(Figs A–C, 1–7)

Description. Vertex brownish yellow, with two unconspicuous whitish preapical spots medially. Eyes black (Figs A, B). Face whitish yellow (Fig. C).

Male genitalia: Pygofer dorsal appendage slender, with many microspines apically ( Fig. 2 ). Subgenital plate with basolateral angulate projection prominent, with 3 macrosetae on lateral surface and numerous short stout setae from subbase to apex; apical 1/3, with dark color ( Fig. 3 ). Style apex with 3 short toothlike points; preapical lobe well developed ( Fig. 4 ). Aedeagus with pair of long slender subapical processes bowed laterad and curved ventrobasally; gonopore long, apical on ventral surface; preatrium slender, bent at right angle in lateral view, much longer than dorsal apodeme ( Figs 5, 6 ). Connective V-shaped, lateral arms long and stem short ( Fig. 7 ).

Measurement. Body length males 3.2–3.3 mm, females 3.3–3.4 (including wing).

Specimen examined. Holotype: ♂, CHINA, Henan Prov., Mt. Baiyun, 17-VIII-2008, coll. Yuehua Song and Can Li (GUGC). Paratypes: 9♂♂, 10♀♀ (GUGC), 3♂♂, 2♀♀ (GZNU), same data as holotype. Remarks. This species is similar to A. dziubka Sohi & Mann (1992) , but differs in having the aedeagus with just one pair of apical processes, arising from the two sides of the gonopore ( Figs 5, 6 ); the aedeagus preatrium much longer than the dorsal apodeme ( Fig. 5 ) and the pygofer dorsal appendage with many microspines at the apex ( Fig. 2 ).

Etymology. The specific name is derived from the Latin word “ cinctus ”, referring to the aedeagus with a pair of apical processes curved ventrobasally ( Figs 5, 6 ).
