Dimensions (mm) (holotype male/ paratype male/female paratypes). Total length, 4.20/3.60/4.00–4.05; prothoracic length, 0.75/0.65/0.70; anterior prothoracic width, 0.80/0.70/0.80–0.85; posterior prothoracic width, 0.90/0.75/0.90–0.95; maximum prothoracic width, 1.25/1.10/1.20–1.25; humeral width, 1.45/1.30/1.40–1.45; elytral length, 3.05/2.50/2.85–3.00.

Type specimens. Holotype male from ECUADOR, Imbabura: Cabañas Intag Colibri , 1900 m, Intag, 17-19 Jun 2023, J. Vlasak leg. ( MZSP, formerly JVCO). One paratype male and two paratype females, same data as holotype ( JVCO).

Etymology. The specific epithet “colibri ” is derived from the name of the place where the type series was collected —Cabañas Intag Colibri. It is a noun in apposition.

Remarks. Urgleptes colibri new species is similar to U. clerulus ( Bates, 1881) (see photographs on Bezark (2024a) and Bates (1881)) but differs as follows: distal antennomeres blackish; elytra shorter than four times prothoracic length; oblique dark integumental band on anterior third of dorsal surface of elytra reaching humerus; yellowish-white pubescent area on dorsal anterior half of elytra with one short, longitudinal brownish pubescent band; dorsal dark pubescent maculae near apex of elytra not reaching epipleural margin; and outer apex of elytra rounded. In U. clerulus , the distal antennomeres are mostly brownish, elytra slightly longer than four times the prothoracic length, oblique dark integumental band on the anterior third of the dorsal surface of elytra not reaching the humerus, yellowish-white pubescent area on the dorsal anterior half of elytra with two short, longitudinal brownish pubescent bands, dorsal dark pubescent area near apex of elytra reaching epipleural margin, and the outer apex of elytra is dentate. The new species is also similar to U. vulcanensis Santos-Silva, Pérez-Flores, Bezark and Monné, 2024 , but differs by the slender body (stouter in U. vulcanensis ), upper eye lobes with six rows of ommatidia (four in U. vulcanensis ), and the largest brown macula on posterior half of elytra oblique (transverse in U. vulcanensis ).
