Material examined: India: 1 ♂, Arunachal Pradesh, Dibang Valley dist., Dihang-Dibang BR, Anini, Basam, 1743 m, 29.0406 °N, 95.8136 °E, 12. IV. 2018 ; 1 ♂, Pattharnallah-1, 2029 m, 29.1047 °N, 96.0807 °E, 19. IV. 2017; 1 ♂, Meyhoopey, 2314 m, 28.7873 °N, 95.9541 °E, 17. V. 2018, leg. S. Gayen & Team.

Diagnosis: Forewing length: ♂ 20 mm. In external appearance, Syntypisti s synechochlora resembles most closely to S. parcevirens (de Joannis, 1929), but differs from the latter in following features: Syntypistis synechochlora is more greenish, especially in fresh specimens, as well as much more fuscous in appearance than S. parcevirens; the sinuous postmedian fascia on forewing is complete in S. synechochlora, whereas it is only visible in costal and inner-marginal halves, being obsolete in middle in S. parcevirens . Moreover, the dark discal spot prominent in S. parcevirens is less apparent in S. synechochlora . Male genitalia of S. synechochlora shows typically slender, apically hooked and curved valvae. Prominent triangular sclerotizations of the 8 th sternite and presence of cornuti in distal part of the phallus are also characteristic to S. synechochlora .

Remarks: The species has so far been reported from China, Vietnam and Myanmar (Schintlmeister 2008) within the altitudinal range of 1800–2400 m, mostly active from June to October. In Dihang-Dibang Biosphere Reserve, the species was recorded between 1700–2300 m in East Himalayan Wet Temperate Forest habitats in the pre-monsoon months of April–May, little earlier than its past known activity period (Fig. 4).
