The Chalcidoidea bush of life: evolutionary history of a massive radiation of minute wasps.

Chalcidoidea are mostly parasitoid wasps that include as many as 500 000 estimated species. Capturing phylogenetic signal from such a massive radiation can be daunting. Chalcidoidea is an excellent example of a hyperdiverse group that has remained recalcitrant to phylogenetic resolution.

Ooencyrtus pitosina (Hymenoptera: Encyrtidae)-A natural enemy of Samoan swallowtail butterfly Papilio godeffroyi (Lepidoptera: Papilionidae).

A new species of encyrtid wasp, Ooencyrtus pitosina Polaszek, Noyes & Fusu sp. n., (Hymenoptera: Encyrtidae: Encyrtinae) is described as a gregarious parasitoid in the eggs of the endemic Samoan swallowtail butterfly Papilio godeffroyi (Lepidoptera: Papilionidae) in the Samoan archipelago.

Leptoomidae, a new family of Eocene fossil Chalcidoidea (Hymenoptera), and family classification of Eocene fossil genera originally described in Neanastatinae (Eupelmidae).

Leptoomidae Gibson fam. nov. (Chalcidoidea) is described for the Eocene Baltic amber fossil genera Leptoomus Gibson, type genus, reassigned from Tanaostigmatidae, and Neanaperiallus Gibson, reassigned from Neanastatinae (Chalcidoidea: Eupelmidae) sensu Gibson (2009).

Revision of the World Species of Timberlake (Hymenoptera: Trichogrammatidae).

species are important models for basic organismal research, and many are potential biological control agents. We present the first extensive revision of species of the genus based on morphological and molecular data. Our revision includes all previously described species, 6 of which are synonymized, and 22 of which are described here as new.

Goniozus omanensis (Hymenoptera: Bethylidae) an important parasitoid of the lesser date moth Batrachedra amydraula Meyrick (Lepidoptera: Batrachedridae) in Oman.

A new species of bethylid parasitoid wasp, Goniozus omanensis Polaszek sp. n., is described based on morphology and DNA sequence data.
