Nanocaecus hlavaci gen. & sp. nov. from Socotra Island is described and figured by SEM. It is the first record of the tenebrionid tribe Gnathidiini, subtribe Anopidiina from the Socotra Archipelago. The closest relatives (genera Anopidium Jeannel & Paulian, 1945, Paranopidium Dajoz, 1973) live in subterranean habitats of the mountains in eastern Africa. The new genus is very probably an old continental relict element in the island fauna. A key to the genera of the subtribe Anopidiina from Africa including Madagascar, Mauritius, Seychelles and Socotra is provided and a catalogue of the tribe Gnathidiini from that area is added.
