[In the entry for Euura salicisnodus]

Notes. — This species is probably related to E. atra Jurine, a species introduced from Europe together with its host plants Salix alba L. and S. fragilis L. and their hybrids. Euura salicisnodus is separated from E. atra by its extensive paler coloration and the galls which form an enlargement of the twig. Euura atra does not produce enlargements of the twig; its galls are practically unnoticeable.
