A new species of Ophiocordyceps, Ophiocordyceps lanpingensis collected from Lanping County, Yunnan Province, southwestern China, was described based on morphological characteristic, ITS1-5.8S-ITS2 rDNA sequences analyses, 5-gene (nrSSU, nrLSU, tef-1α, rpb1 and rpb2) sequences analyses and MAT1-2-1 gene sequences analyses. This species was characterized by thinner stroma, smaller perithecium, thinner ascospore (multiseptate with short septation). The phylogenetic analyses based on the ITS, the 5-gene and MAT1-2-1 gene dataset showed O. lanpingensis had the closest evolution relationship with O. robertsii and O. sinensis, but still had obvious distances to them. Both morphological character and systematic analyses supported that O. lanpingensis was a new species of Ophiocordyceps.
