Utah Chub ( Gila atraria ) from the latest Pleistocene Gilbert Shoreline, West of Corrine, Utah

A bulk sampling of gastropods collected near Great Salt Lake, Utah, Revealed several fish bones of Gila atraria (Girard). The early date of this find, coupled with the relationship of the Gilbert lake transgression and successive regression of approximately 11,000 years B.P., reveals a death assemblage induced by a series of saline inundations into the freshwater paludal environment.     

Parasites of mottled sculpin, Cottus bairdi Girard, from five locations in Utah and Wasatch counties, Utah

Between 1983 and 1985, 97 mottled sculpin, Cottus bairdi Girard, were examined from five collection sites in central Utah for parasites. Eight different species of parasites were observed, representing seven genera of Protozoa ( Plistophora, Myxidium, Myxobolus, Ichthyophthirius, Trichodina, Apiosoma, Eimeria ) and one genus of Nematoda ( Rhabdochona ). The highest number of parasites was found in sculpin from the Provo River near residential areas, while the lowest number was recorded from Hobble Creek, a nearby pristine area. A complete list of parasites for C. bairdi with literature citations is presented. Each observed parasite is discussed emphasizing pathogenesis to the host.     

Parasites of the woundfin minnow, Plagopterus argentissimus , and other endemic fishes from the Virgin River, Utah

Two hundred woundfin minnows, Plagopterus argentissimus , from four sites along the Virgin River, Utah, were examined on two dates during summer 1985. The foreguts of 211 woundfin and variable numbers of other fishes from the Virgin River near Beaver Dam Wash, Arizona, and Mesquite, Nevada, were examined for cestodes on four dates throughout 1979. Seven parasites were found in P. argentissimus: Posthodiplostomum minimum (metacercariae), Diplostomum spathaceum (metacercariae), Bothriocephalus acheilognathi, Gyrodactylus sp., Lernaea cyprinacea, Trichodina sp., and Ichthyophythirius multifiliis . Fungal infections were noted on two fish during the study. Seventeen Virgin River roundtail chub, Gila robusta seminuda, were examined from two of the four sites in 1985 and 64 specimens from Beaver Dam Wash were examined in 1979. Gila robusta seminuda was infected with Posthodiplostomum minimum (metacercariae) and Bothriocephalus acheilognathi, the Asian fish tapeworm. This cestode probably gained entrance into the ichthyofauna of the Virgin River from red shiners, Notropis lutrensis, and has the potential of being very detrimental to the endemic and endangered fishes of the Virgin River. Parasite loads were correlated with water quality and habitat disturbance, with highest number and frequency occurring in "disturbed" sites. Low river flows and increased total dissolved solids appear to be associated with a higher parasite frequency and mean number in fishes of the Virgin River. These data represent the first known published records for parasites of the woundfin minnow and Virgin River roundtail chub.     

New mites from the Yampa Valley (Acarina: Cryptostigmata: Oribatulidae, Passalozetidae)

A study was made of the soil mites from under different vegetative types near a coal - burning power plant in the Yampa Valley near Hayden, Colorado. The following new species of oribatids were found: Zygoribatula apletosa n.sp., Multoribates haydeni n.sp., Paraphauloppia cordylinosa n.sp., Passalozetes moniles n.sp.       

A review of the genus Talavera Peckham and Peckham, 1909 (Araneae,Salticidae)

The species of the Holarctic jumping spider genus Talavera are reviewed. Five new species are described: Talavera ikedai sp. n. (¦ §) from Japan and Korea; T. krocha sp. n. (¦ §) from France, Ukraine and Kyrghyzstan; T. parvistyla sp. n. (¦ §) from central and northern Europe; T. sharlaa sp. n. (§) from Tuva; and T. tuvensis sp. n. (¦) from Tuva. A lectotype is designated for Euophrys monticola Kulczy ` ski, 1884. A key to the 14 species now encompassed in this genus, and distributional maps, are provided for all of them. Arguments are given for placing the names Euophrys poecilopus Thorell, 1873 and Attus westringi Simon, 1868 as nomina dubia. Talavera aperta Miller, 1971 is removed from synonymy with both Talavera monticola (Kulczy ` ski, 1884) and Talavera thorelli (Kulczy ` ski, 1891).     

Trachytes kaliszewskii , n. sp. (Acari: Uropodina), from the Great Basin (Utah, USA), with remarks on the habitats and distribution of the members of the genus Trachytes

Trachytes kaliszewskii, n. sp., is described from the Great Basin, Utah, USA. SEM photography illustrates morphological detail. An annotated list is included of currently recognized species of the genus Trachytes , with comments on their distribution and habitat characteristics.     

A new pulvinate Eriogonum (Polygonaceae) from Utah

A new species of pulvinate wild buckwheat, Eriogonum soredium (Polygonaceae, Eriogonoideae) is described from near-barren limestone slopes in the Grampian Hill area near Frisco, Beaver County, Utah. The new species is outwardly similar to E. shockleyi S. Wats, but may be readily distinguished by its glabrous (not pubescent) flowers and fruits, generally smaller leaves, more numerous involucres per head, turbinate (not campanulate) involucres with 5, rarely 4 (not 5 to 10) teeth, and the smaller flowers.     

New species of Corcyrogobius,Thorogobius and Wheelerigobius from West Africa (Teleostei: Gobiidae)

Three new West African species of gobiid fishes are described from the Gulf of Guinea in the tropical eastern Atlantic. These are Corcyrogobius lubbocki sp. nov., Thorogobius rofeni sp. nov. and Wheelerigobius wirtzi sp. nov. Generic features are discussed. T. rofeni, known from only the holotype, was trawled on the upper continental slope, an unusually deep occurrence for a gobiid species.     

A revision of Tachyphron Brown and description of two new genera within the Ariphron group (Hymenoptera: Tiphiidae)

The Australasian genus Tachyphron Brown is revised, and two new New Guinean genera, Deuterothynnus gen. n. and Heligmothynnus gen. n., described. Fifteen species are included in Tachyphron of which seven are described as new (T. aculeatus sp. n., T. athertonensis sp. n., T. mantonensis sp. n., T. neosubfragilis sp. n., T. nigrisetatus sp. n., T. planus sp. n. and T. townsvillensis sp. n.), and a further two, Aelurus comatus Smith and Aelurus fragilis Smith, transferred from Tachynomyia. Thynnus insularis Smith is transferred from Tachynomyia Guérin to Deuterothynnus and a further three new species, D. fulvicentratus sp. n., D. fulvisetatus sp. n. and D. parallelus sp. n. described. Aelurus atratus Cameron and Takyomyia sabronensis Kimsey are transferred from Tachynomyia and Tachyphron, respectively, to Heligmothynnus and a further two new species, H. microspinus sp. n. and H. neoaratus sp. n. described. T. megacephala (Turner) is synonymized with Tachynoides flavopicta (Ritsema) and, therefore, removed from Tachyphron. A key to the Ariphron group of genera is provided, as well as keys to the males of Tachyphron, Deuterothynnus and Heligmothynnus, although the male of D. insularis is associated tentatively with the female holotype only on the basis of collection records. Only the females of D. insularis, T. armidalensis Brown and T. subtriangularus Brown are known, the latter two being described for the first time. Evidence is presented to suggest that T. subtriangularus may be bivoltine in northern Australia.     

New species of the genus Troglocheles (Acari: Prostigmata: Rhagidiidae) from Oetztal Alps,Tyrol, with a key to adult species of the genus

Two new species of rhagidiid mites are described from Oetztal Alps, Tyrol, Troglocheles archetypica n. sp. and T. aggerata n. sp. Their interspecific relationships are discussed and two new species-groups, T. strasseri and T. vornatscheri, are defined. A key to the known adult species of the genus Troglocheles Zacharda is given. Phylogenetic and evolutionary relationships among the known talus- and cave-dwelling species of this genus are briefly outlined, including the possibilities of sympatric versus allopatric speciation.     

Amphiblestrum Gray, 1848 (Bryozoa Cheilostomatida) from the Atlantic-Mediterranean area,with description of a new species

Several species, belonging to the genus Amphiblestrum Gray from the Atlantic-Mediterranean area are discussed. One species is described as new: A. frigidum sp. n., from Lower Pleistocene sediments of the Mediterranean area and from the Recent Northern Atlantic. Systematic affinities among species are discussed together with geographical, ecological and stratigraphical distributions. The climatic-palaeoclimatic significance of some species is stressed: A. lyrulatum and the fossil A. spaeleus and A. intermedius seem to be warm-temperate species whereas all the others are cool, boreal or boreal-arctic species. A. flemingi and A. frigidum sp. n., both Recent Northern Atlantic species known from Würmian submerged sediments and/or Lower Pleistocene outcrops of the Mediterranean area are considered as Boreal Guests.     

New taxa of Rhagidiidae (Acari: Prostigmata) from North America. Part V. Genus Robustocheles Zacharda,with a key to world species of the genus

Six new species of rhagidiid mites from the Nearctic region, Robustocheles (R.) pascuaria n.sp., R. (R.) similis n.sp., R. (Mexia) longichelae n.subgen, n.sp., R. (Lewia) lacustris n. sp., R. (L.) obscuritata n. sp. and R. (L.) spinaea n. sp., are described. Additional morphological data are given for R. infernalis Zacharda and Elliott which is placed in the new subgenus Mexia. A key to adults of the known four subgenera and 15 species of the genus Robustocheles Zacharda of the world is presented.     

A new species of Thelepus from Punta Arenas,Chile, together with a redescription of Streblosoma comatus (Grube) and Thelepus pequenianus Augener (Thelepinae: Terebellidae)

Thelepus comatus (Grube) is redescribed and transferred to the genus Streblosoma. All other records of T. comatus have been examined and described as a new species Thelepus ambitus n. sp. In addition T. pequenianus Augener is redescribed and other records confirmed or transferred to the correct species.     

New species of the rhagidiid genus Foveacheles (Acari: Prostigmata: Eupodoidea) with a lyrifissure-like structure on the chelicerae

Three new species are described: Foveacheles gigantea n. sp., F. halltalensis n. sp. and F. proxima n. sp. Their phylogenetic relationships are discussed. The new gigantea-species group is erected, based on the presence of a lyrifissure-like structure near the base of the fixed digit of the chelicera. A cheliceral lyrifissurelike structure has not been previously observed and described in literature on mites of the superfamily Eupodoidea. The definition of the genus Foveacheles is slightly adapted.     

Some anisakid nematodes from marine fishes of Japan and the North Pacific Ocean

A recent collection of anisakid nematodes from marine fishes from Japan and the North Pacific Ocean comprised a total of seven species of two genera; six of them (Raphidascaroides nipponensis Yamaguti, 1941, Hysterothylacium aduncum aduncum (Rudolphi, 1802), H. auctum (Rudolphi, 1802), H. cornutum (Stossich, 1904), H. marinum (Linnaeus, 1767) and H. physiculi sp. n.) parasitize fishes as adults, whereas one (Hysterothylacium sp.) occurred as larvae encapsulated in the host's abdominal cavity. Hysterothylacium physiculi sp. n. from the intestine of the gadiform fish Physiculus maximowiczi (Herzenstein) (family Moridae) from the western North Pacific (Kamaishi Bay, Honshu) is characterized mainly by shape of the lips, presence of well developed lateral alae starting some distance posterior to base of the lips, a short caecum, and markedly short (324-416mum) spicules. SEM study of R. nipponensis, type species of the genus, did not confirm the presence of dentigerous ridges on the lips. All species are briefly described and illustrated and some taxonomic problems are discussed. Several new host and geographical records are presented.     

A new species of Hydropsyche (Trichoptera: Hydropsychidae) from Utah

Hydropsyche quitchupaha, n. sp. , is described and illustrated based on 3 males collected in Sevier, Emery, and Kane counties, Utah. The upturned posteromesal lobes of tergum X, subapically swollen phallobase, and dorsally depressed phallus apex separate this species from all other members of the Hydropsyche scalaris Group.     

Migrating Mormon Crickets, Anabrus simplex (Orthoptera: Tettigoniidae), as food for stream fishes

Migrating bands Mormon crickets ( Ananbrus simplex ) were observed crossing the Green and Yampa rivers in Dinosaur National Monument, Colorado and Utah, in 1986 and 1987. Swimming crickets were swept downstream and eaten by four- endemic and seven introduced fish species. Included were two endangered fishes, Colorado squawfish ( Ptychocheilus lucius ) and humpback chub ( Gila cypha ). Direct and indirect effects to aquatic food webs associated with application of pesticides for Mormon cricket control may pose a threat to these fishes and to man.     

Two new Oriental genera of Doryctinae (Hymenoptera,Braconidae) from termite nests

Two new genera of the subfamily Doryctinae collected in termite nests are described and illustrated: Termitospathius gen. n. from Sumatra (type species T. sumatranus sp. n.) and Ceylonspathius gen. n. from Sri Lanka (type species C. nixoni sp. n.). It is the first record of the braconids from termite nests in the Old World. The biological features of the Doryctinae species and phylogenetic positions of the new genera are discussed.     

Taxonomic review of a new genus,Diathera gen. n., from Southeast Asia (Lepidoptera,Geometridae: Larentiinae)

Diathera gen. n., a new larentiine genus from central and southwestern China, is described. Three new species are named and described: fluctuata sp. n., metacolorata sp. n. and brunneata sp. n. All species and their genitalia are described and illustrated. A key is provided and the monophyly of the genus and its relationships to the allied taxa are briefly discussed.
