The copulation duration allometry in Centrobolus (Diplopoda: Spirobolida: Pachybolidae)

Of the determining factors of copulation duration across arthropods, I reviewed variance in forest millipedes. The objective was to calculate duration. null hypothesis mean and were independent body mass. Copulation standard deviation squared for 4 populations millipedes seen literature. correlated with it’s (r=0.95, r2=0.90, n=5, p=0.01). Durations ranged from C. anulatus (34.9 minutes) inscriptus (303 minutes). Female mass z-score=1.86, n=4, p=0.03). Millipedes similar some arachnids where intra-specific size variation.
