Diagnosis. The new species is characterized by narrowly falcate forewing with distinct pterostigma which is reddish-brown in middle, narrowly subquadrate male tergum 9 + ectoprocts, male gonocoxites 9 feebly protruding distally, and male fused gonocoxites 11 (= gonarcus) rod-shaped at base.

Description. Male. Forewing length 8.01 mm, hindwing length 7.30 mm.

Head yellow. Compound eyes blackish brown. Antennae yellow with yellowish setae, the distal quarter of the antennal flagellomeres gradually darkened; scape long and thick, as long as proximal four flagellomeres.

Thorax yellow; pronotum pale brown, with blackish brown spots laterally; meso- and metanotum brown. Legs yellow, tibiae with dark brown spots ventrally. Forewing with narrowly falcate apex, slightly pale brown, with dark brown markings on branching points of most longitudinal veins; pterostigma distinct, reddish-brown in middle. Longitudinal veins pale yellow, interrupted by many brownish spots; crossveins brown. Hindwing much paler than forewing, with brown markings on branching points of some longitudinal veins. Longitudinal veins pale yellow, crossveins brown.

Abdomen brown.

Tergum 9 + ectoprocts in lateral view narrowly subquadrate, strongly tapering posteroventrally into digitiform process, which bears tuft of spinous setae ( Figs 3B View Fig , 4A View Fig ). Trichobothria reduced. Sternum 9 shorter than sternum 8, slightly concaved posteriad in ventral view ( Figs 3C View Fig , 4B View Fig ). Gonocoxites 9 in lateral view rod-shaped in basal half and expanded as subtriangular plate in distal half, covered densely with short setae, posteriorly slightly protruding; in ventral view distal plate slenderly narrowed, distally with tiny, pointed apex ( Figs 3 View Fig , 4 View Fig ). Complex of fused gonocoxites, gonapophyses and gonostyli 10 with basal sclerite, which extends laterally and posteriorly in middle in ventral view, has pair of broad ovoid lobes laterally, and short bow formed by bundled bristles that extends anteriorly to segment 8 ( Figs 3 View Fig , 4 View Fig ). Fused gonocoxites 11 (= gonarcus) arched, rod-like at base, in lateral view posteriorly slightly expanded as broad semilunar plate ( Figs 3 View Fig , 4 View Fig ). Hypandrium internum subtriangular ( Figs 3 View Fig , 4 View Fig ). Differential diagnosis. See Differential diagnosis under A. christophi U. Aspöck & H. Aspöck , sp. nov.
