Type material. Holotype, allotype, and paratypes labeled “ Colombia, Magdalena, Santa / Marta, Correg. Minca, Hda. Bellavista, Bosque Intervenido , / Bosque Subandino , 11º5´42´´N; 74º / 4´42.8´´W. WGS84, 1547 m, Trampa / de Luz Negra, Manual, 1.vi.2019, / Jhon César Neita Moreno.” Holotype [♂ IAvH-E-216406] and allotype [♀ IAvH-E-216407] are deposited at IAVH. Fifteen paratypes with the following data: 3 males and 12 females with same data as holotype. [2 ♂ IAvH-E-216404, IAvH-E-216405; 7♀ IAvH-E-216408, IAvH-E-216409, IAvH-E- 216410, IAvH-E-216411, IAvH-E-216412, IAvH-E-216413, IAvH-E-216415] are deposited at IAVH. Two paratypes (female and male) are deposited at ( UNSM). Other paratypes (females) are deposited in CTNI (1), ICN ‒MHN (1), MEFLG (1), and UNAB (1) .

Etymology. This species is named in honor of the Arhuaco Indigenous Community that inhabits this area of the country, and who are considered the guardians of important Neotropical biodiversity. This name should be treated as a noun in apposition.
Diagnosis. In C. rufa and C. arhuacana , the surface on the pygidium has sparse punctures ( Fig. 25A–B View FIGURE 25 ), but in C. dalensi , C. kaszabi , and C. ligyrina , the surface of the pygidium has dense punctures ( Fig. 24F–H View FIGURE 24 ). Cyclocephala arhuacana has small and shallow pygidial punctures ( Fig. 25D View FIGURE 25 ), whereas the punctures are larger and deeper in C. rufa ( Fig. 25A View FIGURE 25 ). The parameres ( Fig. 30A–B View FIGURE 30 ) are also different from those of C. rufa ( Fig. 29E–F View FIGURE 29 ).
Description. Holotype male ( Fig. 4C View FIGURE 4 ). Length 24.5 mm; width 11.1 mm. Color black. Head: Surface of frons and clypeus with punctures moderately dense, moderately large except those on occiput and apex of clypeus that are smaller and slightly denser. Clypeus with anterior angles broadly rounded, apex broadly truncate and weakly emarginate. Mandibles apically rounded, internal face with a groove ( Fig. 10C–D View FIGURE 10 ); labium densely setose, paraglossa undeveloped, apex slightly notched ( Fig. 12F View FIGURE 12 ); maxilla with galea developed, with 6 teeth ( Fig. 11C–D View FIGURE 11 ). Epipharynx with apex parabolic, densely setose, with central line of setae (ventral view, Fig. 14E View FIGURE 14 ), dorsal surface lacking setae, but apex and edge with setae (dorsal view, Fig. 14F View FIGURE 14 ). Interocular width equals 3.0–3.3 transverse eye diameters. Antenna with 10 antennomeres, club subequal in length to antennomeres 2–7. Pronotum: Surface with punctures as on frons. Base lacking marginal bead. Elytra: Surface with distinct rows of punctures, punctures (and those on intervals) ocellate, moderately large, moderately dense. Pygidium: Surface with sparse, small punctures, most with a minute, tawny seta. In lateral view, surface regularly convex ( Fig. 25B View FIGURE 25 ). Legs: Protibia tridentate, basal tooth small, directed “forward”, and slightly removed from others ( Fig. 18L View FIGURE 18 ). Protarsus enlarged, tarsomeres 2–4 successively gradually larger, tarsomere 5 large, only weakly curved ( Fig. 17J View FIGURE 17 ), with large basal tooth; median claw large, strongly curved ( Fig. 16J View FIGURE 16 ), broadly split into a wide ramus and a slender ramus ( Fig. 15J View FIGURE 15 ); metatibia on external face with 2 rows of setae, second row crosses external face of metatibia ( Fig. 19H View FIGURE 19 ). Venter: Prosternal process long, stout, apex obliquely flattened into a wide, transverse oval with anterior 4/5 raised as convex “button”. Genitalia: Parameres as in Fig. 30A–B View FIGURE 30 . Internal sac as in Fig. 31D View FIGURE 31 .
Allotype female ( Fig. 4D View FIGURE 4 ). Length 23.6 mm; width 11.9 mm. Similar to male, but surface of frons and clypeus with denser punctures. Pronotum and elytra with punctures coarser and denser. Elytra with punctate rows weakly furrowed. Abdominal ventrite VIII entire. Epipleuron (ventral view) gradually tapering and then abruptly so at third sternite; in dorsal view, epipleuron gradually expands to level of third sternite; tooth on ventral surface of epipleuron absent in lateral view ( Fig. 20G View FIGURE 20 ). Pygidium: In lateral view, surface weakly convex to nearly flat. Legs: Protibia tridentate ( Fig. 18M View FIGURE 18 ). Protarsus simple. Length of metatarsus shorter than metatibia. Gonocoxite larger than gonocoxal sternite, gonocoxite without a membranous area ( Fig. 30C View FIGURE 30 ).
Variation. Males (3 paratypes). Length 22.9–23.8 mm; width 10.4–10.6 mm. Similar to holotype. Female (12 paratypes). Length 20.6–24.6 mm; width 10.2–11.9 mm. Similar to allotype.
Distribution. Cyclocephala arhuacana is known only in the Sierra Nevada at elevations above 1,400 m.
Life history. Adults they are active during the night and attracted to lights.
