An ostracod fauna from the upper Langport Member (Penarth Group: Rhaetian, Upper Triassic) near Watchet, west Somerset (UK), including two new species of Eucytherura and Cytherelloidea praepulchella n. nom.

Abstract. An abundant ostracod fauna consisting of just five species is described from the upper part of the Langport Member of the Lilstock Formation of the Penarth Group (Rhaetian, Late Triassic) near Watchet, west Somerset. The fauna is dominated by Ogmoconchella bristolensis (Anderson) and Cytherella plattensis Anderson. The only other ostracods present are two new species of Eucytherura, and a form previously identified as Cytherelloidea pulchella Apostolescu or Cytherelloidea cf. pulchella, which is here revised and renamed Cytherelloidea praepulchella.
