摘要
One new species of Plakolana Bruce, 1993 and three new species of Cirolana Leach (1818), from the Lower Cretaceous (Aptian) Sierra Madre Formation dolomites at El Espinal quarries (Central-East Chiapas, SE Mexico) are reported and described and compared with other fossil species Cirolanidae from around the world. The specimens consist of the body and a few moults, with showing various degrees of decay but most of them with preserved taxonomic features, including mandibles, pereonites, pereopods, pleonites, pleotelson and uropods. This is the third report of fossil marine or estuarine isopods from the Cretaceous of Mexico and the second on the Peracarida of El Espinal quarries, as well as the first record of fossil Cirolana and Plakolana from Mexico.
