Syndesus ambericus
''Syndesus ambericus'' is an extinct species of stag beetle in the family Lucanidae known from a single possibly Miocene fossil found on Hispaniola. ''S. ambericus'' is the first species of stag beetle to have been described from fossils found in Dominican amber and is one of four species from amber, and the only stag beetle species known from the Caribbean.
==History and classification==
''Syndesus ambericus'' is known from a single fossil insect which is an inclusion in a transparent chunk of Dominican amber. The amber was produced by the extinct ''Hymenaea protera'', which formerly grew on Hispaniola, across northern South America and up to southern Mexico. The fossil was first noted as interesting in 1983 in a private amber collection in the Dominican Republic. It was subsequently reported as an unidentified lucanid in a 1992 paper. Between the first examination in 1983 and reexamination of the fossil in 1998 the fossil was broken and subsequently repaired. The holotype amber specimen, number 502873, is currently housed in the Department of Paleobiology in the National Museum of Natural History in Washington, D.C.. The holotype fossil is composed of a complete adult individual that was collected from an amber mine, possibly the Palo Quemado mine, in fossil bearing rocks of the Cordillera Septentrional mountains, northern Dominican Republic.〔〔 The amber dates from at least the Burdigalian stage of the Miocene, based on studying the associated fossil foraminifera and may be as old as the Middle Eocene, based on the associated fossil coccoliths. This age range due to the host rock being secondary deposits for the amber and the Miocene the age range is only the youngest that it might be.〔 The fossil was examined by entomologist Robert E. Woodruff of the Florida State Collection of Arthropods. Woodruff's 2009 type description of the new species was published in the entomology systematics journal ''Insecta Mundi''. The specific epithet ''ambericus'' is in recognition of the amber mining company Amberica, which has helped to bring notable amber fossils to the attention of paleontologists.〔
