A review of the Socotran species of the melolonthine tribe Tanyproctini is provided. In addition to three species previously known from this island, five more including one new genus are described: Canudema homhil sp. nov. is closely related to C. socotrae Lacroix, 1994; both species differ mainly in the shape of antennomeres and external male genitalia. Tanyproctus (Tanyproctus) keithi sp. nov., T (T.) lacroixi sp. nov. and T (T.) wraniki sp. nov. are considered morphologically similar to T (T.) canui Lacroix, 1999 and T (T.) puncticeps (Waterhouse, 1881). Socotraproctus haghier gen. et sp. nov. can be characterized mainly by having considerably small eyes and elytra with longitudinal strips of scale-like shaped, whitish macrosetae. A key to Socotran Tanyproctini species is given along with their diagnostic characters including illustrations of copulatory organs and external morphology. The daily activity pattern of the taxa is discussed.
