of dendrochirote holothurians are described: Caespitugo diversipes gen. et sp.n., Caespitugo citriformis gen. et sp.n., Microchoerus splendidus gen. et sp.n. (all Cucumariidae), Crucella hystirix gen. et sp.n. (Paracucumidae), and Echinopsolus acanthocola gen. et sp.n. (Psolidae). To include Crucella in the Paracucumidae a minor change of the family diagnosis was necessary. This change is discussed. The species were caught on the continental shelf of the southern and eastern Weddell Sea. mainly in depths between 200 and 650m. Their systematic status within their families as well as relationships to representatives of other familes are discussed.

Revision of the Genera Apicalia A. Adams and Stilapex lredale and Description of Two New Genera (Mollusca, Prosobranchia, Eulimidae)

All species that have been described in Apicalia , except the type-species, are transferred to other eulimid genera. Three species earlier included in other genera and four new species are placed in Apicalia , viz. A. angulata sp.n. A, cicatricosa sp.n. A. echinasteri sp.n. (all three Queensland), and A. habei sp.n. (Japan). Those of which the hosts are known are all ectoparasites of asteroids. Two of the seven species previously included in Stilapex are excluded and four species earlier placed in other genera are transferred to Stilapex . The members of the latter genus are parasites of ophiuroids. Tropiometricola gen.n. is erected to include Stilifer sphaeroconcha Habe, a crinoid parasite. Parvioris gen.n. is described with Eulima fulvescens A. Adams as type species. A list of species described in eulimid genera and fitting Parvioris is given. P. australiensis sp.n. (W. Australia), P. blakeae sp.n. (Mauritius), P. mortoni sp.n. (Hong Kong), and P. noumeae sp.n. (New Caledonia) are described. Those species of which the host is known, are all ectoparasites of starfishes.     

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.     

A new genus and four new species of quill mites (Acari: Prostigmata: Syringophiudae) from phasianid birds (Galuformes: Phasianidae)

A new genus and four new species of the quill mites are described. Galliphilopsis gen. n. (G. francolinus sp. n., type species) differs from the closely related Dissonus Skoracki, 1999 by loss of leg setae dGII, the slightly divergent tips of epimeres I and the stylophore constricted posteriorly. Three new species of the genus Galliphilopsis gen. n. and one new species of the genus Mironovia Chirov and Kravtsova, 1995 are described from galliform birds (Phasianidae) collected at the Museum of Natural History, Wroclaw University (Poland): G. lophurus sp. n. from Lophura leucomelanos, G. bochkovi sp. n. from Tragopan sp. and Alectoris barbara, G. francolinus sp. n. from Francolinus levalliantoides, and Mironovia rouloul sp. n. from Rollulus rouloul.

Three New Species of Minoninae (Turbellaria, Proseriata, Monocelididae) from the North Sea, with Remarks on the Taxonomy of the Subfamily

Three new species of Minoninae are described and a new genus is proposed for one of them: Minona degadti sp.n., Duplominona septentrionalis sp.n. and Duploperaclistus circocirrus gen. et sp.n. All three species occur in sublittoral sandy habitats in the Southern Bight of the North Sea, but D. circocirrus has also been found at a littoral station. The taxonomy within the subfamily Minoninae is discussed. Seven genera are considered as valid, and they are briefly diagnosed. " Peraclistus ituipus" sensu Westblad (1952) (= Duplominona westbladi Karling, 1966) is included in the new genus as Duploperuclistus westbladi (Karling, 1966) comb.n.
