Wide central area of postclypeus with sparse whitish setae and one long, erect seta on each side close to frons, setae dark brown basally, gradually yellowish toward apex, and a few long, erect yellowish setae on each side close to anteclypeus. Sides of postclypeus glabrous. Posterior third of labrum with sparse, decumbent yellowish setae, with long setae of same color directed forward interspersed, one very long seta on each side, setae dark brown basally, gradually yellowish toward apex, and a few moderately long, erect dark brown setae interspersed; central region glabrous; anterior area with abundant, short, bristly yellowish-brown setae; sides with somewhat abundant whitish setae. Gulamentum smooth, glabrous, except anterior region depressed and with sparse yellowish-white pubescence. Distance between upper eye lobes 0.32 times distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.70 times distance between outer margins of eyes. Antennae 3.90 times elytral length, reaching elytral apex at basal quarter of antennomere V. Scape, pedicel, and antennomeres III–XI with abundant whitish pubescence not obscuring integument; pedicel and antennomere III with a few short, thick, erect dark-brown setae ventrally. Antennal formula based on length of antennomere III: scape = 0.77; pedicel = 0.09; IV = 0.96; V = 0.84; VI = 0.86; VII = 0.82; VIII = 0.86; IX = 0.79; X = 0.52; XI = 0.79.

Thorax. Prothorax wider than long; with narrow transverse sulcus close to anterior margin; sides slightly rounded and slightly widened from anterolateral angles to lateral tubercles, subparallel-sided from lateral tubercles to posterolateral angles; lateral tubercles located on posterior quarter, with acute apex directed backward. Pronotum and sides of prothorax with abundant whitish pubescence not obscuring integument, except glabrous anterior sulcus; with a few long, erect dark brown setae laterally behind lateral tubercles. Prosternum with somewhat sparse whitish pubescence. Prosternal process distinctly narrowed centrally, narrowest area 0.07 times procoxal width. Mesoventral process very narrow, parallel-sided from its basal quarter, narrowest area 0.06 times mesocoxal width. Ventral surface of meso- and metathorax with somewhat abundant whitish pubescence not obscuring integument laterally, pubescence sparser on central area. Scutellum with abundant whitish pubescence partially obscuring integument.

Elytra. Abundantly, coarsely, somewhat shallowly punctate on anterior 2/3, punctures sparser and finer on posterior quarter; apex slightly truncate and oblique; with abundant whitish pubescence not obscuring integument, pubescence slightly denser on posterior third. Legs. Profemora fusiform, distinctly wide; mesofemora pedunculateclavate, with club about as wide as profemoral club; metafemora gradually widened from base to near apex, with femoral club not distinctly separated from peduncle and narrower than mesofemoral club; all femora with abundant whitish pubescence not obscuring integument. Tibiae with somewhat abundant whitish pubescence not obscuring integument, except bristly yellowish-brown pubescence on posterior third of ventral surface, and somewhat abundant, thick, short, erect dark-brown setae on dorsal surface of posterior third of mesotibiae. Dorsal surface of tarsi with somewhat abundant whitish pubescence not obscuring integument; metatarsomere I 1.5 times longer than II–III together.

Abdomen. Ventrites with somewhat abundant whitish pubescence not obscuring integument, except glabrous apex of ventrites 1–4; posterior quarter of ventrite 5 with long, erect dark-brown setae interspersed; ventrite 5 wide, slightly longer than ventrite 4; apex of ventrite 5 slightly emarginate centrally.

Female ( Figs 8–9 ). Similar to male, differing by the antennae slightly shorter, 3.3 times elytral length, reaching elytral apex slightly after middle of antennomere V, and ventrite 5 distinctly narrowed toward apex, and slightly shorter than 3–4 together.

Variation. Central area of pronotum with large Y-shaped brownish macula; femora entirely brownish orange; abdominal ventrites brownish orange, except dark brown anterocentral area of ventrites 1–3.

Dimensions (mm) (Holotype male/ paratype females). Total length, 3.75/4.30–4.35; prothoracic length, 0.70/0.75–0.80; anterior prothoracic width, 0.80/0.90–0.90; posterior prothoracic width, 0.85/0.95–0.95; maximum prothoracic width, 1.05/1.15–1.15; humeral width, 1.15/1.35–1.35; elytral length, 2.50/2.90–2.85.

Type material. Holotype male from MEXICO, San Luis Potosi: Hwy. 57, 12 mi. NE Villa Hidalgo , 4900’, 10.IX.1982, C. & L. O’Brien & G. Wibmer leg. ( FSCA) . Paratypes — 2 females, same data as holotype (1, MZSP, formerly FSCA; 1 FSCA).

Etymology. We are pleased to name this species in honor of Felipe Noguera (Estación de Biología Chamela, Instituto de Biología, Universidad Nacional Autónoma de México, Mexico) for his contribution to the study of Cerambycidae .

Remarks. Urgleptes noguerai sp. nov. is similar to U. chamaeropsis (Fisher, 1926) (see photographs on Bezark 2023, Devesa & Barro 2019, and Lingafelter et al. 2023), but differs by the scape stouter, maximum diameter slightly wider than twice basal diameter of antennomere III (more slender, with maximum width slightly narrower than twice basal diameter of antennomere III in U. chamaeropsis ), elytral punctures slightly contrasting with integument and shallower (distinctly contrasting with integument and deeper in U. chamaeropsis ), narrowest area of mesoventral process distinctly narrower than 0.1 times width mesocoxal width (about 0.25 times mesocoxal width in U. chamaeropsis ), and metatarsomere I distinctly longer than II–III together (as long as II–III in U. chamaeropsis ). Moreover, U. chamaeropsis is known only from the Bahamas and Cuba, and the new species is from Mexico.
