Description Description: First whorls more or less planispirally coiled with endothyroid chambers. Adult whorls uncoiled, biseriate. Wall brownish, granular. Occurrence: The oldest specimens of this genus rarely appear in the early Serpukhovian of the Montagne Noire, southern France (where they seem to be endemic: Pille, 2008; Vachard et al., 2016b) and late Serpukhovian of the Pyrenees, and Tian-Shan (Kulagina et al., 1992, re-interpreted by Vachard et al., 2013a). Then, Spireitlina becomes relatively common and cosmopolitan from the Bashkirian to the Wordian (Vachard et al., 2013a), and rare in the Capitanian of Italy, Crimea, Iran, Japan and Texas (Vachard & Miconnet, 1990; Ueno, 1992b; Pronina & Nestell, 1997; Nestell et al., 2006; Kobayashi, 2012, 2016; Vachard in Kolodka et al., 2012; Vachard, 2016a).
