The specific epithet \u003ci\u003edenegrii\u003c\/i\u003e honors Ramón P. De Negri, a former Mexican Minister of Agriculture who facilitated the exploration and collection of the type material. Historical Context: Discovered in 1923 by a local resident and scientifically described by Alwin Berger in 1929.
