The lichen family Ophioparmaceae contains three genera: Boreoplaca, Hypocenomyce and Ophioparma. The genus Hypocenomyce is reported here for the first time for China, being represented by the species Hypocenomyce scalaris which is distributed in south-western China. For the genus Ophioparma, one new species is described in this paper, namely Ophioparma pruinosa Li S. Wang & Y. Y. Zhang sp. nov., which is characterized by a pruinose thallus and the presence of usnic acid. Ophioparma araucariae is also reported as new for the Chinese lichen biota. Previous reports of O. lapponica in China are recognized as misidentifications of O. ventosa. Descriptions, keys and phylograms are provided for these species.
