ABSTRACT

A correlation coefficient matrix including 16 factors was constructed to summarize the polygynandrous mating systems of red millipedes Centrobolus. The sixteen factors summarized were abundance, copulation duration, ejaculate volume, latitude, longitude, mass, mating frequency, moments of inertia, sex ratio, spine length, spine number, sternite prominence, size of males, size of females, sexual size dimorphism, and tarsal pad length. Correlation coefficients were included for interspecific values between 111 pair-wise comparisons of 16 factors. The results of this study demonstrated between 46.8-49.5% (52-55) were significant or highly significant relationships between all pair-wise comparisons which were present.
