Type material.

Holotype: China • male; Yunnan Prov., Pu’er County, Xiniuping Scenic Area of Pu’er National Park; 26°36.14'N, 101°5.53'E; 1602 m; 29 Jun. 2021; Jia-Wei Zhang & Jin-Lin Liu leg; SWU-B-AN-0175. Paratypes: China • 9 males & 14 females; same data as holotype; SWU-B-AN-0176 to 0198.

Diagnosis. This species can be easily separated from other Chinese Anaplecta species by its curled left phallomere (L2vm).

Etymology.

The specific epithet ' circinalis ' is derived from the Latin word circinalis, referring to the curled L2vm.

Description.

Measurements (mm). Male: Pronotum length × width: 1.0-1.3 × 1.8-1.9, tegmina length: 5.0-5.2, overall length: 5.8-6.1. Female: Pronotum length × width: 1.2-1.4 × 1.7-2.0, tegmina length: 4.7-5.1, overall length: 5.6-6.2.

Coloration. Body dark yellowish brown, eyes black, antennae dark brown. Head yellowish brown (Fig. 2A, B, D ). Pronotum dark yellowish brown, lateral borders nearly hyaline (Fig. 2C ). Tegmina yellowish brown, lateral borders nearly hyaline (Fig. 2E ). Wings with costal field and appendicular field light brown, other parts light brown, veins dark brown (Fig. 2H ). Center of abdominal sterna yellowish brown, gradually darkening to edges. Cerci and legs yellowish brown.

Head and thorax. Interocular space slightly greater than distance between antennal sockets. Third and fifth maxillary palpi equal in length, longer than fourth; fifth maxillary palpus subelliptical and thicker than other segments (Fig. 2D ). Pronotum subelliptical, anterior margin arched, hind margin nearly straight (Fig. 2C ).

Tegmina with indistinct veins; the radius posterior veins of hind wings slightly indistinct, CuP and CuA merging into one venation (Fig. 2E, H ). Front femur type B2 (Fig. 2G ), pulvilli absent, tarsal claws symmetrical, arolia present.

Male abdomen and genitalia. Supra-anal plate nearly symmetrical, sheet-like (Fig. 2F ). Subgenital plate asymmetrical, interstylar margin arched, with a pair of anterior extensions (Fig. 2I ). The left styli more robust than the right. Styli with length about 1/3 of interstylar space (Fig. 2I ). Phallomere complex, L1 small, with slender and curved filamentary structure. L2v elongated, slightly bifurcated. L2vm broad, slightly thickened and curved. L2d slender and bifurcated. L3 slender, uncinate part blunt (Fig. 2J ). R1 absent. R2 irregular, sheet-like, slightly sclerotized. R3 simple, sheet-like (Fig. 2K ).

Female abdomen and genitalia. Supra-anal plate nearly symmetrical. Paraprocts (pp.) broad, not extending to the posterior margin of supra-anal plate. Intercalary sclerite (intc.s) nearly stripe-shaped, slightly curved. First valvifer arm short. First valve (v.I) robust. Second valve (v.II) small, basally fused. Third valve (v.III) broad. The anterior margin of anterior arch (aa.) symmetrical, slightly sclerotized, extending forward in a flaky shape with a deep concavity in the middle. Basivalvula (bsv.) nearly flattened, elliptical (Fig. 4A, B ). Laterosternal shelf (ltst.sh) slightly sclerotized, lateral margin straight (Fig. 4C ).

Distribution.

China (Yunnan).
