Fw. Quednau, TAXONOMIC NOTES ON THE GENUS NEOSYMYDOBIUS BAKER WITH DESCRIPTIONS OF5 NEW SPECIES (HOMOPTERA, APHIDIDAE), Canadian Entomologist, 126(6), 1994, pp. 1443-1458
Neosymydobius neomexicanus sp.nov., N. peregrinus sp.nov., N. acutipil
osus sp.nov., N. rumorosensis sp.nov., and N. paucisetosus sp.nov. are
described and their relationship with other species is discussed. A l
ectotype of N. agrifoliae (Essig) was chosen from Essig's type specime
ns. The taxonomic position of Neosymydobius is evaluated and a key for
the identification of the presently known species is presented.
