DistributionFlood plains of Indus, Ganges, and Brahmaputra rivers of Pakistan, India (Assam, Himachal Pradesh, Jammu and Kashmir, Bihar, Punjab, Uttar Pradesh, West Bengal, Orissa = Odisha), Nepal, Bhutan, Bangladesh.

Type locality: “India".  
TypesHolotype: iconotype in Hardwicke (1829 or later, see comment)
Syntypes: MNHN-RA 8339 (Va 5) [8239], MNHN 2181 (Va 5/2) [2881], and MNHN 6727 [picquotii] 
CommentDistribution: Has been reported from Thailand (Trang) by BOULENGER (cited in TAYLOR 1963), but is not listed for this country by later authors such as CHAN-ARD et al. 1999.

Types: Hardwicke and Gray’s (1827) description of Monitor flavescens was based on a drawing. According to De Lisle (2009), the “iconotype” of V. flavescens was depicted on plates 60 and 61 in Hardwicke’s (1829) “Illustrations of Indian Zoology.” This work, however, was published by Gray as a series between 1830 and 1835 (Wheeler 1998). For M. flavescens, Mertens (1942) referred to plate 67 in the second part (1834) of this work, which probably represents the “iconotype” of this taxon [Koch et al. 2013].
