THE TERRESTRIAL ARTHROPOD FAUNA OF THE BYERS PENINSULA, LIVINGSTON-ISLAND, SOUTH SHETLAND ISLANDS - COLLEMBOLA

As an addendum to a recent publication on the terrestrial arthropod fa una of the Byers Peninsula Site of Special Scientific Interest (SSSI), which included preliminary identification of four Collembola, we now present detailed information on Collembola occurring within the SSSI. Five species were recorded [Friesea grisea (Schaffer), Tullbergia mixt a Wahlgren, Isotoma (Folsomotoma) octooculata (Willem), Cyptopygus ant arcticus Willem, and Cryptopygus sp. nov.]. Species occurrence and abu ndance differed between samples collected from poorly vegetated stony ground and vegetation cores. F. grisea was both the commonest (58% of individuals) and the most widely distributed (18/19 samples) springtai l in the former habitat. Cryptopygus sp. nov. was recorded only in the vegetation core samples. All five species were more evenly distribute d in vegetation samples, although C. antarcticus and Cryptopygus sp. n ov. were again the least abundant. A list of the terrestrial arthropod s of the SSSI is presented.
