@article {1930, title = {Revision of the endemic New Zealand braconid wasp genus Metaspathius: new subfamily placement, and descriptions of four new species including three with fully winged females (Hymenoptera: Braconidae: Mesostoinae)}, year = {2019}, abstract = {

The endemic New Zealand cyclostome braconid wasp genus Metaspathius\ Brues, which was previously only known from a single specimen, an\ apterous female, is revised. Four new species, including three with fully\ winged females, are described and illustrated: Metaspathius chathamicus\ Ward, sp. nov.; M. hemipterus Belokobylskij, sp. nov.; M. kuscheli Ward \&\ Belokobylskij, sp. nov.; and M. sharkeyi Quicke \& Butcher, sp. nov.\ Metaspathius apterus Brues is illustrated. The first host record for the\ genus is provided: Metaspathius kuscheli sp. nov. is recorded as a larval\ parasitoid of the New Zealand endemic weevil Phrynixus astutus Pascoe,\ 1876 (Curculionidae). DNA sequence data (CO1 and 28S) for two of the\ species are included in an analysis of a broad range of cyclostome\ Braconidae with emphasis on basal taxa. The results show that\ Metaspathius belongs to a clade restricted to New Zealand within the\ heterogeneous basal subfamily Mesostoinae van Achterberg, 1975. A\ revised morphological diagnosis of the Mesostoinae is presented in the\ light of the discovery that Metaspathius is a member. The relationships\ of the Maxfischeriinae are discussed in the light of molecular findings.
