DESCRIPTION
Small microconchs with maximum diameters varying from 25 to 33 mm and strongly evolute coiling (U/D from 0. 42 to 0.45) for the complete Subbetic specimens. The whorl section is subsquare to slightly compressed rectangular, with faintly convex flanks and a ventral area with a keel that is bordered by two more or less developed furrows. The innermost whorls are smooth or only slightly ornamented. Later, usually simple ribs appear, which arise at the base of the umbilical wall; somewhat sigmoid, these become stronger in upper part of the flanks, and some support mid-lateral nodes on intermediate whorls. At the BC end, the ribs weaken but do not vanish completely. The aperture is complex with lateral lappets. The septal suture of the HT is simpler but not preserved in the Subbetic specimens.
REMARKS
“ Pelekodites ” schlumbergeri , which has tubercles or nodes, could correspond as microconch of S. (S.) propinquans , which occurs in equivalent stratigraphic interval “ P. ” macer ( Buckman, 1889) may be the most similar “species” but has a more compressed whorl section, no tuberculate stage, and a venter without ventral sulci. Fontannesia curvata Buckman, 1902 is also similar but is more evolute and has denser and more curvate ribs, which persist up to the BC end and lack tubercles. The tuberculate stage of S. (S.) schlumbergeri and its stratigraphic distribution indicate that this species may in reality be a dimorphic microconch of Sonninia and not of Witchellia .
DISTRIBUTION
The type of “ Sonninia Schlumbergeri ”, the only Haug specimen of this species, comes from the Otoites Sauzei zone (Propinquans Zone), from the Haye forest, near Nancy ( France). In the Atlas Mountains ( Morocco) , this species occurs in the upper part of the Laeviuscula and lower part of the Propinquans zones ( Sadki 1996). In the western part of the Swabian Alb ( Germany), P. cf. schlumbergeri occurs in the Pinguis Subzone (which is equivalent to the Hebridica Subzone of British researchers [ Dietze et al. 2008]) and in Kahlenberg, near Ringsheim (Upper Rhine Valley), in the Laeviuscula Zone, Trigonalis Subzone ( Dietze et al. 2009). This stratigraphic range is occupied by P. schlumbergeri in the Wedelsandstein-Formation in the “Zollernalb” of south-western Germany ( Dietze et al. 2019). In the Subbetic, S. (S.) schlumbergeri occurs in the Laeviuscula Zone (Laeviuscula Subzone) and in the Propinquans Zone (Patella Subzone) of Sierra de Alta Coloma area (sections JAC3, JAC4, JAC11, JAC13, JAC22 and JAQ1; Jaén Province).
