Redescription of Friesea handschini Kseneman, 1938 (Collembola, Neanuridae) with notes on intraspecific variability of the species

摘要

Examination of Friesea handschini Kseneman, 1938 (Collembola, Neanuridae) specimens from the type locality and nearby regions of the Romanian and Ukrainian Carpathians has shown that the original description and redescriptions were inaccurate. Detailed and fully illustrated redescription of the species is given and chaetotaxy variability is discussed. A neotype is designated for the species. Tetracanthella ksenemani Nosek, 1964 found in samples with F. handschini is reported as new for Romania.
