The species Krauseia clemensi was named by Sloan R.E. in 1981, and is also known as Parectypodus clemensi. Fossil remains of members of this species have been found in the Torrejonian (Paleocene)-age strata of the San Juan Basin of New Mexico and Wyoming. An approximate weight comparison for P. clemensi is the weight of one standard mouse, around 25 g.
