Diagnosis.

This species can be easily separated from other species by dark brown tegmina and the extremely slender filamentous structure in the male genitalia.

Etymology.

The specific epithet is derived from the Latin word bombycinus, referring to the slender filamentous structure with which L1 is connected.

Measurements (mm).

Male: pronotum length × width: 1.35 × 1.57, tegmina length: 4.70, overall length: 6.08. Female: pronotum length × width: 1.42 × 1.68, tegmina length: 4.95, overall length: 6.26.

Description.

Coloration. Body dark brown, face brown (Fig. 8A, B ). Antennae and maxillary palpus brown (Fig. 8D ). Pronotum and tegmina dark brown, lateral edges hyaline (Fig. 8C, E ). Hind wings infuscate, costal field and appendicular field darker than remaining parts (Fig. 8F ). Abdominal sterna, legs, and cerci yellowish brown (Fig. 8B ).

Head and thorax. The distance between antennal sockets narrower than interocular space. Fifth maxillary palpus nearly triangular, slightly thicker and wider than others (Fig. 8D ). Pronotum a semicircle, anterior margin arcuate, posterior margin straight (Fig. 8C ). Tegmina with slightly indistinct veins; radius posterior veins of hind wings slightly indistinct, without transverse veins between M and CuA (Fig. 8E, F ). Front femur Type B2 (Fig. 8B ). Pulvilli absent, tarsal claws symmetrical.

Male genitalia. Supra-anal plate with sheet-like paraprocts (Fig. 8G ). Subgenital plate asymmetrical, the left margin wider than the right, the interstylar margin convex, skewed to right. The left stylus smaller than the right, the distance between them long (Fig. 8H ). L1 small, with a curved and very slender filamentary structure. L2v shaped like ‘3’. L2vm sheet-like, with dense spines. L3 medium, uncinate part with sharp apex (Fig. 8I ). R2 irregular, weakly sclerotized. R3 sheet-like (Fig. 8J ).

Female genitalia. Supra-anal plate nearly symmetrical. Paraprocts broad, extending to the posterior margin of supra-anal plate. Intercalary sclerite strip-shaped, slightly curved. First valvifer slender. First valve robust. Second valve small, basally fused. Third valve broad. The anterior margin of anterior arch protrudes in the shape of lungs with curved edges (Fig. 14G, H ). Basivalvula broad, kidney shaped, posterior margin curled, with spines at left lateral (Fig. 14G ). Vestibular sclerite small. Laterosternal shelf slightly sclerotized, lateral margin slightly curved (Fig. 14I ).

Distribution.

China (Yunnan).
