Cryptopygus cisantarcticus Wise, 1967

Cryptopygus cisantarcticus is a species of springtail belonging to the family Isotomidae.[1] The species was first described by Keith Arthur John Wise in 1967.[1] The species is native to the Cape Hallett area of Northern Victoria Land in East Antarctica and the surrounding offshore islands, including the Balleny Islands.[2]

Taxonomy

Cryptopygus cisantarcticus was identified in 1967, when Wise recognised consistent differences between Cryptopygus antarcticus found in the Cape Hallett area of Antarctica and the near-by Balleny Islands.[2] The first known specimen was collected in 1962 by Madison E. Pryor, who identified it as Cryptopygus antarcticus.[2] Genetic evidence suggests that Cryptopygus cisantarcticus diverged from other Antarctic species around 18-11 million years ago, possibly due to increased glaciation creating barriers between populations.[3][4]

Description

The species is deep blue to black in colour, with a body length of up to 1.75 mm (0.069 in).[2] It can be distinguished from Cryptopygus antarcticus by the position and length patterns of the posterior setae.[2]

Distribution

The species is known to occur in the Cape Hallett area of Northern Victoria Land in East Antarctica and the surrounding offshore islands, including the Balleny Islands.[2] The species is primarily found in moist algal flats,[5] or underneath rocks in association with moss.[6]
