Materials Examined. CHINA: 13, Holotype, Tibet: Co Nag, Mama, 2900 m, 6 August 1974, coll. Huang Fusheng, slide no. L-0997, ( IZCAS); 13, Tibet: Mêdog, 2400 m, 18 August 1982, coll. Han Yinheng ( IZCAS).

Description. Antennae in male bipectinate. Labial palpus extremely long, segment I and II rough-scaled, segment III smooth, extending about 2/3 beyond frons. Frons, vertex, dorsal side of thorax brown. Abdomen with dorsal side pale brown, sparsely diffused with black scales. Wing pattern. Forewing length: 3 15 mm. Wing shape and streaks quite similar to that of S. extritonaria . Differences lie in: wing colour and streaks of neotritonaria much paler on both upper and undersides; forewing with outer margin slightly protruding outwards at middle; antemedial and postmedial lines discontinuous, not as distinct and continuous as in S. extritonaria ; postmedial line on hindwing very indistinct, hardly traceable. Venation and male hindwing basal lobe identical to those of S. extritonaria . Male genitalia. Quite similar to S. extritonaria , but gnathos with median process much larger; valva with base much broader; aedeagus much more slender. Female genitalia. Unknown.

Diagnosis. See diagnosis under the previous species.

Distribution. China (Tibet).
