''Hauffenia'' sp. nov. is an as yet undescribed (in 2013)〔Horsák M., Juřičková L. & Picka J. (2013). ''Měkkýši České a Slovenské republiky. Molluscs of the Czech and Slovak Republics''. Kabourek, Zlín, 264 pp. p. 44-45 (in Czech and English).〕 species of freshwater snail that lives underground, an aquatic gastropod mollusk in the family Hydrobiidae. This species is found in Slovakia. ==Taxonomy== The genus ''Hauffenia'' is taxonomically problematic.〔Čejka T., Dvořák L., Horsák M. & Šteffek J. (2007). "Checklist of molluscs (Mollusca) in the Slovak Republic". ''Folia Malacologica'' 15(2): 49-58.〕 Šteffek et al. (2011)〔 confirmed that the snail from Slovakia appears to belong to the genus ''Hauffenia'', based on the morphology of the penial characters.〔 However, molecular phylogeny research based on sequences of mitochondrial cytochrome-c oxidase I (COI) genes appears to demonstrate that although these snails belong to the family Hydrobiidae, they are not closely related to the genus ''Hauffenia''.〔 These snails from Slovakia may actually represent not one species but two genera: ''Hauffenia'' and ''Lobaumia''.〔 Specimens of this species are preserved in private collections.〔 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「Hauffenia sp. nov.」の詳細全文を読む スポンサード リンク
