Material examined.

Holotype. China: Male, Guangxi, Jingxi, Longbang , 22.87°N, 106.32°E, 1.V.2019, Libin Ma & Tao Zhang leg. Paratypes. 10 males and 2 females, same information as holotype (SNNU).

Description.

Male (Figs 3C , 5A ). Body size small. Head small and pubescent, slightly wider than anterior margin of pronotum; frontal rostrum 1.2 times wider than antennal scape; eyes large and protruding forwards; apical three joints of maxillary palpi distinctly elongate, 5th joint truncated apically. Pronotum transverse, strongly widened posteriorly, and slightly wider than the anterior. Tegmina extending slightly over apex of abdomen, armed with one oblique vein; mirror slightly elongate; hindwings absent. Fore tibia armed with a large long-oval external tympanum; internal tympanum absent. Hind tibia bearing three dorsal spurs on two sides respectively, and bearing two apical spurs inside and three outside.

Genitalia (Fig. 4D-F ). Lateral lobes of epiphallus slightly longer than median lobes in lateral view and possessing horned protuberances at inner margin proximally and outer margin medially, bearing several teeth at inner and outer margin and not narrowed apically in lateral view. Ectoparameres short and serrated apically.

Female (Figs 3D , 5B ). Body slightly smaller than male. Tegmen rather convex, armed with five regular veins on dorsal field. Ovipositor blade-shaped.

Coloration.

Body colored yellow. Dorsal area of head ornamented with four brown longitudinal stripes. Apex of each hind femur bearing a small dark spot in two sides respectively. Ovipositor ventrally colored brown to dark brown and remainder yellowish.

Measurements.

Male. BL 4.92-6.05, PL 0.94-1.15, TL 3.42-4.09, HFL 3.56-4.17. Female. BL 4.65-4.94, PL 0.87-0.90, TL 3.21-3.33, OL 1.892.03.

Etymology.

The name refers to the epiphallic median lobes almost as long as the lateral lobes.

Distribution.

China (Guangxi) (Fig. 1 ).

Remarks.

This species is very similar to A. serratiprotuberus and A. longiserratus in dorsal and ventral views of the male genitalia, but different in lateral view (epiphallic lateral lobes of the new species possessing horned protuberances at the inner margin proximally and the outer margin medially, and the ectoparameres of this new species are acute apically).
