Sepidiini
The Sepidiini is a tribe of ground-dwelling darkling beetles (Tenebrionidae), that occurs across Africa, the Mediterranean Basin, the Arabian Peninsula and Mesopotamia. It is composed of many hundreds of species. The larvae of some species are known to damage crops. Morphology Their morphology is complex due to their richly divergent forms. They are distinguished from the diurnal taxa, by their well-developed and true hypomera of the elytra, the free mobility of the thorax and hind body, and the free and non-fused pleurital and pleural margins of the sterna and elytra respectively. Biology Their morphology is believed to facilitate moisture absorption and accumulation, via the open body sutures and the loosely joined body parts. Subtribe Trachynotina excepting, they show an almost uniform tendency to be nocturnal, crepuscular or shade-loving. Like the tribe Tentyriini, their daily rhythm is based on a strictly nocturnal ancestral disposition. Their open and non-connate body ...

Trachynotina
Trachynotina is a subtribe of darkling beetles in the family Tenebrionidae Darkling beetle is the common name for members of the beetle family Tenebrionidae, comprising over 20,000 species in a cosmopolitan distribution. Taxonomy ''Tenebrio'' is the Latin generic name that Carl Linnaeus assigned to some flour beetles .... There are about 10 genera and more than 170 described species in Trachynotina, found in southern Africa. Although Sepidiini species attract the attention of enthusiasts due to their outstanding morphology and behaviour, the group lacks comprehensive revisions at all taxonomic levels. Genera These 10 genera belong to the subtribe Trachynotina: * '' Cyrtoderes'' Dejean, 1834 * '' Epairopsis'' Koch, 1955 * '' Ethmus'' Haag-Rutenberg-Rutenberg, 1873 * '' Histrionotus'' Koch, 1955 * '' Microphligra'' Koch, 1955 * '' Ossiporis'' Pascoe, 1866 * '' Oxycerus'' Koch, 1955 * '' Somaticus'' Hope, 1840 * '' Trachynotus'' Latreille, 1828 * '' Trichethmus'' Gebien, 1937 ...
