Material examined. 1♂ 1$, Chungcheongnam-do, Seocheon-gun, Seo-myeon, Sinhap-ri sand-dunes (N36°08 ʹ 47.6 ʺ, E126°32 ʹ 33.6 ʺ), 16 July 2020 (JC Sohn), [ GSN] SJC-1251 ($), GJUE ; 1♂, ditto, 20 August 2020 (JC Sohn), [ GSN] SJC-1252, GJUE ; 2$, Jeollanam-do, Sinan-gun, Is. Jaeundo, Jaeun-myeon, Gojang-ri , Oegi sand-dunes (N34° 53 ʹ 44.5 ʺ, E126°00 ʹ 27.4 ʺ), 16 July 2017 (JC Sohn), GJUE & NIBR .

Distribution. Korea (new record), Japan, China.

Host plants. Verbenaceae - Vitex trifolia subsp. litoralis Steenis ( Nasu et al., 2005) .

Remarks. The genus Noduliferola Kuznetzov, 1973 was established with the type species, N. abstrusa . The genus currently comprises nine species occurring in East and Southeast Asia, Australia and Micronesia ( Brown, 2005). It is introduced for the first time for the Korean fauna. Given the larval host plants, N. abstrusa can play role of a indicator species for coastal dunes.
