( Figs. 23–33View FIGURES 23–33)

Description. General coloration white. Crown pale brown, with two dark brown round spots on laterad of coronal suture, surrounded by irregular milky white patch. Face with frontoclypeus, lora, genae and anteclypeus rather ivory in tint, not clearly distinguishable by color. Pronotum mainly subhyaline, with light ivory patches along anterior and lateral margins, with two large irregular milky white patches medially, and a broad irregular stripe posteriorly. Scutellum pale brownish, with pair of subtriangular dark brown patches basally; apex with a round dark brown patch; scutellar suture prominant. Forewing subhyaline, with pale whitish veins, and pale brown irregular zigzag pattern concentrated on clavus and apical cells; hindwing hyaline. Second sternal apodeme in male with posterior lobes not well developed, extended beyond second sternite.

Male genitalia. Pygofer lobes reaching 2/3 of subgenital plate posteriorly in lateral view; dorsal margin slightly concave; caudodorsal margin roundly produced without macrosetae on surface; dorsal processes elongate, gently curved downwards, gradually narrowed apically, with 5 sharp spines at outer surface distally. Subgenital plate with 3 macrosetae on outer base, more or less upcurved laterally. Style with inner apical process slender and sharply pointed, about 1.5 times as long as outer one. Connective U-shaped, with long parallel arms. Aedeagal shaft with pair of long apical processes continuous with contour of shaft basad of gonopore; subapical processes absent; basal paired processes stout and hooked.

Length. male 2.8–3.0mm, female 2.9–3.1mm.

Type Material. Holotype male, Korea: Gangwon Province, Deokgasan , 28.V.2016, Y.J. Kwon  ; Paratypes, 1 male & 3 females, same data as holotype  ; 2 males and 3 females, 20.VIII.2016, same locality and collector  .

Distribution. Korea (Central).

Etymology. The species name is derived from Latin adjective ‘spinosus’ (thorny, prickly) referring to its pygofer process possess with several stout spines.

Host plant. Unknown.

Remarks. This species is very similar to Ziczacella katoi Dworakowska, 1979  but can be distinguished from the latter by the pygofer process of the male with 5 sharp spines on the dorsal surface, and with a longer and narrower apex; and by the acuminate (rather than obliquely truncate) apex of the aedeagus in lateral view.
