description: 2. Scalida spinosa Qiao & Che sp. nov.
Description. Male: pronotum length×width 2.5× 3.3 mm, tegmen length 10.5 mm, body length including tegmen 13.1 mm.
Body yellowish brown. Head yellowish brown with vertex area between eyes reddish brown and a transverse light reddish-brown band between antennal sockets. Ocellar spots yellowish white. Antenna with first two segments yellowish brown, other segments dark brown. Maxillary palpomeres with the first two segments yellowish brown, third to fifth segments brown. Pronotum yellowish brown with a distinct U-shaped dark brown macula. Base of tegmina brown with costal field and part of radial field yellowish white. Vertex with interocular space equal to distance between antennal sockets. Third and fifth maxillary palpomeres about equal length, each distinctly longer than the fourth. Pronotum nearly trapezoidal, hind margin slightly arched (Figs. 2A–B). Tegmina and hind wings fully-developed, extending beyond end of abdomen. M of hind wing unbranched and distinctly curved near middle. CuA with 3 complete branches and without incomplete branches (Fig. 2E). Front femur type B3 (Fig. 2C). T7 specialized with a pair of short and wide symmetrical glands in the middle, hind margin with a broad and conspicuous concavity and a small spherical knob on each posterolateral corner (Fig. 2D).
Supra-anal plate symmetrical, hind margin produced into two spine-like processes with 3–4 small spines on each side, middle of hind margin slightly knobbed with bristles (Fig. 2G). Paraprocts asymmetrical; end of left paraproct rounded with many spines; right paraproct irregular with one large spine and many small spines in the end (Fig. 2G). Subgenital plate asymmetrical. The sides of subgenital plate rounded with bristles along the lateral borders. The hind margin of subgenital plate with a big, long process covered with many small spines at distal part. Two styli similar, slightly curved with 4–5 long spines around the apex. Hooked phallomere on the left of subgenital plate; median phallomere slender and rod-like, apex acute; right phallomere with an S-shaped sclerite (Fig. 2H).
Diagnosis. This species is similar to S. bazyluki in the shape of pronotum, supra-anal plate and subgenital plate. It differs from that species as follows: 1) CuA of hind wing with 3 complete branches in the former, while only 2 complete branches in the latter; and 2) subgenital plate with a big, long process covered with many small spines in the former, while semicircular process of subgenital plate without small spines in the latter (see Roth 1991: 5 Fig. 2D, E).
Etymology. The species name is derived from the Latin word “spinosus”, referring to the apex of styli having 4–5 spines.
Holotype. Male, Yunnan Province, Yuxi City, Yuanjiang County, Yingyuan Town, Sanbanqiao Village, 17-V-2016, Lu Qiu & Zhiwei Qiu leg. Paratypes. 2 males, same collection data as holotype.
