Geographic range

Kentropyx borckiana is found in Guyana, French Guiana, Suriname, and on the Caribbean island of Barbados.

Parthenogenesis

K. borckiana is apparently a rare unisexual clone that reproduces through parthenogenesis, in that only 100 female museum specimens are known to exist and no male specimens. It is believed to have arisen from hybridization between Kentropyx calcarata and Kentropyx striata.

Etymology

The specific name, borckiana, is in honor of Johann Graf von Borcke (1781-1862), a major in the Prussian Army who fought in the Napoleonic Wars.[2] Borcke presented a number of specimens to the Berlin Museum.[2]

Description

Kentropyx borckiana grows up to 100 mm (3.9 in) snout-to-vent. Its head and neck are greenish, with white underneath. Its sides are brown, and its underbody is pinkish. Its dorsal surface is gray to pinkish-brown, with light lateral stripes bordered with dark bands.

Similar species

A population of lizards on Trinidad was originally thought to be K. borckiana, but has since been identified as another species.

gollark: Any reliable past/future information channel would be data-mined to death, I think.
gollark: I mean, yes, FTL is equivalent to time travel, but I didn't mention that.
gollark: What does a warp drive have to do with this?
gollark: Like I said, if you could reliably get future information/transmit information backward in time, that would be ridiculously powerful.
