Abstract
Background: Although the colonial flagellate alga Anthophysa vegetans is well known in Europe, it has only been recorded from Africa (Nigeria) once. It was recently found in the Mooi River, South Africa – making this a first record of the presence of A. vegetans in southern Africa. Objectives: The objective of this study is to record a new geographic locality for A. vegetans for South Africa. Method: Light microscopy was used to compare morphological features of the species found in South Africa with illustrations and literature on A. vegetans found in Europe and other countries of the world. An extensive literature survey was done to determine the species’ current geographic distribution. Results: A. vegetans is widely distributed across all continents, except Africa and Antarctica. During this study, it was described from a new location in the Mooi River near Potchefstroom in the North West province, South Africa, making this a first record of its presence in southern Africa. Conclusion: The known geographic distribution of A. vegetans was expanded to include southern Africa and, to be more specific, South Africa.
Highlights
During 1702, Antonie van Leeuwenhoek first observed the colourless, flagellate colonial algal genus Anthophysa Bory de Saint-Vincent 1822 (Dobell 1932)
At the same time as introducing this new genus, Bory de Saint-Vincent (1822) changed the specific name from vegetans to muelleri in honour of Müller
According to Belcher and Swale (1972) A. vegetans is widely distributed, and literature searches revealed its presence in the freshwaters of most continents, including Europe, Asia, North and South America, and Australia (Figure 1)
Summary
The colonial flagellate alga Anthophysa vegetans is well known in Europe, it has only been recorded from Africa (Nigeria) once. It was recently found in the Mooi River, South Africa – making this a first record of the presence of A. vegetans in southern Africa
