We recovered a significant and positive relationship between relative Tajima's D in the gonad and sexual dichromatism ( r 2 = 0.890, p = 0.003) after correcting for phylogeny, and marginally nonsignificant positive associations with both sperm number ( r 2 = 0.491, p = 0.073) and residual testes weight ( r 2 = 0.298, p = 0.152).
