Estoloides nayeliae sp. nov. ( Figs 72–75 )

Description. Female. Integument dark brown, almost black; base of gulamentum dark reddish brown; basal half of antennomeres III–XI dark reddish brown, lighter from V.

Head. Frons and vertex finely, moderately sparsely punctate, widely, longitudinally depressed from clypeus to prothoracic margin centrally; with yellowish brown pubescence obscuring integument, with suberect, curved white setae interspersed, except narrow yellowish white band lining inner side of eyes, carina-shaped along upper eye lobes; with long, erect, brown setae close to lower eye lobes. Area behind upper eye lobes with yellowish brown pubescence obscuring integument. Area behind lower eye lobes tumid, microsculptured close to eye, finely, confluently punctate on band close to tumid area, nearly smooth toward prothorax; tumid area with dense, yellowish brown band close to eyes, wide band with yellowish brown pubescence adjacent to tumid area, and wide, glabrous band between them (on right side the pubescent bands are connected by another pubescent band near gena; left side entirely glabrous from base of lobe to apex of gena); with long, erect yellowish brown setae on tumid area. Antennal tubercles with yellowish brown pubescence obscuring integument, with a few erect brown setae interspersed. Median groove distinct from clypeus to prothoracic margin. Genae very finely transversely striate close to eye, microsculptured toward smooth apex; with yellowish brown pubescent band close to eye and toward ventral side, with a few, erect brown setae toward ventral side. Gulamentum smooth and glabrous, except area close to mentum with yellowish brown pubescence obscuring integument, with a few long, erect yellowish brown seta interspersed. Labrum convex, finely, sparsely punctate; with long, erect yellowish brown setae laterally, and fringe of yellowish brown setae at distal margin. Distance between upper eye lobes 0.6 times length of scape (2.6 times width of one lobe); in frontal view, distance between lower eye lobes 1.07 times length of scape. Antennae 1.7 times elytral length, reaching elytral apex at distal third of antennomere VIII. Scape gradually enlarged from base; with yellowish brown pubescence obscuring integument, and sparse, yellowish setae interspersed ventrally. Antennomeres III–XI with white pubescence partially obscuring integument on basal area with light integument, yellowish brown on remaining surface; antennomeres III–X with long, erect yellowish white setae ventrally, gradually shorter and sparser toward X. Antennal formula (ratio) based on length of antennomere III: scape = 0.65; pedicel = 0.15; IV = 0.95; V = 0.72; VI = 0.68; VII = 0.60; VIII = 0.52; IX = 0.48; X = 0.40; XI = 0.34.

Thorax. Prothorax, maximum width 1.6 times wider than long (including lateral tubercles); lateral tubercles large, placed slightly before middle, with apex acute. Pronotum with three large, well-marked gibbosities, one centrally, subelliptical, from apex of basal sixth to after middle, one on each side of distal half, subcircular; moderately coarsely, abundantly punctate, smooth on gibbosities; with wide, central white pubescent band, from base to apex, distinctly widened on area of central gibbosity, carina-shaped from apex of central gibbosity to distal margin; remaining surface with yellowish brown pubescence obscuring integument, less so on large basal area each side of white pubescence; with long, erect, sparse pale yellow setae laterally. Sides of prothorax with yellowish brown pubescence obscuring integument, with long, erect, sparse pale yellow setae interspersed. Prosternum with yellowish brown pubescence partially obscuring integument, less so centrally. Prosternal process centrally sulcate; with bristly, yellowish brown pubescence, partially obscuring integument. Ventral side of meso- and metathorax with yellowish brown pubescence partially obscuring integument (more yellowish white on wide central area of metaventrite), except mesoventrite base nearly smooth centrally. Scutellum with yellowish brown pubescence obscuring integument close to margins, nearly smooth centrally. Elytra. Moderately coarsely, abundantly punctate on basal quarter, gradually finer and sparser toward apex; with oblique, wide, white pubescent band obscuring integument, from area near humerus to near middle of suture (gradually indistinct toward epipleura), distinctly narrower to apex along suture; remaining surface with yellowish brown pubescence obscuring integument; with short, somewhat thick, suberect black setae throughout; apices slightly rounded (nearly truncate). Legs. Femora with yellowish brown pubescence nearly obscuring integument, with small, subcircular glabrous areas interspersed, especially on meso- and metafemora.

Abdomen. Ventrites with yellowish brown pubescence partially obscuring integument, yellower on narrow band at apex of ventrites I–IV. Distal third of ventrite V centrally depressed; distal margin concave.

Dimensions (mm). Total length, 12.87; prothoracic length, 2.30; basal prothoracic width, 2.65; distal prothoracic width, 2.52; maximum prothoracic width (between apices of lateral tubercles), 3.69; humeral width, 4.27; elytral length, 8.82.

Type material. Holotype female from MEXICO, Puebla: 12 km NW Tehuitzingo (1220 m), 04.VII.1992, C. L. Bellamy col. ( FSCA).

Etymology. Named for Nayeli Gutiérrez, currently a graduate student at UNAM, Mexico City, Mexico who, after completing her graduate degrees, plans to study New World Cerambycidae professionally. Nayeli was also very helpful in providing needed information, requested by the authors, for this paper.

Remarks. Estoloides nayeliae sp. nov. resembles E. flavoscutellaris Galileo et al., 2016 , by its wide body and prothoracic shape, but differs as follows: pronotum and elytra marked with white pubescent bands; scutellum nearly glabrous centrally; the antennomeres with a notably wide, white pubescent basal ring, covering more than basal half, and ventral side of body lacking glabrous circular spots. In E. flavoscutellaris the pronotum and elytra lack white pubescent bands, the scutellum is densely pubescent throughout, basal ring of antennomeres with white pubescence restricted to base, and ventral side of body with small, abundant, circular glabrous spots.
