ABSTRACT. Scapania pseudocontorta sp. n., S. spiniloba sp. n., and S. zhukovae sp. n. were present in collections by Dr. David G. Long from East Nepal, Sankhuwasabha District: Pemathang Kharka, S side of Barun Khola. Their descriptions and known ecology are provided. Diagnostic characters of each species are defined and illustrated. S. pseudocontorta shares characters with S. contorta and S. hians but differs in its smooth leaf cuticle; S. spiniloba occupies an intermediate position between S. hians and S. orientalis; and S. zhukovae is related to S. ornithopoides differing from it primarily in distant rather broad-based marginal teeth and unistratose cortex of extremely thick-walled cells.
