A new species of Aphis Linnaeus from Guangxi, China (Hemiptera, Aphididae), based on morphological characters and DNA sequences

다국어 초록 (Multilingual Abstract)

A new species of the genus Aphis with stridulatory apparatus, Aphis gnetuma Qiao sp. n., feeding on Gnetum parvifolium which is a new host plant record for aphids from Guangxi, China is described. The new species is distinguished by a well-developed median frontal tubercle and body bearing white wax powder in life. The taxonomic position of this new species is supported by analysis results of COI and gnd genes. A key to Aphis species with stridulatory spines on the hind tibiae of apterous viviparous females is provided. The type specimens studied are deposited in the National Zoological Museum of China, Institute of Zoology, Chinese Academy of Sciences, Beijing, China.
