 Material examined. [Korea] 1♂, Jeollanam Prov., Wando-gun, Is. Bogildo, Bogil-myeon, Buhwang-ri (34°07 ʹ 39.7 ʺ N 126°31 ʹ 13.3 ʺ E), 31 August 2017, leg. J.-C. Sohn, genitalia slide no. SJC-1308, GJUE; 1$, Jeollanam Prov., Wando-gun, Is. Wando, Wando-eup, Jeongdo-ri (34°17 ʹ 53.1 ʺ N 126°42 ʹ 46.8 ʺ E), 24 August 2017, leg. J.-C. Sohn, genitalia slide no. SJC-1326, NIBR. [Japan] 2♂, 2$, Honshu, Aichi Pref., Mt. Sanage-yama, 15 May 1980 (larvae collected on Quercus glauca), 29-31 May and 9 June 1980 (adults emerged), genitalia slide no. SJC-1313 ($), 1205 (♂), NMNS.   
 Distribution. Korea (new record), Japan.   
 Host plants. Fagaceae - Castanea crenata Siebold & Zucc., Lithocarpus edulis (Makino) Nakai, Quercus acuta Thunb., Q. acutissima Carruth., Q. gilva Blume, Q. glauca Thunb., Q. myrsinifolia Blume, Q. phillyreoides A. Gray (Arita, 1987; 2013).   
 Remarks. Adults of this species exhibit display behavior in the similar way to Brenthia spp., described in Aiello and Becker (2004). It is known that such behavior is involved in jumping spider mimicry (Rota and Wagner, 2006).
