Etymology

Paranephrolenellus is named for the close similarity of this genus to Nephrolenellus. The names of the species are derived as follows.

• P. besti is named in honor of R.V. Best, for his work on the olenelloids of the Laurentian Cordillera.
• P. inflatus refers to the inflation of the lateral cephalic border and base of the genal spines.
• P. klondikensis is named for Klondike Gap, Chief Range, where the species was first discovered.[1]
