Type material.

Holotype: China • male; Yunnan Prov., Xishuangbanna, Shangyong Town; 21°16.80'N, 101°31.80'E; 870 m; 7 July 2020; Du-Ting Jin, Rong Chen leg.; SWU-B-B-A060015.

Paratypes: China • 4 males and 2 females; same data as holotype; SWU-B-B-A060016 to 060021 • 1 male; Yunnan Prov., Jinghong City, Nabanhe Nature Reserve; 22°14.08'N, 100°36.29'E; 1080 m; 3 July 2020; Du-Ting Jin, Yi-Shu Wang, leg.; SWU-B-B-A060022.

Diagnosis.

This species is similar to A. cruciata Deng & Che, 2020 in body color and size, but can be distinguished as follows: 1) R2 serrated in A. serrata sp. nov., while that of A. cruciata without serration; 2) anterior margin of anterior arch with a sheet-like protrusion in A. serrata sp. nov.; while the protrusions of A. cruciata nearly Y-shaped; and 3) basivalvula extremely curled in A. serrata sp. nov., while slightly in A. cruciata .

Etymology.

The specific epithet is derived from the Latin word serratus, in reference to the serrated lateral edges of R2.

Measurements (mm).

Male: pronotum length × width: 1.12-1.25 × 1.67-1.85, tegmina length: 3.93-4.46, overall length: 5.06-5.53. Female: pronotum length × width: 1.07-1.19 × 1.67-1.69, tegmina length: 4.02-4.06, overall length: 5.00-5.09.

Description.

Coloration. Body dark brown, face dark brown, terminal of clypeus and labrum yellowish brown (Fig. 5A, B ). Antennae and maxillary palpus brown (Fig. 5D ). Pronotum and tegmina dark brown, lateral edges nearly hyaline (Fig. 5C, E ). Hind wings infuscate, costal field and appendicular field darker than remaining parts (Fig. 5F ). Center of abdominal sterna yellow, gradually darkening to dark brown to edges. Legs and cerci pale yellowish brown (Fig. 5B ).

Head and thorax. The distance between antennal sockets slightly narrower than interocular space. Fifth maxillary palpus nearly triangular, slightly thicker and wider than others (Fig. 5D ). Pronotum sub-elliptical, anterior margin straight, posterior margin arcuate (Fig. 5C ). Tegmina with slightly indistinct veins, radius posterior veins of hind wings slightly indistinct, with one transverse veins between M and CuA (Fig. 5E,F ). Front femur Type B2 (Fig. 5B ). Pulvilli absent, tarsal claws symmetrical.

Male genitalia. Paraprocts bifurcated at the base: filamentary part short, another part sheet-like (Fig. 5E ). Subgenital plate almost symmetrical, anterior margin concave, interstylar margin convex. Styli short, the distance between them long (Fig. 5H ). L1 narrow, with a curved and long filamentary structure; L2v broad, folded in the middle. L2d elongated with a sharp horn. L3 small, uncinate part extremely bent (Fig. 5I ). R2 irregular, weakly sclerotized; one of R2 with sharp apex, another serrated. R3 slightly curved, sheet-like (Fig. 5J ).

Female genitalia. Supra-anal plate nearly symmetrical. Paraprocts broad, not extending to the posterior margin of supra-anal plate. Intercalary sclerite strip-shaped. First valve long. Second valve small, basally fused. Third valve broad. The anterior margin of anterior arch slightly sclerotized, extending forward into a sheet-like protrusion, with wavy depressions. Basivalvula broad, extremely curled, with dense punctuations (Fig. 13G, H ). Laterosternal shelf slightly sclerotized, lateral margin slightly curved (Fig. 13I ).

Distribution.

China (Yunnan).
