Figs. 4–5 , 13–15

Description. Male. ( Fig. 4 ) Body small-sized and pubescent. Head slightly narrower than anterior margin of pronotum; frontal rostrum rather obvious and about 1.4 times as wide as scapus; eyes large and protruding forwards; 3rd-5th joints of maxillary palpi distinctly elongate, 5th joint straight at apex. Pronotum transverse, strongly widened posteriorly, about 1.8 times as long as width of posterior margin, anterior and posterior margins straight. Tegmina extending slightly over apex of abdomen, present with one oblique vein, mirror slightly elongate, about 1.2 times as long as wide; wings absent. Fore tibia with a large and oblong external tympanum, about 2.3 times as long as wide; internal tympanum absent. Hind tibia with two internal apical spurs longer outer ones.

Supra anal plate narrowed posteriorly, posterior margin narrow and round; dorsal area with a transverse impression in centre. Subgenital plate slightly transverse, slightly narrowed posteriorly, posterior margin almost straight with a small protuberance in middle. Genitalia ( Figs. 13–15 ): lateral lobe of epiphallus shorter than medial lobe, not narrowed apically in dorsal view, with upper margin protuberant in middle, and the protuberance serrated at apex; endophallus apodeme long.

Female. ( Fig. 5 ) Pronotum slightly widened posteriorly. Tegmen rather convex, not extending to apex of abdomen, present with 5 regular veins on dorsal field; lateral field with 4 oblique subcostal veins. Ovipositor short, slightly shorter than half of hind femur.

Coloration. Body yellow, without stripes. Eyes dark. Apex of hind femur with a small dark spot on outer side.

Measurements (mm). Male: body 5.3–5.5, pronotum 0.9–1.0, tegmen 3.9–4.0, hind femur 4.5–4.6; female: body 5.5, pronotum 0.9, tegmen 2.5, hind femur 4.6, ovipositor, 2.1.

Type material. Holotype ♂, CHINA, Yunnan, Mengla, Menglun, 30.VII.2006, leg. Hao-yu Liu. Paratypes: 1♂ 1♀, CHINA, Yunnan, Mengla, Shangyong, 2.VIII.2007, leg. Fu-ming Shi & Shao-li Mao.

Distribution. China (Yunnan).

Diagnosis. This new species is related to A. brevisparamerus sp. nov., but can be distinguished on the structure of the lateral lobe of the epiphallus with its upper margin protuberant in middle, and the protuberance serrated at apex; dorsal area of head and pronotum without longitudinal stripes.

Etymology. This new specific name is derived from Latin serratus (serrate) + protuber (protruding), a reference to lateral lobe of epiphallus rather short.
