REMARKS

In the revision of the original material of Fichtel & Moll deposited in the Vienna Museum ( Austria), Rögl & Hansen (1984) redescribed this species.They designated the lectotype from among 7 specimens and published SEM photographs of it (1984: pl. 23, figs 5, 6). This specimen is registered under number no.MI- 560in the Vienna Museum Collection,and the paralectotypes under no. MI-560/1-6. This lectotype resembles Nonionina boueana by its general outline, the number and the shape of chambers. It differs in the possession of “a system of furrows branching out from the depressed part of the sutures […] Fine striations extend from the aperture to the apertural face” ( Rögl & Hansen 1984: 65).

D’Orbigny had cited this species in the Adriatic and Mediterranean seas (1826: 295, no.23). We have also observed specimens of Nonion fabum from the Pliocene of La Coroncina on which the furrows appear clearly with binocular lens but the apertural striations must be only visible at a higher magnification.
