Hauptenia tripartita sp. nov.

( Figs 23–33 )

Description. Body length (from apex of vertex to tip of tegmen): male 4.8–5.1 mm (N=22), female 5.0– 5.5 mm (N=21). Tegmen length: male 4.2–4.5 mm (N=22), female 4.5–4.9 mm (N=21).

Coloration. General color yellowish brown. Vertex ( Fig. 23 ), pronotum, frons ( Fig. 24 ), clypeus and ventral aspect of thorax yellow. Rostrum yellow except apex fuscous. Eyes blackish brown, ocelli pale yellow. Mesonotum ( Fig. 23 ) yellowish brown. Tegmen ( Fig. 26 ) yellowish brown, often with white waxy powder, longitudinal veins brown. Wings ( Fig. 27 ) grayish white, veins brown. Legs yellow. Abdomen yellowish brown with lateral margin tinged with dark brown or red. Genital segment yellow brown.

Head and thorax. Head with eyes distinctly narrower than pronotum (1:1.54), short. Vertex in dorsal view broadly trapezoidal, wider between basal angles than long in middle line (3.28:1), apical margin distinct, transversely carinate, posterior margin concave, lateral carinae slightly elevated, disk slightly depressed, median carina very feeble. Frons longer in middle line than widest part (1.84:1), shorter than clypeus (1:1.1), disc depressed in entire length, lateral carinae strongly keeled. Clypeus distinctly carinated medially. Apical segment of rostrum longer than wide. Genae with projecting ear-shaped carinae under antennae. Antennae short, pedicel oval-shaped, flagellum originated from apical point. Lateral ocelli adjacent to eyes and antennal socket. Median length of pronotum about equal to that of vertex (1:1), 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 feeble. Tegmen with Sc with 2 sector, subcostal cell long, M with 3 sectors, tegmen longer than widest part (2.89:1). Wings with R reaching to apical margin, CuA with 3 terminals. Spinal formula of hind leg 7–6–5.

Male genitalia. Anal segment ( Figs 32, 33 ) moderately long, usually with apex not reaching level of apex of genital styles, broader at base in dorsal view than apex about 2.21:1, longer (including anal styles) than widest part at base (2:1), lateral margin slightly concave medially; anal styles slightly turned ventrad. Pygofer ( Fig. 33 ) in profile distinctly shorter dorsally than ventrally, dorsocaudal portion without any process. Aedeagus ( Figs 28, 29 ) with shaft gently curved; flagellum of aedeagus with 4 lobes and 6 processes, among 4 lobes, two of which short, flap and oval-shaped, with small dentate margin, medium lobe with apicoventral portion produced into process directing dorsad, and the other one elongate, wide, tripartite, reaching nearly to base of aedeagus; flagellum at base in left lateral view ( Fig. 28 ) with three processes arising from left: one long and the other two short, all directed cephalad; in right lateral view ( Fig. 29 ) with three processes: one long, directed ventrad, other two short, directed dorsad. Genital styles ( Figs 30, 31 ) symmetrical, short and stout, apical margin obliquely truncate, dorsoapical process indistinct, dorsobasal projection reaching to level of apical margin of styles.

Etymology. The Latin word ‘ tripartita ’ means ‘divided into three parts’. Named after an elongate and tripartite lobe of flagellum of aedeagus reaching nearly to base of aedeagus.

Host plants. Unknown.

Distribution. Korea.

Remarks. This species is similar to H. magnifica (Yang & Wu) but can be distinguished from the latter by the shape of aedeagus, especially by the shape of an elongated, wide, and tripartite lobe of flagellum reaching near to base of aedeagus.
