The genus of red millipedes Centro bolus is distributed in southern Africa between -17 to -35° S. Species richness is negatively related to latitude. In this paper, I check for a correlation between species richness and longitude. Species richness was not significantly related to longitude (r=0.14, Z score=0.21, n=22, p=0.42) although over half the species (12) occurred between 30-34°E. The absence of a longitudinal gradient in species richness serves as a control for the latitudinal gradient already known in species richness.
