Rhopalothrix andersoni

This species occurs in cloud forest, from 1300–1440m elevation. It is known from two montane sites: Sierra de Agalta in eastern Honduras, where it is sympatric with Rhopalothrix therion, and Cusuco National Park in northwestern Honduras. The three known specimens are from Winkler samples of sifted leaf litter. (Longino and Boudinot 2013)
