description: Asicimbex malaisei (Gussakovskij, 1947) comb. nov., New record for China Fig. 11 Agenocimbex malaisei Gussakovskij, 1947: 30, 32. Material examined. 1 female, China: Heilongjiang Province, Shangzhi, Mt. Mao’er, 4 June 2014, leg. Jun Xu (ASMN). Diagnosis. This new species is most similar to <i>A. koreanus</i> Yan &amp; Wei sp. nov. but differs from the latter by the following characters: the black macula on dorsum of head subquadrate; the apical club of antenna as long as antennomere 3, about 1.3 × as long as antennomeres 4 and 5 together; cenchrus normal, about 3 × as long as broad; the dorsum of mesoscutellum sparsely punctured; the upper half of mesepisternum sparsely punctured, wrinkles indistinct; the lateral carina of the first abdominal tergum roundly curved only in posterior half, anterior corner angulate; lancet with 48 serrulae, the distance between the middle serrulae about 2 × breadth of a serrula; lance slender with the first annulus 1.8 × as high as broad. Description. <b>Not type, female.</b> Body length 21 mm (Fig. 11A). <b> <i>Color</i>.</b> Head and antenna yellowish brown, dorsum with a subquadrate black macula, clypeus and mouthparts largely yellow brown (Fig. 11C, E); thorax largely black, very narrow posterior margin and narrow lateral margin of pronotum, mesoscutellum, dorsum of metascutellum, posterior 3/4 of mesepisternum above carina and posterior stripe of katepimeron, metepisternum largely dark brown (Fig. 11B, F); abdomen mostly dark 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 yellowish brown, broad quadrate middle macula on terga 6-8 pale brown (Fig. 11G), lateral part of sterna 4-6 and most of sternum 7 pale brown (Fig. 11H, K); fore wing infuscate in anterior half, outer margin of fore wing with narrow smoky macula, cells 2Rs, base of 3Rs, 2M, most of 3M, apical 2/5 of 1Cu, 2Cu and 2A largely subhyaline, veins and pterostigma pale brown; hind wing faintly infuscate; legs largely yellowish brown, middle and hind coxae, trochanters and femora largely black, tarsi largely yellowish white (Fig. 11A, I, J). <b> <i>Head</i>.</b> Dorsum of head with minute punctures, clypeus smooth, with strong luster (Fig. 11C, E). Clypeus elevated, anterior margin roundly incised; labrum as long as broad, apex round; malar space 1.5 × 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 distinctly enlarged (Fig. 11C). Antenna 1.5 × head breadth, club breadth 2.2 × apical breadth of antennomere 3, club length 1.1 × as long as antennomere 3 and 1.3 × combined length of antennomeres 4 and 5 (Fig. 11D), antennomere 3 as long as longest axis of eye. <b> <i>Thorax</i>.</b> Mesonotum minutely and densely punctured (Fig. 11F); scutellum roundly elevated without middle longitudinal furrow, dorsum densely punctured, anterior slope sparsely punctured; mesepisternum above carina sparsely punctured, wrinkles indistinct; oblique carina on mesopleuron sharp, mesepimeron largely polished, shiny (Fig. 11B); cenchri very narrow and about 4 × as long as broad, distance between inner margin of cenchri 3 × longest axis of a cenchrus (Fig. 11B). <b> <i>Abdomen</i>.</b> Abdominal tergum 1 minutely punctured mixed with microsculptures, without lateral smooth patch; lateral carina low and obtuse, anterior corner angulate, posterior corner round, posterior margin with broad and deep incision, bottom round (Fig. 11G); middle process of sternum 7 broad, apex roundish, basal breadth about 1/3 breadth of sternite 7 (Fig. 11K); lance long and slender, subapical annuli clearly broadened, total length of annuli 5.2 × height of 13th annulus, first annulus 1.5 × as high as broad (Fig. 11M); lancet with 57 annuli and 56 serrulae (Fig. 11M), middle serrulae weakly narrowed toward truncate apex, each side with 3-4 large subbasal teeth, distance between middle serrulae 2 × basal breadth of serrulae (Fig. 11N). <b>Male.</b> Color and structure similar to female. Genitalia not examined. Description of male see (Gussakovskij 1947). Distribution. China (Heilongjiang); Russia (Ussuri). Host plant. Unknown. Remarks. Gussakovskij (Gussakovskij 1947) described this species and discussed the possibility of it being the male of <i>Asicimbex eous</i> (Semenov 1935). But, the difference with <i>A. eous</i> are the outer margin of fore wing with narrow smoky macula; the mesoscutellum without middle longitudinal furrow, dorsum densely punctured; anterior slope sparsely punctured; the middle process of female sternum 7 narrow triangular, basal breadth much shorter than height and about 1/6 breadth of the sternum; the pattern of subbasal teeth, distance between middle serrulae 2 × basal breadth of serrulae; the lateral carina of abdominal tergum 1 low and obtuse, anterior corner angulate, posterior corner round. These characteristics indicate that <i>A. malaisei</i> and <i>A. eous</i> are distinct species.
