A Cryptic Species of Aphis Gossypii (Hemiptera: Aphididae) Complex Revealed by Genetic Divergence and Different Host Plant Association

Bull Entomol Res. 2015 Feb;105(1):40-51. doi: 10.1017/S0007485314000704. Epub 2014 Nov 21.

Abstract

Three cryptic species, Aphis gossypii, Aphis glycines, and Aphis rhamnicola sp. nov., are recognized as sharing buckthorn plant, Rhamnus spp. as primary hosts. These aphid species have morphological similarities; however, there are significant genetic differences between the three cryptic species. Based on the high level of genetic divergence and the different secondary host association, we described a new species, Aphis rhamnicola sp. nov., for apterous and alate vivipara, fundatrix, ovipara, and gynopara, including diagnostic key for the host sharing species in the genus Aphis.

Keywords: Aphis gossypii; COI; Rhamnus; host plant association; new cryptic species.
