Key to the known species of Nothrholaspis Berlese, 1918 (based on adult female)

Information about other species of Nothrholaspis came from published descriptions and illustrations, not from the examination of specimens. Nothrholaspis planus Vitzthum, 1935 is excluded because the setae on the body and legs are almost all smooth, and it is therefore better placed in Macrocheles (Vitzthum, 1935).
