The subspecies L.d. gammiei Pradesh, hilly forests of northeastern India (Khasi Hills), (Moore, [1892]) has a distributon extending from from 1,800–2,200 m with a fight period from April to Sikkim to Arunachal Pradesh including Bhutan and November (Evans 1932; Wynter-Blyth 1957; Sbordoni northeastern India with males being “not rare” while et al. 2015; Kehimkar 2016; van Gasse 2017) (Fig. 1). females being “very rare”; the nominate subspecies L.d. A specimen of L.d. gammiei from Sikkim (1 male) was dura (Marshall, 1882) occurs in northwestern Yunnan, collected by O.C.
