Type species: Nasuconia curculionoida Sakakibara, 2006: 191 [sp. nov.; description, photograph]

Diagnosis. (1) Preapical area of posterior pronotal process evenly convex; (2) in dorsal view, posterolateral area weakly projected; (3) s crossvein present; (4) first valvula ventral interlocking device bent downward at mid-length of valvula; (5) second valvulae, with teeth in dorso apical margin; (6) pronotum with yellow longitudinal lines

Description. (Modified from Sakakibara 2006). Color and sculpture. Head black, pronotum dark brown humeral angles, thorax, legs, and abdomen, black; pronotum with longitudinal elevated yellow lines; frontolcypeus with surface corrugated. Head. Vertex without longitudinal lines. (Fig. 2D). Thorax. Pronotum. In lateral view, preapical area of posterior pronotal process low, almost evenly convex, with depression behind humeral angles, weakly marked (Fig. 3D); in dorsal view, posterolateral area of pronotum weakly projected laterally (Fig. 4D). Forewing. 1 st apical cell with distinctive macula; s crossvein present (Fig. 6C). Abdomen. Female. First valvula, (Fig. 13B) ventral interlocking device (VID) with one sinuous area at mid-length of valvula; dorsal margin of apex distinctly serrate, with blunt teeth (TOO) arranged irregularly; tip with denticles (DEN); two ventral preapical prominences (PP) present; pores scattered on valvula. Second valvulae, (Fig. 14B) dorsoapical margin with about five small blunt teeth of variable sizes; tip of valvula serrate in dorsal and ventral margin. Male Unknown.

Measurements (mm). Female. Total length: 7.05; pronotum length: 5.71; pronotum height: 1.71; head width: 2.56; head height: 2.24; distance between apices of humeral angles: 2.87.

Comments. The pronotal coloration and sculpture of N. curculionoida is similar to that of species of the lineosa- group, but this species differs in the following characters: frontoclypeus longer and curved downward; head narrower; ocelli larger; suprantennal margin tapering forwards and pronotal apex with elevated transverse carina. N. curculionoida differs from N. guianensis sp. nov. in the pronotal shape and sculpture, and longer frontoclypeus; and from N. yasuni sp. nov. in pronotal shape and sculpture and female genitalia characters. This species is newly recorded from French Guiana.
