This species is now highly fragmented occurring in 11 populations, only one of which is ostensibly viable – the Morro do Diabo State Park. The key threat for this species is the isolation and small size of the existing populations. A study by Dietz et al. (2000) examined inbreeding depression in small (50 or less) isolated populations of L. rosalia. They concluded that it reduced probability of long-term survival by about one-third. There is every reason to believe that inbreeding depression is likewise prejudicial to the isolated populations of L. chrysopygus.*
