摘要：This present research aims to study the relative sexual size dimorphism of Centrobolus (Cook) in 18congenerics. Millipedes illustrated reversed sexual size dimorphism (SSD) where females were larger thanmales; and broke Rensch’s rule as this dimorphism increased with body size. SSD was calculated in 18 speciesof the genus Centrobolus and illustrated was regressions; male versus female SSD and SSD vs body size. Anallometric equation for Centrobolus was (1) ŷ=0.00051x-0.01071. SSD ranged from 0.63–2.89 (1.55±0.63;n≥18) and was not negatively correlated (R=0.70485; P=0.00109; n=18 spp.) with volume ranging from 284–2683 mm3 (1097.89±638.06; 18). The rejection of the rule appears consistent among arthropods.
