Italogesina transita Kozur, 1985b: 17 , pl. 3, figs 9-11. — Gerry et al. 1987: 206, pl. 2, fig. 20.

Sargentina transita – Crasquin-Soleau et al. 1999: pl. 3, figs 5-8;2005: pl. 4, figs 4.1-4.7. — Honigstein et al. 2005: 409, 419, pl. 2, fig. 13.

MATERIAL EXAMINED. — Three complete carapaces, MNHN.F. F72183 , two specimens without barcode.

OCCURRENCES. — Early Lopingian of Bükk Mountains, Hungary ( Kozur 1985b), Lopingian of Israel ( Gerry et al. 1987; Honigstein et al. 2005); Guadalupian of Sultanate of Oman ( Crasquin-Soleau et al. 1999); Guadalupian of Saudi Arabia ( Crasquin-Soleau et al. 2005). Khachik Formation Unit VI (samples A. 176, A. 204 and A. 210), Guadalupian, Ali-Bashi section, Iran (this study).

DIMENSIONS. — L = 79.5 µm; H = 48.6 µm; H/L = 0.61.

DESCRIPTION

The specimens are attributed to Sargentina transita ( Kozur 1985b) in regards of their sub-rectangular carapace, the slight overlap of LV on RV and sulcus (S2) shallow for the genus. The figured specimen could be a female due to the rounder and large posterior part of the carapace.
