Validity Ferguson 1954 states that Macrostomum gabriellae Marcus, 1949 from Brazil is a synonym of Archimacrostomum beaufortense (Ferguson, 1937) from Noth Carolina, USA. Given the issues with Archimacrostomum (see notes there), it should thus probably be referred to as Macrostomum beaufortense. However, given the extensive convergent evolution among hypodermically-mating species, as suggested by Brand et al , it is unclear whether that synonymy is reasonable, also considering the there are many very similar species in other parts of the US East Coast.
