Hauptenia palgongsanensis sp. nov.

( Figs 12–22 )

Description. Body length (from apex of vertex to tip of tegmen): male 4.8–5.2 mm (N=10), female 5.1–5.6 mm (N=24). Tegmen length: male 4.3–4.6 mm (N=10), female 4.5–5.0 mm (N=24).

Coloration. General color dark brown. Vertex ( Fig. 12 ), pronotum, frons ( Fig. 13 ), clypeus and ventral aspect of thorax bright yellow. Rostrum yellow except apex fuscous. Eyes blackish brown, ocelli pale yellow. Mesonotum ( Fig. 12 ) dark brown to black, with median carina dark brown and lateral carinae very shortly yellow near pronotum. Tegmen ( Fig. 15 ) dark brown to black, often covered with whitish bloom that contributes to a bluish appearance, longitudinal veins dark brown to black. Wings ( Fig. 16 ) grayish white, vein dark brown. Legs yellow, apex of tarsi fuscous. Abdomen dark brown except posterior margin of each segment yellow. Genital segment brown to dark brown.

Head and thorax. Head with eyes distinctly narrower than pronotum (1:1.51), short. Vertex in dorsal view broadly trapezoidal, wider between basal angles than long in middle line (3.4:1), apical margin distinct, transversely carinate, posterior margin slightly concave, lateral carinae slightly elevated, disk slightly depressed. Frons longer in middle line than widest part (1.48:1), shorter than clypeus (1:1.46), disc depressed in entire length, lateral carinae strongly keeled. Clypeus distinctly carinate medially. Apical segment of rostrum longer than wide. Genae with projecting ear-shaped carinae under antennae. Antennae short, pedicel subglobose, flagellum originated from apical point. Lateral ocelli adjacent to eyes and antennal socket. Median length of pronotum less than that of vertex (1:1.25), anterior margin between eyes broadly convex, length behind eyes slightly greater than median length, disc with lateral and median carinae absent, oblique transverse carinae strongly elevated. Mesonotum dorsally elevated, depressed at posterior end, median longitudinal carinae slightly elevated, lateral carinae near pronotum very shortly visible then feeble posteriorly. Tegmen with Sc with 2 sectors, subcostal cell long, M with 4 sectors, tegmen longer than widest part (2.77:1). Wings with R reaching to apical margin, CuA with 3 terminals. Spinal formula of hind leg 7–6–5.

Male genitalia. Anal segment ( Figs 21, 22 ) moderately long, usually with apex not reaching level of apex of genital styles, broader at base in dorsal view than apex about 1.75:1, longer (including anal styles) than widest part at base (1.78:1), dorsolateral margin slightly convex medially; anal styles strongly tumed ventrad. Pygofer ( Fig. 21 ) in profile distinctly shorter dorsally than ventrally, dorsocaudal angle not produced. Aedeagus ( Figs 17, 18 ) with shaft curved, flagellum with 4 lobes and 4 processes; among 4 lobes, two of which short, flap and ovalshaped, with small dentate margin, extending half length of other lobes, and the other 2 lobes elongate with left one curved dorsad near apex and right one with dorsoapical angle stout, apical margin obliquely truncate, dorsocaudal angle produced into process; flagellum at base in left lateral view ( Fig. 17 ) with one process arising from left, the other from middle and shorter than left one (1:1.96), middle process visible from both sides, directed cephalad; in right lateral view ( Fig. 18 ) with two processes, one short at base, directed dorsad, visible from both sides, the other long, arising from the right, as long as left process, directed cephalad. Genital styles ( Figs 19, 20 ) symmetrical, short and stout, apical margin obliquely truncate, dorsocaudal angle produced into finger-shaped process, dorsobasal projection distad, apical hook broad at base.

Etymology. This species is named after the collection site of the holotype, Palgongsan (Mt. Palgong) in Korea.

Host plants. Unknown.

Distribution. Korea.

Remarks. This species is similar to H. fellea (Yang & Wu) but differs from the latter in the mesonotum dark brown to black (mesonotum yellow in fellea ); frons shorter in middle line than clypeus about 1:1.46 (frons shorter in middle line than clypeus about 1: 1.10 in fellea ); tegmen with vein M with 4 sectors (tegmen with vein M 3 with sectors in fellea ); flagellum of aedeagus with 4 lobes, two of which short, flap and oval-shaped, with small dentate margin, extending half length of other lobes, and the other 2 lobes elongated (flagellum of aedeagus with 2 elongated lobes in fellea ); flagellum at base in left lateral view with one process arising from left, the other from middle and shorter than left one about 1:1.96, middle process visible from both sides (in fellea , flagellum at base in left lateral view with one process arising from left, the other from middle and as long as left one about 1:1, middle process visible only from left side).
