Type material.

Holotype: China • male; Guizhou Prov., Libo County, Jiaou Village; 25°30.06'N, 107°67.02'E; 11 June 2019; Lu Qiu, Wen-Bo, Deng, leg.; SWU-B-B-A060121.

Paratypes: China • 3 males and 1 female; same data as holotype; SWU-B-B-A060122 to 060125 • 2 males; Guangxi Prov., Guiping City; 31 May-2 June 2014; Shun-Hua Gui, Xin-Ran Li, Jian-Yue Qiu, leg.; SWU-B-B-A060126 and 060127.

Diagnosis.

This species is very similar to A. omei , but can be distinguished as follows: 1) paraprocts both extending backward in A. condensa sp. nov., while only the left extending backward in A. omei ; 2) R1 needle-shaped in A. condensa sp. nov., while bifurcated in A. omei ; and 3) intercalary sclerite of A. condensa sp. nov. very small, filamentous, while that of A. omei is spindle-shaped.

Etymology.

The specific epithet is derived from the Latin word condensus, referring to the paraprocts with dense spines on curly posterior margin.

Measurements (mm).

Male: pronotum length × width: 1.36-1.39 × 1.78-1.84, tegmina length: 4.93-5.39, overall length: 5.92-6.59. Female: pronotum length × width: 1.29 × 1.73, tegmina length: 4.75, overall length: 5.82

Description.

Coloration. Body brown (some individuals from Guiping yellowish brown) (Fig. 2C, D ), face dark brown (Fig. 12A, B ). Antennae and maxillary palpus brown (Fig. 12D ). Pronotum dark brown, lateral edges nearly hyaline (Fig. 12C ). Tegmina yellowish brown, anal field and base of mediocubital field slightly darker (Fig. 12E ). Hind wings infuscate, costal field and appendicular field darker than remaining parts (Fig. 12F ). Center of abdominal sterna yellow, gradually darkening to dark brown to edges, legs, and cerci dark yellowish brown (Fig. 12B ).

Head and thorax. The distance between antennal sockets slightly narrower than interocular space. Fifth maxillary palpus nearly oval, slightly thicker and wider than others (Fig. 12D ). Pronotum semicircular, anterior margin arched, the center of posterior margin protrudes slightly (Fig. 12C ). Tegmina with indistinct veins, radius posterior veins of hind wings slightly indistinct, without transverse veins between M and CuA (Fig. 12E, F ). Front femur Type B2 (Fig. 12B ). Pulvilli absent, tarsal claws symmetrical.

Male genitalia. Paraprocts both extend backwards and with dense spines on curly posterior margin (Fig. 12G ). Subgenital plate sub-rectangular, the center of anterior and interstylar margins nearly straight. Styli long, so is the distance between them (Fig. 12H ). L1 subcircular, with curved and long filamentary structure. L2v curved, bifurcated, with a sharp horn. L2vm broad. L3 extremely robust, uncinate part blunt (Fig. 12I ). R1 needle-shaped, the proximal part slightly curved (Fig. 12J ). R2 irregular, weakly sclerotized. R3 slightly curved, sheet-like (Fig. 12K ).

Female genitalia. Supra-anal plate nearly symmetrical, very blunt and round. Paraprocts broad, hind margin blunt, not extending to the posterior margin of supra-anal plate. Intercalary sclerite small, nearly filamentous. First valve robust. Second valve small, basally fused. Third valve broad. The anterior margin of anterior arch slightly curled, with a hook-shaped protrusion (Fig. 16G-H ). Basivalvula broad, with dense punctuations, except for left lateral and anterior margin (Fig. 16G ). Vestibular sclerite broad, slightly curled, sheet-like. Laterosternal shelf slightly sclerotized, lateral margin straight (Fig. 16I ).

Distribution.

China (Guizhou, Guangxi).
