Does sexual size dimorphism vary with female size in forest millipedes Centrobolus Cook, 1897?


Author(s): Mark Cooper

Abstract: This study aimed to determine whether the variation responsible for breaking Rensch's Rule when Sexual Size Dimorphism (SSD) increased with body size was due to male-biased or female-biased variation by studying a sex-based set of morphological characters. Variation in female volume based on length and width measurements was associated with the SSD in the forest millipede genus Centrobolus. There was a significant positive correlation between SSD and female size (r=0.56, Z score=2.76, n=22, p<0.01). The correlation coefficient between SSD and female size did not differ significantly from the correlation coefficient between SSD and species size (z-statistic=-0.7078, p=0.4790). The morphological differences among the polygynandrous reproductive systems occurring in Centrobolus with higher SSD and larger females were discussed.
