Amphisbaena caiari is a species of reptile from the family of the double snakes (Amphisbaenidae).
description
Amphisbaena caiari is a small Amphisbaena species with a head-trunk length of 157 millimeters. The species has two pores in front of the cloaca , which are arranged in a row. The snout is rounded both from the side and from above, as is the tip of the tail. There are 233 to 250 annuli on the body and 20 to 24 on the tail. The point at which the tail can be thrown off ( autotomy ) is in the area of the annuli 6 to 9. Approximately in the middle of the body there are rarely 9, usually 10, and on the belly 12 to 14 segments per annulus. A postmalar row is missing behind the cheeks. The seam between the frontals is slightly shorter than that between the parietals and the nasals . The tail is short compared to the body, the ratio of tail length to body length is only 0.10.
Occurrence
The species is so far only known from the middle Rio Madeira (western Amazonia, Brazil). Most of the specimens were found in forests on the left side of the river, only one on the right side of the Rio Madeira and in the open savannah. All of them were buried in the ground or under tree trunks.
Systematics
Amphisbaena caiari was first described in 2014 by Mauro Teixeira Jr., Francisco Dal Vechio, Antonio Mollo Neto and Miguel Trefaut Rodrigues . The species is named after the name of the indigenous Tupi language for the Rio Madeira caiari .
