Aphis (Aphis) popovi Mordvilko 1932

Taxonomic note on Aphis (Aphis) popovi Mordvilko, 1932 Aphis popovi Mordvilko, 1932: 291 This Ribes -living species from Yakutia (east Russia) was described by Mordvilko (1932) based on fundatrices and their immature progeny, and was redescribed by Rakauskas (1996) based on type material. This species was considered either as a member of the subgenus Aphis Linnaeus (Remaudière & Remaudière 1997; Holman 2009; Blackman & Eastop 2024; Favret 2024), or a member of the subgenus Bursaphis Baker (Blackman & Eastop 2006). It is worth mentioning that it was considered to belong to the Aphis grossulariae group in Blackman & Eastop (2024), but that these authors did not classify it as a member of the subgenus Bursaphis. It is clear that A. (A.) popovi belongs to the subgenus Bursaphis, because its fundatrices have 5–6 accessory setae on URS (Rakauskas 1996). We propose to transfer this species from the subgenus Aphis back to subgenus Bursaphis as it was suggested by Blackman & Eastop (2006).
