Twelve species of Dibrachys Förster are studied from China, of which four new species, Dibrachys golmudica Jiao & Xiao, sp. n., Dibrachys kunmingica Jiao & Xiao, sp. n., Dibrachys liaoi Jiao & Xiao, sp. n. and Dibrachys qinghaiensis Jiao & Xiao, sp. n., and four newly recorded species, Dibrachys braconidis (Ferrière & Faure), Dibrachys confusus (Girault), Dibrachys hians Bouček and Dibrachys ma...

Taxonomists are people who describe species. This work is essential for the conservation of biodiversity and for estimating how many species there are left to be discovered, the so-called missing species [1]. However, it has been claimed the science of taxonomy is in crisis [2] because researchers are afraid that the number of people describing new species is in decline [3,4]. In a recent lette...

The parasitoid wasp genus Nasonia (Hymenoptera: Chalcidoidea) is a well-established model organism for insect development, evolutionary genetics, speciation, and symbiosis. The host-microbiota assemblage which constitutes the Nasonia holobiont (a host together with all of its associated microbes) consists of viruses, two heritable bacterial symbionts and a bacterial community dominated in abund...

A new sCecies of Tanaost~gmodes (Hymenoptera Chaicidoidea Tariaostigmal~dae) is described from China-Tanaoshgmodes pueranae sp nov This is the first record of this fam~ly In China This new species has potent~al as a brological control agent for control of kudzu, Puerana lobate in the U S because its preference for making leaf galls on kudzu It was determined that the wasp has two generations pe...

Among the Chalcidoids, hymenopteran parasitic wasps that have diversified lifestyles, a partial mitochondrial genome has been reported only from Nasonia. This genome had many unusual features, especially a dramatic reorganization and a high rate of evolution. Comparisons based on more mitochondrial genomic data from the same superfamily were required to reveal weather these unusual features are...

Ficus microcarpa is an Asian fig tree that is ornamentally cultivated. The specific pollinator, Eupristina verticillata Waterston, and the non-pollinators Walkerella microcarpae Boucek and Philotrypesis emeryi Grandi, have been reported associated to F. microcarpa in Brazil. In here we report for the first time the occurrence of Odontofroggatia ishii Wiebes and Philotrypesis taiwanensis Chen et...

in order to identify parasitoids of poplar aphid, sampling was done at urban areas of tehran in 2011. aphid galls were put in clear plastic containers and were evaluated until emergence of parasitoids on daily basis. among the samples, a new species namely protaphelinus nikolskajae (yasnosh, 1963) (chalcidoidea: aphelinidae) was identified. this species is a parasitoid of the popular aphid, pem...
