Material examined.

Holotype, female, China: Liaoning Province, Benxi, Mt. Bapanling , 16 May 2017, Ruifen Huang (ASMN).

Diagnosis.

A. maculotegularis Yan & Wei sp. nov. is close to A. eous (Semenov, 1935) but differs from the latter by the following characters: Tegula largely black; the lateral side of the first abdominal tergum yellowish brown; the 4th abdominal tergum with a small middle black macula; the middle and hind tibiae reddish brown; the first abdominal tergum with middle part distinctly produced; lancet with 51 serrulae, distance between the middle serrulae 2.2 × breadth of a serrula.

Description.

Holotype, female. Body length 18.5 mm (Fig. 10A ).

Color. Head and antenna dark yellowish brown, dorsum with a subquadrate black macula covering ocellar area, frons, inner half of inner orbit, lateral and middle foveae, clypeus and mouthparts largely yellow brown (Fig. 10C, E ); thorax black, pronotum largely, anterior third of tegula, mesoscutellum, dorsum of metascutellum, posterior half of mesepisternum above carina and posterior half of katepimeron, posterior stripe of metepisternum yellowish brown (Fig. 10B, F ); dorsum of abdomen black, lateral margin of tergum 1, 4th tergum except for middle triangular macula, 5th tergum almost entirely and middle third of terga 6-8 pale yellowish brown, lateral part of terga 6-8 blackish brown (Fig. 10G, H ), venter of abdomen dark brown, lateral macula on sterna 4-6 and sternum 7 yellowish brown (Fig. 10I ); fore wing distinctly infuscate in anterior half, outer margin without narrow smoky macula, cells 2M, 3M, 2Cu and 2A largely subhyaline, veins and pterostigma pale brown; hind wing very feebly infuscate; legs largely yellowish brown, middle and hind coxae, trochanters and femora largely black (Fig. 10A ).

Head. Dorsum of head with minute punctures, clypeus largely smooth, with strong luster (Fig. 10B, C, E ). Clypeus elevated, anterior margin roundly incised; labrum small and triangular, slightly broader than long; malar space 1.7 × diameter of middle ocellus; postocellar area 2.1 × broader than long, middle furrow weak; lateral furrows distinct, divergent backwards; POL: OOL: OCL = 3: 5: 6; head behind eyes weakly enlarged (Fig. 10C ); antenna 1.6 × head breadth, club breadth 2 × apical breadth of antennomere 3, club length 1.1 × as long as antennomere 3 and 1.38 × the combined length of antennomeres 4 and 5 (Fig. 10D ), antennomere 3 as long as longest axis of eye.

Thorax. Mesonotum densely punctured (Fig. 10B ); scutellum strongly elevated with a broad and deep middle furrow, sparsely punctured; mesepisternum above carina densely but shallowly punctured mixed with microsculptures, oblique carina on mesopleuron sharp, mesepimeron largely polished, shiny (Fig. 10F ); cenchri elliptical, distance between inner margin of cenchri 2.3 × the longest axis of a cenchrus (Fig. 10B ).

Abdomen. Abdominal tergum 1 minutely punctured mixed with microsculptures, without lateral smooth patch; lateral carina low but recognizable, anterior corner blunt, posterior corner roundish; posterior margin with broad and incision, bottom not round with obtuse middle process (Fig. 10G, H ); middle process of sternum 7 narrow and triangular, basal breadth about 1/6 breadth of sternite 7; lance long and slender, subapical annuli clearly broadened, total length of annuli 5.3 × height of 13th annulus, first annulus 1.8 × as high as broad (Fig. 10J ); lancet with 52 annuli and 51 serrulae (Fig. 10J ), 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. 10K ).
