Description.

Male. Body length 5.9-6.0 mm; overall length including tegmen 6.8-7.0 mm; pronotum length × width 1.2-1.3 × 1.5-1.6 mm.

Coloration: Body generally light brownish yellow, transparent (Fig. 3 A–B). Head yellowish brown, eyes black, antenna brown. Pronotal disk brownish yellow, with hyaline anterior, posterior and lateral areas (Fig. 2A). Left tegmen brownish yellow, right tegmen brownish yellow with wide hyaline area (Fig. 4 F–G). Wings hyaline, distal portion light brownish yellow. Venation of tegmina and wings light-colored. Legs brownish yellow. Cerci brown.

Body very flat, narrow, well pubescent. Head: exposed dorsally, triangular, longer than its width, vertex nearly straight, face flat, eyes lateral, wide apart, surface with the individual facets convex, interocular space greater than the distance between antennal sockets, ocelli absent (Figs 2B, 4A). Pronotum: suboval, pubescent, anterior margin slightly protruded, lateral of anterior margins oblique, lateral margins nearly parallel, hind margin truncated, with lateral corners bluntly rounded (Figs 2A, 4B). Tegmina and wings: fully developed extending beyond the end of abdomen, venations not distinct. Tegmina pubescent except the hyaline region of right tegmen, both tegmina with free, long, simple and strong Sc, R with 7-8 oblique branches, the second and third branches intersected (Fig. 4 F–G), RA simple, M bifurcated distally, and stalked with CuA basally, CuA with 2-3 branches, major veins reticulate with some cross veins, forming many polygonal cells (Fig. 4 F–G). Wings with Sc shorter than RA, M simple, or bifurcate distally, CuA with 2-3 branches, reticulate with very a few cross veins, CuP slender, AA connects CuP medially or distally, the first AP bifurcate (Fig. 4H). Legs: Pubescent, front femur stout, apex of the hind margin with one small spine on each side, and followed with contiguous spinules (type C1), pulvilli and arolia absent, tarsal claws small, symmetrical, slightly serrated (Fig. 4 C–D). Abdomen: Supra-anal plate in dorsal view transverse, symmetrical, apex widely depressed (see the arrow in Fig. 5D), anterior and lateral margins pubescent, median hyaline broadly (Fig. 5D), cerci slender, well pubescent, apex acute (Fig. 4E). Subgenital plate generally symmetrical, pubescent, lateral parts with distinctly longer and thicker setae, apex slightly protruding, styli similar, with several long setae (Fig. 5A). Genitalia: Very complex, as Figure 5B. Left phallomere with a very elongated L3, the apex of which is curved rectangularly three times as in Figure 5C.

Etymology.

The species epithet is from the Latin word “petilus” meaning thin and little in reference to its narrow and small body.
