Taxonomical notes — The three Liochthonius species found on Biz Boè are part of the “ Lapponicus ­group” ( Moritz 1976) with common features as double­pointed sensillus, small velum on relatively short dorsal setae, and within this group they are separated from other members in having setae c1 – c1 slightly more distant than d1 – d1. They were distinguished by following characters:

L. strenzkei : with small transverse crest anteriorly of setae le, notogastral setae f1, h1 on separate tubercles (not always easily visible).

L. lapponicus : without tubercles on pygidium, without transverse crests near setae le.

L. sellnicki : with transverse crests anteriorly and between setae le, with transverse crests posterior of setae f1, h1.
