Can you identify this?

Fall described this species in 1912 from specimens collected in June and July in New Mexico. Green also recorded this species from Arizona, California, Texas, Utah, and Chihuahua. His Colorado records include Royal Gorge, Junction Creek, San Luis Valley, and Stollsheimer.

The pink females are said to closely resemble the more common CA species, M. angustus LeConte and have 6-segmented antennae, 4-segmented tarsi. The CO specimens all have 3-segmented “
