Abstract

We present the first records of Leptestheria brevirostris since its discovery in Namibia by Barnard in 1924. Our records come from Botswana and South Africa, and present significant range extensions. We redescribe L. brevirostris according to modern standards and present the first description of the male. We also discovered that L. brevirostris is likely a rock pool specialist, specific to sandstone and gneiss outcrops; this is the first record of a rock pool specialist clam shrimp from Africa and the second rock pool specialist described for Leptestheriidae. Finally, we depict and discuss the validity and usefulness of diagnostic characters for Leptestheria species in southern Africa, especially the usefulness of carapace interval ornamentation.

摘要

我们报告了自 1924 年 Barnard 在纳米比亚发现短颈沼虾以来的首个记录。我们的记录来自博茨瓦纳和南非，展示了显著的分布范围扩展。我们根据现代标准重新描述了短颈沼虾，并首次描述了雄性个体。我们还发现短颈沼虾可能是一种石滩专性物种，仅限于砂岩和片麻岩露头；这是非洲首次记录石滩专性淡水枝角类，也是 Leptestheriidae 描述的第二种石滩专性物种。最后，我们描述和讨论了南非 Leptestheria 物种的鉴别特征的有效性和实用性，特别是甲壳间隔装饰的实用性。
