Description. BL: 10.9–13.5 mm, FL: 4.7–5.1 mm.

Body ( Fig. 1 View FIGURES 1–3 ) dark brown; mouth parts, tarsus and apical margin of abdominal tergites reddish brown.

Head ( Figs 2, 3 View FIGURES 1–3 ) shorter than wide (HL/HW=0.85–0.87), slightly dilated behind eyes. Temples 1.66–1.77 times as long as eyes. Dorsal macrosetae (one side only): one near antennal base; one medially between eyes; one postero-medially, closer to neck constriction than to posterior margin of eye; one medially near neck constriction; two laterally on temple, of which one near posterior margin of eye, one near neck constriction. Surface with dense and fine non-setiferous punctation, lacking microsculpture. Antennae with segment 1 about as long as three following segments combined, segment 2 distinctly longer than segment 3, segments 4–8 longer than wide, becoming vaguely shorter, segment 9 about as long as wide, segment 10 slightly wider than long, last segment short, about as long as wide.

Pronotum ( Figs 2, 3 View FIGURES 1–3 ) shorter than wide (PL/PW=0.83–0.88), longer (PL/HL=1.33–1.41) and wider (PW/ HW=1.36–1.40) than head; with punctation slightly finer than those on head, lacking microsculpture. Dorsal macrosetae (one side only): One medial and two lateral.

Elytra ( Figs 2, 3 View FIGURES 1–3 ) with dense and coarse punctation and brown setae, lacking microsculpture, shorter than wide (EL/EW=0.79–0.84), slightly longer (EL/PL=1.00–1.05) and wider (EW/PW=1.06–1.10) than pronotum. Wings well developed. Scutellum with punctation and setae similar to those on elytra.

Abdomen ( Fig. 1 View FIGURES 1–3 ) with coarse punctation except for median part of tergite II; tergite VII with whitish apical seam; all tergites with dense and very fine transverse microsculpture.

Legs densely covered with brown setae, all tibiae with lateral spines.

Male. Sternite IX ( Fig. 4 View FIGURES 4–10 ) long and slender, with numerous long setae at apical portion; tergite X ( Fig. 5 View FIGURES 4–10 ) gradually narrowing apically, with several long setae situated at apical and lateral margins. Aedeagus ( Figs 6–9 View FIGURES 4–10 ): median lobe slightly constricted near middle, with wide apex in ventral view; paramere ( Figs 8, 9 View FIGURES 4–10 ) gradually narrowed apicad, distinctly shorter than median lobe, with bunch of three or four apical setae and numerous closely set sensory peg setae, forming a continuous transverse group.

Female. Tergite X ( Fig. 10 View FIGURES 4–10 ) with several long setae situated at apical and lateral margins.

Distribution. The species is known from Guangxi, southern China.

Remarks. The new species is very similar to A. shibatai Smetana, 1995 , but can be separated by the slightly truncate apex of median lobe of aedeagus in ventral view (in A. shibatai , with round apex), and by the sensory peg setae of paramere forming a continuous transverse group (in A. shibatai , forming two separate groups).

Etymology. The species is named in honor of Wen-Xuan Zhang, who collected some of the type specimens.
