Pickfordia magnisetosa OMODEO, 1958

Pickfordia magnisetosa OMODEO, 1958: 30 , OMODEO 2000: 194, CSUZDI et al. 2009: 67. Pickfordia (Pickfordia) magnisetosa : CSUZDI 1993: 67, CSUZDI 1995: 117, CSUZDI 1996: 363,

CSUZDI et al. 2009: 67.

Diagnosis. L. 75–90 mm, D. 1.5– 2 mm. No. segments 163 – 190. Colour pale. Head prolobous, first dorsal pore 5/6. Spermathecal pores in 7/8, 8/9 ab. Clitellum saddle-shaped on ½13–19. f 14, paired in between a–a. f 18. Genital field oblong, prostatic pores 17, 18, 19.

Septa 5/6–11/12 somewhat thickened. Muscular gizzards lacking. Calciferous glands 14–15 open separately in the oesophagus. Last pair of hearts 12. Typhlosole vestigial. Excretory system holoic.

Testes 10, 11 free. Vesicles 11, 12. Prostates 17, 18, 19. Penial setae uniform, only at the prostates in 17 and 19. L. 0.65–0.70 mm, D. 0.01 mm, tip pointed, ornamentation small serrated bars. Spermathecae with bean-shaped ampoule and a long duct. A small heart-shaped diverticulum attached entally to the duct.

Remarks. According to SOMON (1995) P. magnisetosa has no spermathecal diverticulum, but a looping of the duct was misinterpreted by OMODEO (1958) as free spermathecal diverticulum. Our specimen agrees completely with the original description therefore we concluded that it was SOMON (1995) who misinterpreted this structure ( CSUZDI et al. 2009).

Distribution – Guinea, Mt. Nimba.
