Abstract
A new species, Uncifera motuoensis (Orchidaceae: Epidedroideae: Aeridinae) from Xizang Autonomous Region, China is described and illustrated with detailed photos and scientific illustration. Detailed morphological comparisons indicate that U. motouensis is similar to U. obtusifolia, but differs in having entire mid-lobe of lip, narrower leaf blade and wider pollinarium stipe. For the identification, a key to the known seven species of Uncifera is presented.

Diagnosis: Uncifera motuoensis is similar to U. obtusifolia Lindl. (1958), but differs in having an entire mid-lobe of lip (vs. trilobe), narrower leaves (linearoblong vs. obliquely oblong) and wider pollinarium stipe wings (leglike vs. cuplike at closing) (Table 1).
Etymology: The species epithet is named after the type locality, Motuo County.
