Less mites, species groups, , than one-third (48) of the Mexican Tenuipalpidae, Tenuipalpinae. tenuipalpids are distributed in 8 genera (Aegyptobia, Dolichotetranychus, Pentamerismus, Phytoptipalpus, Priscapalpus, Pseudoleptus, , and Ultratenuipalpus), and over two-thirds (117) are in the genus . Also included are keys to subfamilies, genera, species groups, and species; descriptions, figures, host , and distribution data for each species; and list of Mexican species and their host plants. The fauna is examined principally by analysis of the morphological characters, distribution, and host plants, and an introduction to the classification of the neotropical Tenuipalpidae is outlined.

The following species groups and subgroups are established under each subfamily and genus: Brevipalpinae: Aegyptobia - macswaini and tragardhi groups; Brevipalpus - californicus, cuneatus, frankeniae, obovatus, phoenicis, and portalis groups; Dolichotetranychus - carnea, floridanus, and summersi groups; Pentamerismus - erythreus and oregonensis groups; Phytoptipalpus - cercidium and paradoxus groups; Priscapalpus - macropilis group; Tenuipalpinae: Tenuipalpus - caudatus group (annonae, anoplus, and bakeri subgroups) and proteae group; and Ultratenuipalpus - meekeri and younguisti groups.

Nomenclatural changes are as follows: Brevipalpus solanum Baker, Tuttie, and Abbatiello and B. incanum Baker, Tuttle, and Abbatiello are junior CONTENTS

Other specimens were by Edward W. Baker and Donald M. taken on plant material intercepted at Tuttlei/ quarantine stations along the Mexican-American border. The plant feeding tenuipalpids, or false spider mites, are widely Tenuipalpids may be collected either distributed and more numerous in by (1) visual examination of the warmer regions of the world.
