Redescription

Female unknown.

Length, male (holotype in parentheses), overall length including tegmen: 13.6 – 15.2 (15.2)mm; pronotum length × width: 2.9 – 3.5 (3.4)mm × 3.8 – 4.2 (4.2)mm; tegmen length: 11.9 – 12.5 (12.5)mm.

Body medium, yellowish brown (Figure 1A). Vertex yellowish brown, some individuals with irregular brown maculae (holotype without maculae). Face reddish brown, with one round reddish brown spot near antennal socket (Figure 2A). Ocellar spot yellowish white. Antennae blackish brown with base yellowish brown (Figure 1B). Fifth maxillary palpomere blackish brown with apex yellowish white, the others yellowish brown (Figure 1B). Pronotum yellowish brown, with two distinct reddish brown V-shaped maculae near hind margin; each lateral corner with one curved blackish brown stripe (Figures 1A, 2D). Tegmina yellowish brown, hind wings hyaline. First through ninth abdominal terga blackish brown; sterna yellowish brown and first through seventh segment ’ s lateral borders with black irregular maculae (Figure 1B).

Vertex with interocular space less than the distance between antennal sockets (Figure 2A). Third and fifth maxillary palpomeres approximately same length, and both weakly longer than the fourth (Figure 2B). Pronotum subelliptical, widest behind the middle (Figure 2D). Both tegmina and hind wings fully developed, extending beyond end of abdomen (Figure 1A). Tegmen with six or seven (holotype with seven) anterior rami of radius (ANT. R. RAMI) and nine to twelve (holotype with nine) apical rami of radius (AP. RAMI), one or two (holotype with two) apical rami with branches; median (M) and cubitus (CU) veins longitudinal, with complex branches (Figure 2E) . Hind wing with one anterior ramus of radius, R1 without branch; median and cubitus veins weakly curved, the former simple and cubitus vein with one complete branch after the middle, incomplete branch absent (Figure 2F) . Front femur Type A3 (Figure 2C), pulvilli on four proximal tarsomeres. Tarsal claws symmetrical, distinctly dentate (Figure 8D – F). Seventh abdominal tergum specialized with the centre hyaline and with a scattered cluster of minute setae (Figure 2G).

Supra-anal plate (Figure 2H) symmetrical in ventral view, hind margin slightly concave in the middle, posterior region scattered with six spines; right and left intercercal processes dissimilar, apex acute, left process slender with a spine-like process near the middle, pointing to the right; right process more or less short with apex branched. Left posterolateral corner of subgenital plate (Figure 2I) without obvious process, but with incision; right posterolateral corner with process perpendicular to subgenital plate; hind margin produced in the middle and bearing a conical stylus; left posterolateral margin with a large, long process (as indicated in Figure 2I) pointing to the left and somewhat upwards, whose outer margin has a row of setae; the dorsal surface of subgenital plate with one complex sclerite in centre, whose hind margin is setose; left stylus absent. Genitalia with L3 (Figure 2J) very small, without pre-apical incision; L2vm (Figure 2K) slender and apically tapering, with filamentous branch near apical third; R2 (Figure 2L) with a curved sclerite, R3 (Figure 2L) with two obvious sclerites, one of which is rod-like, the other is discoidal.

Remarks

This species is similar to S. marmorata marmorata (Brunner von Wattenwyl, 1893), but can be distinguished in the following characteristics. First, for the former, subgenital plate with a long process pointing to the left, while in the latter, the process is short. Second, intercercal processes of the former dissimilar, the right process slender with a large “ spine ”, the left one shorter with apex branched; but in the latter, symmetrical and broad, strongly curved and each with a large dark spine. Third, paraprocts of the former without spines, while in the latter, several spines are present.

Distribution
