Two new species, Ooencyrtus alrake Hayat, sp. nov. and Syrphophagus wayanadensis Hayat, sp. nov. (Hymenoptera: Chalcidoidea: Encyrtidae), are described from material collected in Kerala State (India) from Trioza jambolanae Crawford (Hemiptera: Psylloidea: Triozidae), a leaf gall-inducer on species of Syzygium (Myrtaceae). Two species, Psyllaephagus garuga S. Singh and P. phacopteron S. Singh, b...

The 14 species of Ficus of the subgenus Sycomorus (Moraceae) are invariably pollinated by Ceratosolen species (Hym. Chalcidoidea), which in turn reproduce in the fig florets. They are distributed mostly in continental Africa, Madagascar, and the Mascarene and Comoro Islands, but 1 species extends its geographical range all over the Oriental region. Fig-pollinator relationships are usually stric...

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...
