| Summary: | Börnerina Bramstedt is a genus of aphids that breeds only on species of Alnus L. Inclusive of the new species described herein the genus is composed of two species, of which B. depressa Bramstedt is the European representative. Betulaphis Glendenning is a larger genus than Börnerina and as the name implies is restricted to species of Betula L. Although the genus was described in North America there have been no North American records subsequent to the original description (Glendenning, 1926). Elsewhere, the genus is known to occur in Europe, Iceland, Greenland and New Zealand. In this paper three species are recorded for North America, two of which are described as new. |
