Turbellarian taxonomic database
Karling 1962 (citation) suggests that the two species of Euxinia may better be moved into the genus Allostoma. [p. 206], and he suggests this provisionally, referring to Euxinia in quotation marks. However, his 1993 paper (citation) makes no mention of this. Bush had this genus synonymized with Allostoma in an early version of this database, presumably on the basis of Karling (1962), but that is now reversed.
