Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. Lochman 1952 | The species is most closely related to the other two Cordilleran Wanneria species, W. rowe i(Walcott) and W. occidens Walcott, but in so far as comparison can be made it differs from them in (i) the sudden bulge of the anterior lobe just infront of the palpebral lobes, (2) the very short occipital spine, and (3) the somewhat shorter eyes. The author recognizes this form as a species differing from described ones as noted above; and this particular form as a variety of that species in which the intergenal and genal spines are placed as noted. |
