Land snail biogeography and endemism in south-eastern Africa: Implications for the Maputaland-Pondoland-Albany biodiversity hotspot

taxa of COEs are presented in the Table 3. Twenty-nine species are restricted to COEs, with 21 (72%) of them being narrow endemics. Those species restricted to COEs are dominated by urocyclids (72%) showing an adaptive radiation in narrow ranges (76% of them being narrow endemics) representing almost all centres. They are followed by rhytidids (28%) with one spe- cies of Natalina each from Natal and extended Pondoland centres, one species each of Afrorhy- tida, and Nata from the Albany-Knysna centre, one species of Capitina from the Knysna CONE and one species of Chlamydephorus each from the Albany-Knysna centre and the Mid- dleveld CONE. A spatial comparison of COEs with biomes [25] and the protected area net- work of SA is presented in Fig 4D and 4E. Spatial patterns of land snail species richness for SEA and measures of endemism within the SEA dominion are mapped in Fig 7. Fig 3.
