Faunistic Note.

Fossil remnants of Elaphrus sibiricus Motschulsky, probably about 2.0-2.5 million years B.P., have been unearthed from northwestern Yukon Territory (Elias and Matthews 2002: 914) and northwestern Greenland ( Böcher 1995: 22). The species is currently found in Siberia, Japan, Mongolia, and Inner Mongolia in China (Goulet 2003: 207).
