Note. Currently, there is no example of Crioprosopus iridescens available for diagnosis and to make a determination concerning the status of this species. C. iridescens males can be distinguished by the pale ferruginous elytra, which is highly iridescent, and shining yellowish metallic green under light. The pronotum appears to be the same width as elytra based on the photo (Bezark, 2014, id: 6088). The lateral tubercles of the pronotum are broader and more obtuse than in C. basileus Bates and C. praestans Casey. The mesosternum is nearly planar according to Bates (1885:74). The male antennae of C. iridescens are much longer than in C. championi Bates and C. basileus .

According to the description by White (1853), this species has the following characteristics: Head is ferruginous, grooved in the middle between the antennae, and with an incised line in the middle between the eyes. The notches of the eyes are hollowed out and hairy. The antennae of the male are longer than the body, with the five apical joints sharply edged and compressed. The terminal joint of the antennae is considerably longer than the others, and the edge is notched behind the middle. The 3rd, 4th and 5th joints of the antennae are grooved longitudinally on the upper side. The thorax is ferruginous, and thickly punctured, with a smooth band extending down the middle, which arises from the fore margin, dilated on each side about the middle, and behind the dilation the band is twice as wide as before, and falls behind into a smooth transverse space on the hind edge of the thorax. On each side of the thorax are three depressions, the two hindmost placed nearly transversely and scarred in the center. The scutellum is blackish and acuminate at the tip. The elytra are polished, with many scattered punctures, only visible in some lights; the surface is highly iridescent, shining with a yellowish metallic green. When the light does not shine on the elytra, they appear pale ferruginous. The underside of the body is pale ferruginous, with the lateral edges covered with silky pubescence. Legs with the coxae black, inside rather thickly clothed with ferruginous hairs. The tarsi are black, and the soles are with ferruginous hairs. Length 17 ½ lines (37 mm). Hab. Guatemala (Coll. Deby).
