Estimated relatedness indices of each group collected from the same host web.

Red dashed lines are upper and lower boundaries of 95% confidence intervals of the relatedness under the null hypothesis of random permutation. Blue dashes are the mean relatedness of each group collected from the same host web. Bars around blue dashes are the 95% confidence intervals of the estimated relatedness. * indicates that the mean relatedness of group members is significantly higher than random permutation. # indicates the mean relatedness of group members is significantly lower than random permutation. (A-D) the group-living A. miniaceus, in which (A) all individuals, (B) males, (C) females, and (D) juveniles; (E-G) the group-living A. cf. fissifrons, in which (E) all individuals, (F) adults, (G) juveniles; (H) all individuals of the solitary A. fasciatus; (I) All individuals of the solitary N. trigonum. The relatedness analyses only applied the groups where sample size larger than 2.
