Rhopalothrix stannardi

Recent collections of this species are from lowland wet to moist forest habitat, from 70–270m elevation. The type is apparently from a somewhat higher site near Ocosingo. All recent specimens are from Winkler samples of sifted leaf litter. In quantitative sampling carried out during Project LLAMA, this species occurred in 4 of 100 miniWinkler samples at a lowland Chiapas site and in 7 of 100 samples from in and near Tikal National Park in Guatemala.
