Measurement. Male, 3.35–3.45 mm (including wings).
Description. Body mostly dark brown (Figs 29, 30). Face mostly brown, frontoclypeal area with dark brown transverse stripes, lorum brown, genae largely blackish brown (Fig. 32). Vertex yellowish-brown medially with a brown patch along anterior margin connecting the 2 lateral black patches. Pronotum largely brown, with one blackish brown patch near anterior margin medially and at each anterolateral angle; triangles dark brown, scutellum light yellow (Fig. 31). Forewing with some brown bands in basal 2/3, 2nd and 3rd apical cells smoky brown; brochosome area yellowish-brown with a blackish brown patch at each end (Fig. 56).
Abdominal apodemes extending to base of 6th abdominal sternite (Fig. 114). Male pygofer with an annulate setal group near posterior margin, several small rigid setae along protruded posterodorsal margin; a bifurcate pygofer process with a common robust stem on middle of posterior margin (Fig. 115). Subgenital plate with distal part bearing some long fine setae and small rigid setae; a distinct protrusion subapically (Figs 116, 117). Style with a short horn-like subapical process forming an obtuse angle with apical part (Figs 116, 118). Connective without prominent central lobe (Fig. 116). Aedeagal shaft with a plate-like ventral expansion apically, a dorsal plate-like expansion subapically, with a bifurcate ventral process at middle, upper branch small and directed towards shaft apex, robust lower branch curved towards the left side of shaft (Figs 119, 120).
Specimens examined. Holotype: ♂, CHINA, Yunnan Province, Dali City, Mt. Cangshan, 2300m, 22 Jun 2022, coll. Junjie Wang and Zhou Xian. Paratype: 4♂ 2♀, same data as holotype; 2♂, CHINA, Yunnan Province, Gongshan Derung and Nu Autonomous County, Shuanglawa Village, 1800m, 17 Jun 2019, coll. Lü Lin; 2♂ 1♀, CHINA, Yunnan Province, Ailaoshan National Nature Reserve, 2200m, 6 Jun 2022, coll. Junjie Wang; 2♂ 1♀, CHINA, Yunnan Province, Gaoligongshan National Nature Reserve, 1650m, 16 Jun 2022, coll. Junjie Wang; 1♂ 1♀, CHINA, Yunnan Province, Lijiang City, Xinzhu Village, 2360m, 3 Jul 2022, coll. Junjie Wang; 1♂, CHINA, Yunnan Province, Huanglianshan National Nature Reserve, 1650m, 10 Jun 2023, coll. Lü Lin.
Remarks. The new species is similar to A. (D.) rita, but differs in the following characteristics: pygofer process arising from the middle of posterior margin, and bifurcated into upper and lower branches (Fig. 115); robust lower branch on aedeagal shaft curved towards the left side of shaft (Figs 119, 120).
Etymology. This specific epithet is derived from Latin word “chela”, referring to the bifurcate pygofer process with a common robust stem (Fig. 115).
