摘要

The ephemeral waterbodies of southern Africa are regarded a global hotspot for largeBranchiopod diversity. Although the distributions and systematics of Anostraca andNotostraca 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 availablepublished literature defines their distribution in South Africa. Furthermore, most of therecent studies were concentrated in the mesic provinces, while very little information isavailable 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 publisheddistribution records and contributing novel data from surveys in the Northern Cape. Wefound that 13 of the 18 species from the sub-region occur in South Africa, of which fourare restricted to their respective provinces. We further clarify the current state ofendemism patterns in South Africa and provide novel findings from the Northern Cape,including three new range extensions. The Northern Cape hosts the highest speciesrichness, with nine species, followed by the Eastern Cape, where seven species have beenrecorded so far. Most other provinces have low species richness and endemism, while nospecies records have been published from the Limpopo province yet. Surveys over largegeographical scales are important, and more research is needed on clam shrimp systematicsin South Africa.
