英文摘要	Aristida surperuanensis sp. nov. is described and illustrated. The new species, from southern Moquegua (Peru), differs from A. flaccida in having contracted panicles, spikelets to 1-1.1 cm long and lemmas 5.5-6.5 mm long. The central awn is straight, ascending, 3-6 mm long and lacking a column, the lateral awns are ascending, 1-2.5 mm long and 1/3 as long as the central awns, and the caryopscs are fusiform and 4-4.5 (-6) mm long. A key to the species of Aristida in Peru is included and the conservation status of the new species is evaluated.
