Diagnosis.

This species can be easily separated from other species by its hoof-shaped right phallomere, and the vestibular sclerite with two serrated and curved long spines.

Etymology.

The specific epithet is derived from the Latin word ungulatus, referring to the apex of R2 shaped like a pig or horse hoof.

Measurements (mm).

Male: pronotum length × width: 1.40-1.47 × 1.95-2.00, tegmina length: 5.31-5.94, overall length: 6.77-7.23. Female: pronotum length × width: 1.21-1.44 × 1.97-2.03, tegmina length: 5.63-5.80, overall length: 6.62-7.11.

Description.

Coloration. Body yellowish brown, face yellowish brown (Fig. 6A, B ). Antennae brown, maxillary palpus pale brown (Fig. 6D ). Pronotum and tegmina yellowish brown, lateral edges nearly hyaline, tegmina with a slightly darker marking at the base of mediocubital field (Fig. 6C, E ). Hind wings infuscate, costal field and appendicular field darker than remaining parts (Fig. 6F ). Abdominal sterna, cerci, and legs yellowish brown (Fig. 6B ).

Head and thorax. The distance between antennal sockets slightly narrower than interocular space. Fifth maxillary palpus nearly triangular, slightly thicker and wider than others (Fig. 6D ). Pronotum sub-elliptical, anterior margin slightly curved and posterior margin straight (Fig. 6C ). Tegmina with slightly indistinct veins; the radius posterior veins of hind wings slightly indistinct, with one or two transverse veins between M and CuA (Fig. 6E, F ). Front femur Type B2. Pulvilli absent, tarsal claws symmetrical.

Male genitalia. Paraprocts bifurcated at the base: the upper part strip-shaped, approximately the length of paraprocts, the rest sheet-like (Fig. 6G ). Subgenital plate asymmetrical, the left margin longer and slender than the right, the interstylar margin curved. The length of styli ~ 1/4 of interstylar space (Fig. 6H ). L1 strip-shaped, with extremely curved and long filamentary structure. L2v with a right-angled bifurcation. L2d irregular. L2vm curls and thickens in a crescent shape, with dense spines. L3 slender, apical part extremely bent (Fig. 6I ). R2 irregular, weakly sclerotized; one of R2 diverging into two sharp horns at apex. R3 slightly curved, sheet-like (Fig. 6J ).

Female genitalia. Supra-anal plate nearly symmetrical. Paraprocts broad, extending to the posterior margin of supra-anal plate. Intercalary sclerite strip-shaped. First valve tubular, with inward protrusions. Second valve small, basally fused. Third valve broad. The anterior margin of anterior arch protrudes in the shape of two triangles. Irregularly shaped basivalvula with dense punctuations, posterior margin curled. The base of vestibular sclerite nearly hyaline, posterior margin bifurcated into two highly sclerotized spines (Fig. 14A, B ). Laterosternal shelf nearly hyaline (Fig. 14C ).

Distribution.

China (Yunnan).
