Extract

This paper includes descriptions of a new species of Cinara and one of Micromyzus.

The species of Cinara belongs to the species group in which the base of the cornicle hears both heavy and fine setae. In other members of this group the heavy and fine setae are evenly distributed over the surface of the base of the cornicle, but in the species described here the fine setae are clustered around the orifice and the heavy ones are closer to the margin of the base than in related species (Fig. 4). Another difference is that the dorsum of the abdomen is heavily sclerotized rather than having the small, isolated sclerites characteristic of the other members of this species group.
