Symmetry in ejaculate volumes of Centrobolus inscriptus Attems (Spiroboloidea: Trigoniulidae)

Mark Ian Cooper

I test for symmetry in ejaculate volumes measured as disintegrations per minute (dpm) deposited by males in ejaculate storage organs of Centrobolus inscriptus in single, double and artificially-terminated matings. Combined data showed symmetry in dpm values (left-right: X ± SE = 48.11 ± 126.1828; n = 21). No significant differences between the left and right ejaculate volumes occured (T = 711.5, n = 59, P = 0.19). Symmetry in ejaculate volumes was consistent with the mechanism of sperm displacement i. e. mixing-self-sperm displacement by phallopods.
