The species within this catalogue follow the taxonomy of the 2014 checklist by Liston et al. An account for each species will be added in due course. The species descriptions are not meant to act as a main means of identification but will hopefully add confidence to any keyed out identification. The taxonomy of sawflies is subject to much debate and change is likely as DNA analysis unravels some of the complexity. The taxonomy of the nematines in particular is likely to change dignificantly in the coming years but for the time being largely follows Benson.
