Scutellum with abundant whitish pubescence partially obscuring integument. Elytra.

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.

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 .
