Size-assortment in Centrobolus Cook, 1897

Positive assortative mating or homogamy was a mating pattern and form of sexual selection in which individuals with similar phenotypes mated with one another more frequently than would be expected under a random mating pattern. I investigated correlations between size measurements in coefficients of variation across sexes, particularly male length versus female width, across ten species of forest millipedes in the genus Centrobolus, and body size. Male length variation was strongly correlated to female width variation (r= 0.9613, r2=0.9241, n=10, p
