Abstract: 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.
