Abstract

The tiny, slender, bright-red false spider mites of the genus Dolichotetranychus Sayed are widely distributed over the world. Though so similar morphologically that some recent students have regarded specimens from various hosts as representing a single species, this study indicates that the genus contains at least ten distinct species, including four new ones and one new combination:

Dolichotetranychus carnea (Banks)

(Stigmaeodes cinctus Ewing)

Dolichotetranychus micidus, new species

Dolichotetranychus ancistrus, new species

Dolichotetranychus salinas Pritchard and Baker

Dolichotetranychus summersi Pritchard and Baker

Dolichotetranychus vandergooti (Oudemans)

Dolichotetranychus macer, new species

Dolichotetranychus floridanus (Banks)

Dolichotetranychus australianus (Womersley), new combination

Dolichotetranychus apaches, new species

The species are described and illustrated, and the distinctive characters are pointed out. Keys are given for distinguishing the males of all ten species and the females of all but two, which require the males for separation. The hosts of all but one species are monocotyledons, mostly grasses.
