Zittelina? arumaensis (Okla 1995) nov. comb., and Suppiluliumaella tarburensis n. sp. (Dasycladales) from the upper Maastrichtian of Iran

The species Salpingoporella arumaensis Okla, 1995 was so far only reported from its type-locality, the Campanian?-Maastrichtian of Saudi Arabia. It is here reported for the first time from the upper Maastrichtian of the Tarbur Formation, Zagros Zone, SW Iran. It is taxonomically discussed and with some reservation newly combined as Zittelina ? arumaensis (Okla). Suppiluliumaella tarburensis n. sp. is a small to medium-sized species of the genus characterized by a comparably small number of close-set laterals of two orders typical for the genus. It represents the youngest representative of the genus described so far. The new discoveries contribute to a better knowledge of the so far poorly known microflora of the Tarbur Formation of Iran. Z. ? arumaensis might be an endemic taxon like Pseudocymopolia anadyomenea (Elliott) or Cymopolia eochoristosporica Elliott, restricted to the Arabian Plate and Tibet.
