Izvekova E.I. Diagonosis. Specimens from all studied South Africa samples were identical to previously described specimens from Eurasia in the additional material. As figured in general shape (Fig. 5 A), morphology of the valves (Fig. 5 B–C), head shield, head pores (Fig. 5 D–E), labrum (Fig. 5 F–G), postabdomen (Fig. 5 H), antenna (Fig. 5 I), antennula (Fig. 5 J) and thoracal appendages (Fig. 6 A–F), for comparison, see Alonso (1996) and Sinev (1997). On the other hand, all studied specimens were easily separated from A. martensi sp. n. by several characters, summarized in Table 1. No specimens with intermediate state of these characters were present in the studied material, and these species were not found sympatrically. Character Alona martensi sp. n.
