The first proandric species of Tritogenia Kinberg, 1867 from Botswana, Tritogenia talana sp.n. (Clitellata, Crassiclitellata, Tritogeniidae).

The earthworm fauna of Botswana is hitherto unknown. A first collecting trip to the regions of Chobe and Tuli Block resulted in the discovery of a new species, Tritogenia talana sp.n. Its reproductive organs show some level of degeneration when compared to other species of Tritogenia. The spermathecae were not observed, testes and sperm funnels are in proandric condition and seminal vesicles are absent. This is the first record of an earthworm species from Botswana.

Four new earthworm species of Kazimierzus Plisko, 2006 (Clitellata, Kazimierzidae).

Four new species of Kazimierzus are described from the Western Cape and Northern Cape, South Africa: K. kleinoodi sp. n., K. nietvoorbiji sp. n., K. nieuwoudtvillensis sp. n., and K. phumlani sp. n. Kazimierzus kleinoodi is distinguished from the other species of this genus by the position of the calciferous glands in 9 and paired spermathecae in five segments. The position of the spermathecae in 11/12-15/16 as well as the position of the calciferous glands in 11 separates K. nietvoorbiji from the other new species. Kazimierzus nieuwoudtvillensis is distinguished from the others by the position of the clitellum (12-25) and spermathecae in four rows. The combination of the position of the clitellum, three rows of spermathecae and the position of the calciferous glands in 10 distinguish K. phumlani from the other species.
