Two new Cypridopsinae ostracods, and are described. Both were found only as asexual (all-female) populations in temporary waters of southern Africa. was collected from a small pan in the North-West Province of South Africa. It is approximately 0.5 mm long and belongs to the species group with long swimming setae on the second antennae. However, the species has a somewhat isolated position in the genus owing to the conspicuously reticulated carapace, which is furthermore densely covered by prominent conuli with normal pores carrying long sensilla, as well as to the wide anterior and posterior flanges on the left valve. To allow identification of the new species in relation to its closest congeners, a key to the species of the genus Brady, 1870 from southern Africa is provided. The genus McKenzie, 1977 mostly has an Afrotropical distribution with only few species occurring in other regions. was collected from floodplains of the outskirts of the Okavango Delta in Botswana. It is approximately 0.4 mm long and can be distinguished from congeners mainly by the smaller and more oval-shaped valves. We conclude that southern African Cypridopsinae urgently need integrated taxonomic revision, by means of both morphological characters and DNA-sequence data.
描述了两种新的Cypridopsinae介形虫，即 和 。这两种介形虫均仅在南部非洲的临时水域中以无性（全雌性）种群形式被发现。 采自南非西北省的一个小水洼。它体长约0.5毫米，属于第二触角上有长游泳刚毛的物种组。然而，由于其背甲有明显的网状结构，且左瓣上有宽的前后边缘，该物种在属内处于 somewhat isolated position。此外，背甲还被带有长感觉毛的正常小孔的突出小瘤密集覆盖。为了便于将该新物种与其最接近的同属物种进行鉴别，提供了一份关于1870年布雷迪所描述的来自南部非洲的 属物种的检索表。1977年麦肯齐所描述的 属主要分布在非洲热带地区，仅有少数物种出现在其他地区。 采自博茨瓦纳奥卡万戈三角洲郊区的洪泛平原。它体长约0.4毫米，主要可通过较小且更呈椭圆形的瓣膜与同属其他物种区分开来。我们得出结论，南部非洲的Cypridopsinae介形虫迫切需要通过形态特征和DNA序列数据进行综合分类修订。
