Eriophyes? salicaesemen [listed as junior synonym of Eriophyes? semen]
Host: Salix nigra?
Relationship: Galls
Range: IL
Notes: The gall was originally described in 1864 as Salicis semen. See Chadwick 1908, p. 146, for early synonymy. This name was missed by Davis et al., 1982. Is this gall-forming mite the same as Aculus tetanothrix (Nalepa)? Is it another sibiling species? Then, salicaesemen would hold priority. Amrine & Stasny (1994) combined the two names provided by Walsh without knowing that it had already been designated semen by other authors.
