Abstract:A detailed survey of the jumping plant-lice, or psyllids (subfamily Arytaininae) that feed on genistoid legumes in the Canary Islands and Madeira revealed a high level of endemism and diversification in this region. The taxonomy of the genus Arytainilla is reappraised to reflect a distinct origin for the predominantly Macaronesian group. The position of this island group is clarified in relation to the mainly continental Arytainilla sensu stricto which is represented in the Canary Islands by a single species. One new genus and 11 new species are described. Descriptions of previously undescribed 5th instar nymphal stages for 24 species are included. Nine of the new species (eight from the Canary Islands and one from Morocco) are described in Arytinnis gen. n., two more species from the Canary Islands are described in Arytainilla and Arytaina. In addition, 12 new combinations are proposed. A high degree of host specificity is typical and information is given on host plant associations, biology and geographic distribution. Separate keys for adults and nymphs are provided for Arytinnis gen. n. and the remaining Canary Island species.A detailed survey of the jumping plant-lice, or psyllids (subfamily Arytaininae) that feed on genistoid legumes in the Canary Islands and Madeira revealed a high level of endemism and diversification in this region.
