Material Examined: India: 1 ♂, Arunachal Pradesh, Dibang Valley dist., Dihang-Dibang BR, Anini, Oldschool, 1642 m, 28.7992 °N, 95.9145 °E, 21. IV. 2017 ; 2 ♂, Bruni-1, 2243 m, 29.1412 °N, 96.1234 °E, 13. V. 2017; 1 ♂, Mippi , 2066 m, 28.9947 °N, 95.8059 °E, 23. V. 2017; 5♂, Basam, Chapupani , 1968 m, 29.0543 °N, 95.7836 °E, 26. V. 2017, leg. S. Gayen & Team.

Diagnosis: Forewing length: ♂ 20.5–22 mm. Forewing ground colour is reddish-brown, mixed with fuscous, while all the lines are marked with fuscous. In markings, the species superficially resembles Syntypistis perdix ( Moore, 1879) , whose ground colour is rather whitish with lines and patches marked with greyish-black, additionally with a black basal streak in forewing lacking in S. witoldi . The hindwing of S. witoldi lacks any prominent band other than fuscous-brown costal band, with medial dark shading. In S. perdix there is a fine medial line followed by a dark postmedial band, both prominent only on costal half, further followed by an almost complete marginal pale band. In male genitalia, the valvae of S. witoldi is broad, highly sclerotized and its apex is club-shaped, whereas, S. perdix possesses the characteristic valval apical curve. The phallus of S. witoldi is longer and slenderer in appearance than S. perdix . The 8 th sternite is slightly bulged at the posterior margin with flat top lacking the characteristic short central projection as in S. perdix .

Remarks: The species was common in the very adjacent landscapes of Myanmar, Vietnam, Thailand and Yunnan province of SW China ( Schintlmeister 2008) and present record from Dihang-Dibang BR within 1600– 2200 m altitude zone in the Wet Temperate Forest habitats signifies the inclusion of thirteenth Syntypistis species from India ( Fig. 4 ).
