Jumping plant lice (Homoptera: Psylloidea) of the temperate neotropical region. Part 2: Psyllidae (subfamilies Diaphorininae, Acizziinae, Ciriacreminae and Psyllinae)

Three families of Psylloidea are known to occur in temperate South America. Four subfamilies of the Psyllidae (Diaphorininae, Acizziinae, Ciriacreminae and Psyllinae) are revised in this paper. The Diaphorininae with one genus containing 18 species are an important element of the fauna of Nothofagus. Each Nothofagus species seems to be the host of at least one psyllid species. Other host plants of the genus are Compositae and Myrtaceae. The Acizziinae and Ciriacreminae are represented by six species in three genera and nine species in three genera, respectively. In the New World these two subfamilies have a predominantly tropical distribution and are associated with Leguminosae. The Psyllinae are represented by a single introduced species on pear. One genus and 18 species are described as new. One new generic and four new specific synonyms, and ten new combinations are proposed. One species name becomes a secondary homonym and is replaced. The descriptions of adults are supplemented by information on larvae and host plants. Lectotypes are designated for six species. Keys are provided for identification to species level.
