Figs. 1a–1e View FIGURE 1
Adult habitus. General body color light brown. Head light brown without dark spot; triocellate, lateral ocelli margined by black pigmentation, anterior ocellus smaller ( Fig. 1a View FIGURE 1 ). Antenna yellow brown and palpi yellow brown. Pronotum light brown, narrower behind, with pale rugosities ( Fig. 1a View FIGURE 1 ). Abdominal segments pale brown. Legs yellowish. Wings hyaline with veins brown.
Male. Body length 13.2–14.3 mm, forewing length 16.5–17.8 mm, hindwing length 14.8–15.8 mm (n = 4). Tergum 9 with a patch of sensilla basiconica posteriorly; sensilla basiconica patch divided on tergum 10, distance between patches approximately equal to the patch diameter ( Fig. 1b View FIGURE 1 ). Paraprocts sclerotized, recurved upward and pointed apically ( Fig. 1b View FIGURE 1 ). Sternum 9 produced as a subgenital plate that nearly overlaps the terminus of abdomen; oval hammer present medially at posterior margin ( Fig. 1c View FIGURE 1 ).
Aedeagus mostly membranous. Aedeagal sclerites highly sclerotized, stem ca. 0.5 times as long as Y-arms. Y-arms nearly straight and parallel to each other, with tiny spines on its anterior 1⁄4 length and apex sharp; lateral sclerites slightly sclerotized, extend outward and forming a 30° angle with the straight line where the stem is located; base connected with stem, near the base of the lateral side with a slender sclerite ( Fig. 1d View FIGURE 1 ); medial sclerite nearly same length as Y-arms; the base is bent downward into an ellipse, the end is slender and rod-shaped, without spines on the surface ( Fig. 1e View FIGURE 1 ).
Female. Unknown.
Type material. Holotype: male, China: Zhejiang Province, Longquan city, Fengyang Moutain , 1290 m, 2008- V-12, leg. Liu Sheng-Long. Paratypes: 3 males, Zhejiang Province, Fengyang Moutain , 1430 m, 2007-V-4, leg. Liu Sheng-Long.
Etymology. The name refers to the parallel Y-arms of aedeagus.
Distribution. China, Zhejiang Province.
Diagnosis. The aedeagal sclerite of this species is similar to that of S. yiui . The Y-arms of both species are nearly straight. The apex of Y-arms in S. yiui (Fig. 4 in Yang and Yang 1998) are closer to each other in contrast to being nearly parallel in S. parallela ( Fig. 1d View FIGURE 1 ). Additionally, the head of S. yiui has a dark spot dorsally ( Fig. 1 View FIGURE 1 in Yang and Yang 1998) while absent in the new species.
