Stenoloba viridibrunnea Behounek & Kononenko sp. n.

( Figs. 19, 20 , 43 )

Type material. Holotype: male, [ Indonesia] Sumatra, Dairi Mts. ( West of Lake Toba ), 1500 m, 8.–9.xi.1980 (E. W. Diehl leg.), genitalia slide GB5647male . Paratypes: 1 male, same locality, data and collector; genitalia slide: GB5316 male; 1 m, same locality and collector, 30.vii–3.viii 1981, genitalia slide: GB7209 male. The type series is in the collection G. Behounek, to be deposited to ZSM, Munich , Germany .

Diagnosis. The new species differs externally from its allies by dark mossy-green ground color of forewing with black and whitish elements of wing pattern. In male genitalia it is close to S. robusta , but differs by shorter and wider uncus, somewhat less arched and wider valva and long tubular vesica with small basal diverticulum. Female unknown.

Description. Adult ( Figs. 19, 20 ). Wingspan: male, 19–21 mm, female 22–25 mm. Head, thorax and ground color of forewing brownish mossy-green; basal field mossy-green, in costal area bordered by black basal line and surrounded with white diffused line; antemedial line twin, formed by dentate blackish line; medial field mossy-green, darker in inner part; medial line marked on costal area by black diffused line; orbicular indistinct, traceable as two whitish dots; reniform 8-shaped, bordered by black, with twin white nucleus inside, surrounded with whitish suffusion extending to costa; postmedial line arising from costal margin behind reniform, black with white surrounding, little waved; subterminal and terminal fields mossygreen, weakly separated by indistinct white line, with whitish suffusion in costal part; subapical streak distinct dark brownish-green; terminal line as row of broken streaks; cilia brownish-green, whitish in front of veins. Hindwing brownish-grey, darker towards outer margin, with traceable discal spot and medial line; cilia brownish-grey, pale grey-yellowish basally.

Male genitalia ( Fig. 43 ). Uncus vestigial, small, about half length of S. robusta , rather broad, apically pointed; tegumen and vinculum thin, tegumen about 1.5 times higher than vinculum; juxta shield-like, transtilla weak, with weakly sclerotized plates; valva somewhat more massive compared with S. robusta , less curved and gradually tapered apically, bearing one strong spine on apex; sacculus rather massive, with large saccular plate, extending above edge of valva; aedeagus shorten than in S. robusta , vesica membranous, tubular, with subbasal diverticulum, without scobination or minute cornuti.

Distribution. ( Fig. 78 ). Indonesia, Sumatra. The species is known only from its type-locality, it occurs in mountains at an elevation of 1500 m.

Etymology. The species name is derived from its characteristic brownish-green wing coloration.
