Type material.

Holotype: China • male; Guizhou Prov., Dushan County; 25°45.60'N, 107°33.03'E; 7 June 2019; Lu Qiu, Wen-Bo, Deng, leg.; SWU-B-B-A060104.

Paratypes: China • 12 males and 4 females, same data as holotype; SWU-B-B-A060105 and 060120.

Diagnosis.

This species is very similar to A. omei , but can be distinguished as follows: 1) the paraprocts not extending backward in A. paraomei sp. nov., while left paraproct extending backward in A. omei ; 2) the apex of R1 nearly symmetrical in A. paraomei , while asymmetrical in A. omei ; 3) intercalary sclerite nearly strip-shaped in A. paraomei , while spindle-shaped in A. omei ; and 4) posterior margin of anterior arch hip-shaped in A. paraomei sp. nov., while smooth in A. omei .

Etymology.

The Latin word para means similar, referring to its close resemblance to A. omei .

Measurements (mm).

Male: pronotum length × width: 1.29-1.35 × 2.00-2.09, tegmina length: 5.24-5.53, overall length: 6.15-6.57. Female: pronotum length × width: 1.44 × 2.09, tegmina length: 5.31, overall length: 6.23

Description.

Coloration. Body yellowish brown, face yellow (Fig. 11A, B ). Antennae and maxillary palpus brown (Fig. 11D ). Pronotum and tegmina yellowish brown, lateral edges hyaline (Fig. 11C, E ). Hind wings infuscate, costal field and appendicular field darker than remaining parts (Fig. 11F ). Abdominal sterna, legs, and cerci yellow brown (Fig. 11B ).

Head and thorax. The distance between antennal sockets narrower than interocular space. Fifth maxillary palpus nearly oval, slightly thicker and wider than others (Fig. 11D ). Pronotum subelliptic, anterior and posterior margins nearly straight, lateral margin protruding and arc-shaped (Fig. 11C ). Tegmina with slightly indistinct veins, radius posterior veins of hind wings slightly indistinct, with one transverse vein between M and CuA (Fig. 11E, F ). Front femur Type B2 (Fig. 11B ). Pulvilli absent, tarsal claws symmetrical.

Male genitalia. Supra-anal plate asymmetrical, the left paraproct with dense spines on curly posterior margin; right paraproct with dense spines on curly apex (Fig. 11G ). Subgenital plate sub-trapezoidal, the center of anterior slightly curved, interstylar margins straight. Styli medium, length about 1/5 of interstylar space (Fig. 11H ). L1 subcircular, with a curved and long filamentary structure. L2v curved, bifurcated at the apex, with a sharp horn. L2vm broad. L3 robust, with extremely bent and sharp uncinate part (Fig. 11I ). R1 highly sclerotized, the proximal part nearly dichotomous branching (Fig. 11J ). R2 irregular, weakly sclerotized. R3 slightly curved, sheet-like (Fig. 11K ).

Female genitalia. Supra-anal plate nearly symmetrical. Paraprocts broad, not extending to the posterior margin of supra-anal plate. Intercalary sclerite short, nearly strip-shaped (Fig. 16D, E ). Right first valvifer arm robust, curled (Fig. 16D ). First valve robust. Second valve small, basally fused. Third valve broad. The anterior margin of anterior arch slightly curled, with a nearly transparent hook-shaped protrusion and the posterior margin hip-shaped. Basivalvula broad, with dense punctuations, the right lateral deeply concave (Fig. 16D ). Vestibular sclerite broad, slightly curled, sheet-like. Laterosternal shelf slightly sclerotized, lateral margin nearly straight. (Fig. 16F ).

Distribution.

China (Guizhou).
