mirabilis Westwood, 1833: MEX
phragmitis (Gordh & Trjapitzin, 1981): USA (FL)
Remarks
Sp. 1 is very close to C. phragmites, but the latter has minute punctures on the frontovertex anterior to the anterior ocellus scattered, a tan area extending from the interantennal area to the gena, and the foreleg all yellow, while sp. 1 has the minute punctures anterior to the anterior ocellus roughly in 2 parallel lines, the tan area in the interantennal area absent or at least not extending to the gena, and a dark ring at the base of the fore tibia. Sp. 2 is like C. phragmitis, but the scutellum is yellow medially, instead of all dark. Like C. phragmites, both macropterous and brachypterous forms exist.
