From editor or global species database
Spelling There is no doubt that Grube was using the genus Siphonostoma Otto, 1821, however, Grube named a new taxon as Siphonostomum papillosum and in the process he changed Otto's (1821) Siphonostoma (first introduced as Siphostoma Otto, 1820) to Siphonostomum, for unknown reasons. It may have been a simple lapsus, as Grube used the heading of "Siphonostomum Otto", so never intended to introduce a new genus. 'Stoma' is a correct transliteration from a neuter Greek noun, but 'stomum' is also widely used as a neuter noun and Grube may have been more familiar with that spelling. [details]
