( Figures 10–13 View Figures 1–13. 1–6 )

Description. Integument brown; abdomen dark-brown; the following black: margin of antennal tubercles around antennal sockets; apex of mandibles; most of palpi; part of club of scape; distal fourth of antennomere III; distal third of antennomeres IV–V; apex of femora; base and apex of tibiae; tarsomeres III–V.

Head. Frons densely microsculptured; pubescence most brownish, yellow-whitish close to clypeus and around coronal suture (more yellowish near antennal tubercles), laterally with narrow yellowish band from clypeus to antennal tubercles. Vertex densely microsculptured; pubescence brownish, with yellow band around coronal suture, from area between antennal tubercles to level of posterior edge of eyes, and narrow band behind and in front of part of superior ocular lobes. Area behind eyes and genae with brownish pubescence, mixed by white-yellowish pubescence, mainly behind narrow yellow band of superior ocular lobes and distal portion of genae. Distance between superior ocular lobes equal to 0.15 times length of scape; distance between inferior ocular lobes equal to 0.30 times length of scape. Antennae as long as 1.7 times elytral length; reaching elytral apex at apex of antennomere VIII; club of scape large, with pubescence most blackish; antennomeres III–IV with basal ring of whitish pubescence (wider on IV); antennomere VI with whitish pubescence on basal two-thirds; antennal formula based on antennomere III: scape = 1.36; pedicel = 0.14; IV = 0.86; V = 0.53; VI = 0.45; VII = 0.31; VIII = 0.29; IX = 0.29; X = 0.25; XI = 0.26.

Thorax. Pronotum with row of deep, coarse punctures on base, some smaller punctures on basal fourth, and one/two coarse punctures on each side (inside base of yellow band); laterally, from base to apex, large band of yellow pubescence, narrowed towards anterior edge; remaining surface with brownish pubescence. Lateral sides of prothorax coarsely, sparsely punctate (distinctly sparser on basal half); pubescence brownish. Prosternum and prosternal process with yellowish pubescence (former laterally mixed by whitish pubescence). Mesosternum and mesosternal processes with yellow-whitish pubescence (more whitish depending of angle of light). Mesepisternum with yellowish pubescence close to margins, centrally brownish mixed by whitish pubescence. Metasternum laterally with yellow-whitish pubescence (more whitish depending of angle of light), centrally brownish. Scutellum with yellow pubescence on central triangular area of base and distal margin on each side of longitudinal sulcus; remaining surface with brownish pubescence. Elytra. Coarsely, deeply, moderately abundantly punctate on basal half (mainly on circum-scutellar region), finely, sparsely punctate on distal half; apex largely obliquely truncate, with large spine at outer angle, and rounded sutural angle; pubescence most brownish, with the following yellow on each elytron: sub-circular wide band on basal fourth, starting on base close to humeri (pubescence sparser towards apex); wide oblique band starting about middle near lateral margin, reaching sutural margin, and following it for a short space; ocellar macula on distal third; several small spots from base to oblique band at middle.

Abdomen. Pubescence most brownish; urosternites I–IV laterally with wide transverse band of white-yellowish pubescence, sub-circular spot of pubescence of same color between band and lateral margin, and narrow band also white-yellowish along distal margin (pubescence more whitish depending of angle of light); center of urosternite V variegated by white-yellowish pubescence. Legs. Femora, from base to about distal third of club, with white-yellowish (more whitish depending of angle of light); tibiae with white-yellowish (more whitish depending of angle of light), distally with blackish pubescence; tarsomeres I variegated by white-yellowish pubescence (more whitish depending of angle of light); metatarsomere I 1.4 times as long as II–III combined.

Dimensions in mm (male). Total length, 13.3; length of prothorax at center, 2.4; anterior width of prothorax, 2.5; posterior width of prothorax, 3.4; humeral width, 5.0; elytral length, 9.2.

Type material. Holotype male from BOLIVIA, La Paz Department: Caranavi (1300 m), 1–25.XII.2007, local collector ( MZSP).  

Etymology. This species is dedicated to our colleague Robert Vigneault, a specialist in the longhorn beetles of Quebec and also a very important collaborator with both our institutions.

Remarks. Carneades vigneaulti   differs from the other species of the genus by distinct yellow bands and spots contrasting with remaining surface of elytra.
