A new moss species, Distichophyllum shevockii B.C. Tan, Ochyra, B.C. Ho & Bedn.Ochyra (Daltoniaceae), is described and illustrated from the material collected on the island of Mindanao in the Philippines. The species is closely related to D. noguchianum — a species endemic to the Philippine island of Mindoro — from which it is easily distinguished by its leaves that are abruptly piliferous, with a very long, smooth, straight or flexuose, capillaceous acumen, usually as long as up to half of the leaf lamina. These two species, along with D. iwatsukii from Borneo, belong to Distichophyllum sect. Platyovatophyllum which has isomorphic and non-complanate leaves, giving the plants a hirsute overall appearance unlike most other congeners.
