Diagnosis

Colour. Head light to mid brown, carinae paler; pronotum light brown; mesonotum orange brown, central parts and carinae paler; legs light brown; forewing hyaline straw coloured basally, mid brown apically, veins concolorous with cells, tubercles mid brown; abdominal sternites brown, intersegmental membranes yellow to orange. Morphology. Body length. ♂ 4.7–4.8 mm. Head. Apex of vertex broadly truncate; median carina incomplete, ~3/4 as long as vertex; lateral carinae slightly elevated. Frons with its maximum width around centre of frontoclypeal suture; lateral carinae slightly s-shaped. Frontoclypeal suture semicircular, median part reaching at least lower margin of antennal scape; postclypeus and anteclypeus with well developed median carina. Thorax. Pronotum with sinuate carinae; hind margin obtusely angled. Forewing less than 3× longer than wide; costa with 20–21 tubercles; fork of Sc+R basad of fork of CuA1+CuA2; position of icu at CuP distad of apex of clavus; 11 or 13 apical cells. Hind leg: tibia with 1–2 small lateral spines (without large lateral spines); six apical teeth in a row interrupted by a wide gap; 1st tarsomere with 10(–12) apical teeth and 4–6 platellae. Male genitalia. Aedeagus: phallotheca with a very long, curved spine arising ventrolaterally near apex and a shorter slightly curved spine with broad base, arising ventrally above midlength; flagellum unarmed.
Remarks. The male genitalia of this species looks very similar to that of S. ecarinata from which this species can be distinguished by the presence of a well developed median carina on postclypeus and anteclypeus and by shorter forewing. (Löcker et.al. 2006)
