        | Diagnosis |  | 
        | Comment | Absent from SW- and NE-West Australia, humid regions of southeastern and east coastal Australia and from the tropical north. | 
        | Etymology | Presumably named after the Latin levis (smooth), referring to the relatively smooth scalation (compared to the previously described Nephrurus asper).  (G. Shea, pers. comm., 9 Feb 2024) 
 N. l. occidentalis was named after Latin occidentalis = "western" and refers to its western distribution.
