My research interest is taxonomy of parasitoid wasps (Hymenoptera) especially family ichneumonidae.  The diversity of these wasps are still poorly understanding in Japan and also Asia. Compared to Europe and North America, Asian parasitoid wasps have many taxonomic problems, even in the common species. The existence of many undescribed species and the lack of distribution records hinder the promotion of various studies, e.g., biology, zoogeography and applied entomology. Thus I think that  even α-taxonomy of them are still needed now. In addition, like as Europe, North America, Russia and China, identification system (e.g., books, database and reference specimen collection of museum) for non-taxonomist users written by the mother language is very important. Unfortunately, in Japan, almost no identification system by Japanese language had been published.

       By this background, I try to classify various taxa of parasitoid wasps and to make some identification guides for Japanese species of them.


New taxa described by K. Watanabe.
