A new species of the genus Palaeagapetus is described from Hokkaido, northern Japan, under the name of P. ovatus. Full descriptions of males, females, pupae, larvae and eggs are given. The extant species of this genus is recorded here for the first time from the Palaearctic Region. Larvae exclusively feed on leaves of a liverwort, Chiloscyphus polyanthos. Fifth (final) instar larvae make flattened long-oval cases of leaf pieces of the liverwort. Females copulate in several hours after emergence and deposit 50-85 eggs on leaves of the liverwort in two days. The eggs are not massed and hatch out in 21-23 days at 10.5-12.0℃.
