- Common names: Transvaal quillsnout snake.
Xenocalamus transvaalensis is a venomous snake species found in Mozambique and South Africa. No subspecies are currently recognized.[1]
[edit] Conservation status
This species is listed as Data Deficient (DD) on the IUCN Red List of threatened species (v2.3, 1994).[2] This means that there is inadequate information to make a direct, or indirect, assessment of the risk of extinction based on its distribution and/or population status. This species may be well studied, and its biology well known, but appropriate data on abundance and/or distribution is lacking. Therefore, this not a category of threat or Lower Risk, but an indication that more information is required, as well as an acknowledgement of the possibility that future research will show that threatened classification is appropriate. It is important to make positive use of whatever data are available. In many cases, great care should be exercised in choosing between DD and threatened status. If the range of the species is suspected to be relatively circumscribed, or if a considerable period of time has elapsed since the last record of the species, then threatened status may well be justified. Year assessed: 1996.[3]
