HONSHU: Tochigi Pref. : 1 ♀, Nakagawa , Wami , 36°46'N 140°10'E , coll. larva on Rhododendron kaempferi var. kaempferi 9. VI. 2022 , mat. 14. VI ., em. 30. III. 2023 , S. Ibuki . Host plant . Ericaceae : Rhododendron molle (Blume) G.Don subsp. japonicum (A.Gray) K.Kron. ( Shinohara et al. , 2015 ), R. kaempferi Planch. var. kaempferi (new record). Remarks . The female specimen examined agrees with the holotype of E. takeuchii except that it has partly blackish trochanters and trochantelli. The lancet of this specimen ( Fig. 5 ) is almost identical with that of the holotype (fig. 19 in Prous et al. , 2011 ). Rhododendron molle subsp. japonicum was recorded as a host plant of this species in Hokkaido ( Shinohara et al. , 2015 ) and R. kaempferi Planch. var. kaempferi is newly recorded here as a host plant in Honshu. Empria takeuchii is likely to feed also on other Rhododendron species.
