Based on field observations and rearings in 2010 to 2011 in Mureung valley, Gangwon-do, Korea, host plants are newly recorded for two pamphiliid sawflies belonging to the genus Onycholyda. Agrimonia pilosa(Rosaceae) is the host of Onycholyda nigroclypeata SHINOHARA, 1987, and Rubus parvifolius L. (Rosaceae) is the host of Onycholyda odaesana SHINOHARA and BYUN, 1993. The host and larva of 0. nigroclypeata have been unknown. Brief descriptions of the larvae and notes on the life history of the two species are given
