Moths of Borneo 13, Malayan Nature Journal 62(1&2): 75, Pl. 2: 32, Figs 132, 133. Type-locality: Malaya : Kuala Lumpur Gardens. Holotype male, BMNH, London.

Material examined. 1 male, Indonesia, Sumatra, Dari-East , 10–30 km E Sidikalang, 800–1600 m, 6. vii 1980 (E.W. Diehl leg.), genitalia slide GB5645 ; 1 male, Indonesia, Sumatra, Aceh Tenggard , 3. xi 1983 (E. W. Diehl leg.), genitalia slide GB5315. Coll. G. Behounek, Munich.

Diagnosis. S. pendleburyi and two other Indonesian species, described here, form a separate speciesgroup, (called here the futii species-group) which could be characterized by rather similar and relatively simple wing pattern and uniformly similar shape of valva. Among other Indonesian species, S. pendleburyi and S. ansari . and S. wolfgangi described below differ from other species by the developed uncus, the presence of a single strong cornutus in the vesica, and the shape of bursa copulatrix bearing a large sclerotized patch or fully sclerotised. Adult ( Figs. 1, 2 View FIGURES 1–8 ). Wingspan: male, 21–24 mm. Forewing narrow, but slightly wider than in the allied species, with rounded apex. Ground colour of forewing mossy-green, darker in subbasal and medial part, paler and more brownish towards the apex. Basal, subbasal and antemedial lines thin, black; orbicular not expressed, reniform traceable, subapical streak distinct, outlined by ash-grey suffusion, subterminal field brown, terminal line formed by blackish vertical streaks. Hindwing brown, paler in inner part, with traceable discal spot and medial line. In male genitalia ( Fig. 33 View FIGURES 33–38 ) uncus developed, relatively short, juxta shield-like, valva wide at base, gradually narrower apically, bearing single spine on top; vesica tubular, with single strong spine-like cornutus. 8 th segment of abdomen without coremata. In female genitalia ( Fig. 55 View FIGURES 55–62 ) ovipositor short, ostium shallow, bursa copulatrix completely sclerotized

Distribution. Peninsular Malaysia, Borneo ( Holloway 2009), Sumatra.

Note. The species was described from the Peninsula Malaysia; presently we report S. pendleburyi for Sumatra for the first time.

Gabor Ronkay, Budapest) ; 1 female: Nonkodjadjar, E. Java, 4000', December 1933 (A.M. R. Wegner ), BM noctuid slide 20965 ( BMNH, London) .

Diagnosis. The new species is close to S. pendleburyi , but differs from the former by somewhat more rounded shape of forewing, pale ash-grey wing coloration, more distinct crosslines and stigmata. In male genitalia it differs by thinner and longer uncus, the shape of juxta, less tapered valva, and shorter cornutus in vesica. Female genitalia differ by having broader papillae anales, longer apophyses and shape of bursa copulatrix, which is not completely sclerotized like in S. pendleburyi but in most part membranous, bearing a large sclerotized extension at its proximal part near bottom.

Description. Adult ( Figs. 3, 4 View FIGURES 1–8 ). Wingspan 24–25 mm. Head and patagia ochreous-green with grey, thorax ash-grey with greenish scales; thoracic crest weekly expressed. Abdomen brown-grey. Forewing apically rounded, with oblique costal margin in apical part. Ground colour of forewing ash-grey with somewhat ochreous-greenish tint, most expressed in subbasal field. Basal field ash-grey, somewhat darker in costal part and with blackish dash following antemedial line in ventral part; orbicular and reniform rather distinct, bordered by thin black line. Postmedial line black, distinct, going outward from costal area, then inward and almost straight to ventral margin. Subterminal field ash-grey, with distinct thin, black subapical streak in costal area and intensive ochreous-greenish suffusion in ventral half; terminal field ash-grey, suffused with ochreous-greenish and dark grey; terminal line as a row of black streaks; cilia greyish. Hindwing yellowish brown-grey, with weakly traceable discal spot and medial line. Cilia yellowish-grey.

Male genitalia ( Fig. 34 View FIGURES 33–38 ). 8 th segment of abdomen without coremata ( Fig. 49 View FIGURES 49–54 ). Uncus developed, moderate, thinner, but about 1/3 longer than in S. pendleburyi ; tegumen and vinculum thin, vinculum 1.2 times higher than tegumen; juxta broadly rhomboidal, extended apically; transtilla well developed, with sclerotized plates. Valva somewhat shorter and narrower basally than in S. pendleburyi , more gradually constricted apically, tipped, bearing short spine on top. Aedeagus relatively short, vesica tubular, bearing large spine-like cornutus on wide base which is shorter than in S. pendleburyi .

Female genitalia ( Fig. 56, 57 View FIGURES 55–62 ). Ovipositor much broader, bursa copulatrix much shorter than in other species of the genus. Papillae anales broader than in S. pendleburyi , anterior and posterior apophyses rather massive, strong, but moderate in length; antrum funnel-like, shallow, sclerotized; ductus bursae rather short, wide; corpus bursae ovoid, with strongly sclerotized lateral extension in proximal half of bursa.

Distribution. ( Fig. 73 View FIGURES 72–78 ). Indonesia, West Java, Sulawesi (?). The species occurs in mountain zone at elevation 1400–1500 m.

Etymology. The species name is dedicated to Behnaz Bekkum-Ansari, the curator of the Lepidoptera collection in the Museum Naturalis (RMNH, Leiden).

Note. We do not include in the type series a female specimen that may be this species from Sulawesi. It slightly differs from the specimens of the type-series by its somewhat paler forewing-coloration and more contrasting pattern of the forewings and pale greyish hindwing. The genitalia of this specimen were broken during preparation: its ovipositor and antrum are similar to S. ansari , however the proximal part of bursa copulatrix, important for identification, is missing .
