Diagnosis. Cyclocephala kaszabi is easily recognized from the other species in the C. ligyrina species group by the furrowed, punctate rows on the elytra (punctate rows of elytra not in furrows in the other species). The female epipleuron is abruptly expanded into a lobe extending from the middle of the metasternum to the level of the third sternite, but in other species (Fig. 20E), the females do not have the epipleuron abruptly expanded into a lobe.

Redescription. Male (Fig. 3B). Length 18.6–23.0 mm; width 9.4–11.0 mm. Color black. Head: Frons moderately to densely punctate, punctures moderate to moderately large. Clypeus sparsely punctate, punctures small (rarely moderate in size); apex broadly truncate, narrowly reflexed (often weakly emarginate), apical angles rounded; labium densely setose, paraglossa undeveloped, apex widely notched; maxilla with galea developed, with 6 teeth. Interocular width equals 4.0–4.2 transverse eye diameters. Antenna with 10 antennomeres, club subequal in length to antennomeres 2–7. Pronotum: Surface with moderate to moderately large, moderately dense punctures. Base without marginal bead. Elytra: Surface of disc with distinct rows of moderate to mostly large, umbilicate punctures in furrows. Pygidium: Surface with moderate to large punctures; punctures sparsely to densely punctate, setigerous; setae minute, tawny. In lateral view, surface regularly convex. Legs: Protibia tridentate, basal tooth very small (Fig. 18I). Basal tooth with arcuate sides and a distinct notch on posterior margin (Fig. 16G). Protarsus enlarged, tarsomeres 2–4 successively gradually larger; fifth large, only weakly curved, with large tooth at base; median claw large, strongly curved (Fig. 16G), broadly split into a wide ramus and a slender ramus (Fig. 15G); metatibia on external face with 2 rows of setae, the 2nd row crosses the external face of metatibia (Fig. 19E). Venter: Prosternal process long, stout, apex obliquely flattened into a wide, transversely oval disc with anterior 4/5 raised as a convex “button”. Genitalia: Parameres as in Fig. 29A–B.

Female (Fig. 3C). Length 18.5 mm; width 9.25 mm. Similar to male, but pronotal disc smooth. Abdominal ventrite VIII entire at apex. Epipleuron (ventral view) enlarged into elongate lobe extending from about middle of metasternum to middle of third abdominal sternite; in lateral view, ventral margin of expanded portion convex and without tooth (Fig. 20E). Pygidial surface shiny, with punctures moderate in density and size, setigerous; setae short, tawny, often abraded away. In lateral view, surface nearly flat. Protibia tridentate. Protarsus simple, metatarsus shorter than metatibia. Gonocoxite smaller than gonocoxal sternite, lacking a membranous area (Fig. 32G).

Distribution. Cyclocephala kaszabi is known from Guatemala, Honduras, Nicaragua, Costa Rica, Panama, Colombia, and Ecuador (Endrödi 1966, 1985; Ratcliffe 2003; García-Robledo et al. 2004, 2005; Ratcliffe & Cave 2006; Ratcliffe et al. 2013, 2020).

Life history. Adults are attracted to lights. A few specimens have been taken from Xanthosoma daguense Engl. (Araceae) and Dieffenbachia longispatha Engl & K. Krause (Araceae) (Young 1986; García-Robledo et al. 2004, 2005). The elevational range for C. kaszabi is from near sea level to 1,200 m.
