Figures 7, 14D-F

Type material.

Holotype: China • male; Yunnan Prov., Pu’er City, Mt. Wuliang; 24°38'N, 100°44'E; 1232 m; 21 July 2020; Li-Kang Niu, Rong Chen, leg.; SWU-B-B-A060056.

Paratypes: China • 11 males and 5 females; same data as holotype; SWU-B-B-A060057 to 060072.

Diagnosis.

This species is slightly similar to A. falcifer Hebard, 1925 but differs in the coloration of pronotum and tegmina. It is also similar to A. strigata Deng & Che, 2020 in body color and pronotum, but can be distinguished as follows: 1) the base of the tegmina almost black, while A. strigata mostly uniform dark yellowish brown; 2) L2d nearly rectangular in A. anomala sp. nov., while slightly bent in A. strigata; and 3) anterior margin of anterior arch with a finger-like protrusion, while the protrusion of A. strigata nearly wavy.

Etymology.

The specific epithet is derived from the Latin word anomalus, referring to the left phallomere being different from other species.

Measurements (mm).

Male: pronotum length × width: 1.20-1.42 × 1.68-1.95, tegmina length: 4.52-5.49, overall length: 5.94-6.54. Female: pronotum length × width: 1.29 × 1.97, tegmina length: 4.67-5.13, overall length: 5.91-6.22.

Description.

Coloration. Body dark brown, face brown, terminal of clypeus and labrum yellowish brown (Fig. 7A, B). Antennae and maxillary palpus brown (Fig. 7D). Pronotum dark brown, middle part lighter, lateral edges nearly hyaline (Fig. 7C). Tegmina dark brown, lateral edges nearly hyaline, 1/3 of the base darker than remaining parts (except for anal field) (Fig. 7E). Hind wings infuscate, costal field and appendicular field darker than remaining parts (Fig. 7F). Abdominal sterna, legs, and cerci pale yellowish brown (Fig. 7B).

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. 7D). Pronotum sub-elliptical, anterior and posterior margins nearly straight (Fig. 7C). Tegmina with slightly indistinct veins; radius posterior veins of hind wings slightly indistinct, without transverse veins between M and CuA (Fig. 7E, F). Front femur Type B2 (Fig. 7B). Pulvilli absent, tarsal claws symmetrical.

Male genitalia. Paraprocts bifurcated at the base: the upper part strip-shaped, length ~ 1/2 of paraprocts, the rest sheet-like (Fig. 7G). Subgenital plate slightly asymmetrical, the left margin slightly wider than the right, the interstylar margin extremely convex. Styli short, the distance between them long (Fig. 7H). L1 fan-shaped, with a curved and long filamentary structure. L2v handle-shaped, with a sharp horn. L2d an approximate rectangle. L2vm with a curled and thickened sclerite, crescent-like with dense spines. L3 medium, hook-like, apical part enlarged and slightly sharp (Fig. 7I). R2 irregular, weakly sclerotized, one of R2 sheet-like, with sharp apex. R3 slightly curved, sheet-like (Fig. 7J).

Female genitalia. Supra-anal plate nearly symmetrical. Paraprocts broad, not extending to the posterior margin of supra-anal plate. Intercalary sclerite slender. First valve tubular. Second valve small, basally fused. Third valve broad. The anterior margin of anterior arch slightly sclerotized, with a finger-like protrusion. Basivalvula broad, nearly triangle, anterior and posterior margin slightly curled (Fig. 14D, E). Vestibular sclerite sheet-like. Laterosternal shelf slightly sclerotized, lateral margin nearly straight (Fig. 14F).
