Syndesus ambericus is an extinct species of stag beetles in the subfamily Syndesinae known from a single possibly Miocene[1][2] fossil found on Hispaniola.

[3] 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 holotype amber specimen, number 502873, is currently housed in the Department of Paleobiology in the National Museum of Natural History in Washington, D.C.

Woodruff's 2009 type description of the new species was published in the entomology systematics journal Insecta Mundi.
