Subgenital plate with 1 long macroseta near base and several short microsetae near apical margin, short rigid microsetae along apical margin; apical margin with one small well-sclerotized preapical projection (Fig. 10). Style curved inner side and apex bent down and inner margin with row of microsetae (Fig. 9). Aedeagus in caudal view antler shapes with paired preapical and apical processes; apical processes simple, unbranched, extended dorsolaterad; preapical processes extended dorsolaterad, each with 3 processes; aedeagal shaft strongly recurved in lateral view and G shaped, all processes extended slightly anterad (Figs 5, 6). Connective Yshaped, arms slender and sinuate (Fig. 8). Measurements. Body length: males 3.5 ~ 3.8mm, females 3.5mm Type materials. Holotype: [CNU] ♂, Korea, Gongju-si, Banpo-myeon, Dongwol valley, 0 1. ix. 2014, coll. S. Oh.; Paratypes: [CNU] 56 ♂♂, 1 ♀ same data as holotype.; [CNU] 2 ♂♂, Korea, Geumsan-gun, Jinsan-myeon, Mt. Daedun, 29. vii. 2014, coll. S. Oh. Host plants. Unknown Distributions. Korea (Central) Remarks. This species was collected with a light trap in a mixed maple and oak forest. It is similar to Eurhadina koreana Dworakowska 1971, but differs as follows: 1) preapical process branched 3 parts and extended dorsolaterad; 2) apical process shorter than preapical process and U-shaped; 3) forewing oblique line not extended to anteapical cell; 4) pygofer side distinctly bilobed apically.
