Annotated list of centipedes in Mexican amber

Centipedes (Myriapoda: Chilopoda) are among the earliest terrestrial arthropods to have colonized the continents, with their fossil records dating back to the late Paleozoic. In Mexico, the fossil record of centipedes is exclusively found in the amber deposits of Chiapas, located in the southern region of the country. These deposits are estimated to have originated from the late Oligocene to the early Miocene boundary, corresponding to a period of approximately 24 to 20 million years ago. We present an updated compilation of centipedes identified in Mexican amber. This report encompasses 22 amber inclusions, including 13 newly documented records across four orders, six families, and one genus. The order Geophilomorpha is the most represented, followed by Scolopendromorpha, Scutigeromorpha, and Lithobiomorpha. The new records belong to the families Henicopidae (Lithobiomorpha), Scutigeridae (Scutigeromorpha), and Schendylidae (Geophilomorpha). This inventory underscores the critical role of amber deposits in enhancing our understanding and documentation of Chilopoda diversity throughout geological history.
