Description. Female. Integument metallic dark blue. Distal half of clypeus yellowish. Antennomeres III–XI gradually more light brown.

Head. Vertex with some sparse and shallow punctures, with sparse, erect long setae; frons and antennal tubercles smooth except some punctures, with short and dense setae on sides of frons; basal half of clypeus rugose, with long yellowish setae; genae short, apex rounded; distance between upper eye lobes subequal to width of one upper lobe. Gulamentum smooth. Antennae reaching elytral apex at antennomere X, antennomeres finely punctate, with short and dense yellowish setae, interspersed with longer setae, mainly at apex; inner face of antennomeres III–X with long, dense black setae; scape slightly curved at base, progressively dilated to apex, not granulate at inner face; antennal formula (ratio) based on length of antennomere III: scape = 0.96; pedicel = 0.08; IV = 0.87; V = 0.81; VI = 0.79; VII = 0.77; VIII = 0.73; IX = 0.67; X = 0.58; XI = 0.67.

Thorax. Prothorax transverse, 1.13 times as wide as long (including lateral tubercles); with anterior and posterior constriction; lateral tubercles wide at base, acute at apex, directed upward. Pronotum with five gibbosities: two larger, not notably elevated, subcircular, placed on each side of anterior half; two subrounded, placed on each side of posterior half, subfused with anterolateral one; another elongate, slightly elevate, placed medially. Disc of pronotum with very fine transverse wrinkles; remaining surface shiny, smooth; with long and sparse whitish setae. Prosternum with transverse sulcus, smooth, with long and sparse whitish setae on anterior margin, glabrous at rest of surface; prosternal process with apex truncate; width at narrowest point equal to 1/6 of procoxal cavity width. Mesoventral process emarginated at posterior margin, with apex slightly narrower that mesocoxal cavity. Metaventrite finely punctate, each puncture with long, erect whitish seta. Scutellum with fine and dense pubescence, apex truncate. Elytra gradually narrowed to apex, 4.25 times as long as prothorax; with coarse deep punctation, arranged in five rows, from humerus to midlength of each elytron, and one, between sutural row and antecedent, from humerus to anterior third; with short, erect, sparse setae; humeri obliquely truncate, with dentiform projection; apex of elytra obliquely truncate, with long spine at outer angle and small dentiform projection at inner angle. Legs with long, sparse whitish setae. Femora subfusiform; more linear toward metafemora; meso- and metafemora with long outer spine; apex of metafemora with triangular projection at inner margin.

Abdomen. Ventrites finely and sparsely punctate, punctures denser laterally; with both, short and long, sparse setae, denser laterally and on distal ventrites; apex of ventrite V truncate.

Dimensions (mm). Holotype female. Total length, 16.4; prothoracic length, 2.7; basal prothoracic width, 2.1; distal prothoracic width, 1.8; widest prothoracic width (between apices of lateral tubercles), 3.0; humeral width, 3.1; elytral length, 11.5.

Type material. Holotype female from ECUADOR, Sucumbíos (prox. El Reventador, trilha da alegada “ Caverna Mágica ”, 0.024843°, -77.509254°, alt: 1367 m), 24.VI.2018, A. Giupponi, A. Kury & M. Medrano col. ( QCAZ).

Etymology. Latin, “vivida”, feminine = alive. Allusive of our hope for the restoration of the Museu Nacional/ UFRJ (MNRJ, Rio de Janeiro, Brazil). Despite the great tragedy that hit the Museu Nacional, it will remain alive. “O Museu Nacional vive!”

Remarks. Novantinoe vivida sp. nov. is similar to N. peruviensis (Villiers, 1959) ( Fig. 28 ) and N. rileyi Santos- Silva & Hovore, 2007 ( Figs. 26–27 ). It differs from N. peruviensis as follows: scape finely punctate; humeri subsmooth (without evident tubercles); metaventrite finely punctate; femora unicolorous; and spine at apex of meso- and metafemora longer (longer than the width of the femora at apex). In N. peruviensis , the scape is coarsely punctate, the humeri are tuberculate, the femora are bicolorous, and the spine at apex of meso- and metafemora is shorter (shorter than the width of the femora at apex). The new species differs from N. rileyi by the palpomeres and legs dark (light-orange in N. rileyi ), lateral tubercles of the prothorax are wider and larger at base (finer and longer in N. rileyi ), and the median gibbosity of the pronotum is slightly elevated (clearly elevated in N. rileyi ). The new species also differs from N. lingafelteri Santos-Silva & Hovore, 2007 by the scape finer and progressively dilated to the apex (scape wider and more strongly dilated at distal half in N. lingafelteri ), disc of the pronotum with fine transverse wrinkles (without wrinkles in N. lingafelteri ), and the humeri with a dentiform projection (without dentiform projection in N. lingafelteri ). Novantinoe vivida sp. nov. differs from N. wappesi Santos-Silva & Hovore, 2007 by the pronotum with very sparse punctures, femora unicolorous, and the meso- and metafemora with long spine. In N. wappesi , the pronotum is densely punctate between the gibbosities, the femora are bicolorous, and the spine of meso- and metafemora are slightly projected.
