The null hypothesis that there was no difference and relationship between predicted species richness and time was tested in red millipedes Centrobolus. The alternative was that species richness differs over time was considered. The least-squares regression equation for SSD versus species richness was calculated from given data (y = -11.8 · x + 14.5). SSD at four points in time was substituted into the equation to get species richness at four points for male C. ruber and female C. digrammus. The difference in species richness from the C. ruber substitution was 0.01 and 1.46 from the C. digrammus substitution. When the multiplication of the smaller value against the index (1.88) resulted in 0.01 for the C. ruber substitution while the C. digrammus substitution was controlled (1.46). This supports the idea that two species may have gone extinct over equal times when female size increased.
