W. Diehl leg.). The type series is in the collection of G. Behounek, to be deposited to ZSM, Munich, Germany. Diagnosis. S. benjamini externally differs from other known Indonesian species by light greenish wing coloration with grey suffusion, with distinct, rather contrasting pattern formed by thin black crosslines. It is close to S. robusta, but well differing by coloration and pattern of wing with indistinct reniform and more regular antemedial line. In male genitalia it differs by somewhat longer uncus, thinner valva and broadly tubular scobinated vesica. In female genitalia it differs by smaller and narrower antrum and shape of corpus bursae. Description. Adult (Figs. 21, 22). Wingspan: male, 20–22 mm, female 21–23 mm. Head and thorax pale olive-grey; thoracic crest expressed, brownish; ground colour of forewing pale olive-grey with grey suffusion; basal field whitish, with blackish suffusion, bordered with whitish suffused line; subbasal field pale olivegreyish; antemedial line twin, black, bordered inside in ventral part of wing by white line; medial field behind antemedial line greyish, olive-greyish in costal and central areas, suffused with whitish and grey scales around reniform to apical angle; orbicular and reniform weakly expressed in male, traceable in female; orbicular rounded, reniform 8-shaped, both stigmata bordered with blackish scales; postmedial line thin, black, bordered outside by white line or suffusion; subterminal and terminal fields weakly separated by diffuse whitish line; subterminal streak prominent, black; subterminal area suffused with whitish and black scales; terminal line expressed as broken row of small streaks; cilia grey, basally whitish. Hindwing brownish-grey, darker towards apex, paler or whitish basally and around ventral margin; cilia whitish, chequered with black. Male genitalia (Fig. 44). 8 th sternite of abdomen with corematal organ, formed by sclerotized semiring and small gland with brush of hairs. Uncus vestigial, small, similar to S. robusta, but longer than in S. viridibrunnea; tegumen and vinculum thin, tegumen about 1.5 times higher than vinculum; juxta shield-like, transtilla weak, with sclerotized plates; valva somewhat thinner and less curved compared with S. robusta and S. viridibrunnea, gradually tapered apically, bearing one strong spine on apex; sacculus elongate, not massive like in S. robusta and S. viridibrunnea, saccular plate not extending above edge of valva; aedeagus rather short and massive, vesica broadly globular, curved ventrally, much wider and stronger than in S. robusta and S. viridibrunnea, with fine scobination. Female genitalia (Fig. 66). Papillae anales small, rather weak, apophyses posterior shorter than apophyses anterior, antrum smaller and much shorter than in S. robusta, ductus bursae thinner and longer; corpus bursae elongate, with prominent appendix bursae. Distribution. (Fig. 79). Indonesia, Sumatra. It is rather common from the lowlands to montane forests up to elevations of 1400 m. Several generations per year. Etymology. The species name is dedicated to Benjamin Behounek, the grandson of the first author.
