Another Z. americanum here?
According to Gordh (1998), the most reliable character for separating Z. americanum is:

"...a transverse, dark stripe along the exposed margin of the mesoscutum (which also projects beneath the posterior margin of the pronotum). Laterally this stripe becomes two enlarged spots. This character is present only in Z. americanum."

The "two enlarged spots" mentioned by Gordh are clearly visible along the suture between the pronotum and mesoscutum in your image above.

The original 1916 description of Girault (as Z. americana) can be read at this BHL link. Girault begins by stating:

"There are no metallic lines on the face;..."

That's consistent with your image above, and with your recent post of Z. americanum from Texas. He goes on to mention two occipital stripes...which appear to be absent here, but present in the Texas specimen. Perhaps that's attributable to variation in the species?
