Callisema jirouxi Santos-Silva, Bezark and Galileo , sp. nov.

( Figs. 1–4 )

Male. Integument dark brown, almost black; ventral side of head mostly reddish-brown; mouthparts yellowishbrown; antennae reddish-brown, darker on base of scape; legs dark reddish-brown, more brownish on some areas. Pubescence on head, prothorax and elytra yellowish-brown; pubescence on ventral side of meso- and metathorax, legs and abdomen yellowish-white.

Head. Frons rectangular, finely, abundantly punctate (punctures partially obscured by pubescence); pubescence dense, mainly close to clypeus and laterally, interspersed with long, erect, yellow setae laterally. Area between antennal tubercles and eyes with narrow, elongate, glabrous depression centrally; remaining surface densely pubescent, interspersed with long, erect, yellow setae. Vertex moderately coarsely, sparsely punctate; densely pubescent, except for glabrous, irregular area on each side of center, below upper eye lobes, and elongate area centrally close to prothoracic margin; with long, erect, yellow setae on area near eyes. Area behind eyes densely pubescent, gradually glabrous on area close to prothorax toward ventral side; with some long, erect, thick, black setae near lower eye lobes. Submentum moderately sparsely pubescent. Genae pubescent, except for glabrous, narrow area close to apex. Distance between upper eye lobes 0.10 times length of scape; distance between lower eye lobes in frontal view 0.75 times length of scape. Antennae 1.6 times elytral length, reaching elytral apex at apex of antennomere IX; scape with long, erect, sparse, thick setae, interspersed with long yellow setae; pedicel with long, thick, black, sparse setae ventrally; antennomere III with long, thick, black, sparse setae ventrally, interspersed with some long, yellow setae on basal third; antennomeres IV–X with long, thick, black, sparse setae ventrally, sparser toward antennomere X, mainly on IX–X; antennal formula (ratio) based on antennomere III: scape = 0.79; pedicel = 0.19; IV = 0.95; V = 0.80; VI = 0.72; VII = 0.69; VIII = 0.63; IX = 0.61; X = 0.56; XI = 0.55.

Thorax. Prothorax subcylindrical, wider than long (1.3 times wider than long, including lateral tubercles); sides with small, distinct, acute tubercle at middle. Pronotum coarsely, abundantly punctate (punctures partially obscured by pubescence); pubescence denser on three longitudinal bands (one centrally and one laterally one each side) and anterior third between bands; with thick, sparse, dark setae on anterior half. Sides of prothorax with punctures as on pronotum; pubescence partially obscuring punctures, denser toward ventral side. Prosternum and mesosternal process pubescent. Mesosternum pubescent, distinctly less conspicuous centrally. Mesosternal process longitudinally elevated (carina-shaped), dorsally shiny, glabrous; anterior margin slightly sloping toward mesosternum. Metepisterna pubescent. Metasternum coarsely, shallowly, sparsely punctate laterally; densely pubescent laterally, except for glabrous, small, areas surrounding punctures; pubescence sparser toward middle.

Elytra. Coarsely, sparsely punctate throughout; densely pubescent, except for small glabrous areas surrounding punctures; with thick, sparse, dark setae directed backward; apex obliquely truncate, with outer angle slightly projected and sutural angle rounded. Legs. Femora pubescent, except for small, somewhat distinct subglabrous areas surrounding punctures. Metatibiae with some thick, erect, dark setae.

Abdomen. Ventrites pubescent, denser laterally, except for small, abundant glabrous areas surrounding punctures; with long, sparse, erect, yellow setae; apex of ventrite V widely emarginate.

Dimensions (mm). Holotype male/ paratype male. Total length, 9.20/9.50; prothoracic length, 1.50/1.60; anterior prothoracic width, 1.65/1.70; basal prothoracic width, 1.65/1.70; largest prothoracic width (between apices of lateral tubercles), 1.95/2.10; humeral width, 2.45/2.60; elytral length, 6.70/6.85.

Type material. Holotype male ( CASC) and paratype male ( LGBC) from ECUADOR, Orellana: 16 km N Coca , 20.II.2004, F. T. Hovore col.

Etymology. The new species is named after Eric Jiroux, for his friendship and contribution towards the knowledge of Cerambycidae .

Remarks. Callisema jirouxi sp. nov. is similar to C. iucaua Martins & Galileo, 1996 but differs as pointed out in the key below.
