Abstract
For several years the author has been engaged in a study of the predacious mites of value in controlling the European red mite, Metatetranychus ulmi (Koch), in southeastern England. During this time, extensive collections of mites of the subfamily Phytoseiinae were made and several new species found. These are described here.New species of Phytoseiinae have usually been described from female specimens only; the males have been frequently unknown. It is essential in ecological investigations to be familiar with both mature forms. During this study the males of some species of which the females had been described were collected and reared. Some of these have been described elsewhere (Chant, in preparation) and in this paper the male of Typhlodromus bakeri (Garman), 1948, is dealt with.
