註釋

"Eryma foersteri, new species, is described from the Stockade Beaver Member of the Sundance Formation, Wyoming. This represents the first erymid to be described from Jurassic rocks in North America and the fourth member of the family to have been described from the continent. The discovery suggests that, early in their known geologic history, the Erymidae expanded into a rather broad geographic range"--P. [1].
