Abstract
Sixteen geographical strains from Europe and North America were used in testing degrees of relationships among the various components of the species complex. Matings were made between the various green strains, between green and red, and between the several red strains. Results indicate lack of conspecificity between the European Tetranychus telarius (L.) and the American T. bimaculatus Harvey. In Europe, the red members of the complex include at least one British and one Continental species, and the same is true of the green ones. Pending a study of the synonymy, the European red forms are left under T. cinnabarinus (Boisd.), the green ones under T. telarius. On the North American continent, T. bimaculatus is divided into an eastern onymotypic subspecies and a new Pacific Coast subspecies, T. b. occidentalis. The so-called “red phase” is found to include two previously described species, T. multisetis McG. (California) and T. lobosus Boudr. (Louisiana and Texas), as well as two new species, T. marylandicus (Maryland) and T. australis (Texas to Mississippi). The aedeagus of each species is figured.
