Heterodera ripae Subbotin, Sturhan, Rumpenhorst & Moens, 2003

A member of the Humuli group of Heterodera spp.

Synonyms:

The nematode was originally described as Heterodera riparia by Subbotin, Sturhan, Waeyenberge & Moens, 1997 but was changed to H. ripae because H. riparia was a name alrey in us (H. riparia Kazachenko, 1993)
