ephemeral waterbodies of southern Africa are regarded a global hotspot
for large Branchiopod diversity. Although the distributions and
systematics of Anostraca and Notostraca have been fairly well defined,
clam shrimps have received much less attention. So far, 18 clam shrimp
species are known from the sub-region, but none of the available
published literature defines their distribution in South Africa.
Furthermore, most of the recent studies were concentrated in the mesic
provinces, while very little information is available from the Northern
Cape, where most ephemeral waterbodies in the country occur. This study
reviews the distribution of clam shrimps in South Africa by reviewing
published distribution records and contributing novel data from surveys
in the Northern Cape. We found that 13 of the 18 species from the
sub-region occur in South Africa, of which four are restricted to their
respective provinces. We further clarify the current state of endemism
patterns in South Africa and provide novel findings from the Northern
Cape, including three new range extensions. The Northern Cape hosts the
highest species richness, with nine species, followed by the Eastern
Cape, where seven species have been recorded so far. Most other
provinces have low species richness and endemism, while no species
records have been published from the Limpopo province yet. Surveys over
large geographical scales are important, and more research is needed on
clam shrimp systematics in South Africa.
Key words: Wetlands, Ephemeral,
Endemism, Richness, Branchiopoda.
