Abstract: The re-discovery of Catasetum mojuense A.T. Oliveira & J.B.F. Silva (Orchidaceae), an Amazonian species described in 1999 from the State of Pará, Brazil, is reported. In addition to geographic distribution data, a morphological description, taxonomical and ecological comments, conservation status assessment and photographs of C. mojuense are also provided. The species is characterised by having epiphytic habit, non-resupinate staminate flowers, brown-spotted petals, galeiform and smooth (no ribs) lip, lateral lobes with sparsely short-fimbriate margins and convergent antennae. Catasetum mojuense is morphologically similar to Catasetum discolor (Lindl.) Lindl, but is easily distinguished by the longer sepals and petals and the spotted petals on the staminate flowers. The new locality of occurence for C. mojuense is approximately 190 km east of the type locality, also in the State of Pará. The species is assessed as Critically Endangered. Habitat depletion and the limited number of sites of occurrence are the main concern for the conservation of C. mojuense.
