Diagnosis. Cyclocephala brevipennis can be distinguished by the glabrous frons and clypeus ( Fig. 25C View FIGURE 25 ) (similar to C. fasciolata , Fig. 2C View FIGURE 2 , but with setae present in C. santandereana Fig. 25D View FIGURE 25 ); pygidium black (similar to C. fasciolata ), with punctures stronger, denser and with slender, long setae ( Fig. 24D View FIGURE 24 ), while the pygidium of C. santandereana is testaceous, with sparse punctures, and with slender, long setae ( Fig. 24E View FIGURE 24 ). The surface of the pronotum, elytra, and metasternum has sparse punctures (dense in C. fasciolata dense); the surface of the pygidium is finely scabrous with ocellate punctures (in C. fasciolata the surface is rugopunctate, and the punctures are not ocellate). The external edge at the base of protarsomere 5 lacks a small concavity ( Fig. 17C View FIGURE 17 ) (with a small concavity in C. santandereana ).

Redescription. Male ( Fig. 2A View FIGURE 2 ). Length 19.4–20.0 mm; width 8.9–10.1 mm. Color black except each elytron and pronotum with transverse, slightly oblique, orange band not reaching lateral or sutural margins; band occasionally broken in 4 spots or nearly obsolete. Some specimens have elytra almost completely reddish orange. Head: Surface of frons and clypeus glabrous, with punctures moderate in size, becoming denser and smaller at clypeal apex. Clypeal apex broadly, weakly rounded, narrowly reflexed. Mandibles apically rounded, internal face with a groove ( Fig. 9A View FIGURE 9 ); labium densely setose, paraglossa undeveloped, apex widely notched ( Fig. 12D View FIGURE 12 ); maxilla with galea developed, with 6 teeth ( Fig. 9B View FIGURE 9 ). Epipharynx rectangular, densely setose, apex projecting at center ( Fig. 13E–F View FIGURE 13 ). Interocular width equals 3.6–3.8 tranverse eye diameters. Antenna with 10 antennomeres, club subequal in length to antennomeres 2–7 (slightly shorter in female). Pronotum: Surface similar in punctation to frons by except punctures slightly larger. Base with strong marginal bead (Fig. 32B). Elytra: Surface with rows of moderately large, shallow punctures. Pygidium: Surface finely scabrous, dull, setigerous; setae moderately dense, long, tawny in color ( Fig. 24D View FIGURE 24 ). In lateral view, surface regularly convex. Legs: Protibia bidentate ( Fig. 18D View FIGURE 18 ). Protarsus enlarged, tarsomeres 2–4 with large ventral lobes, all tarsomeres longitudinally striate on dorsal face, 5 th large ( Fig. 17C View FIGURE 17 ), median claw moderately curved, without lobes or tooth, but lateral internal surface with longitudinal lines ( Fig. 16C View FIGURE 16 ), apex finely cleft ( Fig. 15C View FIGURE 15 ). Metatarsus longer than metatibia. Venter: Prosternal process long, stout, apex obliquely flattened into a transverse oval with anterior 2/3 raised as convex “button”. Genitalia: Parameres as in Fig. 27C–D View FIGURE 27 .

Female ( Fig. 2B View FIGURE 2 ). Length 18.9–19.8 mm; width 7.3–8.1 mm. Similar to male, but surface of frons and clypeus with punctation denser. Antennal club slightly shorther than antennomeres 2–7. Pronotum and elytra with punctures stronger and denser. Abdominal ventrite VIII entire. Epipleuron (ventral view) expanded into elongate, laterally expanded flange extending from middle of lateral edge of metacoxa to anterior edge of third sternite; in lateral view, epipleuron beneath flange produced ventrally into strong, posteriorly projecting, acute tooth ( Fig. 20D View FIGURE 20 ). Pygidial surface shiny, punctures moderately dense and moderate in size, setigerous. In lateral view, surface nearly flat. Protibia tridentate ( Fig. 18E View FIGURE 18 ). Protarsus simple. Length of metatarsus shorter than metatibia. Gonocoxite and gonocoxal sternite fused (Fig. 32F).

Distribution. Cyclocephala brevipennis is known from Ecuador ( Endrödi 1985; Ratcliffe et al. 2020) and Colombia ( Neita 2011). The species was previously reported in Colombia but was misidentified as C. fasciolata by Neita (2011).

Life history. Adults are active during the night and attracted to lights.
