Tuscumbia (coll. at lights, alt. Hwy 72, ~2 mi. w. of Tuscumbia), Colbert Co., AL

Coll. M. Reynolds (+B.& G. Reynolds)
This taxon is not well known nor is the extent of its range geographically.
This "ssp." diverges from nominate T. davisi in wing shape and the degree of infuscation along the apical margins/cells of the forewings (smoky grey coloration in 6 to 7 wing cells apically - not restricted to wing veins as seen in nominate davisi)
NOTE: The contrast in this image has be adjusted and the wings appear washed out
(esp. the "smoky infuscations" in the apical cells)
They seem to replace typical T. davisi in e. Arkansas, wc. Miss, nw. Mississippi, sw. Tennessee possibly extending east into nw. Alabama (where cicadas with very similar features to those described as harnedi also occur).
T. davisi harnedi is also similar to T. auriferus and easily confused with that species. Since the calls of both T. auriferus and T. davisi are similar, there is still some thought as to the proper placement of ssp. harnedi in relationship to the aforementioned.
Cicadas more typical of nominate Tibicen davisi can be found further east and southeast of this region.
