( Figs. 116–117 )

Description. Female: Length, 30–32 mm. Form large; integument shining, black, parts of head, antennae, tibia, femora and abdomen partially dark reddish-brown; thorax black, each side with a large yellowish spot not reaching the anterior margin, apex of lateral tubercles black; elytra with two, yellow, transverse fasciae with sutural and lateral margins narrowly darker; pubescence sparse, long, and erect; hairs shorter, pale, and dense at sides of meso- and metasterna, and abdomen. Head with palpi short, apical segments of labial and maxillary pair truncate at apex, both impressed dorsally; genae reddish at apices, finely, sparsely punctate; antennal tubercles with apices rounded to vaguely angulate; antennae extending about a ½ segment beyond elytra, scape rugose, finely punctate, carinate (or canaliculate) over basal ¾, segments 1–5 dark reddish brown, 6th–11th reddish, segments with dorsal and ventral surface longitudinally impressed (or canaliculate) on apical ¾ of 3rd and on segments 4–5, segments 5–11 laterally expanded at apices or serrate, 3rd segment longer than 1st, 4th shorter, each segment from 5th–7th subequal to 1st, 8th shorter than 7th, 9th subequal to or shorter than 8th, 10th shorter than 9th, 11th appendiculate, subequal to 1st or shorter. Pronotum broader than long (1.6 x as broad as long), sides with large, obtuse tubercles at middle, lateral surface of anterior half rounded; disc convex, glabrate, shining, sides at apical ½ sparsely, shallowly punctate, dorsal punctures very sparse, shallower than sides, basal ½ almost impunctate, pubescence at sides sparse, pale, long, erect; prosternum narrow, each side above coxae with transverse, rugulose, striate-punctate area, apical margin deeply impressed, pubescence moderately dense, pale, erect; mesosternum with intercoxal process subtuberculiform, produced below coxal cavity with blunt apex, abruptly, concavely declivous anteriorly, sides very finely clothed with short, silvery pubescence; metasternum with very fine, pale pubescent at sides, sparser, longer, erect hairs medially. Scutellum triangular, as long as wide, black, glabrous, impunctate, and acutely pointed apically. Elytra about 2.2 times longer than broad, glabrous, wrinkled and impressed below apex of scutellum, sides slightly tapering, punctures obsolete, pubescence limited to apices and lateral margin, otherwise obsolete; disc with a broad, yellow, transverse fascia at basal ½, which taper towards sutural margin, and another, yellow fascia behind middle; apices obliquely subtruncate, exterior angle obtusely dentate; lateral margin of elytra terminating at apex of exterior angle. Legs with hind femora not extending beyond body. Abdomen finely pubescent at sides, segments 1–4 glabrous in middle except for few erect hairs; 5th sternite broadly truncate at apex, shallowly emarginate medially.

Male: Unknown.

Etymology. This species is named after the Chiriqui province of Panama where the specimens were collected.

Types: Holotype, female, Panama: Chiriqui Prov.: 6 km S. Fortuna Dam, 15–18 April 1993, E. Giesbert (FSCA). Other paratypes, all from Panama: Chiriqui, 6 km S. Fortuna, 16, 17 April 1993, J. E. Wappes (1 female, ACMT); 15–17 May 1993, E. Giesbert (1 female, FSCA). Holotype deposited at FSCA.

Note. Crioprosopus chiriquiensis is a closely allied species to C. amoenus Jordan, which can be distinguished from amoenus by the darker coloration of the femora, metepisternum and abdomen, and the slightly shorter antennae, which extend not more than ½ segment beyond the elytral apices. Both C. amoenus and C. chiriquiensis have a scutellum that is triangular in shape. Its characteristics generally fit the description of C. saundersii ( White, 1853) ; however, the elytra of C. chiriquiensis are more parallel sided and less tapered, and the antennae are longer than in saundersii based on the photo shown (Bezark, 2014, id: 6142). Specimens of C. chiriquiensis have elytra with yellow fasciae that are continuous transverse bands, which are very narrowly darker at the sutural and lateral margins. The elytral discs are glabrous and very minutely punctate, and the punctures on the discs are discernable only at higher magnifications. The distribution of C. chiriquiensis is Panama, and C. saundersii White is a species from Mexico and Honduras.
