The worm fauna from the Lower Callovian (Middle Jurassic) of La Voulte-sur-Rhône (Anleche, France) is described through the recognition of two new genera and five new species of polychaete annelids: the arenicoloidean Jubarenicola jischeri n gen n. sp .. and the aphroditoideans Paleoaphrodite gallica n. sp, Paleoaphrodite briggsiana n sp, Paleoaphrodite adeliae n. sp. and Protopholoe rhodanitidis n. gen. n. sp. Moreover, Rondeletia scutata n. gen n sp is the third sipunculan species recorded within Mesozoic, Megaderaion callovianum n sp. is the third fossil enteropneust species known. Since the soft tissues o fthese woms show different degrees of pyritization, some considerations about the La Voulte-sur- Rhône paleoenviroment are proposed.
