Reported from Guatemala (Quirigua, Cayuga and Queriflia), Mexico (Cordoba and Sinaola) and USA, Texas (Southmost, Cameron Co., Brownsville, Hidalgo Co., Santa Ana National Wildlife Refuge) (Blanchard & Knudson 1985; Schoorl (1990).

Remarks. A detailed description was given by Blanchard & Knudson (1985). Later, we indicated the unclear taxonomic position of Z. masoni (Yakovlev et al. 2019b), considering the distinct difference of the male genitalia of other Neotropical Zeuzerinae species currently known.

Diagnosis. The species differs from the other congeners in the male externally and in the genital structure: the forewing has a very dense grey pattern which is significantly darker than in C. ophelia, with a black longitudinal stroke medially, from the base to the apex of the wing; the valve has a wavy saccular margin, significantly narrowed to the apex.

Distribution. USA (Texas), Mexico, Guatemala.
