Review of Mesocallis Matsumura from China (Hemiptera, Aphididae), with one new species

Abstract

The aphid genus Mesocallis Matsumura in China is reviewed. A total of seven species are recognised using morphological characteristics, including six known species, Mesocallis (Mesocallis) alnicola Ghosh, M. (Paratinocallis) corylicola (Higuchi), M. (M.) pteleae Matsumura, M. (M.) sawashibae (Matsumura), M. (P.) yunnanensis (Zhang) and M. (M.) taoi Quednau, and one new species, M. (M.) platycaryae Qiao, sp. nov. The new species, collected on Platycarya strobilacea (Juglandaceae) in Anhui Province, China, is described and illustrated. A key to Mesocallis species from China is presented.
