Lower Permian Bryozoa from Ellesmere Island (Canada)

A collection of fossils sampled during the 1898–1902 expedition of theFram to the Canadian Arctic Islands includes abundant bryozoans from the Lower Permian (Artinskian) Great Bear Cape Formation of Ellesmere Island. From this material a new genus with one new species —Nansenopora peculiaris n. gen., n. sp. — as well as three new species —Streblotrypella arctica n. sp.,Phragmophera patricki n. sp. andKallodictyon spinatum n. sp. — are described. Furthermore, the speciesUlrichotrypa ramulosa Bassler, 1929 is reported for the first time from the Lower Permian of the Arctic region.     

Filograna (colonial serpulid worm tubes) from Upper Triassic (Norian) reef boulders of Taurus Mts. (southern Turkey)

Two colonial serpulid worm tubes—Filograna taurica n. sp. and Filograna serialis n. sp.—from the Upper Triassic (Norian) reef boulders occurring in Taurus Mts. (south Turkey) are described. As bafflers, both species of Filograna build microbioherms reaching dimensions of up to 15 cm. Both species were not known either in Turkey or in any other Triassic localities of the Tethyan realm.     

Two new species ofPseudopetigurus (Trilobita) from the Arenig — Llanvirn of South China

Two new species ofPseudopetigurus are described from northern Hunan Province, China.P. deprati n. sp. is abundant in the upper Zitai Formation (upper Arenig) of Shuanghong, Baiyun, Shimen County, andP. expansus n. sp. occurs throughout the Jiuxi Formation (Arenig — lower Llanvirn) of Panjiazui, Taoyuan County. These formations represent outer shelf facies from the Jiangnan Transitional Belt of the South China Plate, close to the southeast margin of the Yangtze Platform. BothP. deprati andP. expansus show similarities to Upper Ordovician species ofPseudopetigurus recorded from South China. Other species ofPseudopetigurus are known almost entirely from cranidia, but pygidia and librigenae are also described for both new species, and the first known hypostome assigned to the genus is described forP. expansus. These two species are ecologically important members of offshore trilobite faunas during the Arenig — Llanvirn and define the outer shelfPseudopetigurus Association of South China. Despite being a deep-water genus,Pseudopetigurus is biogeographically restricted to the western margin of the Gondwanan craton and neighbouring regions of Baltica.

Subtropical coral-reef associated sedimentary facies characterized by molluscs (Northern Bay of Safaga, Red Sea, Egypt)

Summary The shallow marine subtropical Northern Bay of Safaga is composed of a complex pattern of sedimentary facies that are generally rich in molluscs. Thirteen divertaken bulk-samples from various sites (reef slopes, sand between coral patches, muddy sand, mud, sandy seagrass, muddy seagrass, mangrove channel) at water depths ranging from shallow subtidal to 40m were investigated with regard to their mollusc fauna >1mm, which was separated into fragments and whole individuals. Fragments make up more than 88% of the total mollusc remains of the samples, and their proportions correspond to characteristics of the sedimentary facies. The whole individuals were differentiated into 622 taxa. The most common taxon,Rissoina cerithiiformis, represented more than 5% of the total mollusc content in the samples. The main part of the fauna consists of micromolluscs, including both small adults and juveniles. Based on the results of cluster-, correspondence-, and factor analyses the fauna was grouped into several associations, each characterizing a sedimentary facies: (1) “Rhinoclavis sordidula—Corbula erythraeensis-Pseudominolia nedyma association” characterizes mud. (2) “Microcirce sp.—Leptomyaria sp. association” characterizes muddy sand. (3)”Smaragdia spp.-Perrinia stellata—Anachis exilis—assemblage” characterizes sandy seagrass. (4) “Crenella striatissima—Rastafaria calypso—Cardiates-assemblage” characterizes muddy seagrass. (5) “Glycymeris spp.-Parvicardium sueziensis-Diala spp.-assemblage” characterizes sand between coral patches. (6) “Rissoina spp.-Triphoridae —Ostreoidea-assemblage” characterizes reef slopes. (7) “Potamides conicus—Siphonaria sp. 2—assemblage” characterizes the mangrove. The seagrass fauna is related to those of sand between coral patches and reef slopes with respect to gastropod assemblages, numbers of taxa and diversity indices, and to the muddy sand fauna on the basis of bivalve assemblages and feeding strategies of bivalves. The mangrove assemblage is related to those of sand between coral patches and the reef slope with respect to taxonomic composition and feeding strategies of bivalves, but has a strong relationship to those of the fine-grained sediments when considering diversity indices. Reef slope assemblages are closely related to that of sand between coral patches in all respects, except life habits of bivalves, which distincly separates the reef slope facies from all others.     

Two new species of <Emphasis Type="Italic">Paraliparis</Emphasis> (Scorpaeniformes: Liparidae) from the Ross Sea (Antarctica)

Liparidae from stomachs of Antarctic toothfish Dissostichus mawsoni Norman, 1937 (Nototheniidae) caught in the Ross Sea (Pacific sector of Antarctica) have been identified. Two new species of deep-water liparids of the genus Paraliparis Collett, 1879—P. caninus sp. nov. (at a depth of 1182–1651 m) and P. vipera sp. nov. (1700 m)—were described. Both species that turned out to be most similar to P. neelovi Andriashev, 1982, from the Kerguelen area (the Indo-Oceanic sector of the South Ocean) are combined with it into a species group “P. neelovi.” According to meristic characters, pattern of dentition, and the size of gill opening, species of “P. neelovi” are close to the species group “P. copei.” In collections from a depth of 1700 m, also two individuals of P. andriashevi Stein et Tompkins, 1989, known previously from only two types from the northern boundary of the Ross Sea were found. The new finding supports species validity and extends the known limits of its range. The wide distribution of bathybenthal Paraliparis having low fecundity and leading a near-bottom mode of life can be explained by the presence of mesopelagic juveniles and their dispersal via currents.     

Hypergastromyzon eubranchus,a new species of gastromyzontin loach (Homalopteridae) from Sarawak

Hypergastromyzon eubranchus sp. nov. is described from the Lupar basin of Sarawak, Malaysian Borneo. It differs from the only other known species ofHypergastromyzon, H. humilis, from the Kapuas basin of western Borneo, in having a very large gill opening instead of a greatly reduced one, 23–25 instead of 28–30 branched pectoral fin rays, and pelvic fins incompletely rather than completely united to each other posteriorly.     

Silurian Leptaeninae (Brachiopoda) from Gotland, Sweden

Strophomenid brachiopods belonging to the generaLeptaena andLepidoleptaena are described from the uppermost Llandovery — Ludlow succession of Gotland, Sweden. In Gotland,Lepidoleptaena comprises the single speciesL. poulseni, andLeptaena includes four species:L. rhomboidalis, L. sperion, L. depressa andL. parvirugata n. sp.L. depressa shows a considerable amount of morphological variation, which is recognised in the two new subspeciesLeptaena depressa visbyensis n. ssp. from the Llandoverian — Wenlockian Visby Formation, andL. depressa lata n. ssp. from the mid-Wenlockian Slite Group. The distribution of the different species is largely substrate-dependent, withLeptaena rhomboidalis andLepidoleptaena poulseni adapted to high-energy environments with firm substrates, whereas the remaining species preferred fine-grained substrates in low-energy environments.      

Taxonomic review and key to European Ichneumon flies (Hymenoptera, Ichneumonidae), parasitoids of gall-forming sawflies of the genera Pontania Costa, Phyllocolpa Benson, and Euura Newman (Hymenoptera, Tenthredinidae) on willows: Part I

Extensive material on parasitoids of the family Ichneumonidae reared from gall-making sawflies on Salix is identified. The general host—parasite list includes 75 species of hosts—Pontania (40 spp.), Phyllocolpa (21 spp.), Euura (14 spp.), their food plants (33 species of Salix), and their parasitoids of the family Ichneumonidae; many data on hosts and parasitoids are recorded for the first time. The complex of ichneumonids on gallforming sawflies is composed of about 45 species belonging to 15 genera of 6 subfamilies. The annotated list of about 30 species of ichneumonids (except for species of Saotis) reared from gall-making sawflies is given with data on the literature, studied material, distribution, and hosts. Two new species Anoncus gallicola sp. n. and Rhinotorus brachycerus sp. n. are described. A key to the species of the Ichneumonidae of this complex is given.     

Species of <Emphasis Type="Italic">Neohaliotrema</Emphasis> Yamaguti, 1965 (Monogenea: Ancyrocephalidae) from the pomacentrid <Emphasis Type="Italic">Abudefduf vaigensis</Emphasis> (Quoy &; Gaimard) off Pulau Langkawi,Malaysia, with a revised diagnosis of the genus and a key to its species

Four new and one unidentified species of Neohaliotrema Yamaguti, 1965 were obtained from the gills of the Indo-Pacific sergeant Abudefduf vaigensis (Quoy & Gaimard) off Pulau Langkawi, Malaysia. The five species, N. malayense n. sp., N. bombini n. sp., N. andamanense n. sp., N. parvum n. sp. and an unidentified Neohaliotrema sp. (similar to N. macracanthum Zhukov, 1976), are described and distinguished based mainly on features of the haptor. Species of this genus are divisible into two groups, the ‘maomao group’, with two pairs of morphometrically modified ‘marginal’ hooks and a fenestrated haptor, and the ‘gracile group’, with morphologically similar marginal hooks and an entire haptor. With the exception of N. bombini n. sp., the species described fit within the ‘maomao group’. It is suggested that the more complex Neohaliotrema species of the ‘maomao group’ have modified hooks 1 and 2 on a haptoral ‘isthmus’ between two large apertures, i.e. ‘windows’, whereas the less complex species lacking these features are those of the ‘gracile group’. Neohaliotrema spp. have only a single pair of pigmented eye-spots. A fenestrated haptor is unique to the Neohaliotrema spp. of the ‘maomao group’. The generic diagnosis of Neohaliotrema is amended to include new data and a key to its known species is presented.     

A new gnetalean pollen genus <Emphasis Type="Italic">Chomsiipites</Emphasis> from cretaceous deposits of the eastern mediterranean

Four species of a new genus, Chomsiipites—Ch. libanicus sp. nov., Ch. pyriformis sp. nov., Ch. dzyubae sp. nov., and Ch. zaklinskaiae (Azèma et Boltenhagen) comb. nov.—are described from the Albian-Cenomanian of western part of Central Lebanon, Eastern Caspian Region, Albian-Turonian of Gabon, and Albian-Senonian of Angola (Equatorial Africa).     

Four New Species of the Feather Mite Genus Vanginyssus Mironov, 2001 (Astigmata: Pteronyssidae) from the Vangas (Passeriformes: Vangidae) in Madagascar

Four new feather mite species of Vanginyssus Mironov, 2001 are described from vangas (Passeriformes: Vangidae), an endemic passerine family from Madagascar: Vanginyssus euryceros n. sp. from the helmet vanga Euryceros prevostii Lesson, V. madagascarinus n. sp. from the blue vanga Cyanolanius madagascarinus (Linnaeus), V. mystacornis n. sp. from the Crossley’s babbler Mystacornis crossleyi (Grandidier) and V.␣orioliae n. sp. from the Bernier’s vanga Oriolia bernieri Geoffroy Saint-Hilaire. A key to the five known species of Vanginyssus is provided.     

Neodiaptomus intermedius n. sp. (Calanoida: Copepoda) from South India

A new species of Neodiaptomus, N. intermedius n. sp. is described and illustrated. It is compared with related species of the strigilipes — physalipus species group.     

A new blind loach, <Emphasis Type="Italic">Oreonectes elongatus</Emphasis> sp. nov. (Cypriniformes: Balitoridae) from Guangxi,China

A new loach, Oreonectes elongatus sp. nov. is described based on collections from Mulun Township, Huanjiang County, Guangxi in China. It is distinguished from its congeners by the combination of the following characters: most elongate body (body depth/SL 8.62–10.68%), blind, a forked caudal fin, obvious adipose dorsal crest and ventral crest; entire body naked and de-pigmented. Although the new species has a similar distribution with O. macrolepis, it can be distinguished by scales (absent in O. elongatus vs. present in O. macrolepis), shape of snout (elongate vs. round), the opposite position of the dorsal and pelvic fins origins (behind vs. front). The new species shares the same possession of dorsal and ventral crests, a forked caudal fin, eyeless, naked body and incomplete lateral line with O. translucens, but can be distinguished from the latter by caudal fin crest (more developed and translucent in O. translucens), longer anterior nostril tube and barbel, extreme of pectoral fin reaching 2/3 of the distance between origin of pectoral and pelvic fins, more vertebrae (4 + 38–39 vs. 4 + 32).     

<Emphasis Type="Italic">Elaeocarpus</Emphasis> for <Emphasis Type="Italic">Flora Malesiana</Emphasis>: new taxa and understanding in the <Emphasis Type="Italic">Ganitrus</Emphasis> group

The Ganitrus group of Elaeocarpus L. (incl. Elaeocarpus Sect. Ptilanthus Schltr.) as found in Malesia is examined and some understanding reached. The group is more complex and speciose in eastern Malesia, especially in Papuasia (with the Philippines, Sulawesi and Maluku somewhat less rich) than in western and central Malesia. E. angustifolius Blume (syn. E. ganitrus & E. sphaericus auctt. mult.) — the source of the ornamental beads known as rudraksha of eastern commerce, from which malas or rosaries are made — is considered to be very variable in Malesia and probably varies further in the extremes of its range; outside Malesia the Ganitrus group is represented by ‘E. angustifolius s.l.’ only. The following species are recognised: E. altisectus Schltr. with a new subsp. carrii Coode from New Guinea; E. angustifolius Blume; E. avium Coode sp. nov. from New Guinea; E. buderi Coode; E. dolichostylus Schltr. with E. chloranthus treated as var. chloranthus (A. C. Sm.) Coode from New Guinea, with a new var. elliptifolius Coode from the Talaud/Sangihe Is. and a new var. hentyi Coode (replacing and re-interpreting subsp. collinus Coode) from New Guinea; E. fulvus Elmer; E. kaniensis Schltr.; E. ornatus Coode sp. nov. from New Guinea; E. osiae Coode sp. nov. from Bougainville I.; E. ptilanthus Schltr.; E. ramiflorus Merr. and E. trichopetalus Merr. & Quisumb. — a total of 12 species although the last two are perhaps not truly distinct from E. angustifolius. The stone sculpturing is discussed and some useful characters revealed. Attention is drawn to a collection from mid-altitude in Papua New Guinea, inadequately known but probably a new species in this group.     

Molds on house walls and the effect of their chloroform-extractable metabolites on the respiratory cilia movement of one-day-old chicksin vitro

The ciliostatic activity of the chloroform-extractable endo- and exometabolites of 5 strains of filamentous fungi—Alternaria sp.,Aspergillus glaucus group,Aspergillus versicolor, Cladosporium sphœrospermum, Penicillium sp. andUlocladium sp.—isolated from molded walls of a dwelling—on tracheal cilia from 1-d-old chicksin vitro was evaluated. Endometabolites ofAlternaria sp. andA. versicolor and exometabolites ofUlocladium sp. were the most active, these extracts stopped the ciliary movement within 1 d. The results are discussed in relation to the health status of people living in “moldy” dwellings.     

Neoselachians (Chondrichthyes,Elasmobranchii) from the Lower and lower Upper Cretaceous of north‐eastern Spain

Extensive sampling of several Barremian and Albian–Cenomanian levels across the Aguilón, Oliete and Aliaga subbasins of the Iberian Basin, north‐east Spain, yielded abundant material of new or so far poorly known neoselachians. The faunas consist of 16 different species, five of which represent new species and two new genera: Cantioscyllium brachyplicatum sp. nov. , Platypterix venustulus gen. et sp. nov. , Ptychotrygon pustulata sp. nov. , Ptychotrygon striata sp. nov. and Iberotrygon plagiolophus gen. et sp. nov. In addition, teeth of Heterodontus cf. H. carerens, Lamniformes indet., Pteroscyllium sp., Scyliorhinidae indet., Rhinobatos sp., Spathobatis sp., Belemnobatis sp., Ptychotrygon geyeri, Ptychotrygon sp. and Celtipristis herreroi are described. The new family Ptychotrygonidae is defined. The localities comprise palaeoenvironments ranging from lacustrine and shallow lake to open marine settings. Neoselachians are almost completely absent from continental settings in the Barremian, as a result of prevailing freshwater conditions, but became more abundant in marine strata. The Albian–Cenomanian selachian assemblage is the most profuse and diverse of the three assemblages studied. It is dominated by small, benthic and near‐coastal taxa, for instance Cantioscyllium and Ptychotrygon, and contains several new species, including an endemic batoid, Iberotrygon plagiolophus gen. et sp. nov. © 2009 The Linnean Society of London, Zoological Journal of the Linnean Society, 2009, 155 , 316–347.

M. paronostris n. sp.: R=117–128, R V=7–9, spear=55–62 μm, submedian lobes present, larvae with smooth annules; Criconemoides punicus n. sp.: R=75–85, R V=5–7, spear=73–81 μm, larvae with crenate annules: Hemicycliophora siddiqii n. sp.: R=185–198, R V=33–42, spear=57–59 μm, one incisure plus longitudinal lines on the cuticle. ac]19860702     

Two new species of the genusAmblyeleotris (Pisces: Gobiidae) from the Ryukyu Islands,Japan

Two new shrimp-associated gobies,Amblyeleotris yanoi sp. nov. andA. masuii sp. nov. are described on the basis of specimens from Iriomote-jima Island and Okinawa-jima Islands, Okinawa Prefecture, Japan.A. yanoi is distinguished from other members of the genus by the combination of the following characters: 14 anal fin soft rays, 19 pectoral fin rays, 97–103 longitudinal scales, a candle flame-shaped marking on the caudal fin, a very low membrane connecting the pelvic fins and absence of a ventral frenum.A. masuii differs from all other congeners by having 92–97 longitudinal scales, the length of the interpelvic connecting membrane relative to the longest pelvic fin ray (0.43–0.66), black blotches on the sides of the chin, and blue spots on the opercle and preopercle.     

Occurrence of velvet-fishes of the genus <Emphasis Type="Italic">Cocotropus</Emphasis> (Teleostei: Scorpaeniformes: Aploactinidae) in Vietnam waters with descriptions of two new species

For the first time, the genus Cocotropus is recorded from the South China Sea and in the Vietnam fauna. Two new species are described—C. astakhovi and C. eksae spp. n. They are compared in detail with 14 previously known species of this genus. The fauna of velvet-fishes of Vietnam is revised. Previously noted for Vietnam Paraploactis sp. is attributed to C. astakhovi.
