Abstract Collection data are given for 36 species of pamphiliid sawflies of the genera Acan-
tholyda, Cephalcia, Onycholyda and Pamphilius from Yamanashi Prefecture, central Honshu. Of
these, one species of Cephalciahas not been determined and two species of Onycholydaand four
species of Pamphilius are newly recorded from Yamanashi Prefecture. Compared with the other
well-investigated areas in Honshu, the pamphiliid fauna of Yamanashi Prefecture is very rich, hav-
ing the largest number of species in total (the same number as that of Tochigi Prefecture) and in
the “northern group” of species.
