Original description Diagnosis: Coiling similar to Globivalvulina, with few whorls and few chambers in each whorl, with a tendency of the increasing of the width of the chambers during the growth. Septa strongly curvated backward. Chambers relatively rectangular in axial section. Wall single layered, microgranular.
Occurrence: Questionable in early Murgabian of Thailand (UENO & SAKAGAMI, 1993; in our opinion, it is Midian). Murgabian-Dzhulfian-Dorashamian of southern Turkey (e.g. CANUTI et al., 1970 updated by GAILLOT, 2006; KOYLÜOGLU & ALTINER, 1989; ÜNAL et al., 2003), Thailand and Malaysia (YANAGIDA et al., 1988; FONTAINE et al., 1993, 1994). Midian of Batain Plain, Oman (VACHARD et al., 2002). Earliest Midian-earliest Dzhulfian of Transcaucasia (KOTLYAR et al., 1989; G. & M. NESTELL, personal communication, 2007). Midian of New Zealand (VACHARD & FERRIÈRE, 1991). Late Midian of central Japan (KOBAYASHI, 2006b). Dorashamian of Greece (ALTINER & ÖZKAN-ALTINER, 1998; BAUD et al., 1991; GRANT et al., 1991). Wuchiapingian-Changhsingian of southern China (LIN et al., 1990). Wuchiapingian of northern Italy and Iran (MOHTAT-AGHAI & VACHARD, 2005). Duhaysan Member of eponymic Khuff Formation in Saudi Arabia (VACHARD et al., 2005). Changhsingian of Hungary (THÉRY et al., 2007).
