Revision of the spider subfamily Gnaphosinae in Israel (Araneae: Gnaphosidae)

Gnaphosid spiders of 6 genera in Israel are revised presenting a relative richness in species and updated information on the Mediterranean spider fauna. Many inhabit the stony deserts of the south or are psammophiles that were detected by pitfall trapping. Minosia, Minosiella and Gnaphosa have never before been reported from Israel. Minosia simeonica sp. n. and the unknown males of M. spinosissima and Minosiella pharia are described. Gnaphosa barroisi is reinstated as a separate species. Berlandina jovia Denis, 1947 is newly synonymized with B. venatrix Dalmas, 1921, while the following B. chopardi Denis, 1955, B. paludani Denis, 1958, B. afghana Denis, 1958 and its subspecies B. a. spinitarsis Denis, 1958, and B. macrostigma Denis, 1966 are new synonyms of B. plumalis (O. P.-Cambridge, 1872) one of the most widely distributed gnaphosids in the Old World. The matching female of Nomisia excerpta and the matching of N. palaestina, each proving a separate species, have been identified, and N. negebensis sp. n. is described. Nomisia marginata (O. P.-Cambridge, 1874) and N. mauretanica Dalmas, 1921 are new synonyms of N. ausserei (L. Koch, 1872), N. verneaui (Simon, 1889) = N. excerpta (O. P.-Cambridge, 1872), and N. soror Dalmas, 1921 = N. palaestina (O. P.-Cambridge, 1872). In Pterotricha, the largest genus of Gnaphosinae in the Middle East, P. levantina sp. n., P. parasyriaca sp. n., P. engediensis and the unknown female of P. dalmasi are described, and the following new synonyms are recognized: P. aegyptiaca Dalmas, 1921 and P. isiaca Dalmas, 1921 = P. conspersa (O. P.-Cambridge, 1872); P. fanatica Dalmas, 1921 = P. lesserti Dalmas, 1921; P. peregrina Denis, 1948 = P. chazaliae (Simon, 1985); P. lentiginosioides Nosek, 1905 = P. kochii (O. P.-Cambridge, 1872). Illustrations of diagnostic characters, records of distribution and pertaining literature are provided for each species.     

Redescription of adult and larva of Colasposoma sellatum Baly (Coleoptera: Chrysomelidae: Eumolpinae): a pest of sweet potato in Australia

The genus Colasposoma Laporte is shown to be represented in Australia by a single species, C. sellatum Baly (= C. barbatum Harold, syn. conf.; = C. regulare Jacoby, syn. nov.). The adult and larva are described and lectotypes designated for C. sellatum and C. regulare. Colasposoma sellatum is recorded from the Northern Territory, northern Queensland and New Guinea. This species is a pest of Ipomoea batatas (sweet potato) in northern Queensland, where the adults damage stems and foliage and larvae may cause considerable damage to tubers. Its pest status is assessed and control measures discussed.     

Addenda to the insect fauna of Al-Baha Province,Kingdom of Saudi Arabia with zoogeographical notes

The first list of insects (Arthropoda: Hexapoda) of Al-Baha Province, Kingdom of Saudi Arabia (KSA) was published in 2013 and contained a total of 582 species. In the present study, 142 species belonging to 51 families and representing seven orders are added to the fauna of Al-Baha Province, bringing the total number of species now recorded from the province to 724. The reported species are assigned to recognized regional zoogeographical regions. Seventeen of the species are recorded for the first time for KSA, namely: Platypleura arabica Myers [Cicadidae, Hemiptera]; Cletomorpha sp.; Gonocerus juniperi Herrich-Schäffer [Coreidae, Hemiptera]; Coranus lateritius (Stål); Rhynocoris bipustulatus (Fieber) [Reduviidae, Hemiptera]; Cantacader iranicus Lis; Dictyla poecilla Drake &; Hill [Tingidae, Hemiptera]; Mantispa scabricollis McLachlan [Mantispidae, Neuroptera]; Cerocoma schreberi Fabricius [Meloidae, Coleoptera]; Platypus parallelus (Fabricius) [Curculionidae, Coleoptera]; Zodion cinereum (Fabricius) [Conopidae, Diptera]; Ulidia ?ru?ceps Becker [Ulidiidae, Diptera]; Atherigona reversura Villeneuve [Muscidae, Diptera]; Aplomya metallica (Wiedemann); Cylindromyia sp. [Tachinidae, Diptera]; Messor semirufus (André); and Nesomyrmex denticulatus (Mayr) [Formicidae, Hymenoptera]. Also, the reduviid bug Dasycnemus sahlbergi Bergroth, that was questionably recorded from KSA is confirmed herein as occurring in KSA. The generic name Peirates (Reduviidae, Hemiptera) and the specific name of Apis florea Fabricius (Apidae, Hymenoptera) were inadvertently misspelled in the original list and are corrected here. Zoogeographically, the present study supports the original study conclusion that the insect species composition of Al-Baha Province is strongly affiliated with the Afrotropical Region rather than to the Palearctic Region or the Eremic Zone. Our insect surveys emphasize the fact that parts of the Arabian Peninsula, including Al-Baha Province, ought to be considered part of the Afrotropical Region rather than in the Palaearctic Region or the Eremic Zone.     

Gastrointestinal helminth communities of two gekkonid lizard species,Nactus multicarinatus and Nactus pelagicus (Squamata: Gekkonidae), from the Republic of Vanuatu,Oceania

Gastrointestinal helminth communities of two gekkonid species, Nactus multicarinatus and Nactus pelagicus, from the Vanuatu Archipelago were examined. Both helminth communities were depauperate: N. multicarinatus harboured one species of Digenea, Mesocoelium monas, one species of Cestoda, Oochoristica javaensis, four species of Nematoda, Hedruris hanleyae, Parapharyngodon maplestoni, Physocephalus sp. (larvae in cysts), Filarioidea gen. sp. (juvenile); N. pelagicus harboured one species of Cestoda, O. javaensis, four species of Nematoda, H. hanleyae, Falcaustra tannaensis, P. maplestoni, Physocephalus sp. (larvae in cysts). In each helminth community P. maplestoni represented a core species and H. hanleyae was a secondary species. It is postulated that the helminth fauna infecting lizards of the Vanuatu Archipelago originated in Australia and Papua New Guinea and reached the archipelago by rafting; their establishment in Vanuatu was fortuitous.     

Revision of the southern African genus Frankenbergerius Balthasar with description of new taxa (Coleoptera: Scarabaeidae: Scarabaeinae)

The southern African genus Frankenbergerius Balthasar is revised. Two new species, F. opacus sp. n. and F. nitidus sp. n. (South Africa, Western Cape), and one new subspecies, F. armatus tuberculatus ssp. n. (South Africa, Mpumalanga), are described. F. imitativus (Péringuey) is considered a junior synonym of F. forcipatus (Harold). A key to the species and notes on biology are given.     

Hypersymbioses in the pinnotherid crabs (Decapoda: Brachyura: Pinnotheridae): a review

Members of the brachyuran family Pinnotheridae are nearly all symbionts of other invertebrates; some crabs are parasitic and others are commensal. Most live inside bivalve molluscs or in the tubes or burrows of polychaetes and other marine organisms. Animals living on or in pinnotherid crabs are considered to be hypersymbiotic and are reviewed here. Hypersymbionts are poorly represented within only 26 members (～8.6%) of the Pinnotheridae (20 species in the subfamily Pinnotherinae and six species in the Pinnothereliinae). Parasitic hypersymbionts are as follows: three species of fungi; one cestode larva (undescribed procercoid of Trypanorhynchida); one trematode metacercaria (undescribed Microphallidae); nematode cysts (undescribed); three species of Nemertea (Carcinonemertidae, two undescribed); two species of rhizocephalan Cirripedia (Sacculinidae; plus five or more undescribed potential sacculinid species); epicaridean Isopoda [13 species of Bopyridae (one undescribed) and four species of entoniscids (Entoniscidae, three undescribed)]. Preliminary biological information on undescribed entoniscids is presented. Several mainly incidental hypersymbioses involving ectosymbionts are known primarily from Pinnixa chaetopterana, a symbiont of polychaete burrows. The ctenostome bryozoan Triticella elongata is the only known obligate ectosymbiont in P. chaetopterana, but it also infests five other species of pinnotherids. Some of the other ectosymbionts (all incidental) on P. chaetopterana are stalked ciliates, hydroids, juvenile polychaetes, bivalve molluscs, balanomorph barnacles, harpacticoid copepods and urochordates. Species of ectosymbionts including an ectoproct bryozoan have been reported from other pinnotherid species. Factors influencing our meagre knowledge of hypersymbioses in the Pinnotheridae are discussed, among them the inaccessibility of crab hosts and research emphasis on taxonomy within the family.     

An identification guide to Eurysternine dung beetles (Coleoptera,Scarabaeidae)

Northeastern Atlantic and Mediterranean hermit crabs (Crustacea: Anomura: Paguroidea: Paguridae). I. The genus Pagurus Fabricius, 1775

A reappraisal of adult taxonomy of N.E. Atlantic and Mediterranean hermit crabs upholds the divisions A & B suggested for the species by MacDonal et al. (1957) from their studies of larval features. The nomenclature of three species is discussed. Pagurus variabilis (A. Milne Edwards and Bouvier, 1892) is relegated to the synonomy of P. alatus Fabricius, 1775 and P. excavatus (Herbst, 1791) is reinstated for Mediterranean and southern N. E. Atlantic material. A provisional check list is given of Paguroidean species occurring within the sea area 30°N–80°N:30°W–30°E and the Mediterranean Sea. An illustrated identification key is provided to the Pagurus species within these regions.

Hairworms found in Scottish agricultural land,with descriptions of two new species of Gordionus Muller (Nematomorpha: Gordiidae)

Three species of Nematomorpha were found in a survey of the ground beetles of Scottish agricultural land, Gordionus violaceus (Baird) and two undescribed new species, G. linourgos sp. nov. and G. diligens sp. nov. The morphology of all three species is studied with the aid of SEM, and the characteristics of the cuticle and the male terminal lobes described in detail. All species were found to be parasitic in ground beetles of the family Carabidae, in nine different species (Nebria brevicollis (Fabricius), Harpalus latus (Linnaeus), four species of Pterostichus, and three species of Calathus). Gordionus violaceus is also reported to be a parasite of the spider Arctosa alpigena (Lycosidae). Up to four specimens were found in the same host, typically one adult and several juvenile forms. Parasitized hosts had severe alterations of their reproductive, digestive and secretory systems. The three species of Gordionus were mostly found in grasslands and coniferous forest, most abundantly in June and July.     

Biodiversity of the scentless plant bugs (Hemiptera: Rhopalidae) in southern South America

This paper provides a comprehensive faunal survey of the Rhopalidae from southern South America with emphasis on the fauna of Argentina, based on published and unpublished data. The biodiversity from Argentina comprises 38 recorded species from six genera: Arhyssus Stål 1870 (one species), Liorhyssus Stål 1870 (two species), Niesthrea Spinola 1837 (five species), Xenogenus Berg 1883 (two species), Harmostes Burmeister 1835 (20 species), and Jadera Stål 1862 (eight species). We established accurate distributions for most of the species and report new distributional information for 27 of them. Most of these records are from Argentinean provinces, but we also report five new country records: three from Argentina – Harmostes (Harmostes) splendens Harris 1944, H. (Neoharmostes) bergi Göllner-Scheiding 1998 and Arhyssus tricostatus (Spinola 1852); one from Brazil – Xenogenus picturatum Berg 1883; and one from Paraguay – Harmostes (Harmostes) gravidator (Fabricius 1794).     

A revision of the genus Pandalus (Crustacea: Decapoda: Caridea: Pandalidae)

The genus Pandalus Leach, 1814, is revised based upon the abundant material from collections in various museums or institutions in the world. Altogether 20 species are recognized which appear to form five groups. Nineteen species are recognized in Pandalus, three of which are described as new: P. curvatus from southern Japan, and P. chani and P. formosanus from Taiwan. Four informal species groups are also recognized within the genus: P. montagui group (P. montagui Leach, 1814; P. borealis Krøyer, 1838; P. goniuruStimpson, 1860; P. jordani Rathbun, 1902; P. tridens Rathbun, 1902; and P. eous Makarov, 1935); P. stenolepis group (P. stenolepis Rathbun, 1902; P. curvatus sp. nov.); P. hypsinotus group (P. hypsinotus Brandt, 1851; P. danae Stimpson, 1857; P. prensor Stimpson, 1860; P. gracilis Stimpson, 1860; P. gurneyi Stimpson, 1871; P. nipponensis Yokoya, 1933; P. teraoi Kubo, 1937; P. chani sp. nov.; and P. formosanus sp. nov.); and P. platyceros group (P. platyceros Brandt, 1851; and P. latirostris Rathbun, 1902). The P. platyceros group appears to be most closely related to the genus Pandalopsis Bate, 1888, but Pandalus is retained as a possible paraphyletic group. Protandrous hermaphroditism is known in all but two species of the genus (P. curvatus and P. formosanus), for which only specimens of either male or female have been available. Pandalus propinqvus G. O. Sars, 1870, is transferred to a new monotypic genus Atlantopandalus, because of its lack of hermaphroditism and possession of some unique morphological characters, including one indicating a close relationsip to Dichelopandalus Caullery, 1896. All species are fully described and illustrated. The affinities and important morphological variations of the species are discussed. A key for adults is presented for the identification of the species. Biogeography of the genus is briefly discussed.     

The Mollissima subgroup of fannia Desvoidy,with the description of a new species from Burma and a revised key to species (Diptera: Muscidae)

Synopsis

A comparison of the type-species of the genus Coelomyia Haliday (C. mollissima Haliday) with that of the genus Fannia Desvoidy (F. scalaris Fabricius) shows that these two genera cannot be maintained as equivalent phylogenetie taxa. Coelomyia is synonymized with Fannia and its species placed in Fannia, four new combinations thus being established. The mollissima subgroup is defined and its affinities shown, a new species is described, and a revised key to species is given.     

Cirolanid isopod crustaceans from the Townsville region of Queensland,Australia, with descriptions of six new species

Summary

A wide variety of littoral and sublittoral marine habitats have been sampled in the vicinity of Townsville in N.E. Australia in order to assess the diversity of cirolanid isopods present.

Of the thirteen species represented in the collections six were previously undescribed. The species present were: Cirolana schioedtei Miers, 1884 (16m in mud/sand); C. pustulosa Hale, 1925 (mainly littoral habitats such as crevices in wooden installations); C. cranchii var. australiense Hale, 1925 (mainly littoral cryptic habitats); C. tumulosa sp. nov. (3–9 m in soft particulate substrata); C. arcicauda sp. nov. (3–10 m in soft particulate substrata); C. variguberna sp. nov. (2–18 m in soft particulate substrata); C. luticola sp. nov. (2–14 m in soft particulate substrata); Neocirolana bicrista sp. nov. (11 m in particulate substrata); Excirolana orientalis Dana, 1853 (littoral sand); Pseudolana concinna (Hale, 1925) (littoral sand); Pseudolana brevifimbria sp. nov. (littoral sand); Eurydice orientalis Hansen, 1890 (plankton and 5–11 m in soft particulate substrata); Eurydice inermis Hansen, 1890 (plankton and 2–11 m in soft particulate substrata).

The new species are described in detail and additional information is given on the other species—some of which have been poorly described in the past. In addition two closely related species, i.e. Cirolana tenuistylis Miers, 1884 and C. woodjonesi Hale, 1924 are also redescribed so as to avoid any confusion with the Townsville species.     

Flowers,faeces and cadavers: natural feeding and laying habits of flesh flies in Thailand (Diptera: Sarcophagidae,Sarcophaga spp.)

Baiting and flower watching mainly in forest habitats throughout Thailand (1997–2002) yielded 46 species of Sarcophaga Meigen. About 50% of the species are new to Thailand and several new to science. All 67 species of Sarcophaga so far reported from Thailand are listed and their taxonomic status and nomenclature updated. Emphasis on rearing (523 broods) ensured species identification through the male progeny of the otherwise mostly unidentifiable females, and allowed several new correct male–female associations, besides offering new insights into the flies' breeding strategies. Three natural larviposition habits were observed in the wild: (1) on faeces of carnivorous and omnivorous, but not herbivorous, mammals (coprobiodotic), e.g. S. africa (Wiedemann), S. albiceps Meigen, S. misera Walker; (2) on cadaver (necrobiodotic), e.g. S. krathonmai Pape and Bänziger, S. nathani (Lopes), S. saprianovae Pape and Bänziger; and (3) on both of them (amphibiodotic), e.g. S. dux Thompson, S. ruficornis (Fabricius). However, larvae of copro- and necrobiodotic species experimentally transferred to cadaver and faeces, respectively, also developed to normal adults. The unexpected laying choosiness between excrement or carrion in the wild is discussed, together with the role played by laying habits in deceptive pollination systems and myiases.     

Encarsia (Hymenoptera: Aphelinidae) parasitoids of Bemisia species in Taiwan (Hemiptera: Aleyrodidae)

The whitefly genus Bemisia (Hemiptera: Aleyrodidae) is represented by five species in Taiwan, including the notorious global pest Bemisia tabaci. A catalogue of Encarsia species attacking these whiteflies, based almost entirely on previously unpublished records, is provided. A key for the identification of the 17 Encarsia species known to parasitize Bemisia species in Taiwan is provided. Three new species, E. guangxingana Shih, Ko and Polaszek sp. nov., E. lineolata Shih, Ko and Polaszek sp. nov. and E. magnalata Shih, Ko and Polaszek sp. nov., are described from Taiwan. These new species were all reared from Bemisia giffardi.     

The saproxylic hoverflies (Diptera: Syrphidae) of Serbia

The revision of the saproxylic hoverflies collected in Serbia from 1950 to 2010 has revealed a total of 56 species, of which Sphiximorpha subsessilis (Illiger in Rossi) is new to the Balkan Peninsula and Arctophila superbiens (Muller), Blera fallax (Linnaeus), Brachyopa panzeri Goffe, Brachyopa testacea (Fallén), Brachyopa vittata Zetterstedt and Chalcosyrphus piger (Fabricius) are new to Serbia. According to “Syrph the Net, the database of European Syrphidae”, 16 of the 56 species are threatened with extinction in Europe, while 6 species are “strictly protected” and 13 are “protected” under Serbian legislation. Distribution maps for each species, as well as new data on adult habitats, are provided. The conservation status of the saproxylic hoverflies of Serbia is discussed. The present study attempts to provide a basis for the conservation of the saproxylic hoverflies of this Balkan country.
