Guide to the sawflies and woodwasps (Hymenoptera, Symphyta) of New Zealand.

Abstract

Thirteen species of sawflies and woodwasps of Symphyta (Hymenoptera) are known from New Zealand. Four species are endemic to New Zealand, eight species have been accidentally introduced, and one species has been deliberately released as a biological control agent. We provide a guide to the identification of these species, with keys to both adult and larval life stages, and for each species provide information on synonymy, diagnosis, description of known sexes of adults and of larvae, taxonomic notes, hosts, biology, and distribution.
