Crioprosopus iridescens Bates, 1880:74 (not White, 1853).

Redescription. Male: Length, 29 mm. Form large, integument reddish-brown, head and thorax castaneo-fuscus, antennal segments 1–6 black to dark castaneous, segments 7–11 gradually lighter, reddish-brown, femora reddishorange except apices and base gradually darker, tibiae and tarsi darker castaneous, elytra metallic green, finely, densely punctate from base to apex. Head with vertex glabrate, very sparsely punctate and bicarinate between eyes; palpi short, apical segment of maxillary pair impressed dorsally, apices of labial and maxillary pair subtruncate; antennal tubercles moderately elevated, apices angulate; antennae ¼ shorter than body, scape with basal ¼ longitudinally impressed, segments laterally carinate from apical ¼ of 3rd–11th, longitudinally impressed on both sides of carina on apical ¼ of 3rd, apical ½ of 4th, and entire length of 5th and 6th, dorsal surface slightly impressed on apical ½ of 3rd, and on segments 4–5, 3rd segment subequal to 1st, 4th subequal to 5th and shorter than 1st, 6th longer than 5th and shorter than 1st, 7th subequal to 5th, 8th and 9th shorter than 7th, 10th shorter than 9th, 11th subequal to 7th, scarcely appendiculate. Pronotum dull, inflated, broader than long (1.5 x as broad as long), laterally rounded, base arcuately impressed, disc densely, contiguously punctate, anterior half transversely impressed in middle, posterior half with two oblique, longitudinal impressions on both sides of middle, sides moderately, coarsely, contiguously punctate, dorsal median line finely punctate, anterior half of median line, narrow (0.4 x width of upper lobe interocular space), dilated abruptly at anterior margin, ante-medially with transversely oval dilation, post-medially with median line 2x wider than anterior median line, gradually dilated into a smooth, elongate-triangular area; prosternum densely, contiguously punctate, surface sparsely clothed with white, suberect, short hair; mesosternum with intercoxal process subequal to width of coxal cavity, subtuberculate, not obviously projected below base of coxae, sides densely clothed with short, appressed, silvery pubescence. Scutellum longer than wide, black, longitudinally impressed medially, acutely pointed apically. Elytra about 2.3 times longer than broad, sides slightly tapering; disc with two vague costae on each elytron, base with oblique, longitudinal impression at humeral angle, apices obliquely truncate. Legs with hind femora shorter than body. Abdomen with whitish, suberect, transparent hairs; 5th sternite with apex subtruncate.

Female: Not available for study.

Distribution. Guatemala.

Materials examined. GUATEMALA: Suchitepequez, Santa Barbara, 17 July 1993, P. Hubbell (1 male, FSCA). The following material is also considered to be this species: Guatemala: Zapote, 1890, D. Röder, F. Tippmann, Wein, Tippmann Coll. ’57, 213112 (1 male, USNM).

Note. According to Bates (1885), “ The two specimens from Zapote referred as female to White’s species prove to be of the same sex (male) as White’s typical example. They are nearly the same in colors as iridescens (male) and basileus (male); but C. championi (male) differs from both in the transversely ovate form of the thorax, the sides of which are strongly arcuated, without trace of lateral tubercles or conical protuberance. The antennae are also much shorter one fourth shorter than the body; length is 18 lines (or 38 mm)”. According to the above description, Crioprosopus championi Bates (male) can be separated from C. iridescens White (male) by the laterally ovate form of the thorax and the antennae being ¼ shorter than the body. The antennae of C. iridescens and C. gaumeri Bates are longer than their body.
