description: Pteroplatus caudatus sp. nov.
(Fig. 4)
Head opaque with integument black. Frons (40 x) finely punctate. Vertex with sparse black pubescence, more visible on the occiput. Eyes finely granulate. Upper ocular lobes (width = 0.21 mm) separated by a distance of 3.5 times lobe’s width (distance between lobes = 0.7 mm). Antennae (male) black, reaching the apical fourth of the elytra. Scape thickened toward the apex, densely, finely punctate, covered by short black hairs, with a few intermixed long hairs; length subequal to that of antennomere III. Antennomeres III-VI with dense tufts of black hairs on the inner margins, apically thicker and longer in the direction of VI. Antennomeres VII-X with length gradually decreasing. Antennomere XI as long as antennomere VIII.
Prothorax black, wider than long, the anterior and posterior constriction similar in length. Pronotum with two orange integumental spots covered by golden-yellow pubescence, positioned very close to the anterior rim and extending past the middle, closer to the margin than the midline; two very small spots behind the larger ones at the basal margin. Pronotal midline glabrous, discretely elevated from near basal margin to the apical margin. Prothorax laterally punctate. Prosternum punctate with sparse hairs.
Elytra black, opaque; humeri with small orange spot; apical fifth yellow. Dorsum of elytra with two costae, the more evident outer costae reaches from the humeral area to the posterior part of the apical orange marking, the other, closest to the suture, is much less visible and evanescent in apical third. Surface of elytra impunctate but with discrete grooves. Elytra apices oblique with sutural angle projected and obtusely rounded.
Legs black. Profemora fusiform; meso- and metafemora pedunculate and clavate. Ventral surface of body black with sparse hairs. Thoracic sterna opaque, finely punctate; urosternites glabrous, punctures more evident.
Measurements, in mm, holotype male. Total length,11.8; prothorax length, 1.9, greatest width of prothorax, 2.5; elytron length, 9.2; humeral width, 3.3.
Type material. Holotype male, COLOMBIA, Cundinamarca: Ubaque (Vereda San Antonio, 4º29’06”N, 73º53’24”W, 1867 m), 4.X.1997, C. Bejarano & J. Diaz col. (UNAB).
Etymology. Latin, cauda = caudate; alluding to the extremities of elytra.
Discussion. Pteroplatus caudatus sp. nov. is distinguished from other species of the genus by the pronotal spots and by having the apical fifth of the elytra orange. Most Pteroplatus species have a longitudinal black stripe, in the center of the pronotum, with a few having the pronotum all black or yellow. Generally, the elytra in Pteroplatus have black apices.
