Pteroplatus pallidicolor sp. nov.

( Fig. 5 )

Head with tegument black and opaque. Frons (40 x) punctate on sides. Vertex with sparse, black pubescence. Eyes finely granulate. Upper ocular lobes (width = 0.2 mm) separated from one another by 3.5 times the width of a lobe (distance between lobes = 0.7 mm). Antennae (male) black, reaching the apical fourth of the elytra. Scape thickened toward the apex, finely, densely punctate, covered by short, black hairs, with a few much longer hairs; longer than antennomere III. Antennomeres III-VI with tufts of dense black hairs on the inner margin apically, gradually thicker and longer in the direction of VI. Antennomeres VII-IX with length gradually decreasing. Antennomeres X and XI missing.

Prothorax reddish-yellow, except on anterior border of the underside, and perimeter of the procoxa. Pronotum with four dark spots: very small ones close to the anterior margin; the others black and larger, close to the basal edge. Pronotal surface opaque, smooth in the center and with very sparse hairs laterally. Sides of prothorax smooth. Prosternum punctate with sparse, white hairs. Scutellum black.

Elytra entirely yellow with contrasting dark punctures; outer costa more projected than the inner. Elytral extremities rounded.

Thoracic sterna black. Urosternites reddish-black.

Measurements, in mm, holotype male. Total length,13.0; prothorax length, 2.0, greatest width of prothorax, 2.5; elytron length, 10.0; humeral width, 3.4.

Type material. Holotype male, PERU, Cajamarca: Jaen, 8.X.1964, Korytkowski col. ( MZSP).

Etymology. Latin, pallidus = pallid; color = color; alluding to the color of elytra.

Discussion. Pteroplatus pallidicolor sp. nov is distinguished from P. nigriventris Breme, 1844 , described from Colombia, by the two black spots close to the base of the pronotum, and by the black scutellum. In P. nigriventris , the pronotum has three longitudinal black stripes, one central and one on each side and scutellum yellow.
