Only a single species of the genus Trachusa Panzer, 1804 is currenlty known from southern Africa: Trachusa aquiphila (Strand, 1912). A second species is described here from Namibia: Trachusa namibiensis sp. n., with habitus similar to T. aquiphila, but distinguished by morphological characters and colour features. The new species combines features of the subgenera Trachusa (Paraanthidium Friese) and Trachusa (Massanthidium Pasteels), therefore the latter is here regarded as a junior synonym of Paraanthidium, and all three species which have been assigned to subgenus Massanthidium are here transferred to Trachusa (Paraanthidium). Trachusa (Paraanthidium) and Trachusa (Congotrachusa) are now the only subgenera occurring in sub-Saharan Africa. Trachusa namibiensis sp. n. seems not to be rare and was found sympatrically with T. aquiphila. It is polylectic and was found on the wing in autumn (March).
目前已知仅有一种1804年命名的特拉胡萨属（Trachusa Panzer）昆虫分布于非洲南部：嗜水特拉胡萨蜂（Trachusa aquiphila (Strand, 1912)）。本文描述了来自纳米比亚的第二个物种：纳米比亚特拉胡萨蜂（Trachusa namibiensis sp. n.），其形态与嗜水特拉胡萨蜂相似，但在形态特征和颜色特征上有所不同。新物种兼具特拉胡萨属（拟花蜂亚属Paraanthidium Friese）和特拉胡萨属（大花蜂亚属Massanthidium Pasteels）的特征，因此后者在此被视为拟花蜂亚属的次异名，所有已归入大花蜂亚属的三个物种在此被转移至特拉胡萨属（拟花蜂亚属）。特拉胡萨属（拟花蜂亚属）和特拉胡萨属（刚果特拉胡萨亚属Congotrachusa）是目前撒哈拉以南非洲仅有的亚属。纳米比亚特拉胡萨蜂似乎并不罕见，与嗜水特拉胡萨蜂同域分布。它是多花采集的，在秋季（3月）可在空中发现。
