Grammoptera Audinet-Serville, 1835

Grammoptera  Audinet-Serville, 1835 is represented by three species in the Pacific Northwest. These are molybdica (LeConte, 1851 ["1850"]), rhodopus (LeConte, 1874), and subargentata (Kirby in Richardson, 1837).  

Notes

The description of Grammoptera militaris (Chevrolat, 1855) indicates that the original specimen was taken in the Rocky Mountains, but the species is only known from California and Mexico. A similar discrepancy also existed for the species Desmocerus aureipennis, which Chevrolat described along with ​militaris and which was only known to Linsley and Chemsak (1972) from the Sierra Nevadas and Siskiyou Mountains of Southern Oregon.  Halstead (1990) reported the surprising discovery of a small number of aureipennis museum specimens that were taken from Northern Washington, very near the British Columbian rockies (see full discussion on Desmocerus aureipennis species page). It is still possible, then, that a few isolated populations of militaris exist in the northern Rockies that have remained unknown since the species' discovery.
