Abstract

Two cirolanid isopods, Eurydice longiantennata Nunomura and Ikehara, 1985 and Metacirolana japonica (Hansen, 1890), are newly reported based on the materials collected from the subtidal zone around Jeju Island. Eurydice longiantennata can be distinguishable from its congeners by the following features: body length is 5 mm; antennule is not extending beyond the cephalon; flagellum of the antenna is consisted of 31 flagellar articles; and pleotelson has eleven teeth and twelve setae distally. Metacirolana japonica is distinguished from its related species by the following characteristics: body is not ornament; pleonite 1 is entirely visible dorsally in male; pleotelson is gradually tapering distally; and uropodal rami have serrate margins.
