Cuvillierinella perisalentina Fleury, 2016
Description Cuvillierinella perisalentina. 1–12: centered (except 8) sections of A tests displaying the various modes of coiling. 2–3, 6–7, 9–10 and 12 appear planispiral or nearly throughout; section 1 (holotype) is axial around the proloculus and equatorial in adult stage; section 4 is axial around the proloculus, becomes equatorial, then axial in the last whorl; 5 is nearly equatorial in the young and axial in the adult; sections 4 and 11 present a twisted aspect revealing the irregular mode of coiling. Note the very early cloisonnettes in every axial section. Note the openings, clearly visible in two sections: on 2, the rectangle shows them off, the primary one being oblique to the orientation of chamberlets; on 10, downwards, the secondary ones interrupt the septum and are related to the chamberlets of next chamber. 8: section through a chamber of an UUT. The secondary chamberlets are scattered in a massive endoskeleton like in sections 4 and 10–12. The preseptal pillars are thick, tending to hide the preseptal space in equatorial sections (A and B tests); they are obvious in some axial sections (6, 10 and 17). 13–17: B tests, built around a very small proloculus and a tiny streptospiral young part (13b, 17); the involute adults resemble the A tests but are larger and followed by a large pseudoevolute terminal flange; the overall aspect is not far from B tests of C. salentina and C. aff. pylosensis, but the involute part is larger (see Fig. 14); 13b (enlarged central part of 13) and 17 (probably immature) show the miliolid-like nepionic stage. Scale bars = 1 mm, but 13b = 0, 25 mm. The figured sections are included in thin slices deposited in the paleontological collections of the University of Lille, Sciences and Technologies under the following numbers. Fig. 1: USTL 3057; Fig. 2, 7 and 9: USTL 3058; Fig. 3–5: USTL 3059 to USTL 3061; Fig. 8–17: USTL 3062 to USTL 70, successively. (From Fleury, 2016)
