Metacuvillierinella sireli Fleury & Özkan, 2020
Description Metacuvillierinella sireli n. sp., mainly A tests. 1-14: Centered axial sections. The initial coiling of some tests (3-4, 9, 13-14) is almost perfectly planispiral, but others (1-2, 5-8, 11-14) show various aspects of the first coils that, as well as faintly twisted overall profile, testify the persisting streptospiral tendency (pseudoplanispiral coiling). Note the flexostyle in 3, 9, 12, and 14; the first layer of primary chamberlets is already present in the first coil. 15-19: Off centered sections displaying the overall twisted profile of sigmoid type (16, and 18-19 could be B tests). 20-22, 24: Centered equatorial sections. Poor preservation of the tests prevents detailed observations but the flexostyle is well observable in 20-21 and 22; the succession of 2 chambers with preseptal space is clear in 20 (next to last coil, south-west of the proloculus); 24: usual aspect of this type of section, partly hidden by micritization. 23: Off centered section of which the central coil shows a preseptal space crossed by thin probable preseptal pillars; they are much larger in last chamber (see also 20, last coil, south-east of the proloculus). Scale bars: 1mm. (From Fleury and Özkan, 2020)
