New genus C – Korn 2025: 57. — Korn & Ghaderi 2025: 7, 61, 63, fig. 33.

Type species

Lutonautilus cratus gen. et sp. nov.

Diagnosis

Genus of the family Pleuronautilidae with subevolute conch; whorl profile inverted trapezoidal, weakly depressed or equidimensional with broadly rounded venter, parallel or weakly convergent flanks, rounded umbilical margin and convex or flattened umbilical wall. Sculpture with ribs on the flanks, without nodes or tubercles. Suture line with very shallow external lobe and broadly rounded lateral lobe; without annular process.

Etymology

Named after the Lut desert (Central Iran), at which margin Baghuk Mountain is located.

Included species

Central Iran (this paper): Lutonautilus cratus gen. et sp. nov., Wuchiapingian; Lutonautilus elachus gen. et sp. nov., Wuchiapingian; Lutonautilus cymus gen. et sp. nov., Wuchiapingian.

Remarks

Lutonautilus gen. nov. is newly introduced here for Permian species with a conch shape and sculpture similar to some Triassic species of Pleuronautilus , such as P. mosis Mojsisovics, 1882 . The main difference, however, is that Lutonautilus does not possess the annular lobe that is present in Pleuronautilus .

Lutonautilus gen. nov. occurs with morphologically similar species in the sections of central Iran and probably also in the Transcaucasian region. But it is also possible that the genus occurs in other regions such as the Salt Range of Pakistan; however, this can only be clarified by revising the corresponding assemblages.
