Nomenclature, 1999].

Udeina stuckenbergi Zicsi, 1998: 69 [presently corrected].

Material examined: Holotype MNSA /Olig.00536 and two juvenile paratypes NMSA / Olig.02690, Eastern Cape: 16 km from Stutterheim (32º32'S: 17º29'E) off Road 358, Mr Warren’s farm, at approx. 1000 m, on bank of small stream approx. 10 cm depth in moist soil, 19 January 1990, JDP & B. R. Stuckenberg.

Remarks: The external and internal characters accord with Zicsi’s description. This species differs notably from congeners in having spermathecae in segment 9, their pores located in intersegmental furrow 8/9, and only one pair of seminal vesicles. Also the shape of spermathecal ampulla and diverticulum are specific ( Figs 24–25 ). The relationships between U. stuckenbergi and U. montanus are uncertain.

An error in the species name occurred in the original description ( Zicsi 1998). The name ‘ stuckenbergeri ’ should have been ‘ stuckenbergi ’. Zicsi (1998: 69) clearly dedicated the species to Dr B. R. Stuckenberg, Director emeritus of the Natal Museum, when he wrote: ‘ Die neue Art wird zu Ehren des Sammlers Prof. Dr. B. R. Stuckenberg, dem damaligen Direktor des Natalmuseums, benannt ’. In accord with the International Code of Zoological Nomenclature, 1999, Art. 32.4 and Art. 32.5, the mistake is corrected here.
