Haas's Bronzeback Snake

distribution

Distribution. van Rooijen and Vogel (2008) stated that this species is widely distributed in Peninsular Malaysia, but Pulau Tioman was the only locality mentioned in their article. Since then, no subsequent article has reported the occurrence of this species in any other locality. This study reports the first locality record of this species in Peninsular Malaysia, specifically in the state of Terengganu.

discussion

Remarks. In examining specimens of D. pictus, van Rooijen & Vogel (2008) described D. haas i as a new species on the basis of several morphological characters. Dendrelaphis haasi was first recorded in Singapore in 2011 based on two museum specimens at LKCNHM and from photographs of two live specimens (Lim & Cheong 2011). The two specimens are ZRC. 2.3744 which was collected by Lee Kit Soon from an unknown locality in April 1935 and ZRC. 2.3760 which is dated “ before 1940 ”. The first live individual was photographed on 11 March 2009 at LPF, marking a rediscovery of at least 69 years after the second museum specimen (Lim & Cheong 2011). The second live individual was photographed on 16 October 2010 at USRP (Lim & Cheong 2011). Since then, three additional observations of D. haasi were documented, one at TRF on 9 March 2013 (Yeo 2013), and two at Venus Loop on 14 September 2014 (Tan 2014) and on 3 April 2016 (Sankar & Ng 2016). The individual illustrated in Figure 16 H was seen at WNP on 20 July 2020 (A. Figueroa pers. obs.). Due to modest similarities to D. pictus, there is the possibility that some earlier records of D. pictus may represent D. haasi. Occurrence. Known from a few o
