Fig. 4 View Figure 4
Material examined.
Holotype female, China: Liaoning Province, Shenyang City, Dongling 23 May 1989, leg. Meicai Wei (ASMN).
Diagnosis.
This species is quite similar to A. eous (Semenov, 1935) and A. maculotegularis Yan & Wei sp. nov., but differs from the latter two species by the following characters: the black macula on dorsum of head small and not subquadrate, frontal ridges pale; mesepisternum entirely black; the apical margin of fore wing with narrow smoky macula; mesoscutellum roundly elevated without middle furrow; lancet with 48 serrulae, serrulae distinctly narrowed toward apex, distance between middle serrulae about 1.5 × breadth of serrula; lance slender, the subapical part not broadened, and the first annulus 2.1 × as high as long.
Description.
Holotype, female. Body length 21 mm (Fig. 4A View Figure 4 ).
Color. Head dark yellowish brown, frontal area with a M-shaped narrow black maculae, clypeus and mouthparts largely yellowish brown (Fig. 4E View Figure 4 ), antenna reddish brown (Fig. 4D View Figure 4 ); thorax largely black, narrow posterior and lateral margins of pronotum, tegula, mesoscutellum, dorsum of metascutellum, narrow posterior margin of mesopleuron yellowish brown (Fig. 4G, H View Figure 4 ); abdomen dark yellowish brown, terga 1-2 entirely, tergum 3 except for lateral small macula, subtriangular middle macula on tergum 4 and narrow basal margin of tergum 5 black, lateral macula on terga 7-8 and most of ventral fold of terga 2-6 blackish brown (Fig. 4A, L View Figure 4 ), pale maculae at middle of terga 6-8 3 × broader than long. Wings smoky, outer margin of fore wing with a narrow and weak smoky macula (Fig. 4C View Figure 4 ), cells 3Rs, 2M, 3M, 1Cu, 2Cu and A largely subhyaline, veins and pterostigma pale brow; legs largely yellowish brown, coxae with black longitudinal stripes, trochanters and femora largely blackish brown.
Head. Dorsum of head with indistinct and minute punctures, clypeus largely smooth, with strong luster (Fig. 4E, F View Figure 4 ). Clypeus elevated, anterior margin narrowly and roundly incised; labrum small and triangular; malar space 1.7 × diameter of middle ocellus (Fig. 4E View Figure 4 ); postocellar area 2.0 × broader than long, middle furrow weak; lateral furrows distinct, slightly divergent backwards; POL: OOL: OCL = 3: 4: 6; eyes behind head distinctly enlarged (Fig. 4F View Figure 4 ). Antenna 1.6 × head breadth, club broad and long, with widest breadth 2.2 × apical breadth of antennomere 3, about 1.1 × as long as antennomere 3, antennomere 3 as long as longest axis of eye.
Thorax. Punctures on mesoscutal middle and lateral lobes small and dense, surface weakly microsculptured; scutellum roundly elevated without middle furrow, punctures minute and sparse, top area smooth; distance between inner margin of cenchri 2.1 × longest axis of a cenchrus (Fig. 4G View Figure 4 ); mesopleuron with a sharp oblique carina, punctures above carina dense and small, interspaces between punctures distinctly microsculptures (Fig. 4H View Figure 4 ); punctures on area below carina sparser.
Abdomen. Abdominal tergum 1 with minute punctures and microsculptured, other terga finely and densely microsculptured. Tergum 1 with obtuse and roundly curved lateral carina, posterior incision broad and not very deep, bottom round, middle depth about half the length of tergum (Fig. 4A View Figure 4 ); middle process of sternum 7 broad and triangular, basal breadth about 1/3 breadth of sternite 7; apical margin of ovipositor sheath obliquely truncate in lateral view, lower margin round (Fig. 4L View Figure 4 ); lance long and slender, subapical annuli not broadened, total length of annuli 5 × height of 13th annulus, first annulus 2.1 × as high as broad (Fig. 4J View Figure 4 ); lancet with 48 serrulae (Fig. 4K View Figure 4 ), middle serrulae weakly narrowed toward truncate apex, each side with 3-4 large subbasal teeth, distance between middle serrulae 1.5 × basal breadth of serrulae (Fig. 4M View Figure 4 ).
