A new indigenous species of Aphis Linnaeus (Hemiptera: Aphididae) on Muehlenbeckia (Polygonaceae) in New Zealand. New Zealand Entomologist 22

The apterous and alate viviparous, and oviparous, female morphs of Aphis cottieri sp. nov. are described from two species of the Gondwanan plant genus Muehlenbeckia in the South Island of New Zealand. Among the characteristic features of this species are: the complete absence of secondary antennal rhinaria; a once-branched media of the fore wing; well-developed frontal tubercles; and the rare to occasional absence of one or both marginal tubercles on abdominal segments I and VII; features that are also present to different extents in several other indigenous Aphidini of New Zealand and Australia. A. cottieri was parasitized by Aphidius sp. near ervi Haliday (Hymenoptera: Braconidae: Aphidiinae)
