Genus EUURA Newman 



Two subgenera have been proposed, Euura for those species whose larvae form stem, twig, or 

 petiole galls on Salix, and Gemmura for those species whose larvae form bud galls on Salix. 

 This genus is in need of study. The following is primarily a list of described species with their 

 type localities without regard to possible synonymy. According to Smith (1968) conventional use 

 of morphological characters for species separation is impossible in this group and identification 

 may have to be based on specific host data and biological information; therefore, the exact 

 identity of many of the described species may never be known.
