Maiestas maritima sp. nov.

( Figs 7 A–K, 8)

Description. General coloration light yellowish grey. Crown with dark brownish oblique band noticeable on each side of median line near and parallel to anterior margin. Frontoclypeus with fuscous arcs. Pronotum greenish yellow with blackish patches near posterior margin. Scutellum greenish yellow with darker basal triangles in male. Forewings with veins margined by brown patches. Head wider than pronotum. Crown longer medially than next to eyes, nearly 0.9 times as long as interocular width in male, distinctly longer in female; anterior margin angularly rounded. Ocelli on anterior margin of head, close to eyes, visible on dorsal side. Frontoclypeus broad, nearly as long as width between antennal pits. Anteclypeus slightly tapering apically. Lora distinctly narrower than anteclypeus near base. Pronotum approximately 0.8 times as long as crown in male, shorter than crown in female, lateral margin carinate; anterior margin rounded; posterior margin slightly concave. Scutellum nearly as long as pronotum in male, shorter in female, with transverse suture slightly curved and depressed. Forewings generally macropterous in male, submacropterous in female. Second sternal apodeme with posterior lobes developed, reaching end of 3rd sternite.

Male genitalia. Pygofer lobes approximately 1.6 times longer than high in lateral aspect, with numerous macrosetae in apical half; hind margin somewhat oval. Subgenital plates rounded triangular, with 5–6 macrosetae and a few hair like setae alongside the lateral margin. Styles rather slender; preapical lobe well expressed, angulate, furnished with several setose hairs; apophyses gently narrowed to bluntly pointed apically, protruded with a tooth on ventral side at next middle portion. Connective slightly longer than adeagus. Aedeagal shaft swollen subbasally, then tapered to acute apex; apex slightly turned dorsad; gonopore indistinct.

Body length. Male 2.9 mm, female 3.3mm.

Type material. Holotype, male, Korea: Jeonnam Province, Sumun Beach , on Zoysia sinica , 23.VIII.2017, Y.J. Kwon ; Paratypes, 2 males, 4 females, same date as holotype; 8 males, 12 females, on Zoysia sinica , same locality, 14.X.2017; Chungnam Province : 2 males, 2 females, on Zoysia sinica , Yanggil-ri, Palbong-myeon, Seosan City, 29.IX.2017, all same collector.

Distribution. Korea (Central, South).

Host plant. Zoysia sinica (observed).

Etymology. The name of the species is derived from the Latin word “maritimus” referring to the seaside habitat of the type material.

Remarks. This species resembles M. latifrons but can be readily differentiated by the shape of the aedeagal shaft, by the male pronotum distinctly shorter than the crown, and by the posterior lobes of 2nd sternal apodeme reaching the end of the 3rd sternite in the male. In the latter species, the male pronotum is nearly as long as the crown, and the posterior lobes of the 2nd sternal apodeme reach the end of the 4th sternite. The new species is also distinctive in being sexually dimorphic in head proportions and wing shape.
