T1  - Discometra luberonensis sp. nov. (Crinoidea, Himerometridae), a new feather star from the Late Burdigalian
T2  - European journal of taxonomy
N2  - Most fossil feather stars are known only from the centrodorsal often connected to the radial circlet.  This  is  the  case  for  Discometra  rhodanica  (Fontannes,  1877),  the  type  species  of  the  genus  Discometra, collected from the Late Burdigalian of the Miocene Rhône-Provence basin (southeastern France).  The  quarries  operating  in  this  area  have  exposed  layers  from  the  Late  Burdigalian  on  the  northern fl ank of the Lubéron anticline near Ménerbes (basin of Apt, Vaucluse, southeastern France). These  layers  contain  exceptionally  well-preserved  echinoderms,  among  which  are  three  specimens  of  a  feather  star  with  cirri  and  arms  still  connected  to  the  centrodorsal.  They  are  attributed  to  a  new  species: Discometraluberonensis sp. nov. (Himerometridae). The number of arms can reach 60, as in extant species of the genus Himerometra, but the pattern of arm divisions is closer to that of the genus Heterometra, which has no more than 45 arms in extant species. Discometra luberonensis sp. nov. diff ers from D. rhodanica by the characters of its centrodorsal. Here we redescribe the centrodorsal and radial circlets of D. rhodanica based on previously and newly collected specimens. We designate a neotype for D. rhodanica, because the holotype is considered lost. Affi  nities between Discometra, Himerometraand Heterometra are discussed.
