Abstract

A new species, Diamesa amanoi sp. n., from Mera La (alt. 5,050m), Nepal is described. The present new species is most closely related to D. subletti Makarchenko from North America. Diamesa plumicornis Tokunaga which had been regarded as Japanese endemic species is newly recorded from South Korea, and D. pankratovae Makarchenko et Bulgakov is recognized as a new synonym of D. filicauda Tokunaga.
