A synopsis of the spider beetles (Coleoptera: Ptinidae) of Socotra, with the description of a new genus and two new species

Abstract

The previously known spider beetle fauna of Socotra comprises four endemic species (Mezium erinaceus Belles, Sphaericus hirsutus Belles, Ptinus bertranpetiti Belles, and Silisoptinus inermicollis Belles) and Dignomus mesopotamicus (Pic), which is also known from Arabia and Mesopotamia. The study of new material has resulted in the discovery of a new genus and two new species, and many new localities of the previously known species. Here, a synopsis is presented that brings together all information available on the fauna of spider beetles of the Socotra archipelago, including updated distributions and ecological and biogeographical considerations of all species. http://www.zoobank.org/urn:lsid:zoobank.org:pub:3EB99992-B352-42AD-A33D-C01EF494666C.
