(Fig. 14 J–N)

cf. Worthenia pagoda Mansuy, 1912: 39, pl. 7, fig. 6; Delpey, 1941: 353, fig. 26.

Material. Two specimens: ESKU-19- LP 17, 66.

Dimensions (mm): ESKU-19- LP 17: height = c. 6.6; width = 4.9. ESKU-19- LP 66: height = 5.5; width = c. 5.0; apical angle = 75º.

Description. Shell moderately high-spired, trochiform, consisting of 6 whorls; first three teleoconch whorls smooth, convex, rounded; mid angulation develops starting from the 4th whorl onward; the last quarter of the last whorl slightly deflected; suture slightly impressed; subsutural ramp with faint subsutural convexity, slightly concave on remaining part; ramp inclining at an angle of about 45–60°; subsutural ramp ornamented with three spiral ribs starting from 4th whorl and almost straight prosocline growth lines; spiral ribs ornamented with equally spaced nodes; mid-angulation forms periphery where selenizone situated; selenizone prominent, wide, comprising about 1/7 of the whole whorl face of 5th whorl, ornamented with equally spaced strong nodes, bordered by fine spiral ribs; lower whorl face facing abapically, concave, ornamented with two nodular spiral ribs; lowest spiral rib stronger, situated at angulation, forming basal edge; base convex, ornamented by several evenly spaced nodular spiral ribs, narrowly phaneromphalous; aperture unknown.

Remarks. We tentatively assign the studied specimens to Worthenia pagoda, based on the whorl profile, the presence of three nodular spiral ribs on the upper whorl face and the nodular selenizone. Species with a similar whorl profile belonging to Worthenia are more common in the Triassic e.g., W. annamensis Mansuy, 1913 b from Tonkin, Vietnam but are very rare in the Permian. W.? psiche (Gemmellaro, 1889) from the Permian of Italy has a similar shape but have only two spiral ribs on the upper whorl face.
