Identification
Similar by most accounts to C. valvata.
Described as a "dark species" with the basal area of the forewings slightly ochreous and opaque; anal membranes of all 4 wings orangish with the posterior margins being grey; 1st and 2nd transverse crossveins lightly infuscated (just as seen in valvata).
TL - "Sonora, Mex" (Female) & "Camp Grant, AZ, USA" (Male)
dissimilis (Mex): Described as a "dark species" with the basal area of the forewings slightly ochreous and opaque; anal membranes of all 4 wings orangish with the posterior margins being grey; 1st and 2nd transverse crossveins lightly infuscated (just as seen in valvata).
vs.
valvata (sw. USA & n. Mex.): C. valvata is described as having a "straw-colored" venter + "dark wing bases". First cell at base of wing dark anteriorly then blending to an ochreous-tan. Basal wing veins may be tan or straw-colored (not variegated with orange). Pronotum dark.
vs.
furcata ("lower Calif." = Baja, Mex): It is important to mention that C. furcata is described as having an "oranginsh" venter and operculae + "variegated orange and black at bases of wings". First cell at base of wing ochreous-tan and ~clear. Pronotum dark with a light tan or brownish spot on front margin of each side.
Range
TL - "Sonora, Mex" (Female) & "Camp Grant, AZ, USA" (Male)
Extent of RANGE is not clearly defined: sw. USA may include NM-AZ extending s. into adj. Mexico (????)
Remarks
The Type Locality & original description of material from Arizona likely belongs to the recently described taxon, Cacama moorei and not C. dissimilis
NOTE: TL - "Sonora, Mex" (Female) & "Camp Grant, AZ, USA" (Male)
