Researchers have discovered two new species of pitviper in Southeast
Asia. After collecting snakes throughout the Asian tropics—Thailand,
Laos, Vietnam, and Cambodia—researchers were able to parse out a more
complex set of species than had been recognized. One of the new vipers
has been dubbed Cryptelytrops rubeus for its ruby-colored eyes.
Over 12 years of work researchers conducted genetic tests, looked at
physical differences, and then geographical separations of various
viper populations that were all considered big-eyed pitviper
(Cryptelytrops macrops). Out of the various population two new
distinct species have been described: Cryptelytrops rubeus and
"They are genetically distinct at mitochondrial and multiple nuclear
genetic markers, and are geographically separated, occupying different
mountainous areas […] There are some superficial differences involving
the color of the eye, the presence and width of lateral stripes on the
head and body and so on, but they are quite subtle," co-author Anita
Malhotra, a molecular ecologist at Bangor University, explained to
Although little more is known about the behavior or status of the
species in the wild, Malhotra says it is possible they are threatened.
"Depending on the species, the main threats are habitat destruction,
and over-collecting (the vast majority of the latter is for
traditional medicinal use, in some cases also for other purposes such
as leather and the captive trade)," she told mongabay.com
Each of these pitviper species are poisonous and dangerous, although a
bite is not usually fatal to humans.
The paper will appear in Zootaxa.
