Description
. The
Cyclocephala fasciolata
species group consists of four species and is characterized by following combination of characters. Color black except pronotum with 2 transverse, slightly oblique, reddish-orange bands; body broad, subrectangular (
Fig. 2A–D
) (

Bates
is totally black (
Fig. 6E
).
Head:
Frons mostly impunctate, frontoclypeal suture slightly indicated (
Fig. 2A–D
). Clypeus with punctures dense to sparse, clypeal apex parabolic, slightly reflexed (
Fig. 2A–D
). Mandible without teeth, inner apex slight concave (
Fig. 9A, C
); labium densely setose, apex widely notched, paraglossa slightly developed (
Fig. 12C–D
); maxilla with galea developed, with 6 teeth, lacinia not developed, apex with slender, long setae (
Fig. 9B, D
). Epipharynx rectangular, densely setose, apex projecting at center (ventral view,
Figs. 13E–F
;
14A–B
). Antenna with 10 antennomeres, club subequal in length to antennomeres 2–7 (slightly shorter in female)
Pronotum:
Surface with punctures moderate in density, moderately large to large (especially on sides). Base with marginal bead (Fig. 32A).
Elytra:
Surface with punctacte rows, punctures of striae and intervals similar to those of pronotum; entire surface often coarsely and transversely wrinkled obscuring rows of punctures. Wing vein AA
3
equal length to AA
4
(
Fig. 22A–D
). Anterior edge of wing distal of apical hinge glabrous (
Fig. 22D
).
Pygidium:
Surface usually moderately densely punctate; punctures moderate in size to more usually moderately large, ocellate, setigerous; setae short, tawny, moderately dense (
Fig. 24D–E
). In lateral view, surface in males evenly convex, weakly convex to nearly flat in females.
Legs:
Protibia bidentate in males, basal tooth slightly removed from others (
Fig. 18D, F–G
). Protarsus in male enlarged, tarsomeres 2–4 successively gradually larger, fourth with small tooth on ventral surface, fifth large, curved, with small angulation at base on ventral side (
Figs. 17C–E
), all tarsomeres longitudinally striate on dorsal face, median claw large, curved, apex cleft (
Fig. 15C–E
); external edge with some striations (
Fig. 16C–E
). Metatarsus subequal in length to metatibia. Females with protibia tridentate (
Fig. 18E
).
Venter:
Prosternal process moderately long, columnar, apex obliquely flattened in a transverse oval with anterior 2/3 to 4/5 raised into convex “button”.
Parameres:
As in
Fig. 27A–F
. Female similar to male, but protarsus simple. Gonocoxite and gonosternite fused (Fig. 32F).
