Lygaeid possibly Melacoryphus admirabilis on Brickellis - Melacoryphus

Lygaeid possibly Melacoryphus admirabilis on Brickellis - Melacoryphus
6 miles NW Lyons, Boulder County, Colorado, USA
August 18, 2006
Size: BL ~7-7.5 mm
This lygaeid is on Brickellia in the CO foothills at ~ 6400' elevation. Using Slater, 1992, I tried to key it out, though keys are very difficult for amateurs. First, to genus Melacoryphus: length more than 6 mm, hemelytral membrane of macropter usually black, sometimes with white corial margin of white with contrasting dark veining
Then to the key to Melacoryphus species: Basal margin of hemelytral membrane white, hemelytral membrane brown to black with only margins white, and dark markings of clavus and corium black; frequently with apical third of corium and half of clavus nearest scutellum red, which keys out to Melacoryphus admirabilis. And so, this species is my best guess.
This individual is extremely similar to #1275432, which was taken the previous year in the same exact locale on the same Brickellia plants. On this individual,the lygaeid venation is very evident. Any help with this attractive bug is most appreciated.
