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.
