On some Indian species of Aphelinidae,with a description of a new Coccophagus (Hymenoptera: Chalcidoidea)

Summary

The Philippine cruise of the U.S. Fisheries Steamer Albatross 1907–10 collected 61 species of spider crabs from the Philippine Islands bringing the total number of species known from the area to 71; 28 new species were described by Rathbun and the present report records 19 species not previously known from the area; included are nine widespread Indo-west Pacific forms, four previously known from Japan and four Indian Ocean species.

Hyastenus sebae White is renamed H. whitei and the former name is applied to H. oryx A. Milne Edwards. Hyastenus tuberculosus Rathbun is confirmed as a synonym of H. convexus Miers, Platymaia remifera Rathbun is reduced to synonomy with P. wyvillethomsoni Miers and Chorilia sphenocarcinoides Rathbun is transferred to the genus Sphenocarcinus.

The majority of species (51) occur around the central and southern islands of the archipelago and most of these (35 speciesl occur at varying depths on the continental shelf. Twelve species occur intertidally and 21 species are known from depths over 100 fms, some occurring as deep as 800 fms.

The spider crab fauna is clearly part of the Indo-west Pacific, 25 species being widespread ones; 26 species are shared with Japan, 24 with Australia and 31 with the Indian Ocean. However, 20 species appear to be confined to the Philippine Islands. The relationships of the Philippine fauna with that of the rest of Indonesia is not yet clear     

Bats associated with inactive mines in the Great Basin

We surveyed bats using echolocation calls near inactive mines in the western Great Basin from 2003 to 2007. We identified 14 species of bats during our surveys, with Myotis lucifugus and Lasionycteris noctivagans found at 9 sites and Myotis evotis and Tadarida brasiliensis at 7 sites; all other species were found at less than one-half of the sites. Euderma maculatum, a state-protected species in Nevada, was recorded at 2 sites. Our work provides information that will be useful in managing bat habitat, especially with regard to mining activities.     

Wintering bats of the upper Snake River plain: occurrence in lava-tube caves

Distribution and habitat selection of hibernating bats at the Idaho National Engineering Laboratory (INEL) and adjacent area are reported. Exploration of over 30 lava-tube caves revealed that two species, Myotis leibii and Plecotus townsendii, hibernate in the upper Snake River Plain. Five species, M. lucifugus, M. evotis, Eptesicus fuscus, Lasionycteris noctivagans, and Lasiurus cinereus are considered migratory. Myotis leibii and P. townsendii hibernate throughout much of the area, occasionally in mixed-species groups. Myotis leibii uses the dark and protected regions of the cave, usually wedged into tiny pockets and crevices near or at the highest portion of the ceiling. Individuals of P. townsendii may be found at any height or depth in the cave. Temperature appears to be the primary limiting factor in habitat selection. Myotis leibii was found in significantly cooler air temperatures than P. townsendii . Neither species tolerated continuous temperatures below 1.5 C. Relative humidity does not seem to be a significant factor in the distribution or habitat selection of the two species in lava-tube caves.     

Genetic diversity of freshwater crabs (Brachyura: Sesarmidae) from central Jamaica with description of a new species

Jamaica is the only island of the Greater Antilles where freshwater streams are not populated by representatives of the old lineage of freshwater crabs, the Pseudothelphusidae. Instead, a very diverse fauna of endemic sesarmid crabs inhabits freshwater and terrestrial habitats throughout the island, thereby showing complete independence from the sea. They have been reported thriving in bromeliad leaf axils, rock rubble, empty snail shells, caves and mountain streams. Otherwise, the Sesarmidae are typical inhabitants of soft‐sediment littoral habitats like marshes and mangroves. For many years, crabs from Jamaican mountains streams had been considered to belong to a single species, Sesarma bidentatum Benedict . However, recent morphological and molecular studies have shown that crabs from mountain streams of different regions of the island belong to different species. Consequently, four new crab species have been described over the last 10 years. In this study, we give evidence that freshwater streams in central Jamaica also host two different species of crabs. In streams draining to the north we exclusively found the species S. windsor Türkay and Diesel, , while streams draining to the south were inhabited by a closely related but undescribed species of crab. The southern species is here described as new and is referred to as Sesarma meridies sp. n. Morphological and molecular (12S and 16S mtDNA) evidence is provided that allows these two species of freshwater crabs from central Jamaica to be distinguished. The species richness of Jamaican endemic sesarmids thereby increases to 10, which makes the island unique in terms of its diversity of land‐dwelling crabs.     

Records of ascidians from Bahrain,Arabian Gulf with three new species

Fifteen ascidian species were identified from 1 to 12 m depth in coastal waters of Bahrain, Arabian Gulf. Three new species, Aplidium rubripunctum, Didemnum yolky and Symplegma bahraini are described. Four species collected are cosmopolitan. This study increases knowledge of the ascidian fauna of an area for which only sporadic collections have previously been made.     

Helminths of 13 species of microhylid frogs (Anura: Microhylidae) from Papua New Guinea

In an attempt to better document the invertebrate biodiversity of the threatened fauna of Papua New Guinea (PNG), 208 microhylid frogs representing 13 species collected in 2009 and 2010 in PNG were examined for endoparasitic helminths. This study found mature individuals of one species of Digenea (Opisthioglyphe cophixali), adults of two species of Cestoda (Nematotaenia hylae, Cylindrotaenia sp.) and cysticerci of an unidentified cestode species; adults of nine species of Nematoda (Aplectana krausi, Bakeria bakeri, Cosmocerca novaeguineae, Cosmocercella phrynomantisi, Falcaustra papuensis, Icosiella papuensis, Ochtoterenella papuensis, Parathelandros allisoni, Parathelandros andersoni), and one species of Acanthocephala (cystacanths in the family Centrorhynchidae). There was a high degree of endemism among the helminth species infecting the microhylids, with 83% of the species known only from PNG. Yet the helminth fauna infecting Papuan microhylids are generalists with direct life cycles (no intermediate host) that also infect other anuran species. We thus conclude infection is more dependent upon habitat conditions than diet. Twenty-nine new host records are reported.     

Recent species of the Family Candonidae (Ostracoda,Crustacea) from the ancient Lake Biwa,Central Japan

Sampling of Lake Biwa between November 1997 and February 2007 has revealed a diverse Candonidae fauna consisting of 18 species. Eleven are previously undescribed species, belonging to the genera Fabaeformiscandona (nine species), Pseudocandona (one species) and Cypria (one species), and 10 of these are potentially endemic to the lake. In total there are 12 Fabaeformiscandona species in the lake belonging to two sub‐groups based on the number of setae on the mandible palp, the fabaeformis‐group (10 species) and the acuminata‐group (two species). Including the new Fabaeformiscandona species described herein, Lake Biwa is home to 19% of the approximately 62 described living species of this genus known globally. Although, the new Fabaeformiscandona species are potentially endemic, they do not show a microevolutionary pattern similar to that suggested for the Tanganyikan Cyprideis species flock.     

A new species of Aphis from Epilobium in Africa

The microcrustacea of the inshore shallows of 99 standing waters in the Tayside Region of Scotland have been sampled in the years 1977–1980. Analyses of the samples showed that Daphnia magna was present at six sites, more than doubling the number of known sites in Scotland and Daphnia atkinsoni, previously unrecorded in the north of Britain, was found at one site. D. pulex and D. obtusa generally occurred with these species and at all of the sites the water was chemically rich, presumably a result of nesting and roosting birds. The introduction of these species is believed to have resulted from transport by such birds. Such a three-way relationship may represent a dynamic and rapidly-changing situation, the end product being the complete disappearance of the water-body and its associated fauna.     

Ascidiacea (Tunicata) from deep waters of the continental shelf of Western Australia

Seventy‐eight species of Ascidiacea, including 21 new species from deeper waters (about 100 m and occasionally to about 500 m) off Western Australia appear to represent a diverse fauna not previously sampled. The relatively few solitary species taken include two possibly introduced (Styela plicata and S. clava). Large aplousobranch colonies dominate the collections. Aplousobranch species with numerous, small, deeply embedded zooids in massive three‐dimensional, vertical and often branched or stalked inflexible colonies supported by embedded sand (Polyclinindae) or calcareous spicules (Didemnidae) are common. Species with flexible stalks (enabling them to respond to prevailing currents) such as Clavelina meridionalis, Sigillina australis and S. cyanea were not taken often. Some known species (e.g. Synoicum chrysanthemum, and Atriolum tubiporum) previously considered rare were taken at these depths in significant numbers. Other unusual taxa (Pseudodiazona longigona and Condominium spp.) are recorded from new locations but do not appear to be common.     

Three new species and a new record of tenuipalpid mites (Acari: Tenuipalpidae) from Hungary

Three new tenuipalpid species are described and illustrated from Hungary: Cenopalpus cumanicus sp. nov., Cenopalpus adventicius sp. nov. and Tenuipalpus budensis sp. nov. (Acari: Tenuipalpidae). The authors give an account of one new record of Cenopalpus spinosus (Donnadieu, 1875) found on woody host plants, a species that has not previously been recorded in the Hungarian fauna. Additional species encountered during these surveys are: Brevipalpus lewisi (McGregor, 1949), Cenopalpus pulcher (Canestrini and Fanzago, 1876), Pentamerismus oregonensis McGregor, 1949, and Pentamerismus taxi (Haller, 1877).     

Two new species of terrestrial Isopoda (Crustacea,Oniscidea) from Ascension Island

A collection of eight species of terrestrial isopods from lava and cave sites on Ascension Island is described. Two species, Niambia longiantennata (Platyarthridae) and Elumoides coecus (Eubelidae), are described as new. Atlantoscia alceui Ferrara and Taiti (Philosciidae) is considered to be a junior synonym of A. floridana (Van Name) and the genus Ocelloscia Schultz and Johnson of Atlantoscia Ferrara and Taiti. At present the oniscidean fauna known from Ascension Island consists of 13 species.     

Three new mite species of the genus Mediolata Canestrini (Acari,Stigmaeidae) from Turkey and re-description of Mediolata granaria Gonzalez-Rodriguez

Three new mite species of the genus Mediolata Canestrini – Mediolata obtecta sp. nov., Mediolata ozkani sp. nov. and Mediolata turcica sp. nov. – are described and illustrated from Turkey. Mediolata granaria Gonzalez-Rodriguez is a new record for Turkish fauna. A key to the species known from Turkey is provided.     

Re-evaluation of the fossil Phoridae (Diptera)

I re-evaluated the known fossil phorids after re-examining much of the Baltic amber and Dominican amber fauna. Many extant genera reported from Eocene Chinese and Eocene/Oligocene Baltic amber are actually not present; instead there are representatives of relatively primitive stem-group taxa. A new genus and species of fossil phorid, Limulomyia tyche, based on a male and a limuloid female, is described from Baltic amber. Some changes in the taxonomy of amber phorids are proposed: Pseudometopina Disney is synonymized with Metopina Schmitz (new synonymy), Diplonevra meunieri Brues is transferred to the genus Godavaria Brown (new combination), Protophorites fimbriatus Brues is considered a junior subjective synonym of Protoplatyphora tertiaria Brues (new synonymy) and Phalacrotophora tertiara Statz is transferred to the genus Gymnophora (new combination). The oldest confirmed dates for extant phorid genera are given.     

The Australian species of Encarsia Förster (Hymenoptera,Chalcidoidea: Aphelinidae), parasitoids of whiteflies (Hemiptera,Sternorrhyncha, Aleyrodidae) and armoured scale insects (Hemiptera,Coccoidea: Diaspididae)

The species of Encarsia Förster known from Australia are revised. This study is based mainly on material collected over the last 10 years. Ninety‐four species are recognized, including 38 new species, and seven new records for Australia. All species are fully described or diagnosed, and illustrated by microphotographs. Seven new specific synonymies are proposed and two lectotypes are designated. A key to the females of Australian species of Encarsia is provided. The known hosts and distribution are summarized. The diversity of the Australian Encarsia fauna is discussed.     

A new species of Exitomelita (Amphipoda: Melitidae) from a deep-water wood fall in the northern Norwegian Sea

The recently erected amphipod genus Exitomelita (Tandberg et al., 2012) has so far been found only associated with the deep-water hydrothermal vent field “Loki's Castle” in the Norwegian-Greenland Sea. There it was found on the black smoker chimney walls as well as within fields of the tubeworm Sclerolinum contortum in sulphide- and methane-rich sediments surrounding the vent field. A new species has now been found in a large wood fall of pine at 2800 m depth close to this vent field. This group of amphipods is apparently confined to reduced habitats, and our data support the theory that the vent fauna in this area is closely related to fauna found on cold seeps and wood falls in the northernmost Atlantic and Arctic Oceans. Here we present morphological and molecular data and a short discussion of the habitat of the new species, in addition to a comparison with the previously described species of Exitomelita.http://www.zoobank.org/urn:lsid:zoobank.org:pub:2B0B3CC2-AB6A-4006-83BB-182280CB22B8
