Measurements (mm).

Male: pronotum length × width: 1.39-1.53 × 1.94-2.03, tegmina length: 5.17-5.76, overall length: 6.57-7.09. Female: pronotum length × width: 1.42 × 1.92, tegmina length: 5.12, overall length: 6.43.

Diagnosis.

This species is similar to A. omei Bey-Bienko, 1958, but can be distinguished as follows: 1) right paraproct long hooked in A. longihamata sp. nov., while sheet-like in A. omei ; 2) R1 bifurcated in A. omei , while unbranched in A. longihamata sp. nov.;3) anterior arch with two transversely finger-like protrusions in A. longihamata sp. nov., while A. omei without; and 4) first valvifer arm lateral edges folded up in A. longihamata sp. nov., while not folded in A. omei .

Etymology.

The specific epithet is derived from the Latin words longi and hamatus, referring to the right paraproct extended backward in a long hook shape.

Description.

Coloration. Body yellowish brown, face yellowish brown (Fig. 10A, B ). Antennae and maxillary palpus brown (Fig. 10D ). Pronotum yellowish brown, lateral edges hyaline (Fig. 10C ). Tegmina light yellowish brown, lateral edges pale (Fig. 10E ). Hind wings infuscate, costal field and appendicular field darker than remaining parts (Fig. 10F ). Abdominal sterna, legs, and cerci yellowish brown (Fig. 10B ).

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. 10D ). Pronotum subelliptic, anterior and posterior margins nearly straight (Fig. 10C ). Tegmina with slightly indistinct veins; radius posterior veins of hind wings slightly indistinct, without transverse veins between M and CuA (Fig. 10E, F ). Front femur Type B2 (Fig. 10B ). Pulvilli absent, tarsal claws symmetrical.

Male genitalia. Supra-anal asymmetrical, the left paraproct sheet-like, right paraproct extending backward, hooked, and curled at apex with dense spines (Fig. 10G ). Subgenital plate sub-rectangular, the center of anterior and interstylar margins nearly straight. Styli long, length about 1/4 of interstylar space (Fig. 10H ). L1 subelliptic, thickened at anterior edge, with a curved and long filamentary structure connected. L2v curved, bifurcated at the apex, with a sharp horn. L2vm sheet-like. L3 extremely robust, with long uncinate part and bent at right angles (Fig. 10I ). R1 needle-shaped, the proximal part slightly curved (Fig. 10J ). R2 irregular, weakly sclerotized, one of R2 with small protrusions. R3 broad, sheet-like (Fig. 10K ).

Female genitalia. Supra-anal plate nearly symmetrical. Paraprocts broad, extending to the posterior margin of supra-anal plate. Intercalary sclerite short, sheet-like. Right first valvifer arm extremely robust, lateral edges folded up, fused with crosspiece (Fig. 16A ). First valve robust. Second valve small, basally fused. Third valve broad. The anterior margin of anterior arch slightly sclerotized, with a hook-shaped protrusion, hind edge with two transversely finger-like protrusions. Basivalvula irregular, anterior edge curly. Vestibular sclerite sheet-like (Fig. 16A, B ). Laterosternal shelf slightly sclerotized, lateral margin nearly straight (Fig. 16C ).

Distribution.

China (Yunnan).
