Type material.

Holotype: China • male; Hainan Prov., Qiongzhong County, Mt. Limu; 19°10.57'N, 109°43.77'E; 650 m; 20 June 2020; Yong Li, Jing Zhu, leg.; SWU-B-B-A060012.

Paratypes: China • 1 male and 1 female; same data as holotype; SWU-B-B-A060013 and 060014.

Diagnosis.

This species is slightly similar to A. anncajanoae Lucañas, 2016, but can be distinguished from the latter by the spines on the left phallomere. It is also similar to A. cruciata Deng & Che, 2020 in body color and size, but can be distinguished as follows: 1) sclerites of the left phallomere spinous in A. spinosa sp. nov., while spineless in A. cruciata ; 2) one of R2 with dense punctuations in A. spinosa sp. nov., while A. cruciata without; 3) anterior margin of anterior arch with a long horn-shaped protrusion in A. spinosa sp. nov., that of A. cruciata blunter and rounder; and 4) basivalvula nearly triangular in A. spinosa sp. nov., while nearly rectangular in A. cruciata .

Etymology.

The specific epithet is derived from the Latin word spinosus, referring to the left phallomere that is spiny.

Measurements (mm).

Male: pronotum length × width: 1.19-1.38 × 1.80-1.89, tegmina length: 4.12-4.28, overall length: 5.10-5.57. Female: pronotum length × width: 1.30 × 1.92, tegmina length: 4.29, overall length: 5.55.

Description.

Coloration. Body dark brown, face dark brown, terminal of clypeus and labrum yellowish brown (Fig. 4A, B ). Antennae brown, maxillary palpus pale brown (Fig. 4D ). Pronotum and tegmina dark brown, lateral edges hyaline (Fig. 4C, E ). Hind wings infuscate, costal field and appendicular field darker than remaining parts (Fig. 4F ). Center of abdominal sterna yellow, gradually darkening to dark brown to edges. Legs and cerci yellowish brown (Fig. 4B ).

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. 4D ). Pronotum nearly sub-parabolic, anterior and posterior margins straight (Fig. 4C ). Tegmina with slightly indistinct veins; radius posterior veins of hind wings slightly indistinct, with one discontinuous or no transverse veins between M and CuA (Fig. 4E, F ). Front femur Type B2. Pulvilli absent, tarsal claws symmetrical.

Male genitalia. Supra-anal plate symmetrical. Both paraprocts extend into a strip, with spines on posterior margins (Fig. 4G ). Subgenital plate sub-trapezoidal, the center of anterior and interstylar margins straight. Styli medium, length ~ 1/4 of interstylar space (Fig. 4H ). L1 fan-shaped, with a curved and long filamentary structure. Terminal of L2v needle-like. L2d small. L2vm with brush-like structure and tapering at terminal. L3 robust, hook-like, apical part enlarged and slightly sharp (Fig. 4I ). R2 irregular, weakly sclerotized; one of R2 with dense punctuations. R3 slightly curved, sheet-like (Fig. 4J ).

Female genitalia. Supra-anal plate nearly symmetrical. Paraprocts broad, not extending to the posterior margin of supra-anal plate. Intercalary sclerite strip-shaped, slightly curved. First valve robust, with inward protrusions. Second valve small, basally fused. Third valve broad. The anterior margin of anterior arch slightly sclerotized, with a long horn-shaped protrusion, lateral area with dense tiny punctuations (Fig. 13D, E ). Basivalvula broad, the right lateral deeply concave, lateral area with dense punctuations (Fig. 13D ). Spermatheca slightly sclerotized at base. Laterosternal shelf slightly sclerotized, lateral margin slightly curved, with dense spinules at base (Fig. 13F ).

Distribution.

China (Hainan).
