Udeina pliskoae Zicsi, 1998: 68 .

Material examined: Holotype NMSA /Olig.00729, and one immature paratype NMSA/00729 a, both collected in KwaZulu­Natal: Eastwolds (30º00'S: 29º55'E) area, approx. 30 km north­west of Ixopo, along road to Bulwer , 29 January 1991, JDP & B. R. Stuckenberg; clitellate, holotype dissected.

Remarks: External and internal characters accord with the original description.Additional data are as follows: prostatic pores in segment 17 on small rounded papillae; male pores in front of b setae evident in 18. Vasa deferentia extend to segment 18, entering body wall separately from prostatic duct. Spermathecae in segment 8, spermathecal ducts entering into intersegmental furrow 7/8. Spermathecal duct short; spermathecal diverticulum chambered, unilobate ( Fig. 16), iridescent, containing sperm. No sperm were observed in duct or in ampulla. Prostate ( Fig. 17) elongated in segments 16–19. U. pliskoae is similar to U. mapelane , differing in two substantial characters. In U. pliskoae spermiductal funnels are enclosed, but they are free in U. mapelane ; the size and shape of the whole spermathecae, and notably the length of spermathecal duct in U. mapelane which is much longer than this in U. pliskoae . The similarity between U. pliskoae and U. reichei indicated by Zicsi (1998) cannot be confirmed. These species differ also notably in the shape of spermathecae and prostate ( Figs 16–17, 21–23).
