New records of Trentepohliales (Ulvophyceae, Chlorophyta) from Africa
Rindi, Fabio; Guiry, Michael D. López-Bautista
The diversity and distribution of the Trentepohliales have been investigated in detail in several regions of Europe and Asia. However, the information available for other continents is relatively limited and very little is known for these algae in Africa. New records of Trentepohliales for Africa were obtained in the course of surveys conducted in 2005 in South Africa, Namibia and Tanzania. For Phycopeltis epiphyton, Trentepohlia abietina and Trentepohlia flava, these are the first documented records for the continent. A species of Printzina, probably an undescribed taxon, was collected from trees in Tanzania. The new collections allowed the rediscovery and characterization of some poorly known species, of dubious taxonomic validity, such as Trentepohlia afra and T. chinensis. Additional records of widespread species, such as Phycopeltis arundinacea and Trentepohlia umbrina, were also obtained. The morphology and distribution of the species collected are described and the taxonomic and biogeographical implications of the new records are discussed.
