Nisquallia olympica Identification

The identification characteristics I present here come from the 1952 paper by James A. G. Rehn containing the original description of the new genus and species Nisquallia olympica. I do not intend these pages to be a definitive identification, just a presentation of some characteristics I was able to photograph.

This page compares figures from the Rehn paper to the nearest photos I could make of my specimens.

1. Rehn Fig. 1—“Lateral outline of fastigio-facial angle” male

2. Male head from a slightly different angle to show the countours of the fastigium and face

3. Rehn Fig. 2 “Dorsal view of fastigium”

4. Rehn Fig. 7.—“Nisquallia olympica new genus and species. Male (allotype). Mount Ellinor, Mason County, Washington. Cephalic view of head. (Greatly enlarged.)”

5. Rehn Fig. 10.—“Nisquallia olympica new genus and species. Female (type). Mount Ellinor, Mason County, Washington. Cephalic aspect of head. (Greatly enlarged.)”

6. Female from three-quarter, showing similar features to the male in image 2..
