Rhinariaphis - A remarkable new aphid genus from Afghanistan (Hemiptera: Aphididae: Aphidinae)

In this paper, we describe a new aphid genus, Rhinariaphis gen. nov., from the tribe Macrosiphini (Aphididae: Aphidinae) with the type species Rhinariaphis tuberculata sp. nov., from specimens that have been collected in Afghanistan, where it is associated with Lophanthus pinetorum (=Nepeta cabulica) (Lamiaceae). Rhinariaphis is superficially similar to the Hyperomyzus subgenus Neonasonovia due to its characteristically shaped siphunculi, but it is also similar to the genera Eucarazzia and Klimaszewskia because of some of the characters of the ultimate rostral segment. Representatives of this genus can easily be distinguished from other Macrosiphini genera due to the presence of numerous secondary rhinaria on antennal segments III, IV and V as well as by the thick setae on their large tuberculate bases. In addition to the taxonomy of the genus, a scanning electron microscopy (SEM) study was performed and the main morphological characters are presented with detailed descriptions of the antennal and body sensilla.
