Abstract- In this paper, I test for a relationship between surface area and species richness in red millipedes Centrobolus Cook, 1897. Surface area was negatively related to species richness (r=- 0.62, Z score=-4.19, n=37, p<0.01) (y=-0.00711055x + 26.2); across species (r=-0.55, Z score=-2.70, n=22, p<0.01) (y=- 0.00886731x + 29.3) and females (r=-0.55, Z score=-2.70, n=22, p<0.01) (y=-0.00484857x + 22.8). The mean species surface area at high species richness was 1804 mm2 (S.D.=203 mm2). The mean female surface area at high species richness was 1961 mm2 (S.D.=371 mm2). Female surface area at high species richness was very different from species surface area at high species richness (t=4.09, n=19, p<0.01). Female surface area at low species richness was not significantly different from species surface area at low species richness (t=-2.57, n=3, p=0.12). The mean female surface area at low species richness was 2741.6811207 mm2 (S.D.=619.56066078139 mm2) was significantly different from the female surface area at high species richness (t=-3.116, n=19, 3, p=0.0054). The mean species surface area at low species richness was 2509.916172 mm2 (S.D.=338.96352202721) was not significantly different from the specific surface area at high species richness (t=-3.5111, n=3, 3, p=0.06162).
