The following suggestions in use of family-group names for eriophyoid mites are made in accordance with the International Code of Zoological Nomenclature. (1) The name Sierraphytoptidae Keifer 1944 should have priority over Nalepellidae Roivainen 1953 sensu Newkirk and Keifer (1971). (2) The name Diptilomiopidae Keifer 1944 should have priority over Rhyncaphytoptidae Roivainen 1953 sensu Keifer (1961). (3) The superfamily concept of Shevchenko (1968, 1971) should take the name Nalepelloidea Roivainen 1953 rather than Trisetacoidea (a justified emendation of "Trisetoidea") Shevchenko 1968. (4) The names Nalepellidae and Nalepellini should take Roivainen 1953 as author rather than Newkirk and Keifer (1971). (5) Similarly, the names Sierraphytoptini Keifer 1944, Mackiellini Keifer 1946, Diptilomiopinae Keifer 1944, and Trisetacini Shevchenko 1968 should retain their authors and dates as first proposed for new family-group taxa, rather than being new taxa as proposed by Newkirk and Keifer (1971).
