( Figs. 1‑4 View Figures1-8 )

Description: Male: Integument mostly brownish, slightly darker on some areas; mouthparts, apex of antennal tubercles, yellowish-brown; scape dark reddish-brown; pedicel yellowish-brown basally; antennomeres III-X reddish-brown on basal ¾ (more yellowish-brown depending on intensity of light), gradually darkened on distal quarter, especially on III-VII; prosternal process gradually reddish-brown toward apex; elytra reddish-brown on anterior third, gradually yellowish-brown toward apex, except dark brown triangular area on anterior sixth around scutellum, oblique dark brown band dorsally, from about apex of anterior quarter to before middle (together V-shaped), slightly distinct, irregular brown macula dorsally after middle, and dark brown punctures on anterior ¾; femora reddish-brown, slightly darkened toward apex; tibiae with basal dark reddish-brown ring, reddish-brown (more yellowish-brown depending on intensity of light) on wide central area, and slightly, gradually darkened toward apex; tarsi reddish-brown except blackish apex of claws. Pubescence somewhat golden; erect setae pale yellow.

Head: Frons narrow, vertical; pubescence not obscuring integument. Antennal tubercles elevated, close to each other, separated by deep sulcus, with apex rounded, more distinctly elevated; pubescence not obscuring integument, distinctly sparser along dorsal surface. Vertex minutely, sparsely punctate, gradually coarser, denser toward prothoracic margin (partially confluent close to prothorax); pubescence not obscuring integument, denser close to antennal tubercles and sides after middle of upper eye lobes, nearly glabrous close to prothorax (slightly bristly on some areas). Area behind upper eye lobes minutely, sparsely punctate toward inner margin, coarser, abundant on its central area, especially toward prothorax, finer, sparser toward lower eye lobe; pubescence abundant, not obscuring integument, except glabrous area close to prothorax, gradually sparser, present only close to eyes toward lower eye lobe; with a few long, erect setae close to eye. Area behind lower eye lobes finely, sparsely punctate, slightly transversely striate centrally; pubescent close to eye, gradually glabrous toward prothorax. Genae very finely, transversely striate on basal ¾ close to eye, smooth on distal quarter; with moderately sparse pubescence on basal ¾, glabrous on distal quarter. Gulamentum smooth except slightly rugose anterior area; with sparse pubescence laterally at about anterior half, more abundant close to eyes, and on slightly rugose area; rugose area with sparse, elongated erect setae. Postclypeus large, sub-horizontal, slightly convex and longitudinally sulcate close to frons, slightly inclined toward labrum; finely, moderately abundantly punctate on sub-horizontal area, except smooth central area, nearly smooth on remaining surface; with moderately long (especially toward anterior margin), nearly decumbent, abundant setae laterally, smooth centrally (this latter area gradually widened toward anterior margin). Labrum coplanar with anteclypeus at posterior third, gradually inclined toward anterior margin at distal ⅔; finely, moderately abundantly punctate, especially on posterior third; with long, erect, moderately abundant setae, absent close to anteclypeus,and fringe of short setae at anterior margin. Maxillary palpomere IV widened toward apex, but not distinctly securiform, with distal margin oblique. Inner margin of upper eye lobes large, rounded. Distance between upper eye lobes 0.27 times length of scape; distance between lower eye lobes ventrally, 0.61 times length of scape. Antennae 2.0 times elytral length, reaching elytral apex at about distal quarter of antennomere VII. Scape moderately coarsely, densely punctate (slightly rugose); pubescence not obscuring integument, nearly glabrous ventrally, interspersed with a few elongated, erect setae. Antennomeres with pubescence distinctly exposing integument; with a few elongated, erect setae at apex of III-X. Antennal formula based on antennomere III: scape = 0.87; pedicel = 0.14; IV = 0.98;V = 0.96;VI = 0.96;VII = 0.93;VIII = 0.86;IX = 0.77; X = 0.67; XI = 0.72.

Thorax: Prothorax 1.45 times wider than long (including lateral tubercles);lateral tubercles large,conical,placed at middle; anterior margin slightly narrower than posterior one. Pronotum with five distinct tubercles: one on each side of anterior half, nearly conical, higher than the others; one on each side of posterior half; another centrally, subelliptical, slightly sulcate longitudinally. Pronotal pubescence abundant, not obscuring integument, except on glabrous central tubercle and top of lateral tubercles of disc; anterior and posterior constrictions well-marked; central area, among tubercles, minutely, abundantly punctate (sparsely on central gibbosity); remaining surface nearly smooth. Sides of prothorax with abundant pubescence, partially obscuring integument, between anterior and posterior constrictions, sparsely pubescent on remaining surface. Prosternum sparsely pubescent close to procoxal cavities and laterally, with very sparse setae on remaining surface. Mesoventrite with pubescence distinctly exposing integument, glabrous laterally. Mesanepisternum and mesepimeron with pubescence denser than on mesoventrite. Metanepisternum and metaventrite with abundant pubescence not obscuring integument, except central, triangular area of metaventrite with pubescence distinctly sparser. Scutellum with pubescence obscuring integument.

Elytra: Coarsely, abundantly punctate on anterior third, gradually finer, sparser toward apex (lateral punctures aligned); pubescence abundant, partially obscuring integument; posterior third with elongated setae on margins; apex narrowly rounded (nearly triangular).

Legs: Profemora fusiform; meso- and metafemora clavate; pubescence not obscuring integument. Protibiae wider than meso- and metatibiae, somewhat curved from base to near apex, which is slightly wider; ventral side with pubescence not obscuring integument, interspersed with elongated erect setae; dorsal side with suberect setae, sparser on protibiae. Metatarsomere I longer than II-III together.

Abdomen: Ventrites with abundant pubescence,not obscuring integument, except on glabrous posterior area of I-IV, and nearly glabrous basal area of V; ventrite I slightly shorter than ventrite II; apex of ventrite V truncate.

Dimensions (mm): Total length, 19.30; prothoracic length, 2.40; posterior prothoracic width, 2.45; anterior prothoracic width, 2.30; maximum prothoracic width (between apices of lateral tubercles), 3.45; humeral width, 4.15; elytral length, 14.00.

Type Material: Holotype male from MEXICO, Oaxaca: Concepción Pápalo (2,275 m), 10.VII.1997, G. Nogueira col. ( CNIN).

Remarks: Novantinoe oaxaquena sp. nov. is similar to N. cristinae Santos-Silva & Hovore, 2007 ; N. hefferni Santos-Silva & Hovore, 2007 ; and N. payettei Santos-Silva & Le Tirant, 2016 by its general appearance, the elytra bicolourus, and the inner and outer apical projections of metafemora subequal in length and with the same shape. It differs from N. cristinae by the body slender (wider in males of N. cristinae ), head + prothorax slightly shorter than three times elytral length (slightly longer than twice elytral length in males of N. cristinae ), pronotal and elytral pubescence more abundant (sparser in N. cristinae ), elytral apex narrowly rounded (obliquely truncate in males of N. cristinae ), and profemora without short spines ventrally (present in males of N. cristinae ). The new species differs from N. hefferni by the head + prothorax slightly shorter than three times elytral length (2.5 times in N. hefferni ), elytra slightly narrowed toward apex (distinctly narrowed toward apex in N. hefferni ), elytral apex narrowly rounded (nearly acute in males of N. hefferni ). Novantinoe oaxaquena sp. nov. differs from males of N. payettei by the slender body (wider in N. payettei), scape slender (distinctly widened in N. payettei), and elytral apex narrowly rounded (with distinct spine at outer angle in N. payettei). The general appearance of the new species also resembles N. noguerai Santos-Silva & Le Tirant, 2016, but differs from it by the maxillary palpomere IV not distinct securiform (securiform in males of N. noguerai), scape slender (wider in N. noguerai), and elytral apex narrowly rounded (spiniform in N. noguerai). For comparisons, photographs of the holotypes of N.cristinae , N. payettei, N. noguerai, and N. hefferni are available in Bezark (2018).

Etymology: The epithet, oaxaquena, is a demonym alluding to the inhabitants of Oaxaca state, in Mexico, the locality where the specimen was collected.
