( Figs. 124–125 )

Description. Male: Length, 27 mm. Form medium-sized, parallel-sided; integument dark reddish-brown; antennae with scape dark brownish, segments 2–3 darker reddish-brown, 4th–11th lighter in color with apices of 3rd–7th darker; elytra iridescent yellowish metallic green; legs lighter reddish-brown with apices of femora, and bases and apices of tibiae darker. Head with vertex sparsely punctate and bicarinate between eyes; front obliquely, transversely impressed, each side with a pit, median line, extending onto vertex between a swollen area between eyes; palpi with apices of labial and maxillary pair subtruncate, apical segment of maxillary pair impressed dorsally; genae small, sparsely punctate; antennal tubercles with apices obtusely angulate; antennae longer than body, slightly expanded externally from segments 6–10, scape with basal ¼ longitudinally impressed, segments 3–11 laterally carinate from apical 1/3 of 3rd, dorsal surface of 3rd and 4th slightly impressed, 3rd segment longer than 1st, 4th shorter than 3rd and subequal to 1st, 5th longer than 4th, 6th subequal to 5th, 7th longer than 6th and subequal to 3rd, 8th and 9th subequal to 1st, 10th shorter than 9th, 11th longest and scarcely appendiculate at apical ¼. Pronotum dull, inflated, broader than long (1.55 x as broad as long), sides obtusely angulate, base arcuately impressed, disc convex, coarsely, densely, confluently punctate, anterior half with depression near apex of lateral angle, and posterior half with an oblique, longitudinal impunctate depression on each side of middle, and another oval depression between oblique depression and lateral tubercle; dorsal median line smooth, finely punctate, anterior half of median line, narrow (0.46 x width of upper lobe interocular space), dilated abruptly at anterior margin, ante-medially with rhombiform dilation near middle, postmedially with median line 2–fold wider than anterior median line, gradually expands posteriorly into a smooth, elongate-triangular area to basal margin; prosternum with transverse, coarsely, densely, confluently punctate area on each side above coxae, anterior margin and narrow median line smooth, surface sparsely clothed with golden, suberect, short hair, intercoxal process glabrous. Scutellum triangular, as long as wide, dark brownish with sides darker. Elytra parallel-sided, about 2.3 times longer than broad, distinctly margined laterally; disc polished with two distinct costae on each elytron, surface finely reticulated, base wrinkled, transversely rugulose at sutural margin and near apex, apices obliquely subtruncate, rounded at sutural angle. Abdomen densely clothed with whitish, subdepressed hairs; fifth sternite with apex subtruncate.

Female: Unknown.

Etymology. This species is named after the country of origin where collected.

Type. Honduras: Hotjtolz? Inban? Leg. Tippman Collection ’57, 213112 (1 male, USNM). Holotype deposited in USNM.

Note. This single male from Honduras has the general appearance of Crioprosopus tricolor (Waterhouse) (male) in coloration and size, and resembles C. gaumeri Bates (male) with the sides of pronotum that are rounded and elytra that are more parallel-sided. The pronotal disk is convex without a broad impression in middle of anterior half, and the scutellum is triangular as in C. tricolor . The basal ½ of elytra are more rugose than C. gaumeri , with two distinctive costae on each elytron. This male is also smaller (27 mm) than C. gaumeri (33–40 mm), and the elytra are slightly more elongate (2.3 x longer than broad).
