Type data. Centris griseola was described based on four females collected by the American botanist, entomologist and pioneer chemist Robert Rickert Dreisbach (1888–1964) in Iguala , Guerrero State , Mexico . In 1907, Dreisbach began his plant collection, but by 1932 his interests had begun to swing to insects, and plant collecting became a secondary but important hobby. Collecting trips took him to many parts of the United States , Mexico , and Central America in search of insects and plant specimens. His insect collection grew to be one of the largest private collections in the nation ( FLETCHER, 1964 ) . The holotype of C . griseola is deposited at SEMK .
