| Zonariophila semiendophytica is described as a new genus and species from the coast of the East Cape, South Africa. It is characterized by a single large elongate basal cell immersed in the thallus of Zonaria subarticulata (Lamour.) Papenf.; this laterally compressed cell gives rise, on both edges, to several short (up to 2.5 mm), uncorticated, erect, sparingly branched filaments. The position and structure of the procarp (the subapical cell in a determinate female fertile filament bears two sterile pericentral cells and one fertile pericentral cell, the latter with one sterile cell and a four-celled carpogonial filament), and the development of a single involucral filament from the hypogenous cell, put this genus in the immediate vicinity of... |

| After studying the holotype of Engina schrammi Crosse, 1863, it became evident that the genus Risomurex Olsson & McGinty, 1958, is based on misidentified shells. Material recently collected at the Caribbean coast of Costa Rica included a new species, Risomurex mosquitensis, which is prefered to be considered the type-species of Risomurex. Relations with congeneric species are discussed. St. Thomas is designated type-locality for Ricinula rosea Reeve, 1846. |
