Early Miocene luidiid asteroids (Echinodermata, Asteroidea) from Winterswijk-Miste (The Netherlands)

Dissociated ossicles (inferomarginals, ambulacrals and adambulacrals) of luidiid asteroids (Luidiidae) from early Miocene Hemmoorian (Oxlundian) strata at Winterswijk-Miste (province of Gelderland, The Netherlands) are illustrated and briefly described. The material is compared with contemporary Luidia ciliaris (Philippi, 1837), but, for the time being, left in open nomenclature. It may represent a new subspecies or forma within the Ciliaris Group (sensu Döderlein, 1920) of the genus Luidia Forbes, 1839. The present occurrence appears to be stratigraphically older than records of Miocene luidiids from central Poland.
