Pembatoxon insulare van Goethem 1975: 207-216.

Notes.

This species was found only in FRs (Table 2) in leaf litter and rotting wood. The only spermatophore obtained was partially digested but the slug recalls Pembatoxon insulare in all other respects including the radula. Van Goethem (1975) noted the holotype (BMNH) was collected in 1901 from "Pemba Island, E. Africa" by C. Crossland but gave no further locality.

Two additional urocyclid slugs were recorded from Pemba by Voeltzkow (1923, p.173) who noted their appearance after heavy rain. These were the only previously recorded speices not relocated in our survey. The difficulties in inventorying slug faunas are well-known ( Cameron and Pokryszko 2005) so this does not necessarily imply their absence. They are Elisolimax roebucki (Simroth, 1910) (as Urocyclus roebucki ) and Trichotoxon heynemanni Simroth, 1888 (as Trichotoxon voeltzkowi Simroth, 1910).
