Abstract
In this taxonomic study 17 species of tetranychoid mites are recorded from the Cameroun. The following 6 new species are described and figured here: Neotetranychus decorus, Eotetranychus camerounensis, E. hellei, Oligonychus comptus, Tenuipalpus garciniae and T. raphiae. A key to the tetranychoid mites of the Cameroun is given together with biological data and chromosome numbers for each species. Similar information is also given for 4 tetranychid species for which no males were collected.
