Holotype female. Length, 6.4 mm; width, 2.1 mm. Form small, elliptical, elongate; integument mostly light brown, with frons, parts of genae, pronotum, sides of prosternum, metaventrite, scape to third antennomere, apical third of fourth to ninth and apex of last two antennomeres, scutellum margins, apical half of pro- and mesofemora, maculae on elytra, base of ventrite 1 and sides of ventrite 5, dark brown to fuscous. Head with frons 1.1 times wider than long, convex, with median groove extending from clypeus to posterior part of head, base curved inward and carinate, with small, contiguous, shallowly punctures, and dense light grey pubescence partially obscuring integument; postclypeus very narrow, transversely carinate, with very long erect setae at sides; anteclypeus convex, glabrous; labrum with concave apex fringed with setae and with a transverse midline of long erect setae; vertex with moderately deep middle depression, with pubescence and punctures similar to that on frons; upper eye lobes narrow, 0.4 times distance of upper interocular space; lower eye lobes 1.3 times longer than genae; antennal tubercles moderately prominent, oblique, with small rounded projection on internal margin; antennae 2.6 times body length, reaching elytral apices at apex of fifth antennomere; scape wider centrally; antennomeres with fine, dense and short pubescence, light gray and with a row of suberect setae on the inner margin of antennomeres III–IV; antennal formula (proportion) based on length of antennomere III: scape = 0.80, pedicel = 0.06, IV = 0.92, V = 0.80, VI = 0.72, VII = 0.76, VIII = 0.88, IX = 0.92, X = 1, XI = 1.12. Prothorax 1.5 times wider than long; sides oblique, with acute tubercle projected backward on posterior third. Pronotum convex; narrow depression adjacent to the base with row of coarse punctures; surface with moderately dense, light grey pubescence, except for a kidney-shaped band on each side of middle line with bright pale golden pubescence, extending from basal depression to apical margin, continuing on head to the upper interocular space.

Diagnosis. Urgleptes martini sp. nov. is distinguished from all known Urgleptes species by the combination of the lateral band of dark brown pubescence extending from the humerus to the posterior third of the elytra, and the five elongated maculae of dark brown pubescence extending transversely from the base of the lateral band to almost the suture (united or separated laterally from each other). There are several species in Mexico and Central America that have a similar pubescent pattern on prothorax and elytra, such as Urgleptes cazieri , U. celtis , U. charillus (Bates, 1885) , U. clerulus (Bates, 1881) , U. dorotheae Gilmour, 1960 , U. euprepes , U. fasciatus (Bates, 1881) , and E. pareuprepes Gilmour, 1960. However, in all these species, between the end of the central third and the beginning of the posterior third, there is a continuous transverse band of dark brown pubescence, usually irregular and extending, obliquely or not, from the lateral margin to the suture or almost to the suture. In addition, all these species lack a well-defined continuous dark-brown lateral band from the humerus to almost the posterior third of the elytra. Of these species, U. martini sp. nov. is more similar to U. celtis . However, in addition to the differences in the pubescence pattern of the elytra mentioned above, U. celtis clearly has a narrower mesoventral process and the femora, especially meso- and metafemora, are more widened and slightly less pedunculate than in U. martini sp. nov. (See figures 12–15).

Remarks. The size of the specimens of the type series ranges from 4.0 to 6.4 mm in length and 1.3 to 2.1 mm in width. The pubescent pattern is constant, although the dark-brown pubescent maculae on the elytra may be lighter and smaller in some specimens. The integument of most of the body can vary from light brown to dark brown, as can be seen in the images of the abdomen of the female and male in figures 10 and 11.

Etymology. We dedicate this species to Martín Zurita, a young Mexican entomologist and great companion and friend of the first, third, and fourth authors, who unfortunately passed away recently. We honor his memory by doing what he loved so much.
