Synonyms and other taxonomic changes
Tetrix brunnerii (BolĂ­var, 1887)
Very like T. ornata, but more northern and at higher elevations. The two are likely one species, and some individuals in the zone of contact are impossible to place in one species or the other. This species differs in having the fastigium (forehead) strongly produced forward when viewed in profile, and with a concavity below, just above the antennae. T. ornata has the fastigium less produced, and less "notched" in profile above the antennae. T. brunnerii has more slender hind legs, but tends to be a stockier insect otherwise, more often occuring in the form with a short pronotum.
Oregon to Michigan and New York and northward. South in Rockies to at least Utah and Colorado.
