Checked: verified by a taxonomic editorNomenclature 
The grammatical root for the formation of the family name based on the genus name Orchistoma is "stomat-", not "stoma-", for it is derived from "stomatos", the genitive form of the Greek word "stoma" (compare Genus Myzostoma Family Myzostomatidae). The correct family name is thus Orchistomatidae and not as first proposed Orchistomidae. [details]
