Pteroclorini or Pterochlorini ?

Mordvilko (1914) established the tribe name “ Pterochlorini ”, Pterochlorus Passerini being the name-bearing genus. However, Pterochlorus is an unjustified emendation of Pteroclorus Rondani, 1848 ( Passerini 1860) , as recognised by most aphidologists, for example, Börner (1952) and Eastop & Hille Ris Lambers (1976); and the fact that Nieto Nafría et al. (2003: 308) considered Pterochlorus as a mistake for Pteroclorus .

Baker (1920) used Pterochlorina as a valid subtribe name, and Nieto Nafría et al. (1998a) considered it a junior synonym of Lachninae , also writing it with “ch”. However, the correct spelling of the taxon is Pteroclorini , because «A family-group name is an incorrect original spelling and must be corrected if it is formed from an unjustified emendation of a generic name (unless the unjustified emendation has become a substitute name)» [I.C.Z.N. article 32.5.3.2], and «The correction of an incorrect original spelling in accordance with the article 32.5 is a "justified emendation", and the name thus corrected retains the authorship and date of the original spelling» [I.C.Z.N. article 33.2.2].

However, on the other hand Pteroclorini is an objective invalid name because it comes from the name of the genus which is an objective synonym of another genus, Lachnus Burmeister, 1835 .
