''Balea sarsii'' is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Clausiliidae. The species has long been overlooked because of confusion with ''Balea perversa''. ==Taxonomy== The specific name ''sarsii'' is in honour of Norwegian biologist Michael Sars. According to Welter-Schultes ''Balea heydeni'' is conspecific with ''Balea sarsii''. The name ''heydenii'' has now been superseded as the species was described from Norway at an earlier date than von Maltzan, under the name ''sarsii'' Pfeiffer (synonym ''lucifuga'' Bourguignat 1857). This species has been separated from the closely related, common and wide-spread ''Balea perversa'' and redescribed by Gittenberger et al. (2006)〔Gittenberger E., Prece R. C. & Ripken T. E. J. (2006). "''Balea heydeni'' von Maltzan, 1881 (Pulmonata: Clausiliidae): an overlooked but widely distributed European species". ''Journal of Conchology'' 39(2): 145-150.〕 under its junior synonym name ''Balea heydeni'' von Maltzan, 1881.〔 The valid name for this taxon is, however, ''Balea sarsii''.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Balea sarsii」の詳細全文を読む スポンサード リンク
