Peninsular Malaysia and Sarawak 2014

Postby Neil Rowntree » Sun Aug 24, 2014 9:04 pm

Hello All,

I've recently returned from a 3-week holiday in Malaysia and was able to devote some time to herping. A few days of this was on Peninsular Malaysia but this was a bit too touristy for my liking. I then spent 2 weeks in Sarawak and was able to visit a few more interesting spots.

I'd like to give a bit more info but time only permits me to dump a bunch of photos on here for now. Not all great quality but was hoping to get some IDs.

The literature I have read so far has made me uncertain as to whether these are Tropidolaemus subannulatus or wagleri...

I've not had the time to start to identify most of the other species here, so any help would be appreciated.

Great report! About the Tropidolaemus. I am also puzzled. The Tropidolaemus subannulatus is not in my book (I see it is something from 2007). The new issue of 'A Field Guide To The Snakes Of Borneo' released in June 2014. I already had the older one (1999) and the books aren't cheap. Maybe something to buy later. Interesting to find out. :D
Finding IDs is hard sometimes. :D An Australian guy recommended this book: http://www.nhbs.com/amphibians_and_rept ... 25961.html

The Tropidophorus brookei was fascinating. The way they swim! So fast and like the iguanas on the Galapagos. :D

I will try to ID the geckos with the scorpion tails :)

Chaps, I dont profess to know a great deal about euro herps.. however I am a total geek when it comes to Asian pit vipers.. :D

..

So just to bore the pants of you..

Tropidolaemus huttoni Found in India

Tropidolaemus philippensis Found in the Philippines

Tropidoleamus subannulatus Found Philippines ( Although this is almost certainly a different species awaiting elevation), Sulawesi, Malaysia, Borneo .. often described as Tropidoleamus subannulatus celebenis from Malaysia and Tropidoleamus subannulatus immaculatus from Borneo

Tropidoleamus wagleri From Indonesia,West Malaysia

IMHO the animal 2 in your report is absolutely typical of Tropidoleamus subannulatus immaculatus from Borneo, the others less so, however Tropidoleamus is a very variable species, and colour and pattern change significantly as the snake ages. Definitive location is the only sure way to tell..

If you want any more info regarding Asian venomous species, please PM, I can talk for hours :D

Thanks Paul,

I had also read that subannulatus was the only Bornean option - but your comments seem rather more confident.
Is location the definitive factor between these subspecies?
Viper 1 was found at Kubah, Borneo, whilst the other two were on the Santubong peninsular, also Borneo.
Would this be likely that viper 2 is 'Tropidoleamus subannulatus immaculatus', but 1 and 3 may just be 'Tropidoleamus subannulatus'.
