Morphology.Head inverted triangular, with epicranial suture convex. Compound eyes ovoid. Antennae longer than fore wing. Fore wing membranous and glabrous; Sc ending free in membrane, Rs and M connected by a crossvein; pterostigma triangular with apex moderately rounded; distal closure of discoidal cell slight concave; areola postica with very narrow apex, vein M3 paralleled to Cu1a; radial fork branches diverge at an angle less than90°. Hindwing without marginal setae between R2+3 and R4+5. Abdomen ovoid. Phallosome (Fig. 9&10) a closed frame invaginated subapically, with broad posteriormargin concave medially. Hypandrium (Figs. 11&12) upturned distally and laterally, with posteriormargin emarginate deeply. Clunium (Fig. 13) with posteriormargin convex medially and invaginated bilaterally. Epiproct (Fig. 13) round, unsclerotized medially; paraproct oblong, with slender apical spine, sensory field with about 36 trichobothria. Measurements. Bw: 6542, B: 3604, FW: 5307, HW: 3617, F: 1173, T: 2267, t1: 643, t2: 261, f1: 1467, f2: 1567, f3: 1533, Mx4: 242, IO/d: 2.095. Female. Coloration(in alcohol). Same as the male. Wings ( Fig. 3): Fore wing hyaline with brown markings: a band from middle of cell R to middle of vein 1A, a broad band from hind corner of pterostigma to distal corner of discoidal cell, a band from hind corner of pterostigma to radial forks leading to distal two-thirds of cell R5 with a hyaline spot submarginally, markings along posteriormargin of areola postica and at entire cell M3, markings bordering cell M1. Morphology.Head same as the male. Fore wing: Sc ending free in membrane, pterostigma with moderate hind angle, Rs-M meeting at a point, distal closure of discoidal cell slight concave, areola postica with narrow apex, vein M3 parallel to Cu1a, radial fork branches diverge at an angle less than90°. Hindwing without marginal setae between R2+3 and R4+5. Abdomen ovoid. Subgenital plate (Fig. 14) with egg guide short and round apically, pigmented arms forming roughly T-shaped regions expanded anterolaterally, with membranous regions distromedially. Gonapophyses (Fig. 15): ventral valve slender; dorsal valve broad and pointed apically, with a field of short setae ventrolaterally; outer valve elliptical, with posteriorlobe. Epiproct triangular, distal margin moderately round; paraproct triangular, sensory field with about 43 trichobothria. Measurements. Bw: 8755, B: 4642, FW: 6583, HW: 4427, F: 1272, T: 2583, t1: 723, t2: 283, f1: 1727, f2: 1873, f3: 1623, Mx4: 271, IO/d: 3.455.
Material examined. CHINA: 1 maleand 4 females, Yunnan Province, Ruili C., Mengxiu To., 5.v.1981, Chikun Yang (CAU); 1 male, same location, 2.v.1981, Fasheng Li (CAU).
Distribution. China(Yunnan).
Remarks.The species is closely related to Clematoscenea macalpineiSmithers & Thornton, based on similarity of fore wing pattern, however, the two species can be distinguished by the genitalic characters (Li, 2002). The species shows sexual dimorphism in wing pattern as does C. dimorphaSmithers & Thornton.
