Westerlund was born at Berga in Kalmar County, Sweden.
He became a student in Uppsala University in 1853 and studied at Lund Unive ...
discovered and described this species under the name ''Physa sibirica'' in 1877.

Westerlund and accepted in current malacological taxonomy: a taxonomic and nomenclatorial study". ''Ruthenica'' 23: 79–108.] Starobogatov et al. moved this species to the genus ''Sibirenauta'' in 1989.
Vinarski and colleagues designated the
lectotype for ''Sibirenauta sibirica'' in 2013 and the lectotype is stored in the

The generic name ''Sibirenauta'' is feminine (according to original description), the correct species name should be ''Sibirenauta sibirica'' instead of ''S. sibiricus'' as it was cited by several authors.
