Taxonomy Mactrotoma was treated by Signorelli (2012) as a synonym of Standella Gray, 1853, assuming as type species Mactra fragilis Gmelin, 1791. However as pointed out by Dall (1898) and Huber (2015: 834), Mactra "fragilis" was misidentified in Gray (1853) and ICZN art. 70.3 applies, the intended species for Standella being Mactra pellucida Gmelin, 1791, a very different species now placed in the subfamily Lutrariinae. The type species designation under art. 70.3 was implicit from Dall (1898) and formally made by Huber (2015). [details]
