Empoasca (Empoasca) giusana Hossain et al. , sp. nov.

( Figs. 1–13 )

Description. Body yellowish green in ground color. Crown with dark green patch on each side of coronal suture. Eyes dark. Frontoclypeus yellowish with dark patches; anteclypeus, lorum and genae pale green to dark green. Pronotum with dark greenish irregular patches on anterior margin and under eyes. Forewing and hindwing semitransparent. Abdomen and legs light green to greenish. Second sternal apodemes in male with posterior lobes subparallel-sided, relatively long; apex round, reaching to middle of 5th sternite.

Male genitalia. Pygofer lobes with posterior margin broadly rounded in lateral view, with 6–8 stout setae in group along posterior margin; ventral pygofer process very characteristically bipartite subapically, processes cross each other medially, just exceeding posterior margin of pygofer lobe; branches of pygofer process unequal in length apically both in lateral and ventral view, close with each other. Anal tube with process branched in saggital plane, branches long and smooth, more or less straight, subparallel each other, extended ventrad. Subgenital plate curved caudodorsad in lateral view, expanded apically, with numerous macrosetae and fine setae somewhat irregularly arranged; dorsolateral margin with 5–6 long stout setae subbasally, and 14–16 short microsetae on apical 2/3. Style with 5–7 teeth on dentifer, 8–10 sparse setae subapically, with base slightly sinuate. Connective broad, with anterior margin emarginate medially, strongly sclerotized along mid-line but without obvious dorsal keel. Aedeagal shaft straight, with preatrium long, curved dorsad in lateral view, 1.5 times longer than maximum width of shaft; gonopore apical, on ventral surface.

Length. Male 3.2–3.3mm; female 3.2–3.3mm.

Type material. Holotype male, Korea, Gangwon Province: Giusan , 8.X.2016, Y.J. Kwon ; Paratypes, 2 males & 5 females, same data as holotype .

Distribution. Korea (Central).

Host plant. Unknown.

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

Remarks. This species is similar to E. fissurata Dworakowska, 1968 , but differs from the latter by the longer and straight anal tube process, and by the ventral pygofer processes in being crossed each other.
