Forewing subhyaline, with orange to yellowish orange patterns, and several black to dark brown spots on costal margin. Hindwing subhyaline. Venter and legs concolorous, whitish. Second sternal apodeme with posterior lobes large, parallel sided, ovoid at apex, reaching to hind margin of 5th sternite.

Male genitalia. Pygofer with apical margin dorso-caudad; dorsal margin slightly concave; ventral margin armed with long slender process, arising from caudoventral side, directed dorsally, gently tapered apically. Subgenital plate short and broad, with small apical part, with 2 macrosetae subbasally. Aedeagal shaft almost straight, narrowing terminally, armed with 3 apical slender processes, comprising terminal one directing apically, and two subterminal ones directing basally; gonopore subapical on ventral surface. Style long, slightly curved, with several microsetae medially; apex with sharp angled edge subapically. Connective Y-shaped, with small central lobe.

Body length. Male 2.8‾ 3.1mm, female 3.0‾ 3.3mm.

Type material. Holotype male, Korea: Chungbuk Province, Jincheon , on Diospyros kaki , 14.VIII.2008, Y.J. Kwon ; Paratypes, 8 males & 14 females, same data as holotype; Gyeonggi Province : 2 males, Camp Humphreys, 23. VI.2016, H.C. Kim; Jeonnam Province : 9 males & 6 females, Illimsan, on Diospyros kaki , 23.VIII.2018, Y.J. Kwon.

Distribution. Korea (South, Central).

Host plant. Diospyros kaki (Persimmon) .

Remarks. This species is similar to L. kakii Chou et Ma, 1981 , but differs in having the aedeagus shaft with 3 apical processes. The new species is the second one known to dwell on persimmon trees in Asia, and it is considered as an occasional pest with sporadic occurrence in Korea so far.
