Two New Species of the Tribe Tesserocerini (Coleoptera: Platypodidae) from Miocene Ethiopian Amber
Abstract
Two new species of ambrosia beetles (Coleoptera: Platypodidae), one from the genus Cenocephalus Chapuis, 1865 and the other from Chaetastus Nunberg, 1953, are described from Miocene Ethiopian amber found near Alem Ketema. Cenocephalus josephi sp. nov. is similar to C. lalolaensis Nunberg, 1963 but differs based on its larger, brownish-black body, a weakly convex interstriae and a very wide metepisternum. Chaetastus samsockorum sp. nov. is similar to Ch. persimilis (Schedl, 1933) but is distinguished by a smaller body, narrower pronotum, shorter elytra and an elytral declivity that is not granulate. This is the first time the genus Chaetastus has been found in the fossil record, as well as the first documentation of the genus Cenocephalus from the Miocene of Africa. A key to Platypodidae from Ethiopian amber is provided.
期刊介绍:
Paleontological Journal (Paleontologicheskii zhurnal) is the principal Russian periodical in paleontology. The journal publishes original work on the anatomy, morphology, and taxonomy of fossil organisms, as well as their distribution, ecology, and origin. It also publishes studies on the evolution of organisms, ecosystems, and the biosphere and provides invaluable information on global biostratigraphy with an emphasis on Eastern Europe and Asia.
