Dendrelaphis haasi de Rooijen & Vogel 2008
Another new species of the genus Dendrelaphis with a total length up to about
95cm.
We found specimens from Peninsular Malaysia (including Tioman Island), Sumatra
(including Nias, the Mentawei Archipelago and Billiton), Java and Borneo.
It is similar to Dendrelaphis pictus, but there are lots of differences. Some differences
can be seen on the pictures for others see below.
This species is named after Mr C. P. J. De Haas who collected a wealth of material that is still proving
to be of great scientific value.
Dendrelaphis haasi is imported from time to time under the name Dendrelaphis pictus.
Like all members of that genus is not easy to keep in captivity
and obviously feeds mostly on lizards. As this species was not reckognized in the past, little is known about the
biology
Differences between Dendrelaphis haasi and Dendrelaphis pictus:
D. haasi differs from D. pictus in possessing a faint, instead of bright, ventrolateral line, a narrow,
instead of broad, postocular stripe, broader vertebral scales, a lower number of temporal scales, a higher number of subcaudals,
a smaller eye, a longer tail and a parietal scale that extends further down the side of the head.
