ResumoIndopottia irieandoana H.Akiyama sp. nov. is reported on the basis of two specimens from Doi Inthanon, northern Thailand, as a second species of a genus recently described from southern India. The lack of a peristome precludes unambiguous familial placement based on morphology, but phylogenetic analyses of sequences from a chloroplast and a mitochondrial locus place the new taxon, with strong support, in the Pottiaceae. Its epiphytic habitat on a tree trunk and a branch near the crown of an emergent tree and a strangler tree, respectively, along with morphological features such as spatulate leaves, a single dorsal stereid in the leaf costa, smooth laminal cells, long rostrate opercula, and eperistomate, upright capsules point to a close relationship to Indopottia zanderi. The morphology is compared with that of related genera. A key to similar genera and species is provided.
