摘要
The new tribe Mediumiugamiini (Coleoptera: Polyphaga: Tenebrionoidea: Mordellidae) is described based on Mediumiuga sinespinis gen. et sp. nov. It is a fossil beetle from Albian (Early Cretaceous) amber from the Penacerrada I outcrop (Spain). It is the first Spanish beetle described in amber. The mesotibiae and mesotarsi bearing multiple dorsal lateral ridges, running oblique, metatibiae without any dorsal or dorsal lateral ridge, only showing a subapical ridge, and metatibiae without apical spurs, define the new tribe. A key for worldwide tribes of Mordellinae, including Mediumiugamiini, is provided. Evolution of some characters of Mordellidae along Cretaceous is discussed. (C) 2013 Elsevier Ltd.
