  abstract = {{C}olony breeding systems and dispersal strategies of eusocial insects shape the genetic structure at the colony, but also at the population level. {M}ost of the few molecular studies dedicated to termites suggest that winged reproductives disperse far enough to secure the formation of outbred founding pairs. {H}owever, these studies almost exclusively focused on wood-feeding termites and knowledge about the dispersal potential of winged reproductives is missing for soil-feeding termites. {W}e investigated the dispersal and mating strategies of {E}mbiratermes neotenicus and {S}ilvestritermes minutus ({T}ermitidae, {S}yntermitinae), two very abundant soil-feeding species from the {N}eotropics. {I}n both species, analysis of microsatellite markers indicated low genetic similarity between closely located colonies and low genetic differentiation between populations separated by less than 10 km. {E}ach of the 39 {E}. neotenicus colonies originated from a single pair of primary reproductives and the mean inbreeding coefficient of sterile castes was only slightly different from that expected in offspring of an outbred pair. {M}ost {S}. minutus colonies (34/41) were consistent with outbred biparental foundation. {I}n three mature colonies, the genotypes of sterile castes suggested their origin by mixing of multiple related reproductives. {F}inally, four colonies in late stage of the colony life cycle contained sterile populations originating from multiple unrelated reproductives. {W}e conclude that long-distance flights resulting in outbred reproduction are common in these soil-feeding species in pristine habitats but that other factors, such as mating preferences, could increase relatedness between founders.},
