Diagnosis.

This species can be easily separated from other Chinese Anaplecta species by its hook-shaped L2vm and R1.

Etymology.

The specific epithet is derived from the Latin word hamatus, referring to both L2vm and R1 being hook-like.

Description.

Measurements (mm). Male: Pronotum length × width: 1.2-1.4 × 1.9-2.0, tegmina length: 5.8-6.4, overall length: 6.8-7.3. Female: Pronotum length × width: 1.1-1.4 × 1.9-2.2, tegmina length: 5.4-5.6, overall length: 6.2-6.7.

Coloration. Body yellowish brown, eyes black, antennae dark brown. Head yellowish brown (Fig. 3A, B, C ). Pronotum and tegmina yellowish brown, lateral borders nearly hyaline (Fig. 3D, E ). Wings with costal field and appendicular field infuscated, other parts light brown, with veins dark brown (Fig. 3E, H ). Abdominal sterna, cerci and legs yellowish brown (Fig. 3B ).

Head and thorax. Interocular space slightly greater than distance between antennal sockets. Fourth and fifth maxillary palpi equal in length, shorter than third maxillary palpus; fifth maxillary palpus triangular and thicker than others (Fig. 3C ). Pronotum subelliptical (Fig. 3D ). Tegmina with indistinct veins; wings with radial veins slightly indistinct, CuP and CuA merging into one venation (Fig. 3E, H ). Front femur type B2 (Fig. 3G ), pulvilli absent, tarsal claws symmetrical, arolia present.

Male abdomen and genitalia. Supra-anal plate symmetrical, sheet-like (Fig. 3F ). Subgenital plate subelliptical, with an anterior extension in the left and the posterior margin slightly arched (Fig. 3I ). Styli small, cylindrical, styli with length about ⅓ of interstylar space (Fig. 3I ). Phallomere complex, L1 small, with slender and curved filamentary structure. L2v elongated, bifurcated at apex and highly sclerotized at terminal. L2vm broad with curved hook at the left (Fig. 3K ). L3 robust and medium, uncinate part with apex blunt (Fig. 3J ). R1 hooked, the proximal part sharply tapered and highly sclerotized (Fig. 3L ). R2 irregular, slightly sclerotized. R3 short, simple sheet-like (Fig. 3M ).

Female abdomen and genitalia. Supra-anal plate nearly symmetrical. Paraprocts (pp.) broad, extending to the posterior margin of supra-anal plate. Intercalary sclerite (intc.s) short, 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.) slightly sclerotized, with a near spine-shaped protrusion and dense tiny punctuations. Basivalvula (bsv.) nearly flat (Fig. 4D, E ). Laterosternal shelf (ltst.sh) slightly sclerotized lateral margin straight (Fig. 4F ).

Distribution.

China (Hunan, Fujian, Guangdong).
