Measurement. Male, 3.35–3.45 mm (including wings).
Description. Body mostly dark brown ( Figs 29, 30 View FIGURES 17–32 ). Face mostly brown, frontoclypeal area with dark brown transverse stripes, lorum brown, genae largely blackish brown ( Fig. 32 View FIGURES 17–32 ). 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 View FIGURES 17–32 ). 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 View FIGURES 49–60 ).
Abdominal apodemes extending to base of 6th abdominal sternite ( Fig. 114 View FIGURES 114–120 ). 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 View FIGURES 114–120 ). Subgenital plate with distal part bearing some long fine setae and small rigid setae; a distinct protrusion subapically ( Figs 116, 117 View FIGURES 114–120 ). Style with a short horn-like subapical process forming an obtuse angle with apical part ( Figs 116, 118 View FIGURES 114–120 ). Connective without prominent central lobe ( Fig. 116 View FIGURES 114–120 ). 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 View FIGURES 114–120 ).

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 View FIGURES 114–120 ); robust lower branch on aedeagal shaft curved towards the left side of shaft ( Figs 119, 120 View FIGURES 114–120 ).
Etymology. This specific epithet is derived from Latin word “chela”, referring to the bifurcate pygofer process with a common robust stem ( Fig. 115 View FIGURES 114–120 ).
