( Figs. 5‑8 )

Description: Female: Head dark brown dorsally, gradually brown toward prothorax; apex of antennal tubercles light reddish-brown; ventral side brown (slightly reddish depending on angle of light), gradually light reddish-brown toward prothorax; postclypeus reddish-brown except dark brown area close to frons;labrum reddish-brown (yellowish-brown depending on intensity of light); palpi reddish-brown; antennae reddish-brown, with dark brown ring on apex of some antennomeres; pronotum dark brown on wide central area, gradually reddish-brown toward anterior and posterior margins; prosternum reddish-brown anteriorly, gradually brown toward prosternal process and dark brown toward sides of posterior half; ventral surface of mesothorax brown centrally (more dark reddish-brown depending on intensity of light), dark brown laterally; metanepisternum and sides of metaventrite dark brown, and remaining surface of metaventrite reddish-brown; elytra reddish-brown except dark brown band along suture (anteriorly involving scutellum), and dark brown band along epipleura (both bands fused at apex); femora reddish-brown; tibiae yellowish-brown, gradually light reddish-brown toward apex; tarsi light reddish-brown; abdominal ventrites I-IV dark brown except slightly reddish central posterior half, and transverse yellowish-brown distal area; abdominal ventrite V dark brown on basal half, gradually dark reddish-brown toward apex. Pubescence yellowish-white, more golden on antennae, tibiae and tarsi.

Head: Frons narrow vertical; pubescence forming narrow transverse band on each side of center close to postclypeus, nearly absent on remaining surface. Antennal tubercles elevated, close each other, separated by shallow sulcus, with apex rounded, more distinctly elevated; with moderately sparse pubescence except glabrous apex. Vertex finely, moderately sparsely punctate between antennal tubercles and posterior margin of upper eye lobes, slightly coarser, denser toward prothorax; pubescence moderately sparse between antennal tubercles and middle of area between upper eye lobes and prothorax, then gradually shorter and sparser, absent close to prothoracic margin. Area behind upper eye lobes finely, moderately abundant punctate (punctures denser close to eye); with pubescence not obscuring integument close to eye, glabrous on remaining surface; with a few long, erect pale yellow setae.Area behind lower eye lobes nearly smooth on tumid area close to eye, finely, sparsely punctate toward prothorax; with sparse pubescence close to eye, glabrous on remaining surface. Genae with sparse pubescence along central area, glabrous close to lower eye lobe and apex. Gulamentum smooth except rugose-punctate anterior area; tumid between lower eye lobes, transversely sulcate close to rugose-punctate area; with sparse pubescence laterally at about anterior third and on rugose-punctate area, more abundant close to eyes, with a few elongated erect setae interspersed. Postclypeus large, sub-horizontal, slightly convex, finely, moderately sparsely punctate close to frons, inclined, smooth toward labrum; pubescent on punctate area (laterally with longer setae interspersed), glabrous anteriorly. Labrum coplanar with anteclypeus at posterior half, gradually inclined toward anterior margin (depressed on center of anterior half); with both short and elongated setae along transverse central area. Maxillary palpomere IV slightly, gradually widened toward oblique apex. Upper eye lobes moderately narrow. Distance between upper eye lobes 0.32 times length of scape; distance between lower eye lobes ventrally 0.64 times length of scape. Antennae 1.8 times elytral length, reaching elytral apex at distal third of antennomere VIII. Scape distinctly widened toward apex; moderately finely, abundant punctate on basal third, gradually finer, sparser toward apex; pubescence not obscuring integument; with a few long, erect setae dorsally on distal area. Antennomeres with pubescence distinctly exposing integument; with a few elongated, erect setae at apex of III-X; with very long, moderately abundant setae ventrally on III-XI. Antennal formula based on antennomere III: scape = 0.88; pedicel = 0.14; IV = 0.98; V = 0.96; VI = 0.93; VII = 0.88; VIII = 0.82; IX = 0.75; X = 0.65; XI = 0.65.

Thorax: Prothorax 1.28 times wider than long (including lateral tubercles); lateral tubercles large, conical, placed at middle; anterior margin as wide as posterior margin. Pronotum with five distinct tubercles, lateral ones together forming large gibbosity: one on each side of anterior half, nearly conical, higher than the others, with apex slightly directed sideward; one on each side of posterior half, with rounded apex; another centrally, elongated. Pronotal pubescence abundant, not obscuring integument, except on glabrous central tubercle; anterior and posterior constrictions well-marked; central area, among tubercles, finely, moderately sparsely punctate; remaining surface nearly smooth. Sides of prothorax with moderately abundant pubescence between anterior and posterior constrictions, not obscuring integument, sparsely pubescent on remaining surface. Prosternum sparsely pubescent close to procoxal cavities and laterally (especially on posterior half), with very sparse setae on remaining surface. Mesoventrite with pubescence not obscuring integument. Mesanepisternum with pubescence slightly denser than on mesoventrite and mesepimeron. Metanepisternum and metaventrite with abundant pubescence not obscuring integument, except central area of metaventrite with sparse pubescence (glabrous along central discrimen). Scutellum with pubescence obscuring integument.

Elytra: With five rows of coarse punctures (punctures absent on posterior third): one close to suture, reaching about posterior third; three more dorsally (innermost reaching only apex of anterior third; outermost reaching posterior third; central one slightly distinct after middle); one laterally, reaching about middle; pubescence abundant,not obscuring integument;with elongated setae laterally on posterior quarter; apex very narrowly rounded.

Legs: Profemora fusiform;meso- and metafemora clavate; pubescence not obscuring integument, with a few long, erect setae interspersed. Protibiae widened at posterior quarter; with sparse pubescence, denser ventrally on distal half. Metatarsomere I about as long as II-III together.

Abdomen: Ventrites with abundant pubescence, not obscuring integument (sparser centrally on posterior half of I-IV), except on glabrous posterior area of I-IV; ventrite I subequal in length to ventrite II; apex of ventrite V rounded.

Dimensions (mm): Total length, 17.40; prothoracic length, 2.35; posterior prothoracic width, 2.10; anterior prothoracic width, 2.10; maximum prothoracic width (between apices of lateral tubercles), 3.00; humeral width, 3.45; elytral length, 12.20.

Type Material: Holotype male from MEXICO, Oaxaca: Sierra de Juarez (850 m), 15.V.1998, G. Nogueira col. ( CNIN).

Remarks: The general appearance of Novantinoe fabiolae sp. nov. (female) is as that of N. hefferni (male). However, the scape ( Fig. 5 ) is abruptly widened toward apex and is not rugose. In N. hefferni , the scape (see in Bezark, 2018) is more gradually widened toward apex and is distinctly rugose. As we never saw this kind of sexual dimorphism in the other species of Neotropical Disteniinae , we believe that they belong to different species. Novantinoe fabiolae differs from N. cristinae by the denser pubescence on pronotum and elytra (sparse in both sexes of N. cristinae ); from N. payettei by the pronotal and elytral pubescence denser, and upper eye lobes narrower (pubescence sparse and upper eye lobes wider in N. payettei); from N. noguerai by the elytral punctures sparser and upper eye lobes narrower (punctures more abundant and upper eye lobes wider in N. noguerai); and from N. oaxaquena sp. nov. by the scape wider and not rugose (slender and rugose in N. oaxaquena ), and by the posterior third of the elytra more uniformly narrowed toward apex (somewhat rounded narrowed in N. oaxaquena ).

Etymology: This species is named after Fabiola Lopez C., the wife of Guillermo Nogueira collector of the holotype. This is in deep appreciation for her years of support of his work in entomology.
