This species is quite similar to <i>A. eous</i> (Semenov, 1935) and <i>A. maculotegularis</i> Yan &amp; 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. <b>Holotype, female.</b> Body length 21 mm (Fig. 4A). <b> <i>Color</i>.</b> Head dark yellowish brown, frontal area with a M-shaped narrow black maculae, clypeus and mouthparts largely yellowish brown (Fig. 4E), antenna reddish brown (Fig. 4D); 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); 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), 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), 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. <b> <i>Head</i>.</b> Dorsum of head with indistinct and minute punctures, clypeus largely smooth, with strong luster (Fig. 4E, F).
