Diagnosis. S. wolfgangi is comprised in the same subgroup as S. pendleburyi , and S. ansari . It differs from both species by smaller size and somewhat narrower, lanceolate shape of forewing; from S. pendleburyi it differs by pale ash-grey wing coloration; from S. ansari – by more distinct crosslines and stigmata. Wing coloration and pattern are similar to S. ansari , but the postmedial line clearly outlined by thin white line and basal field more ocher. In male genitalia the new species is close to S. ansari , but differs by shape of juxta, somewhat longer uncus and shorter valva. Female, like S. ansari has wide ovipositor and membranous corpus bursae, but differs well by the absence of a sclerotized extension, which substituted by a sclerotized patch in proximal part of bursa copulatrix.

Description. Adult ( Figs. 5, 6 View FIGURES 1–8 ). Wingspan: male 17–20 mm, female 21–25 mm. Head grey, tegulae and patagia ochreous-green with grey, thorax brownish-grey with greenish scales; thoracic crest not expressed; abdomen brown-grey. Forewing somewhat narrower in comparison with S. ansari , lanceolate, apically more acute than in S. ansari , with oblique terminal margin. Ground colour of forewing ash-grey; basal field ashgrey; subbasal field brownish-green, darker in costal part and with black dash between subbasal and antemedial lines; orbicular distinct, whitish, without black bordering; reniform traceable, B-shaped, with thin bordering outside; medial field ash-grey, shadowed in ventral part of wing with brown-green suffusion; postmedial line black thin, bordered outside with distinct white line, going outward from costal area, then inward and almost straight to ventral margin. Subterminal field ash-grey, with distinct strong, black subapical streak, surrounded with green scales in costal area and intensive brown-greenish suffusion in ventral half; subterminal line thin, whitish; terminal field ash-grey, suffused with brown-greenish and dark grey; terminal line consisting of a row of black streaks; cilia greyish. Hindwing pale, yellowish grey, with weakly traceable discal spot. Cilia grey.

Male genitalia ( Fig. 35 View FIGURES 33–38 ). 8 th segment of abdomen without coremata ( Fig. 50 View FIGURES 49–54 ). Uncus well developed, moderate, stronger than in S. ansari and longer than in S. pendleburyi ; tegumen and vinculum thin, vinculum 1.3 times higher than tegumen; juxta shield-like, not extended apically; transtilla well developed, with large sclerotized plates. Valva somewhat shorter than in S. ansari and less wide basally than in S. pendleburyi and S. ansari , with almost parallel costal and ventral margins, more gradually constricted apically, tipped, bearing short spine on top. Aedeagus relatively short, vesica widely-tubular, bearing large spine-like cornutus on wide base which is shorter than in S. pendleburyi and thinner than in S. ansari .

Female genitalia ( Fig. 58 View FIGURES 55–62 ). Ovipositor broad, general shape of female genitalia similar to S. ansar i, but somewhat more massive. Papillae anales broader than in S. pendleburyi , anterior and posterior apophyses rather massive, strong, but moderate in length; antrum funnel-like, shallow, like in S. ansari ; ductus bursae relatively short, narrower than those in S. ansari ; corpus bursae ovoid, with strongly sclerotized patch in proximal half of bursae, bearing horseshoe-like signum, but not forming sclerotized extension like in S. ansari .

Distribution. ( Fig. 74 View FIGURES 72–78 ). Indonesia, Sumatra. The species is rather common in Sumatra, from the lowlands up to about 1400 m. Several generations, probably around whole year.

Etymology. The species name is dedicated to Wolfgang Behounek, the son of the first author.
