Amongst the Tenthredinidae, the Nematinae show themselves to be as complicated as other insect groups which have been given the highest research priority within the well-funded Swedish Taxonomy Initiative (STI). Taxonomy and nomenclature of the group is in many ways chaotic. The fauna of Fennoscandia comprises more than 75% of the European Nematinae species. The project includes about 50 % of the Nematinae that are expected to occur in Sweden (i.e. all Nematinae with the exception of the subtribe Nematina). Of the approximately 300 European taxa that are to be considered, around 110 are already known from Sweden and 200 are already recorded from Fennoscandia.
Accordingly we expect not many less than 200 species in the group. An estimated 20 % of species or more probably require other names or may prove to be new to science. The few available comprehensive identification keys are from a modern viewpoint obsolete or lead to very inconclusive results. Only a handful of experts is currently capable of identifying a larger number of species, and often even these with much residual uncertainty.
A new classification and revision of this group is urgently required. In the course of the three year project, we intend to provide illustrated keys to the genera, species groups and species of Nematinae (excluding Nematina). To ensure a successful outcome, the work will involve numerous international collaborators.

ECatSym is the first online taxonomic catalogue that makes available comprehensive taxonomic data for the Symphyta. ECatSym covers about 6% of the megadiverse Hymenoptera. The catalogue meets the demands of the Global Biodiversity Information Facility (GBIF), in that taxonomic data are made freely available to everybody.
ECatSym offers the possibility of searching for the scientific and common names of species and genera, as well as their synonyms and misspelt names. The user is led to the valid name of the taxon that is sought and also can view associated images and literature references, together with information on distribution and higher classification. All data are based on the evaluation of about 9,000 publications (ca. 190,000 pages) on sawflies, mainly retro-digitalised and read with OCR, which can be made available, depending on copyright law, to other researchers. The high quality of information offered in ECatSym is reflected in the volume of data included. Currently, for example:
- 8.785 species and 831 genera,
- 30.855 name combinations,
- about 100.000 distributional data,
- about 200.000 links to literature.
ECatSym is continually updated as new publications appear. In the near future, data on host plants will be incorporated and made searchable. Furthermore, additional photos of type specimens will in future be included, as these become available as the result of work on various research collections. The static, printed version of the World Catalog of Symphyta (http://www.mapress.com/zootaxa/2010/1/zt02580p1064.pdf) appeared in 2010 in Zootaxa. A catalogue of family group names is currently being compiled.
