On the type species of Aubignyna and a description of A-hamblensis, a new microforaminifer from temperate shallow waters

The genus Aubignyna Margerel, 1970 (type A. mariei) was originally describe d from the upper Pliocene of NW France. Examination and re-illustration of topotypes of A. mariei Margerel, 1970, the holotype of Buccella planidorso Atkinson, 1969 (from the Recent of Cardigan Bay, Wales) and syntypes of Rot alia perlucida Heron-Allen & Earland, 1913 (from the Glare Island Survey, w estern Ireland) shows them to be conspecific. Consequently, the type specie s of Aubignyna becomes R. perlucida, for which a lectotype is chosen. A new species of microforaminifera formally described here is assigned to Aubign yna and shown to occur in a wide range of intertidal-shallow subtidal, brac kish-normal marine estuaries and lagoons in Europe and North America.
