Anbarrhacus

''Anbarrhacus'' is an extinct genus of millipede in the family Platyrhacidae known from a fossil found in North America. There is one described species in the genus, ''Anbarrhacus adamantis'', which is one of three millipedes described from Mexican amber.〔〔
==History and classification==
''Anbarrhacus adamantis'' was described from a solitary fossil, which is preserved as an inclusion in a transparent chunk of Mexican amber. At the time of description, the amber specimen was housed in the fossil collection of the Instituto Nacional de Antropología e Historia in San Cristóbal de las Casas, Simojovel. The holotype fossil is composed of a very complete immature male recovered from the Guadalupe Victoria site.〔 Mexican amber is recovered from fossil bearing rocks in the Simojovel region of Chiapas, Mexico. The amber dates from between 23 million years old at the oldest and 15 million years at the youngest. The Guadalupe Victoria site is an outcrop of amber bearing strata belonging to both the Mazantic Shale and Balumtum Sandstone. The deposits preserve a transitional river or stream environments near the coast and preserves fossils of a mangrove forest ecosystem.
The holotype was first studied by a team of researchers headed by Francisco Riquelme of the Universidad Autónoma del Estado de Morelos with their 2014 type description of the genus and species being published in the natural sciences journal ''PLOS One''. The genus name is a derived from a combination of the Arabic voice word ''ánbar'' for "amber" and ''rhacus'', which is used frequently as a genus suffix in the family Platyrhacidae. The specific epithet ''adamantis'' was coined from the Latin word ''adamantus'' meaning diamond, a reference to the pattering on the tops of the collum and metatergites.〔
''A. adamantis'' is one of three millipede species described from Mexican amber, the others being ''Maatidesmus paachtun'' and ''Parastemmiulus elektron'', while a number of other species have been described from the similarly aged Dominican amber.〔〔
