Diagnosis. Externally the new species is very similar to S. elegans and S. futii , but differs from the first one by clearly 8-shaped reniform and from the former by twin antemedial line and not much expressed brownish shadow in medial field, outside of antemedial line. In male genitalia it differs from S. elegans by somewhat more massive valva and from S. futii by vestigial uncus and absence of ring of minute cornuti in vesica. Corematal organ on 8 th segment of abdomen ( Fig. 52 View FIGURES 49–54 ) present, formed by thin sclerotized semiring and small gland, much smaller than in S. futii .

Description. Adult ( Figs. 15, 16 View FIGURES 9–16 ). Wingspan male 22–23, female 24 mm. Head and thorax brownishgreen, forewing brownish-green, with brownish elements of wing pattern. Basal field darker, brownish green, outlined by subbasal line; subbasal field pale brownish-green, more greenish outward; antemedial line twin, rather diffused, waved, brownish, more expressed in costal part; medial field brownish-green, with diffused semilunar orbicular, 8-shaped reniform and, diffused straight medial line, with darker brownish suffusion in ventral part of wing; postmedial line thin, black, arising from costa just above reniform incurved, to outer margin, then oblique following lateral margin; subterminal and terminal fields brownish-green, separated by diffused pale line; subterminal field with distinct brownish subterminal streak, surrounded with pale suffusion, and with brownish suffusion below whitish patch; terminal field greenish, terminal line separated in a row of brownish streaks; cilia brownish-grey, pale basally. Hindwing pale brownish-grey, darker in terminal part, with traceable discal spot; cilia brownish-grey, pale basally.

Male genitalia ( Fig. 40 View FIGURES 39–44 ). Uncus vestigial, very small, about half length of S. futii and S. javensis , apically pointed; tegumen and vinculum thin, tegumen about 1.5 times higher than vinculum; juxta shield-like, transtilla developed, with weak sclerotized plates; valva somewhat narrower and less massive compared with S. futii and S. javensis , somewhat curved and gradually tapered apically, bearing one strong spine on apex; sacculus rather massive, with saccular plate, extending above edge of valva; aedeagus more massive than in S. elegans , vesica membranous, without fine scobination as in S. elegans and ring of minute cornuti as in S. futii .

Female genitalia ( Fig. 64 View FIGURES 63–71 ). Close to S. futii . Papillae anales small, rather weak, posterior and anterior apophyses almost equal in length, antrum smaller than in S. futii , with narrower and more shallow antevaginal plate; ductus bursae somewhat longer than in S. futii ; corpus bursae narrower and longer than in S. futii .

Distribution. ( Fig. 77 View FIGURES 72–78 ). Indonesia, Java. The species occurs in mountains at elevations of 1000–1500 m.

Etymology. The species name is derived from the external similarity to Stenoloba futii .
