Figure 9C

Material examined. BANGLADESH • 1 adult; Syl- het Division, Moulvibazar District , Kamalganj Upazila, LNP, trail at Janki Chora; 24°18.77′N, 091°46.66′E; 10 Jul. 2015; 20:03; photo voucher ZRC ( IMG) 2.364 .

Identification. This is a typical kukri snake with cream V-shaped face mark; it is the only species in the region to show distinct narrow pale crossbars outlined in black that repeat regularly on the body ( Das 2010; Vivek Sharma pers. comm.). Our specimens can be differenti- ated from the endemic Cambodian O. kampucheaensis , the endemic Thai O. saiyok , and the red phase of the Sundaland species O. purpurascens by the presence of 30+ dorsal rings (17 in O. kampucheaensis , 10–18 in O. purpurascens , 21–22 in O. saiyok ), seven supralabials

with III and IV in contact with eye (eight and IV – V in O. kampucheaensis , O. purpurascens , and O. saiyok ), 19 midbody scale rows (15 in O. kampucheaensis , 17 in O. saiyok ), and known species range ( Neang et al. 2012; Hasan et al. 2013; Sumontha et al. 2017).

Taxonomic notes. The presence of O. albocinctus in LNP was noted in Rahman et al. (2013b), although there was no voucher provided. We present the first vouch- ered record from Sylhet Division, which is 100 km south of the closest recorded locality in Cherrapungi, Assam ( Hasan et al. 2013; Uetz 2020).

Habitat. This species was found both in mature and degraded forest in LNP.
