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

( Figs. 14–26 )

Description. Body elongate, slender; shiny yellowish-green in ground color. Crown roundly produced medially, with brownish patch on anterior margin and each side of coronal suture. Eyes brown. Face concolorous, with lateral margins of anteclypeus whitish. Pronotum with irregular patches on anterior margin and under eyes. Scutellum with cream-yellowish triangular spots laterally. Forewing and hindwing semitransparent. Abdomen and legs pale yellow to yellow. Second sternal apodeme in male with posterior lobes well developed, parallel-sided, reaching to middle of 5th sternite.

Male genitalia. Pygofer with ventral process slightly shorter than pygofer lobes in lateral view, curved caudad apically and tapering to apex. Anal tube with processstout, widened at base, swollen distinctly in sub-apical part, narrowing apically with blunt apex. Subgenital plate curved distinctly caudodorsad, not expanded apically in lateral view, tapered to narrow apex, 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 and subapical parts. Style sinuate, with apex bearing 6 teeth on dentifer, preceded by about 6–8 setae subapically. Connective broad, with anterior margin emarginated medially. Aedeagal shaft well sclerotized, with a pair of long processes arising from preatrium on ventral side exceeding the shaft; preatrium thick in lateral view; postatrium distinctly flattened plate-likely; shaft at base strongly divergent from line of atrial complex, but thence straight with widened apex; gonopore apical, on ventral surface.

Length. Male 3.1–3.3mm, female 3.3–3.5mm.

Type material. Holotype male, Korea, Gyeongbuk Province: Chilgok-gun, Gasan-myeon, Gasan-Ri, Palgongsan, 22.IX.2011, Y.J. Kwon; paratypes, 3 males, 3 females, same data as holotype; 6 males, 12 females, Daegu City, Joya-dong, Geumhogang, 22.IX.2011, all same collector.

Distribution. Korea (South).

Host plant. Unknown.

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

Remarks. This species is similar to E. longa Zhang and Liu, 2011 , but differs from the latter by the longer preatrial processes and widened shaft of aedeagus, and by the smooth posterior surface of anal tube processes. It also differs from latter in absence of microseatae in pygofer ventral appendage (presence of a few microsetae in pygofer ventral appendage in E. longa ).
