The taxonomy of the genus is revised. Four species and subspecies are recognized: H. palmeri (Dall, 1905 ), H. lux new species, H. lux lux new subspecies, H. l. chonomphix new subspecies and H. christmani new species. H. palmeri simplex Pilsbry, 1953 is synonymized with H. palmeri. Hendersoniella is most closely related to Holospira on the basis of shell characters and soft anatomical features. The shell is discoidal in shape, not cylindrical, in contrast to other genera of the Holospirinae. This is an adaptation for living in narrow crevices under spalding surfaces of limestone boulders. The species are obligate calcicoles. The genus occurs over a large area of eastern México in the states of Nuevo Leon and San Luis Potosi.
