Maccaffertium mexicanum integrum
Location: Burley, Cassia County, ID
Photo Date: 9/14/2019
Remarks: "This could be viewed as terminatum however the posterior bands on each tergite are absent or super pale and restricted to a very small medial area. I can also see the very pale oblique spots at each spirical. this places this as a synonym to intergrum McDunnough 1924. this is the only sample i have seen of this synonym and as a former species it was Stenonema metriotes Burks 1953."
