Kunaibidion giesberti sp. nov.

(Fig. 2)

Description. Head black. Frons opaque, microsculptured medially, with some irregularities (30×) on upper region. Genae finely punctate. Vertex microsculptured. Antennal tubercles distant at base. Eyes small, finely granulate. Upper ocular lobes with three rows of ommatidia separated by more than apices of antennal tubercles. Antennae black, reaching elytral apices at approximately middle of antennomere VII. Scape shiny with sparse punctures. Antennomere III without keels, with sparse bristles on inner side.

Prothorax black with deep anterior and posterior constrictions. Pronotum with three postmedial tubercles: two anterior and one median inconspicuous. Pronotum surface smooth and shiny. Sides of prothorax with a stripe of white pubescence, longitudinal, narrow, close to prosternum but not reaching anterior limit of prothorax. Prosternum shiny. Prosternal process with white pubescence.

Scutellum covered by white pubescence. Elytra black, shiny, with a yellow medial band; oblique from suture to margin; surface very shiny, with a single row of piliferous punctures close to suture. Elytral apices rounded.

Legs black; femora pedunculate, and clavate; meso- and metatibiae curved. Thoracic sterna and urosternites black. Mesosternum glabrous medially with white pubescence laterally, and on mesosternal process. Lateral– posterior areas of mesosternum covered with white pubescence. Urosternites shining.

Measurements in mm, holotype male. Total length, 9.5; prothorax length, 2.8; greatest width of prothorax, 1.6; elytron length, 5.4; humeral length, 2.0.

Etymology. The species name is an homage to the late Edmund F. Giesbert (1931–1999), who described the genus Kunaibidion.

Type material. Holotype male, FRENCH GUIANA, “road to” Kaw, km 40, 15–16.II.2005, F. T. Hovore col. (CASC).

Remarks. Giesbert (1998: 51) placed Kunaibidion as “will run to Part IV in Martins (1967) key to the tribe Ibidionini,” that is, currently placed in the subtribe Compsina of tribe Neoibidionini. Giesbert also considered that the genus “is here provisionally placed” for eyes finely granulate.

The genus must be provisionally placed in Neoibidionini.
