Taxonomic Review of the Genus Anterhynchium Saussure (Eumeninae, Vespidae, Hymenoptera) from East Asia

ABSTRACT Taxonomic study of the genus Anterhynchium from the Eastern Asia is carried out. A total of 15 forms included in four species were reviewed: A. melanopterum, A. flavopunctatum flavopunctatum, A. flavopuntatum opulentum, A. yunnanensis, A. flavomarginatum flavomarginatum, A. f. koreanum, A. f. tsushimarum, A. f. umenoi, A. f. micado, A. f. procella, A. f. insulicola, A. f. sulphreum, A. f. amamense, A. f. hanedai and A. f. formosicola. However, the A. flavopunctatum opulentum and A. yunnanensis are only cited for future work, due to the lack of available materials. Key to the other species and subspecies are revised, and photos showing diagnostic characters and coloration are presented. The male genitalic characters for accurate identification were separately discussed.     

Taxonomic Review on the Far Eastern Species of the Genus Discoelius Latreille (Hymenoptera: Eumeninae, Vespidae)

Far eastern species of the genus Discoelius Latreille are taxonomically reviewed. Two species are confirmed: Discoelius zonalis (Panzer) and D. dufourii Lepeletier. Discoelius japonicus originally described from Japan is synonymized under D. zonalis. Discoelius dufourii is newly recorded in Manchuria and Korea. The taxonomic status of D. manchurianus is briefly discussed.     

Biogeographic characteristics of Far Eastern wasps: A case study with eumenine wasps (Hymenoptera: Vespidae: Eumeninae)

A total of 107 forms of 88 eumenine wasp species occurring in the Far East were used to produce a more comprehensive picture of the geographical pattern of wasps in the Far East. All forms occurring in the Far East were biogeographically classified into 22 types in four larger categories, and a summarized table and discussion are presented. The eumenine wasp fauna of the Far East was characterized as a mixture of a fair number of endemic elements, a moderate number of transpalearctic elements, and some Oriental elements. The endemism of the Far East reached 0.71 at the species/subspecies level when the calculation was based on true Palearctic elements occurring in Far Eastern Russia, the Korean peninsula and Japan proper. The relationship between the Far Eastern fauna and the Central/Western Palearctic faunas was also analyzed and discussed. The species occurring in each treated district was counted, and provides evidence for the importance of the Korean fauna in biodiversity evaluation/estimation of Far Eastern fauna. The similarity index between the Korean Peninsula and Japan proper, the Korean Peninsula and the Russian Far East, and the Russian Far East and Japan proper was calculated to explain possible factors for faunal formation in the Far East. The distributional pattern of each form treated in this study and its relatives is tabulated in Appendix I.     

Microsatellite markers for the wasp Euodynerus foraminatus (Vespidae: Eumeninae)

We have identified five polymorphic microsatellite loci for the solitary wasp Euodynerus foraminatus, using a partial genomic library constructed from random amplified polymorphic DNA fragments. We detected between three and 13 alleles per locus in a sample of 30 female wasps collected in southwest Michigan, USA. Observed heterozygosities ranged from 0.2 to 0.73. These markers will be used in our ongoing studies of sex determination and naturally occurring inbreeding in this species.     

Genetic diversity of genus Vespa including an invaded species of V. velutina (Hymenoptera: Vespidae) in Korea inferred from DNA barcoding data

With about 5000 known species, the Vespidae is a large family belongs to order Hymenoptera. The genus Vespa with 22 species is one of the four genera of the subfamily Vespinae. In Korea, 10 species and subspecies are recognized. Because of their social behavior, their treat to human health and their impact in apiculture, the reliable and sometimes automated identification of these insects to species level are important. To test the efficacy of DNA barcoding method for identification of species of the genus Vespa in Korea, 30 samples of eight Korean species of genus Vespa were collected and mitochondrial DNAs of 658 bp fragment cytochrome oxidase subunit 1 (CO1) region were sequenced. A Bayesian Inference based on COI gene of the Korean Vespa species was constructed. The phylogenetic tree shoed that identification of all specimens is possible based on COI gene and we found strong relation between the sequences of the collected species from different localities in South Korea which clustered together with 100% support with sequences of the same species in GenBank. The results demonstrate that DNA barcoding is a useful technique for rapid and accurate species recognition in Korean Vespa species. The DNA barcode part of COI for V. binghami is provided for the first time that can help for identification of this species through DNA barcoding. Also, the genetic diversity among Korean Vespa velutina was zero suggests that the invasion might have occurred in a single event with small number of founders.

These two new species are Ectopioglossa trimacula sp. nov. and E. convexa sp. nov., collected from Guangxi and Yunnan, China, respectively. Among other three nomial species, E. sublaevis (Smith, 1857) is new to China. An updated key to the Oriental species is also provided.     

Isolation and characterization of microsatellite markers in the solitary hunting wasp Ancistrocerus adiabatus (Vespidae: Eumeninae) and their cross utility in other species of Ancistrocerus

We have developed seven microsatellite primers for the solitary wasp Ancistrocerus adiabatus. The number of alleles per locus ranged from three to 14. The markers were developed to study population structure, inbreeding and sex determination of A. adiabatus. For each locus, we genotyped 30 female wasps collected from Southwest Michigan. The observed heterozygosity ranges from 0.067 to 0.933. We have also determined that primers for these microsatellite loci amplify in three other species in the genus: Ancistrocerus antilope, Ancistrocerus catskill, and Ancistrocerus campesterus.

Polymorphic microsatellite loci for eusocial wasps (Hymenoptera: Vespidae)

Hymenopterans are an important model for studying the evolution of cooperation in animal societies. Here, we characterize 19 microsatellite loci, isolated from the common wasp Vespula vulgaris, that can be used to study genetic variation in three genera (seven species) within the Vespidae. The number of alleles in V. vulgaris was moderate, varying from 2 to 14, with expected heterozygosity ranging between 0.04 and 0.93. Eleven loci amplified DNA in V. austriaca and Dolichovespula sylvestris, nine in V. germanica, eight in Vespa crabro and V. rufa, seven in D. media and only five loci could be used for D. norwegica.

西藏波密柑马蜂的筑巢习性（英文）

柑马蜂Polistes mandarinus在不同的环境中会利用植物材料制作各种不同的蜂巢。我们在2009年5-8月间观察研究了西藏自治区波密县的柑马蜂筑巢习性, 并收集62个蜂巢。柑马蜂利用植物纤维和树脂将它们的巢穴筑于当地居民的木屋檐下。收集的42个在用蜂巢中, 8月末平均拥有79.64±65.28个蜂房, 13.1±10.68个蜂蛹。20个弃用蜂巢中, 平均拥有12.95±3.99个蜂房。8月末, 成功的柑马蜂群拥有约80个个体。研究地的柑马蜂采取3种方式来筑巢, 但以第1种方式最为普遍。第1种筑巢方式筑造的蜂巢以两个蜂房连接巢柄, 结构最为稳定, 所以也应用最广, 后两种筑巢方式筑造的蜂巢均以一个蜂房连接巢柄, 是由于越冬雌蜂在找不到合适的筑巢材料时才采取的建巢方式。     

The origin and evolution of social life in the Stenogastrinae (Hymenoptera,Vespidae)

The Stenogastrinae are a subfamily of the Vespidae. The main difference between these and other social wasps (Polistinae and Vespinae) is a jelly-like substance that the Stenogastrinae secrete from the Dufour 's gland and use in many functions of their biology. It is suggested that this substance greatly contributed to the evolution of social life in these wasps by making it possible to nourish the brood with liquid food and store it in the nest, thus favoring also the evolution of the behavioral mechanisms which facilitated interactions between adults. Social organization of the colonies may have been kept at a low level through a basic system of continuous temporary helper replacement, while the evolution of large colonies was restrained, as well as by the poor quality of construction material, low egg-laying capacity and limited production of abdominal substance, imperfect social regulatory mechanisms, and the absence of defensive mechanisms of the colonies against large predators.     

Diversity of wasps (Hymenoptera: Aculeata: Vespidae) along an altitudinal gradient of Atlantic Forest in Itatiaia National Park,Brazil

Surveying the diversity of stinging wasps (Hymenoptera: Aculeata) provides an important information base to assist in biodiversity conservation and the management of forest reserves, as wasps depend on and maintain the population balance of several other groups of insects. In accordance, this paper presents an altitudinal survey of wasps (Hymenoptera, Aculeata, Vespidae) in Itatiaia National Park, Brazil, which is a protected area covered by Atlantic Forest in a mountainous landscape, with altitudes ranging between 540 and 2791 metres above sea level. Six altitudinal zones were sampled with entomological net, and the abundance and diversity of the species were indicated by zones. Field sampling took 288 h of discontinuous activity, which was randomly conducted from December 2012 to December 2013. A total of 398 individuals belonging to 29 species and two subfamilies (Eumeninae and Polistinae) were sampled. Eight species are new records for the state of Rio de Janeiro. We found a monotonic decrease in wasp diversity in relation to altitude, and the number of captured individuals differed significantly between the low and high altitudes.
