Diversity of digger wasps in Kasnak Oak Forest Nature Reserve,Isparta, Turkey,with records of eight species new to Turkey (Hymenoptera: Sphecidae,Crabronidae and Ampulicidae)

Three stations selected for altitude and habitat types within the Kasnak Oak Forest Nature Reserve (Isparta, Turkey) were studied comparatively for species composition, richness and abundance of the Hymenoptera families Ampulicidae, Crabronidae, and Sphecidae. A total of 56 species was recorded, 1 from the family Ampulicidae, 43 from the family Crabronidae and 12 from the family Sphecidae. 8 species are new records for Turkey.     

DNA barcodes identify 99 per cent of apoid wasp species (Hymenoptera: Ampulicidae,Crabronidae, Sphecidae) from the Western Palearctic

The apoid wasps have traditionally been regarded as a paraphyletic assemblage of four families (Ampulicidae, Crabronidae, Heterogynaidae and Sphecidae) that are closely related to the bees (Anthophila). The present study covers the three families of apoid wasps known to occur in Europe, that is, the Ampulicidae, Crabronidae and Sphecidae. DNA barcode sequences of 3,695 specimens of apoid wasps were analysed for the present study, including 21 specimens of Ampulicidae, 3,398 Crabronidae and 276 Sphecidae. The sequences of the dataset represent 661 species of apoid wasps, including two species of Ampulicidae, 613 of Crabronidae and 46 species of Sphecidae. The dataset includes DNA barcodes of 240 species of German apoid wasps, representing 88% of the German fauna, and 578 European species, representing 65% of the European apoid wasp fauna. The study demonstrates that virtually all species of the three examined families can be reliably identified by DNA barcodes. The implications of highly congruent results between traditional taxonomy and DNA barcoding for the reliable application of DNA‐based identifications are discussed.     

Alpha–beta diversity in trap-nesting wasps (Hymenoptera: Aculeata) in Southern Brazil

This study was carried out at the Parque Municipal das Araucárias, in the municipality of Guarapuava, state of Paraná, southern Brazil. The aims of the present study were to access the spectrum of wasp species inhabiting trap-nests in three habitats, to record their richness and diversity and elucidate the process responsible for their composition and abundance and to investigate if there is difference in their diversity between Brazilian tropical and subtropical regions. A total of 1097 nests, belonging to 21 species of solitary wasps, were collected. Of these, nine belonged to the family Vespidae (42.86%), six to Pompilidae (28.57%), four to Crabronidae (19.05%) and two to Sphecidae (9.52%). Crabronidae was the most abundant family in the samplings, with a total of 927 collected nests (84.3%). The environment that presented the greatest species diversity, richness and evenness was the grassland areas. Using the Bray–Curtis coefficient (beta diversity), the greatest similarity, in relation to species abundance, occurred between swamp and grasslands. In contrast, the araucaria forest was the habitat with the greatest dissimilarity, a result corroborated by the correspondence analysis.     

Artificial covering on trap nests improves the colonization of trap-nesting wasps

To evaluate the role that a trap‐nest cover might have on sampling methodologies, the abundance of each species of trap‐nesting Hymenoptera and the parasitism rate in a Canadian forest were compared between artificially covered and uncovered traps. Of trap tubes exposed at eight forest sites in six trap‐nest boxes, 531 trap tubes were occupied and 1216 individuals of 12 wasp species of four predatory families, Vespidae (Eumeninae), Crabronidae, Sphecidae and Pompilidae emerged over 2 years, and no bee species were found. Results indicated that artificial covering led to a significant increase in the number of nested tubes of Ancistrocerus adiabatus, Ancistrocerus antilope, Ancistrocerus campestris and Auplopus mellipes, and significant effects of covering were not found for the other species. No significant difference in the overall parasitism rate between covered and uncovered traps was noted. These suggested that the covering technique could provide more opportunities for some wasp species to colonize trap nests.     

Identifying the sister group to the bees: a molecular phylogeny of Aculeata with an emphasis on the superfamily Apoidea

Debevec, AH., Cardinal, S & Danforth, BN. Identifying the sister group to the bees: a molecular phylogeny of Aculeata with an emphasis on the superfamily Apoidea. —Zoologica Scripta, 41, 527–535. The hymenopteran superfamily Apoidea includes the bees (Anthophila) as well as four predatory wasp families (Heterogynaidae, Ampulicidae, Sphecidae and Crabronidae) collectively referred to as the “sphecoid” or “apoid” wasps. The most widely cited studies suggest that bees are sister to the wasp family Crabronidae, but alternative hypotheses have been proposed based on both morphological and molecular data. We combined DNA sequence data from previously published studies and newly generated data for four nuclear genes (28S, long‐wavelength rhodopsin, elongation factor‐1α and wingless) to identify the likely sister group to the bees. Analysis of our four‐gene data set by maximum likelihood and Bayesian methods indicates that bees most likely arise from within a paraphyletic Crabronidae. Possible sister groups to the bees include Philanthinae, Pemphredoninae or Philanthinae + Pemphredoninae. We used Bayesian methods to explore the robustness of our results. Bayes Factor tests strongly rejected the hypotheses of crabronid monophyly as well as placement of Heterogynaidae within Crabronidae. Our results were also stable to alternative rootings of the bees. These findings provide additional support for the hypothesis that bees arise from within Crabronidae, rather than being sister to Crabronidae, thus altering our understanding of bee ancestry and evolutionary history.

Jumping plant lice (Homoptera: Psylloidea) of the temperate neotropical region. Part 1: Psyllidae (subfamilies Aphalarinae, Rhinocolinae and Aphalaroidinae)

The psyllid-fauna of temperate and subantarctic South America comprises members of three families: Calophyidae, Triozidae and Psyllidae. Three subfamilies of the Psyllidae are revised in this paper: the Aphalarinae are represented by two species in two genera, one of which develops on Aquifoliaceae; the Rhinocolinae are represented by two congeneric species on Anacardiaceae while the Aphalaroidinae contain 38 species in seven genera trophically linked to the Compositae, Euphorbiaceae, Leguminosae, Myzodendraceae, Rhamnaceae, Solanaceae and Zygophyllaceae. The family Psyllidae (= Aphalaridae syn. nov. , =Spondyliaspididae syn. nov. ) and the constituent subfamily Aphalaroidinae (= Arepuninae syn nov. , = Ciriacreminae auct. pp) are redefined. Three genera and 30 species are described as new and two new generic, two new specific synonyms, and five new combinations are proposed. Information on larvae and host plant relationships is also given. Lectotypes are designated for eight species and a type-species is fixed for one genus. Keys are provided for the identification to species.

为了丰富西藏高原植物区系地理研究资料,深入开展该区域植被生态学研究、生物资源开发利用与保护,该研究通过野外调查、标本采集以及查阅相关的文献资料,对西藏佩枯错种子植物区系进行了统计分析。结果表明:(1)植物种类较贫乏。佩枯错共有种子植物31科77属115种,仅占西藏种子植物的18.90%、6.73%、2.17%。其中裸子植物2科2属2种,被子植物29科75属113种;被子植物中双子叶植物有23科58属91种,单子叶植物6科17属22种。(2)优势科明显,单种科占绝对优势。所有科中有5个科至少含有7种种子植物,占该研究区总种数的39.13%,是该区系的主要组分;同时科数中有11科仅含1种植物,该类科占一定优势。(3)种子植物的区系成分较复杂,划分为3个科分布区类型和10个属分布区类型,其中温带成分占绝对优势:温带分布科、属分别占总数的29.03%和77.92%,表明本区系具有明显温带性质。(4)科属特有现象不明显,没有中国特有科分布,仅有1个中国特有属分布,说明佩枯错植物区系的特有化程度极低,表现出寒旱化与高山、高原特化综合而成的高寒植物区系的年轻性。     

Hymenoptera aculeata of raised bogs in Belarus

The long-term studies (1986–2003) of raised bogs of Belarus revealed 167 species of aculeates belonging to 7 families: Sapygidae (1), Chrysididae (11), Pompilidae (19), Eumenidae (19), Vespidae (9), Sphecidae (76), and Apidae (32). The dominant species (not counting ants) are Vespula rufa (16.6%), Bombus jonellus (11.3%), B. lucorum (7.5%), Anoplius nigerrimus (5.1%), B. pascuorum (3.9%), Passaloecus turionum (3.8%), Argogorytes mystaceus (3.2%), Dipogon bifasciatus (3.1%), Pemphredon lugens (3.0%), and Trypoxylon attenuatum (2.6%). Approximately two-thirds of the species found in raised bogs nest in the upper layer. The spatial distribution of aculeates depends primarily on the distance from the bog margins and the presence of contrasting areas, such as lake banks or glades. The highest activity of various aculeate families (except for Vespidae) was observed in June. The total abundance of aculeates was found to be correlated with solar activity, the strongest correlation being observed in Vespidae. The abundance of different wasp families varied noticeably from year to year, depending on climatic parameters.     

Analysis of family-level relationships in bees (Hymenoptera: Apiformes) using 28S and two previously unexplored nuclear genes: CAD and RNA polymerase II

We analyzed a combined data set of two protein-coding nuclear genes (CAD and RNA polymerase II) and a nuclear ribosomal gene (28S D2-D4 region) for 68 bee species and 11 wasp outgroups. Our taxon sampling included all seven extant bee families, 17 of 20 subfamilies, and diverse tribes. Wasp outgroups included the two families most closely related to bees: Crabronidae and Sphecidae. We analyzed the combined and single gene data sets using parsimony and Bayesian methods, which yielded largely congruent results. Our results provide reasonably strong support for family and subfamily-level relationships among bees. Our data set strongly supports the sister-group relationship of the Colletidae and Stenotritidae, and places Halictidae as sister to this clade combined. Our analyses place the Melittidae and the long-tongued (LT) bee clade (Apidae+Megachilidae) near the base of the tree with Colletidae (and Stenotritidae) in a fairly highly derived position. This topology ("Melittidae-LT basal") was obtained in previous morphological studies under certain methods of character coding. A more widely accepted tree topology that places Colletidae (and/or Stenotritidae) as sister to all other bees ("Colletidae basal") is not supported by our data. The "Melittidae-LT basal" hypothesis may better explain patterns in the bee fossil record as well as historical biogeography of certain bee groups. Our results provide new insights into higher-level bee phylogeny and indicate that CAD, RNA polymerase II, and 28S are useful data sets for resolving Cretaceous-age divergences in bees and other Hymenoptera.

Expression of odorant-binding proteins and chemosensory proteins in some Hymenoptera

The expression of chemosensory proteins (CSPs) and odorant-binding proteins (OBPs) in individuals of different castes and ages have been monitored in three species of social hymenopterans, Polistes dominulus (Hymenoptera, Vespidae), Vespa crabro (Hymenoptera, Vespidae) and Apis mellifera (Hymenoptera, Apidae), using PCR with specific primers and polyclonal antibodies. In the paper wasp P. dominulus, OBP is equally expressed in antennae, wings and legs of all castes and ages, while CSP is often specifically present in antennae and in some cases also in legs. In the vespine species V. crabro CSP is antennal specific, while OBP is also expressed in legs and wings. The three CSPs and the five OBPs of A. mellifera show a complex pattern of expression, where both classes of proteins include members specifically expressed in antennae and others present in other parts of the body. These data indicate that at least in some hymenopteran species CSPs are specifically expressed in antennae and could perform roles in chemosensory perception so far assigned only to OBPs.

Taxonomic composition and zoogeographic characteristics of the flea fauna (Siphonaptera) of Russia

255 species and 59 subspecies of fleas from 55 genera of 7 families are known from Russia, which is 30% of the Palaearctic fauna. Additionally, over 187 species of 47 genera from 7 families are known from the neighboring territories of Central and Southern Europe, Transcaucasia, Kazakhstan, Middle Asia, Mongolia, Northeast China, and Japan. 13 species of 12 genera are known only from Russia. Noteworthy is the low percent of endemic species (not more than 4%) and genera (one genus) in the Russian fauna. The principal centers of taxonomic diversity in the Palaearctic, including many endemic species and genera, lie in the Eastern Asian, Central Asian, and Turano-Iranian Subregions, outside Russia and the Euro-Siberian Subregion. The bulk of the Russian fauna is formed by the species and genera of the three largest flea families: Hystrichopsyllidae, Ceratophyllidae, and Leptopsyllidae. The family Ceratophyllidae has the greatest number of genera in the Russian fauna, and Hystrichopsyllidae, the greatest number of species. Western (Western and Western-Central Palaearctic; 84 species from 41 genera of 7 families) and Eastern (Central-Eastern and Eastern Palaearctic; 78 species from 42 genera of 6 families) species are nearly equally represented in the Russian fauna.
