On some peri-mediterranean lower cretaceous dasyclad species (Calcareous algae; Dasycladales) previously assigned to different genera

Abstract

The taxonomic position of some dasyclad species which were previously assigned to the same taxon or, alternatively, were assigned to different genera by different authors, is discussed and revised, respectively. The material described and figured as Cylindroporella lyrata MASSE & LUPERTO-SINNI is shown to be heterogeneous (also partly described as Salpingoporella robusta SOKAČ) and some figured sections are shown to possess new characteristic features. These forms are therefore singled out and described as Biokoviella n.gen. with two species: B. robusta (SOKAČ) n.comb. and B. gusici n.sp. Macroporella aptiensis SOKAČ is shown to represent the infertile (sterile) forms of Neomeris cretacea STEINMANN and, consequently, has to be regarded as the younger objective synonym of the latter. New material, with clearly visible morphological characteristics, has enabled the "resurrection" of the controversial genus Korkyrella SOKAČ & VELIC ́, 1981, and its species, K. texana (JOHNSON), which was originally invalidly described.
