Material. Two specimens: one in OZ838, another one in OZ834.
Dimensions. Length 186 µm, diameter 83-98 µm.
Remarks. In Dumitrică et al. ( 1997), by a mistake, the species is mentioned as Loopus blabla in the text, whereas on the plate it is mentioned as Loopus nudus . Both species seem to be synonymous, one is viewed under electronic microscope, the other under light microscope. The specimens from the upper Valanginian of Sardinia differ from those from Oman (Dumitrică et al., 1997) in having a smooth surface, less inflate shell and more segments.
Range. Early Valanginian to late Barremian (Baumgartner et al., 1995).
