description: Asicimbex koreanus Yan &amp; Wei sp. nov. Fig. 7 Material examined. <i>Holotype</i>, female, South Korea: [GG] Hwaseong-gun, 24 May 1992, H. J. Lee (YNU). <i>Paratypes</i>, 4 females and 1 male, data as holotype. Diagnosis. <i>A. koreanus</i> Yan &amp; Wei sp. nov. is quite close to <i>A. malaisei</i> (Gussakovskij, 1947) comb. nov. from Ussuri of Russia. It differs from the latter by the following characters: the apical club of antenna longer than antennomere 3 and about 1.6 × as long as antennomeres 4 and 5 together; cenchrus very narrow and about 4 × as long as broad; the dorsum of mesoscutellum densely punctured; the upper half of mesepisternum densely punctured mixed with wrinkles; the lateral carina of the first abdominal tergum roundly curved, the anterior corner not angulate; the apex of the middle process of the seventh sternum acute; the black macula on dorsum of head not subquadrate, with three processes; the apical margin of fore wing without smoky macula; lancet with 56 serrulae, the distance between middle serrulae broader than 2 × breadth of a serrula. Description. <b>Holotype, female.</b> Body length 21 mm (Fig. 7A). <b> <i>Color</i>.</b> Head and antenna yellowish brown, dorsum with a M-shaped black macula, clypeus and mouthparts largely yellow brown (Fig. 7C, E); thorax largely black, narrow posterior margin and broad lateral margin of pronotum, anterior part of tegula, mesoscutellum, dorsum of metascutellum, posterior 3/4 of mesepisternum above carina and posterior half of katepimeron, metepisternum largely yellowish brown (Fig. 7F); abdomen yellowish brown, dorsal side of terga 1-3 entirely, broad triangular middle macula on tergum 4 and narrow basal margin of tergum 5 black, narrow lateral margin of tergum 1, tergum 4 except for middle triangular macula, tergum 5 almost entirely, broad quadrate middle macula on terga 6-8 pale yellow brown, lateral part of terga 6-8 dark brown (Fig. 7G, H), sterna largely dark brown (Fig. 7I); fore wing distinctly infuscate, outer margin of fore wing without narrow smoky maculae, cells 2Rs, 3Rs, 2M, 3M, 1Cu, 2Cu and 2A largely subhyaline, veins and pterostigma pale brow; hind wing very feebly infuscate; legs largely yellowish brown, middle and hind coxae, trochanters and femora largely black, tarsi yellowish white (Fig. 7A, J). <b> <i>Head</i>.</b> Dorsum of head with minute punctures, clypeus smooth, with strong luster (Fig. 7C, 7E). Clypeus elevated, anterior margin roundly incised; labrum as long as broad, apex round; malar space 1.7 × diameter of middle ocellus; postocellar area 2 × broader than long, middle furrow weak; lateral furrows distinct, feebly divergent backwards; POL: OOL: OCL = 3: 5: 6; head behind eyes weakly enlarged (Fig. 7C). Antenna 1.6 × head breadth, club breadth 2.2 × apical breadth of antennomere 3, club length 1.1 × as long as antennomere 3 and 1.6 × combined length of antennomeres 4 and 5 (Fig. 7D), antennomere 3 as long as longest axis of eye. <b> <i>Thorax</i>.</b> Mesonotum minutely and densely punctured (Fig. 7B); scutellum roundly elevated without middle furrow, dorsum densely punctured; mesepisternum above carina densely and minutely punctured mixed with microsculptures, oblique carina on mesopleuron sharp, mesepimeron largely polished, shiny (Fig. 7F); cenchri very narrow and about 4 × as long as broad, distance between inner margin of cenchri 2.8 × longest axis of a cenchrus (Fig. 7B). <b> <i>Abdomen</i>.</b> Abdominal tergum 1 minutely punctured mixed with microsculptures, without lateral smooth patch; lateral carina low and obtuse, anterior and posterior corners round, posterior margin with broad and deep incision, bottom round (Fig. 7G); middle process of sternum 7 broad and triangular, basal breadth about 1/3 breadth of sternite 7; lance long and slender, subapical annuli clearly broadened, total length of annuli 5.4 × height of 13th annulus, first annulus 1.8 × as high as broad (Fig. 7L); lancet with 57 annuli and 56 serrulae (Fig. 7L), middle serrulae weakly narrowed toward truncate apex, each side with 4-5 large subbasal teeth, distance between middle serrulae 2.2 × basal breadth of serrulae (Fig. 7M). <b>Male.</b> Color and structure similar to female. Genitalia not examined. Distribution. South Korea. Host plant. Unknown.
