Researchers have found a brand new venomous snake species of the genus Bungarus in Thailand. The elapid snake was found in Ratchaburi Province in western Thailand. It hails from the Tenasserim Mountain Vary.
The snake, Bungarus sagittatus sp. nov. is within the household Elapidae and is the 18th snake species of the Bungarus genus. Snakes on this genus are discovered all through a lot of Asia, from Southeast Asia to China, during South Asia and into Iran. Thailand is understood to be residence to 5 species within the genus, together with B. candidus, B. fasciatus, B. flaviceps, B. slowinskii and B. wanghaotingi. Bungarus sagittatus sp. nov makes Thailand residence to 6 venomous snake species within the genus.

Bungarus sagittatus sp. nov. has black and white crossbands, just like these of most different snakes within the genus. In reality, some are identified by the widespread identify black-and-white banded kraits, although the venomous krait species differs morphologically. These of the B. candidus, B. multicinctus, and B.wanghaotingi advanced are so comparable that mitochondrial DNA, exterior morphology and cranial osteology was employed to verify that the snakes had been certainly separate species.

As with these three within the advanced, Bungarus sagittatus sp. nov. can be a black-and-white-banded krait. It differs from others within the Bungarus genus based mostly on its “enlarged, hexagonal-shaped and midbody vertebrae scales.” The holotype is an grownup feminine with head size of 19.9mm. 16.8mm head width, head top of 10.7mm and a head that’s 1.2 instances longer than huge. The physique size from snout to vent is 791mm, and a tail of 132mm for a complete size of 923mm. The snake has differing colour patterns and morphological variations from others within the Bungarus genus.
New Krait Species Found In China
Observations of Bungarus sagittatus sp. nov. occurred largely at night time. three specimens had been collected in hill evergreen forest at 834 to 987 meters above sea stage. A subadult was noticed consuming an grownup Reeve’s clean skink (Scincella reevesii), a skink endemic to Asia. This snake was not collected.
