Stictane transversana Bayarsaikhan & Bae View in CoL , n. sp.

( Figs 11 View FIGURES 10–14 , 25 View FIGURES 24–25 )

Type materials. Holotype: 1 ♂, Cambodia, Bokor , Kampot Prov. (N10˚39′30.88″, E104˚03′07″), 10.II.2015 (YS Bae, YD Ju, BS Park, SM Na, JW Kim, DJ Lee), Gen. Slide No. INU˗1265 . Paratype. (1 ♂) Cambodia : 1 ♂, Phnom Kulen National Park , Siem Reap Prov. (N13˚36′43″, E104˚06′55″, Alt. 839m), 15.II.2013 (YS Bae, YD Ju, BS Park, HJ Lee), Gen. Slide No. INU˗1443 .

Diagnosis. Male genitalia structure of the new species is differs from all of described Stictane species by having an apex of valva sharply angular, with short spine on lower angle and costal margin of valva with an angular projection at half of costa and a large spine˗shaped projection at 1/3 from apex.

Description ( Figs 11 View FIGURES 10–14 a–b). Length of forewing 6 mm in male. Head and frons pale gray; labial palpus dark, slen- der, upturned over vertex. Patagium and tegula fuscous gray. Thorax dark gray. Femur, tibia and tarsus of forelegs dark gray. Femur of midlegs with fuscous gray; tibia dark gray, a pair of spurs in middle part (one short, another one long); tarsus dark. Hindlegs with femur gray; tibia pale gray, with a pair of spurs in middle part (one short, another one long) and a pair of spurs in apical part (one short, another one long); tibia fuscous. Ground color of forewing light gray, with antemedian series of three dark spots distinct; straight medial dark band broadly diffuse distally; a discoidal dark spots distinct; postmedian series of dark spots convex outward; before apex with a fuscous patch; terminal series of spots dark; fringe gray, except fuscous apical half. Hindwing gray, with fuscous apical area; fringe gray.

Male genitalia ( Figs 25 View FIGURES 24–25 a–b). Uncus slender, hook˗shaped, with a small spine at tip. Valva symmetrical, weakly sclerotized, with weakly setose in apically; apex of valva sharply angular, with short spine on lower angle; costal margin of valva strongly sclerotized in basal half, with an angular projection at half of costa and a large spine˗shaped projection at 1/3 from apex. Saccular process slender, sickle˗shaped, extend into spine˗shaped projection of costal margin. Juxta rectangular, weakly sclerotized. Aedeagus stout and vesica with a long, slender and a row of short spines, and finely scobinate.

Female genitalia. Unknown.

Distribution. Cambodia (Kampot and Siem Reap provinces).

Etymology. The specific epithet “transversana” refers to the transverse central marking on the forewing.

Remarks. Table 1 View TABLE 1 . describes the external features that distinguish this new species from the genital structures not examined three Vietnamese species ( Figs 12–14 View FIGURES 10–14 ).
