description: Cyclocephala santandereana Neita, new species   
(Figs. 2D; 15E; 16E; 17E; 18G; 24E; 25D; 27E–F; 39)  
 Type material. Holotype and paratype labeled “ Colombia, Santander, San Vicente / de Chucurí, Finca Familia Rincón, / 6º50´57.3´´N; 73º23´37.0´´W. WGS84 / 1214 m, Manual en Árbol de Cacao (Theobroma cacao L.) / 29.iii.2018, D.F. Silva Tavera. IAvH-E-198644.” Holotype deposited at IAVH; paratype deposited at UNSM.   
 Etymology. The species name “ santandereana ” refers to the type locality in Santander Province, Colombia and should be treated as an adjective in the nominative singular.   
 Diagnosis. Cyclocephala santandereana can be distinguished by the setose frons and clypeus (Fig. 25D) (glabrous in C. brevipennis and C. fasciolata (Fig. 25C)); pygidium testaceous, with sparse punctures and slender, long setae (Fig. 24E) (pygidium black in C. brevipennis and C. fasciolata (Fig. 24D)). The external edge at the base of protarsomere 5 with a small concavity (Fig. 17E), lacking a small concavity in C. brevipennis and C. fasciolata (Fig. 17C–D).   
 Description. Male holotype (Fig. 2D). Length 21.4 mm; width 10.0 mm. Color black except each elytron and pronotum with transverse, slightly oblique band of reddish orange, band not reaching lateral or sutural margins; pygidium testaceous. Head: Frons and clypeus setose laterally (Fig. 25D), with punctures moderate in size, becoming denser and smaller at clypeal apex. Clypeal apex broadly, weakly rounded, narrowly reflexed. Mandibles with concave inner edge, apex without teeth (as Fig. 9C); labium densely setose, paraglossa undeveloped, apex widely notched (Fig. 12D); maxilla with galea developed, with 6 teeth (as Fig. 9D). Epipharynx, rectangular, densely setose, apex projecting at middle (Fig. 14A–B). Antennal club subequal in length to antennomeres 2–7. Pronotum: Surface punctation similar to frons except punctures slightly larger. Base with strong marginal bead (Fig. 32A). Elytra: Surface with rows of moderately large, shallow punctures. Pygidium: Surface finely scabrous, dull, setigerous; setae moderately dense, long, tawny. In lateral view, surface regularly convex (Fig. 24E). Legs: Protibia bidentate (18G). Protarsus enlarged (Fig. 2D), tarsomeres 2–4 with large ventral lobes, all tarsomeres longitudinally striate on dorsal face, tarsomere 5 large, moderately curved (Fig. 17E), without lobes or tooth, but lateral internal surface with longitudinal lines (Fig. 16E), median claw large, strongly curved, apex finely cleft (Fig. 15E), external edge with basal lines (Fig. 17E). Length of 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. 27E–F.   
 Female. Unknown.   
 Paratype. Length 19.9 mm; width 9.9 mm. Similar to holotype except for the elytron and pronotum with transverse, slightly oblique band of reddish orange, band not reaching lateral or sutural margins, band occasionally broken in 4 spots or nearly obsolete   
 Distribution. Cyclocephala santandereana is known only from the type locality.   
 Life history. Adults are active during the day. The adults were taken on the leaf of Theobroma cacao L. (Malvaceae). The life history of this species is unknown.
