Size. Male 4.7–4.9 mm long, 1.3 mm wide across eyes.

Head including eyes slightly narrower than pronotum, produced somewhat anteriorly, longer medially than next to eyes, median length slightly longer than width between eyes, about 1.5 x length next to eye. Crown smooth, anterior margin of head mostly shagreen, narrowly rounded to face. Eyes fairly large ( Fig. 1 View FIGURE 1 A). Ocelli situated on anterior margin of crown and separate from eye by distance less than ocellar diameter. Frontoclypeus very long and narrow, longer than width between eyes. Antennal pits large, encroaching onto frontoclypeus. Antennal sockets situated above middle of eye. Antennae long, 1.5 x width of head or longer. Eyes notched along median margin. Clypellus expanded apically. Lorum wider than clypellus at base. Gena slightly incised below eye ( Fig. 1 View FIGURE 1 E). Pronotum as long as head, with anterior margin roundly produced and posterior margin slightly concave. Combined length of mesoscutum and scutellum slightly longer than length of head, suture curved ( Fig. 1 View FIGURE 1 A). Forewing semi-transparent, veins R1 and R2+3 reflexed, with extra reflexed costal vein on left forewing of holotype ( Fig. 1 View FIGURE 1 G) but absent on right forewing and two forewings of paratype; appendix wide, outer anteapical cell acuminate apically; inner anteapical cell open; inner apical cell short, broad, triangular ( Fig. 1 View FIGURE 1 A, B). Fore femur row AM with AM1 seta only; intercalary row with one row of thirteen fine setae; row AV setae absent ( Fig. 1 View FIGURE 1 H); fore tibia macrosetae in rows AD and PD very long ( Fig. 1 View FIGURE 1 I). Hind femur with setal formula 2+2+1, tibial rows PD with alternating short and long macrosetae, AD with 10 macrosetae, AV with ~4 long macrosetae and 14 short macrosetae ( Fig. 1 View FIGURE 1 J, K).

Coloration ochraceous with well-expressed brown or black pattern. Vertex chocolate brown at tip, with two hyaline transverse spots, aviform marking on disk reddish brown, bordered by chocolate brown, anterior margin produced medially with one concave excavation on either side, connected with eye and ocelli laterally and extending to hind margin ( Fig. 1 View FIGURE 1 A). Face chocolate brown, with transverse whitish stripes on upper part of frontoclypeus ( Fig. 1 View FIGURE 1 E). Pronotum marbled with brown, with four circular hyaline spots on anterior margin. Mesoscutum and scutellum yellowish brown, lateral margin chocolate brown, with hyaline spot at each anterior angle of scutum and lateral margin of scutellar suture, pair of small hyaline spots margined brown on either side of median line anteriorly on scutum ( Fig. 1 View FIGURE 1 A). Forewing with distal two-thirds transparent, basal third brownish with scattered unpigmented spots, bounded posteriorly with dark-brown; remainder of forewing whitish with darkening in apical margin ( Fig. 1 View FIGURE 1 A, B).

Male genitalia. Pygofer in lateral aspect longer than high, slightly narrowed posteriorly, with dorsal margin straight, dorsal incision not reaching midlength, with two subapical tufts of long setae aligned subapically and scattered shorter macrosetae more basad to midlength ( Fig. 2A View FIGURE 2. A – J ). Valve broadly triangular ( Fig. 2J View FIGURE 2. A – J ). Subgenital plate long, triangular, broad basally, lateral margin concave, with 6 uniseriate macrosetae laterally in addition to few hairlike setae ( Fig. 2J View FIGURE 2. A – J ). Style preapical lobe distinct, with several long setae; apophysis elongate, slightly exceeding subgenital plate in natural position, bent laterad near base and nearly straight and weakly tapered to apex ( Fig. 2H, J View FIGURE 2. A – J ). Connective Y-shaped, arms well developed, about as long as stem; posterior processes rather straight, divergent in dorsal view, slightly swollen near base, gradually narrowed to apex; in lateral view slightly curved dorsally ( Fig. 2I, J View FIGURE 2. A – J ). Aedeagus with well developed dorsal apodeme, shaft slightly compressed, moderately long, bent dorsally at base, then broadly arcuate in lateral aspect; in ventral view robust at base, strongly compressed apically, with pair of compressed lateral processes at apex directed laterally and then bent dorsally, gonopore apical on caudal surface ( Fig. 2C–G View FIGURE 2. A – J ).

Etymology. The species name refers to the type locality, Dinghu mountain of Guangdong Province.

Material examined. Holotype ♂, Guangdong Prov., Dinghu Mountain, 17. vii.1985, Zhang Yalin; Paratype: 1♂, data same as holotype ( NWAFU).

Remarks. The new species is very similar to S. pingtungisis , but can be distinguished from the latter by the shape of the apical aedeagal processes, which are shorter, broader and curved in the shape of horns rather than straight and slender.

Scaphoideus taishanenisis sp. nov. ( Figs. 1 View FIGURE 1 C, D, F, 3A–H, 4A–H)

Size. Male 4.2mm long, 1.1mm wide across eyes. Female 4.9mm, 1.2mm wide across eyes.

Structure as in S. dinghuensis with forewing semi-transparent, veins R1 and R2+3 reflexed, with extra reflexed costal vein. Vertex yellow with brown angular submarginal stripe and broad brown transverse band across eyes slightly produced medially ( Fig. 1 View FIGURE 1 C). Face chocolate brown, clypellus, gene and lora ventrally yellow, with transverse whitish stripes on upper part of frontoclypeus ( Fig. 1 View FIGURE 1 F). Pronotum marbled with yellowish brown, with several indistinct brown spots at anterior margin. Scutellum pale yellow with triangular marginal spot on each side of anterior margin and posterior to scutellar suture, brown ( Fig. 1 View FIGURE 1 C). Forewing transparent with basal third brownish; remainder of forewing whitish, with black to dark-brown veins and darkening in apical cells ( Fig. 1 View FIGURE 1 C, D).

Male genitalia. Pygofer in lateral view longer than broad, tapering posteriorly, posterior margin conically rounded, with two tufts of long macrosetae aligned subapically and scattered shorter macrosetae more basad to middle ( Fig. 3 View FIGURE 3 A). Valve produced caudally and rounded. Subgenital plate slender, elongate, 3.5 times longer than greatest width near base, four stout setae in oblique row near basal 0.25, in addition to few hairlike setae ( Fig. 3 View FIGURE 3 H). Style with broad anterior part and well developed preapical lobe, apical process short and evenly curved laterally, tapering to acute apex ( Fig. 3 View FIGURE 3 G, H). Connective with stem longer than arms; processes slender, needlelike, separate but closely parallel to convergent apices, in lateral aspect straight and acuminate ( Fig. 3 View FIGURE 3 F, H). Aedeagus with well developed dorsal apodeme, shaft cylindrical, straight and slightly compressed, with unpaired asymmetrical apical process attenuated, strongly decurved and extended to left of shaft, gonopore apical on ventral surface below process ( Fig. 3 View FIGURE 3 C-E).

Female genitalia. Seventh sternite about as long as wide, caudal margin medially produced with median notch ( Fig. 4 View FIGURE 4 A, B). First valvulae slightly curved dorsally with dorsal margin concave in lateral view, dorsal reticulate sculptured area located on apical half, broadening to the middle and gradually narrowing to apex, ducts extending toward ventral margin and toward membranous region ( Fig. 4 View FIGURE 4 D, E). Second valvulae, in lateral view, distinctly expanded beyond basal curvature and abruptly narrowed near apex; apex narrowly acute; shaft bearing many triangular teeth distributed on apical half behind basal curvature, ducts extending toward dorsal margin and toward apical portion of shaft ( Fig. 4 View FIGURE 4 F, G). Third valvulae with basal half narrow and apical half distinctly expanded; apex prominently produced angularly in lateral view ( Fig. 4 View FIGURE 4 H).

Material examined. Holotype ♂, Shandong Prov., Taishan Mountain, 25. ix.1974, Yang Jikun; Paratype, 2♀, data same as holotype ( CAU).

Etymology. The species name refers to the type locality, Taishan Mountain of Shandong Province. Remarks. This new species resembles S. dinghuensis sp. nov. in external shape, color and male genitalia, but differs in having the subgenital plate elongate, the style apophysis short, the aedeagus with a single process and the connective processes needlelike.
