( Figures. 2E View FIGURE 2 , 3E View FIGURE 3 , 4E View FIGURE 4 , 6D View FIGURE 6 , 12C–D View FIGURE 12 )

Diagnosis. 1) Preapical area of posterior pronotal process enlarged in three humps; (2) in dorsal view, posterolateral area projected beyond humeral angles; (3) s crossvein absent; (4) style with margin dorso apical strongly curved; (5) pronotum with yellow nodes.

Description. Color and sculpture. General color black; eyes yellow, ocelli black; pronotum black contrasted with yellow areas; legs and abdomen brown; head surface corrugated; head, pronotum, and legs covered with scattered yellow setae; pronotum with yellow nodes arranged irregularly. Head. Vertex with two parallel rugae extended from the anterior margin of vertex to the ocelli; suprantennal margin strongly punctate; frontoclypeus with numerous transversal lines, covered with yellow setae over apex and lateral margin ( Fig. 2E View FIGURE 2 ). Thorax. Pronotum. In lateral view sinuate, preapical part of posterior process, with depression behind humeral angles notably marked, followed by a small cone-shaped hump, posterior pronotal process gradually curved ( Fig. 3E View FIGURE 3 ); in dorsal view, posterolateral area rounded, distinctly projected laterally beyond humeral angles, pronotum abruptly narrowing in an acute apex ( Fig. 4E View FIGURE 4 ). Forewings. 1 st apical cell with distinctive macula, s crossvein absent ( Fig. 6D View FIGURE 6 ). Abdomen. Male. Aedeagus, ( Fig. 12C View FIGURE 12 ) margin dorsal of corona with denticuli; style ( Fig. 12D View FIGURE 12 ) in lateral view sinuate, margin dorsoapical of hook strongly curved. Female unknown.

Measurements (mm). Male. Total length: 4.8; pronotum length: 3.9; pronotum height: 1.06; head width: 1.53; head height: 1,19; distance between apices of humeral angles: 2.15.

Etymology. This species is named according to the country where the species was found.

Material examined. Holotype. Pinned. (♂ FSCA). French Guiana, 1 km S. Amazon Nature Lodge. 30 km SE Roura on Kaw Rd. , N 4032.961 ’ W 052012.830. 288m. MV light. 3/ 4-VI-2005. J. E. Eager & M. T. Messenger. Coll.

Comments. This and the previous species are the first records of the genus for French Guiana. This species is somewhat similar to N. curculionoida Sakakibara but differs in the pronotal color and sculpture, pronotal shape, and forewing lacking the s crossvein. In N. curculionoida the pronotum has elevated yellow discontinuous lines; in N. guianensis sp. nov. the pronotum has elevated yellow irregular discontinuous nodes. Contrasted with N. curculionoida but similar to the species described below, the lateral pronotal profile is not continuously convex or rounded in N. guianensis , but has three distinctive cone-shaped humps.
