Lipaphis (Lipaphis) erdemi sp. nov. is described from apterous and alatae viviparous females collected in Central Anatolia (Türkiye) on Sisymbrium sp. (Brassicaceae). The new species is markedly different from the other species of the subgenus Lipaphis by having secondary rhinaria on the antennal segments III, IV and frequently V in apterous viviparous

Miyazakia, a new aphid genus from Japan (Hemiptera: Aphididae: Macrosiphini)
Zootaxa, 2014Miyazakia gen. nov. with type species Miyazakia ranunculi (Miyazaki, 1971) comb. nov. is described. The species is illustrated and biometric data are provided for all morphs, except the fundatrix. This aphid genus is closely related to Sappaphis Matsumura, 1919. M.

Abstract The large raspberry aphid, Amphorophora idaei , has several biotypes described by their abilities to overcome plant resistance genes. Bioassays of field populations showed a strong shift towards A, resistance‐breaking biotypes since the 1960s.

Blanchardaphis was erected for two Argentinian species of aphids very similar to Uroleucon, but distinguished by several characters. Here, we examined morphology and DNA sequences of Blanchardaphis specimens from Argentina and Chile. We further conducted a phylogenetic analysis to determine the relationship of Blanchardaphis to Uroleucon.

BLANCHARDIA POIKILA GEN.NOV., SP.NOV. (HEMIPTERA: APHIDIDAE, MACROSIPHINI) IN MENDOZA, ARGENTINA
The Canadian Entomologist, 1997AbstractBlanchardia gen.nov. and its type species Blanchardia poikila sp.nov. are described and the new combination Blanchardia capitophoroides is established for Macrosiphum capitophoroides Blanchard, 1944. The new genus forms part of the Macrosiphum group and it is characterized by the presence of one to three poorly defined rows of cells on the apex

A new genus and species of tribe Macrosiphini (Hemiptera, Aphididae) from northeast China
Zootaxa, 2008Brevisiphonaphis hirsutissima gen. nov., sp. nov. is described from specimens collected in northeast China on Artemisia argyi H.Lév. & Vaniot (Asteraceae). The genus is illustrated with the biometric data for apterous viviparous females. This aphid genus is closely related to Microsiphum Cholodkovsky, 1902 and Microsiphoniella Hille Ris Lambers ...

AbstractWe performed molecular and morphological analyses to determine the generic limit of the genusAulacorthum, including several species with controversial taxonomic histories. The sequences of four mitochondrial genes,COI,COII,srRNAandlrRNA, and one nuclear gene,EF1a, implied thatAulacorthumis not monophyletic, withAulacorthum ...

New species of the aphid tribe Macrosiphini (Homoptera, Aphididae, Aphidinae) from Kazakhstan
Entomological Review, 2016Two new species of the genera Uroleucon Mordvilko, 1914 and Pleotrichophorus Borner, 1930 are described from Kazakhstan. Uroleucon dzhungaricum sp. n. feeding on Senecio nemorensis L. (Asteraceae) in the Dzhungar Ala Tau is closely related to U. minor (Borner, 1940). Both these species differ from the closely related U. solidaginis (Fabricius, 1794) in
