L. (Limassolla) dangjinensis sp. nov. Oh et Jung

( Figs. 12 ~22)

Description. Vertex and pronotum yellowish orange with pale yellow patterns, vertex with 3 pale yellow spots and pronotum with five round pale yellow spots. Mesonotum yellowish orange with small and narrow pale yellow pattern, scutellum pale yellow ( Fig. 12 ). Face pale yellow and gena almost white. Legs whitish yellow and abdomen yellow with pale yellow strips ( Fig. 13 ). Forewing with complex pattern including yellowish orange maculae and dark brown lines ( Fig. 14 ). Male abdominal apodemes large and extended to 6th segment ( Fig. 20 ).

Male genitalia. Pygofer lobe wide truncate distally, appendage relatively wide basally, sinuate distally ( Fig. 18 ). Subgenital plate narrow with several macrosetae on middle part and several microsetae on apical margin ( Fig. 22 ). Style with several microsetae on middle of outer margin and distal margin of apex flat ( Fig. 19 ). Aedeagus shaft slender and elongate in lateral and posterior view, apex with two pairs of short processes, one extending distad and the other extending basad and bent inward ( Fig. 16, 17 ). Connective small and star-shaped with six lobes, including thin anterior median lobe ( Fig. 21 ).

Measurements. Body length male 3.14~ 3.28mm, female 3.22~ 3.56mm.

Type materials. Holotype: [ CNU] ♂, Korea, Chungcheongnam-do, Dangjin-si, Sunseong-myeon, Seonguk-ri on Diospyros kaki THUNB , 11.ix. 2015, coll. S. Oh. Paratype: [ CNU] 2♂♂, 22♀♀, same data as holotype .

Host plants. Diospyros kaki THUNB * ( Ericales : Ebenaceae ).

Bionomics. This species was not found in persimmon orchards, but was found on a persimmon tree in native forest and caused feeding injury to the tree ( Fig. 23–B ).

Distribution. Korea *.

Remarks. This new species is similar to two previously described Limassolla species in general appearance. It differs from L. hebeiensis Cai, Liang & Wang, 1992 as follows: 1) pygofer appendage sinuate, 2) style curved gently with several microsetae on outer margin, 3) aedeagus processes short and lower process bent inward, 4) connective with six lobes, 5) male abdominal apodemes extended to 6th segment. It differs from L. diospyri Chou & Ma, 1981 as follows: 1) pygofer appendage sinuate, 2) aedeagus processes curved in caudal view, 3) aedeagus processes branched below apex, 4) connective with six lobes, 5) male abdominal apodemes extended to 6th segment.

Etymology. The specific name is derived from that of the type locality.
