Mapping the available data on reproductive biology of the Gonyleptidae on the phylogeny of the family, it is possible to infer that paternal care has evolved at least three times independently: once in the clade ProgonylePToidellinae + Caelopyginae,once in the GONYleptinee, and once inThe Heteropachylinaes, which occupies a basal position within the group.

Evolution of exclusive paternal care in arthopods.

Comparisons suggest parallels between prezygotic nuptial gifts and exclusive postzyGotic male care and support the hypothesis that, in arthropods, male behaviors that enhance female reproductive success either directly, by releasing females from the fecundity constraints of maternal care, or indirectly, by identifying mates with superior genes (handicap principle), are traits on which sexual selection has acted.
