Bivalve-infesting immature pycnogonida Nymphonella tapetis was discovered in a new host, Hiatella orientalis, from the Pacific coast of northern Japan. The parasitic rate was only 1. 1 percent and the assumption of host size selection by pycnogonid at infestation was rejected on the basis of the data obtained on infested host size. This species shows isometrical growth and its infesting season is early spring. In the previous reports, immature specimens of the same species were found in three infaunal bivalves, Ruditapes philippinarum, Protothaca jedoensis, and Theora fragilis. The discovery of the new host, Hiatella orientalis which has an epifaunal mode of life, suggests the existence of other potential host bivalves for Nymphonella tapetis.
