Produsa koreana sp. nov.

( Figs 1–11 )

Description. Body length (from apex of vertex to tip of tegmen): male 4.8–5.0 mm (N=08), female 5.0– 5.4 mm (N=10). Tegmen length: male 4.2–4.5 mm (N=08), female 4.5–4.9 mm (N=10).

Coloration. General color dark brown. Vertex ( Fig. 1 ) dark brown at middle, lateral and transverse carinae golden yellow. Frons and clypeus ( Fig. 2 ) dark brown with median line and lateral carinae yellow. Rostrum yellowish brown with apex fuscous. Genae yellowish brown, projecting with pale yellow ear-shaped lobe under antennae. Eyes blackish brown, ocelli pale yellow. Antennae brown to dark brown at base, yellowish brown at apex. Pronotum ( Fig. 1 ) dark brown with margins and transverse carinae golden yellow. Mesonotum ( Fig. 1 ) blackish brown. Tegmen ( Fig. 4 ) brown to dark brown, with white waxy powder, longitudinal veins dark brown to black. Wings ( Fig. 5 ) grayish white, veins pale black. Thorax with ventral areas brown to fuscous. Legs yellow, femura and tarsi brown. Abdomen dark brown, with lateral margin and posterior of margin of each segment yellowish brown. Genital segment yellowish brown to dark brown.

Head and thorax. Head with eyes distinctly narrower than pronotum (1:1.5), short. Vertex in dorsal view broadly trapezoidal, wider between basal angles than long in middle line (5.4:1), apical margin distinctly carinate, posterior margin concave, lateral carinae slightly elevated, disk slightly depressed, median carina very feeble. Frons longer in middle line than widest part (1.57: 1), shorter than clypeus (1:1.2), 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. Pronotum with median length 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 very feeble. Tegmen with Sc with 1 sector, subcostal cell long, M with 4 sectors, tegmen longer than widest part (2.68:1). Wings with R reaching to apical margin, CuA with two terminals. Spinal formula of hind leg 6–5–5.

Male genitalia. Anal segment ( Fig. 9 ) moderately long, usually with apex not reaching level of apex of genital styles, broader at base in dorsal view than apex about 1.77:1, longer (including anal styles) than widest part at base (2.03:1), lateral margin slightly concave medially; anal styles directed caudad. Pygofer ( Fig. 8 ) in profile distinctly shorter dorsally than ventrally, at dorsocaudal portion produced caudad in small process, directed caudad. Aedeagus ( Figs 6, 7 ) with shaft gently curved, with 3 short processes at apex, most part of apical processes visible in both left and right lateral view; flagellum with 2 lobes, dorsal one armed with a small process at dorsal median portion, apex bifurcate, unequally branched, outer process shorter than inner one (1:2.10), inner process comparatively wide with lobe-like extension at middle, ventral lobe with apex equally branched, both processes almost same in length. Oval and flap-like process present at base of flagellum in left lateral view ( Fig. 6 ). Genital styles ( Figs 10, 11 ) symmetrical, slender, apical margin acute, in caudal view turned mesad acutely, inner margin of genital styles in ventral view well developed and lobed, dorsobasal projection basad, with apical process widening to base, basal process visible in profile.

Kwon; 1 male, 3 females, Unjangsan, Jeollabuk–do Province, 28 Aug. 1998, Y.J. Kwon; 1 female, Songnisan, Chungcheongbuk–do Province, 9 Sep. 2001, Y.J. Kwon (KNU).

Etymology. The species is named for its occurrence in Korea.

Host plants. Unknown.

Distribution. Korea.

Remarks. This species is similar to P. cubica (Yang & Wu) but differs from the latter in the aedeagus at apex in left lateral view with only 2 processes visible among 3 processes (aedeagus at apex in left lateral view with all 3 processes visible in cubica ); dorsal lobe of flagellum of aedeagus unequally branched at apex and ventral lobe equally branched (in cubica , dorsal lobe of flagellum of aedeagus equally branched at apex and ventral lobe unequally branched); outer process of dorsal lobe of flagellum of aedeagus at apex shorter than inner one about 1:2.10, inner process comparatively wide with lobe-like extension at middle (in cubica , outer process of dorsal lobe of flagellum of aedeagus at apex longer than inner one about 1.45:1, inner process comparatively narrow, without a lobe-like extension at middle); and base of flagellum in left lateral view with oval and flap-like process (absent in cubica ).
