Abstract

The ungdarellaceans form a prolific group of red algae that have a worldwide distribution and are a major component of shallow-marine carbonates. The rare Urtasimella is encountered in great number at the late Visean Valdemilano section (Pedroches basin, southwestern Spain). The genus remained a nomen nudum for fourteen years, but was recently formally proposed by Chuvashov and Anfimov (2007). It is characterized by a poorly differentiated hypothallus. The Spanish material is composed of numerous Urtasimella parallela (Kulik, 1973) comb. nov., a species recognized by the proliferation of perithallic cells.
