The new large tree species Luetzelburgia amazonica D. B. O. S. Cardoso, L. P. Queiroz & H. C. Lima is described, illustrated and discussed based on collections from the state of Rondônia in Brazil. It is the only species of the genus occurring in the Amazon basin. Luetzelburgia amazonica resembles L. trialata (Ducke) Ducke based on the number and morphology of leaflets, fruit size and the dark brown sericeous indumentum on the inflorescence, but differs mainly in its larger flowers, pinkish petals and very distinct standard petal shape.

A nova espécie de árvore Luetzelburgia amazonica D. B. O. S. Cardoso, L. P. Queiroz & H. C. Lima é descrita, ilustrada e discutida baseada em coleções do estado de Rondônia, Brasil, sendo, portanto, a única espécie do gênero que ocorre na Bacia Amazônica. Luetzelburgia amazonica se parece com L. trialata (Ducke) Ducke pela morfologia e número de folíolos, tamanho dos frutos e o indumento seríceo marrom escuro da inflorescência, mas difere principalmente pelas flores maiores com pétalas róseas e morfologia do estandarte bem distinta.
