Maiestas borealis sp. nov.

( Figs 1 A–J)

Description. General coloration light brown. Crown with dark brownish patterns on anterior margin, on disc brown bands and spots on each side of mid line. Frontoclypeus with fuscous arcs. Pronotum with blackish patches. Scutellum with dark brown marks. Forewings with greyish veins; cells bordered with dark brown patches. Head slightly wider than pronotum. Crown longer medially than next to eyes, nearly 0.8 times as long as inter-ocular width; anterior margin angularly rounded. Ocelli close to eyes, on anterior margin of head, visible on dorsal side. Frontoclypeus broad, approximately as long as width between antennal pits. Anteclypeus slightly tapering apically. Lora distinctly narrower than anteclypeus near base. Pronotum slightly longer than crown; lateral margin carinate; anterior margin rounded; posterior margin slightly concave. Scutellum slightly shorter than pronotum, with transverse suture slightly curved and depressed. Forewing macropterous, with four apical and three anteapical cells; inner anteapical cell open basally; middle anteapical cell divided by crossvein. Second sternal apodeme in male with posterior lobes well developed, reaching nearly end of 3rd sternite.

Male genitalia. Pygofer lobe in lateral aspect approximately 1.3 times longer than high, with numerous short to long macrosetae in apical half; hind margin somewhat truncate. Subgenital plate subtriangular; lateral margin evenly convex, with several macrosetae. Style slender; preapical lobe acute, well expressed, with fine setae; apophysis rather short, with ventral tooth subapically. Connective longer than aedeagus. Aedeagal shaft rather broad, blade like, gently narrowed apically in ventral view; apex slightly turned dorsad; gonopore indistinct.

Body length. Male 3.2–3.3mm, female 3.7–3.8mm.

Type material. Holotype male, Korea, Gangwon Province: Balgyosan , 23.IX.2016, Y.J. Kwon ; Paratypes, 6 males, 4 females, same data as holotype; Chungbuk Province : 1 male, Cheondeungsan, 1.X.2016; Gyeongbuk Province : 1 male, KPNU campus, Daegu City, 16.IX.1981 ; 1 male, Daegu City, 13.IX.1983; Jejudo Province : 1 male, Donnaeko, 4.IX.1998; 1 male, Gwangryeong-Ri, on Zoysia sp., 19.II.2016; 2 males, 1 female, Hanlasan, 9.VIII.1984, all same collector.

Distribution. Korea (Central, South, Jejudo).

Host plant. Zoysia sp.

Etymology. The name of the new species is derived from Latin word “borealis” referring its northerly distribution in Asia.

Remarks. This species resembles M. yangae Zhang & Duan, 2011 , but can be readily differentiated from the latter by the style apophysis in having gently tapered apex and armed with a ventral tooth on subapex. Although it is abruptly tapered to apex from mid length, with a ventral tooth on next middle portion in the latter species. This species is also simlilar to M. horvathi ( Then, 1896) , but it differs from the latter in having a somewhat broader aedeagal shaft, less acute aedeagal apex and shorter style apophysis.
