(Figs 51–60, 116–118)

Type materials. China: holotype ♂, Sichuan Prov., Mianning, 8.vi.1999, coll. I. Dworakowska; paratypes: 4♂♂, Sichuan Prov., Mianning, 8.vi.1999, coll. Daozheng Qin. All in NWAFU.

Length: ♂ 3.2 mm–3.4 mm.

Ground colour of body yellowish (Fig. 118). Crown with light green patch on each side of coronal suture (Fig. 116). Eyes brown. Pronotum with irregular patches on anterior margin of pronotum and under eyes. Forewing and hind wing semitransparent. Abdomen light yellow. Legs light green to yellow-greenish (Fig. 117).

Ventral abdominal apodemes well developed, reaching midlength of segment 5, parallel-sided to broadly rounded apices (Fig. 58). Male pygofer slightly narrowing caudad, with a few rigid setae on caudal-dorsal angle (Fig. 51); ventral pygofer appendage tapering, slightly curved, not exceeding lobe margin (Fig. 52). Anal appendage solid, with numerous serrations apically (Fig. 53). Subgenital plate in lateral view, curved gradually caudodorsad apically, tapering to rounded apex; with numerous macrosetae and fine setae somewhat irregularly scattered; dorsolateral margin group A with 5 long stout setae, group B with 24–26 short microsetae on apical 2/3 (Fig. 60), group C double near base, with a single row of macrosetae distally, group D irregular with numerous elongate setae. Paramere with 6–7 teeth on dentifer, several setae subapically (Fig. 59). Connective broad, with anterior margin slightly emarginated medially (Fig. 54). Aedeagus with preatrium straight, longer than shaft; dorsal apodeme well developed; shaft in lateral view curved dorsad, with ventral notch adjacent to gonopore, without dorsal denticuli; apical process elongate, slender, strongly curved, apex tapered and serrate (Figs 55, 56).

Etymology. The specific epithet is derived from the Latin " reflexus " meaning "turned back" and refers to the reflexed aedeagal process.

Diagnosis. The new species is similar to A. kaicola Dworakowska, 1982, but can be distinguished by the strongly curved aedeagal appendage lacking an apical bifurcation.
