Material examined.

Holotype, female, China: Liaoning Province, Haicheng City, Jiulongchuan , 40.624°N, 123.096°E, 650 m, 10 May 2017, leg. Zejian Li (ASMN).

Diagnosis.

This new species is most similar to A. malaisei (Gussakovskij, 1947) but differs from the latter by the following characters: the lateral sides and posterior end of mesoscutal middle lobe and the inner side of mesoscutal lateral lobes yellowish brown; the dorsum of head with a narrow M-shaped black macula; the pale lateral stripe and pale posterior margin of the first abdominal tergum connected in front of the roundish lateral black macula; the third tergum with a distinct lateral pale macula, the pale macula on terga 6-8 distinct and about 4 × broader than long; cenchri broad, distance between cenchri 2.2 × the longest axis of a cenchrus; distance between the middle serrulae narrower than 2 × the breadth of a serrula; and the total length of annuli of lance 4.8 × height of 13th annulus.

Description.

Holotype, female. Body length 20.5 mm (Fig. 9A ).

Color. Head and antenna orange brown, dorsum of head with a narrow M-shaped black macula, clypeus yellowish brown (Fig. 9B, C ); thorax black, posterior margin and lateral lobe of pronotum, tegula, lateral sides and posterior end of mesoscutal middle lobe and inner side of mesoscutal lateral lobe, mesoscutellum and dorsum of metascutellum, mesepisternum above carina largely, posterior half of katepimeron, lower part of metepisternum, middle of mesosternum yellowish brown (Fig. 9D, G ); abdomen yellowish brown, following parts black: a transverse anterior band and a small round lateral macula on tergum 1, tergum 2 entirely, tergum 3 except for lateral small macula, a large triangular middle macula and narrow posterior margin of tergum 4, tergum 5 except for narrow anterior margin, lateral macula on terga 6-8 (Fig. 9E ), an anterior small macula on ventral fold of terga 3-8 (Fig. 9H ), and basal macula on sterna 3-7; pale middle macula of terga 6-8 same size, about 3 × broader than long. Fore wing distinctly infuscate, cells 2M, 3M, 2Cu and 2A largely subhyaline, veins and pterostigma largely brown to pale brown; hind wing weakly infuscate at apex (Fig. 9A ); legs largely yellowish brown, middle and hind coxae with black longitudinal stripes ventrally and dorsally, trochanters and femora largely blackish brown (Fig. 9A, H ).

Head. Dorsum of head with minute punctures, clypeus smooth with strong luster (Fig. 9B, C ). Clypeus elevated, anterior margin narrowly and deeply incised; labrum small and triangle, long than broad; malar space 1.8 × diameter of middle ocellus; postocellar area 2.1 × broader than long, middle furrow weak; lateral furrows distinct, slightly divergent backwards; POL: OOL: OCL = 3.5: 4: 6; head behind eyes weakly enlarged (Fig. 9B, C ); antenna 1.6 × head breadth, club breadth 2.4 × apical breadth of antennomere 3, club length 1.3 × length of antennomere 3 (Fig. 9F ), antennomere 3 as long as longest axis of eye.

Thorax. Mesonotum very densely punctured (Fig. 9D ), mesopleuron densely and minutely punctured, interspaces between punctures microsculptured; mesoscutellum roundly elevated, without middle furrow; mesopleuron with a distinct oblique carina; cenchrus elliptical, distance between inner margin of cenchri 2.2 × longest axis of a cenchrus.

Abdomen. Abdominal tergum 1 with minute punctures and microsculptures, other terga finely and densely microsculptured, ovipositor sheath largely smooth (Fig. 9E, H ). Tergum 1 with low but distinct lateral carina, anterior corner roundish; posterior margin very deeply and roundly incised (Fig. 9E ); middle process of sternum 7 broad and triangular, basal breadth about 1/3 breadth of sternite 7; lance narrow and long, subapical annuli clearly broadened, total length of annuli 4.8 × height of 13th annulus, first annulus 1.5 × as high as broad (Fig. 9K ); lancet with 47 serrulae (Fig. 9K ), middle serrulae weakly narrowed toward truncate apex, each side with 3-4 large subbasal teeth, distance between middle serrulae 1.8 × basal breadth of serrulae (Fig. 9L ).
