title: A new species of the nearctic gall-forming genus Tamalia Baker (Hemiptera: Aphididae: Tamaliinae).
abstract: The apterous viviparous female and alate oviparous female of a new aphid species, Tamalia milleri sp. nov., a representative of a nearctic relict genus Tamalia and associated with Arctostaphylos columbiana, is described and figured in detail from specimens collected in California and Oregon (USA) and deposited in the Natural History Museum, London (UK). The differences between T. milleri and a related species, T. dicksoni Remaudière & Stroyan as well as other taxa of this genus are discussed. The distribution of Tamalia and a key to identification of the known species of the genus are provided.
