On 09 June 2015, a Common Water Monitor Varanus salvator (Laurenti, 1768) was observed and photographed (Image 1) on the campus of Banmaw University, Banmaw (Bhamo), Kachin State, Myanmar (24018’15”N & 97015’52”E).  Subsequently, a second individual was observed 140km to the west at Banmauk, Sagaing Division (24024’N & 95051’E); this individual had been collected locally and was being sold for food in Banmauk market. These two observations are the first records of Varanus salvator from Upper Myanmar since Anderson (1878), who obtained a single individual from Bhamo (= Banmaw), and Boulenger (1888 cited in Mertens 1942) who included a record from the Kakhien Hills (= Kachin Hills). Although the geographical distribution of V. salvator

is extensive, including Sri Lanka, northeastern India and Bangladesh through continental South-east Asia and the Sunda Islands east to the ISSN 0974-7907 (Online) ISSN 0974-7893 (Print) Moluccas and Luzon in the northern Philippines (Koch et al. 2007), OPEN ACCESS the authenticity of the historical records of Anderson (1878) and Boulenger (1888 cited in Mertens 1942) from Upper Myanmar has been questioned over the years.  For example, Cota et al. (2009) noted that despite numerous surveys, the California Academy of Sciences (CAS) had failed to find V. salvator in the central or northern regions of Myanmar. The authenticity was also challenged on account of the distribution of this species in Thailand.  Here it is common in southern, coastal areas but scarcely extends northwards, being virtually absent from the Kota Plateau in the north-east and restricted to Sukhothai Province in the north-west (Cota et al. 2009). Therefore based on data from Thailand and an absence of further sightings from northern Myanmar, Cota et al. (2009) postulated that either the historical records from Bhamo (= Banmaw) and Kachin were based on natural events, such that V. salvator dispersed northwards up the Ayeyarwady River but without subsequent records or that the specimens obtained in markets were transported as food or that they were misreported and were locality errors.
