Upper process of epiproct divided in lateral view. 7. Declivity between processes of epiproct vertical. 8. Lower process of epiproct longer than upper process. 9. Lower process of epiproct much longer than upper process. 10. Knobs present on tergites 5 and 6. 11. Both processes of epiproct of about the same length. 12. Lower process of epiproct widely forked in dorsal view. 13. Declivity between processes of epiproct medially carinate. 14. Declivity between upper and lower processes of epiproct with an extra medial process. 15. Knobs on tergite 8 angulate. 16. Notch between knobs of tergite 8 broad in dorsal view. 17. Notch between upper and lower processes deeply incised in lateral view. 18. Lower process of epiproct narrow in dorsal view. 19. Upper and lower processes of epiproct forming a 90 degree angle in lateral view. 20. Lower process of epiproct with lower surface bent at mid length in lateral view. 21. Lower process of epiproct constricted near apex in dorsal view. 22. Lower process of epiproct evenly tapered, not inflated at midlength in dorsal view.

points to a need for careful conservation of the tributaries of the Sacramento River. The Californica Group remains an important and virtually untapped resource to learn more about the paleogeography of this part of western North America. The use of sequence data on a phylogeographic scale remains a next best step in sorting out the range relationships of these populations and species in understanding this perplexingly complex group of stoneflies.
