Aphis pilicornis Hartig, 1841

Aphis pilicornis Hartig, 1841: 369 . HOLOTYPE: (617 [7.02]), Picea .

Cinaropsis pilicornis ( Hartig, 1841) (change of combination—Börner, 1952: 43).

Cinara pilicornis ( Hartig, 1841) (change of combination— Hottes, 1953: 158). Valid

Specimens. A single pinned alate (617) collected from spruce on June 24, 1833 in Tiergarten , Berlin, Germany .

Remarks. Although its generic assignment has yet to be determined, specimen 617 does not belong to the genus Cinara as determined by the curved radial veins on its forewings and the process terminalis being greater in length than the base of antennal segment six. The specimen may instead represent a species of Periphyllus van der Hoeven, 1863 recorded from an accidental host. Given the discrepancy between the specimen’s identity and the name Cinara pilicornis Hartig, 1841 , and that the name is well established in the literature, this case will be referred to the ICZN with the recommendation that it use its plenary power to set aside the existing name-bearing type in accordance with Article 75.6 so that the prevailing use of the name may be maintained and that a neotype be designated.
