Kazimierzus phumlani Nxele & Plisko

sp. n.

Kazimierzus phumlani Nxele & Plisko , sp. n.

( Figure 3 View FIGURE 3 )

Locality and material. South Africa: Western Cape: Doringbos , 25 km N of Doringbos on R364 (31.77182S 19.29114E), 734 m, 05.ix.2011, J.D. Plisko, S. James, T. Nxele, P. Madonda leg. GoogleMaps

Holotype. One clitellate, NMSA / OLIG. 04951/2e.

Additional material. Six juveniles, NMSA / OLIG. 04951/2b, c.

Description. External. Holotype: Body length> 60 mm, abscised, width 6 mm at tubercula. Segment number>105. Colour whitish grey. Prostomium prolobous, small. Preclitellar segments with secondary annulations: segments 1–2 simple and fused, appearing as one segment, 3 simple, segments 4–7 with two annuli, 8–9 with second annuli appearing smaller. Setae aa <bc: ab>cd, closely paired, minute. Male pores not observed. Female pores not observed. Spermathecal pores not observed. Clitellum saddle-shaped on 12–22, segmented, dorsal borders well-marked. Tubercula pubertatis on 17–20, band in clitellar tissue. Genital papillae on 13–27.

Internal. Septa 4/5, 5/6 thickened, strong, 6/7, 7/8, 8/9, 9/10 thickened but less so. Other septa thin. Gizzard very small in 7. Calciferous glands in 10, separated dorsally and ventrally. Intestinal origin in 13. Dorsal blood vessel simple throughout the body. Nephridia holoic, one pair per segment with J-shaped bladders. Holandric, male funnels in separate sacs, both pairs iridescent in clitellate holotype. Seminal vesicles in 11 and 12, one pair per segment, pair in 12 larger. Spermathecae between ab and cd setal lines, multiple per segment in 13/14–15/16, 1 or 2 at each side, round-shaped. Genital glands large ( Fig. 3 View FIGURE 3 ) on 13–27.

Etymology. Named after Phumlani Madonda (KwaZulu-Natal Museum- technical assistant) who helped in the collection of this species.

Remarks. This species is similar to K. occidualis ( Plisko, 1998) , Both species have clitellum on 12–22, spermathecae in segments 13/14–15/16. However, K. occidualis has calciferous glands in 10–11 with septum 10/ 11 in the middle of glands whilst K. phumlani has calciferous glands confined to segment 10. In K. occidualis the anterior pair of seminal vesicles is confined to segment 11, the posterior pair may extend through 12 and 13, while in K. phumlani the anterior pair is confined to segment 11 and the posterior pair to 12. The complex of characters specific for this species is shown in Table 1.
