Size matters in myriapod copulation

Abstract

Size correlates with mating in Centrobolus. I tested for the presence of relationships between male length and copulation duration in C. inscriptus by performing double mating. Males differed from females in mass, length, and dorsal tergite width. Male length was positively related to the duration of the first mating but negatively related to the duration of the second mating which related to sexual size dimorphism (SSD).
