Key to Orizabus species of the United States of America

1. Clypeal carina usually entire, at most weakly emarginate in anterior view; protibia tridentate (when not worn) in both sexes with apex truncate to transversely rounded ( Fig. 5-7 View Figures 5-7 , 35 View Figures 32-35 ); male genitalia with paramera relatively thin, laterally dentate ( Fig. 20, 21 View Figures 20-25 , 33, 34 View Figures 32-35 ); body usually smaller (12 to 19 mm long), strongly convex, pyriform ........................................................... 2

— Clypeal carina usually obviously bidentate in anterior view (unless worn; Fig. 1, 2 View Figures 1-4 , 12, 13 View Figures 12-15 , 37 View Figures 37-38 ); female protibia tridentate, with apex oblique ( Fig. 10 View Figures 10-11 , 37, 38 View Figures 37-38 ); male with protibia blade-like, edentate ( Fig. 8, 9 View Figures 8-9 , 12 View Figures 12-15 , 36 View Figure 36 ); male genitalia and shape different; body normally longer than 19 mm ............................................................................................................................................ 3

2(1). Clypeal carina apparently apical, in dorsal view often weakly angulate with angle opening anteriorly ( Fig. 6 View Figures 5-7 , 32 View Figures 32-35 ); pronotum with posterior marginal bead more or less effaced and anterior marginal bead not angulately broadened at middle; antennal club as long as or shorter than distance between frontoclypeal tubercle and clypeal carina ( Fig. 6 View Figures 5-7 , 32 View Figures 32-35 ); paramera with lateral tooth just anterior to middle, tooth often appressed ( Fig. 33, 34 View Figures 32-35 ) ................... O. pyriformis (LeConte)

— Clypeal carina obviously subapical, in dorsal view straight ( Fig. 5 View Figures 5-7 ); pronotum with posterior marginal bead complete or only shortly interrupted at middle, anterior marginal bead with posterior edge angularly broadened at middle; antennal club obviously longer than distance between clypeal carina and frontal tubercle ( Fig. 5 View Figures 5-7 ); paramera with lateral tooth at about apical third ( Fig. 20, 21 View Figures 20-25 ) ............................................................................ O. mcclevei new species

3(1). Posterior edge of anterior pronotal bead usually not posteriorly prolonged at midline, in females bead often slightly narrowed at midline ( Fig. 10 View Figures 10-11 ); pronotal disc simply convex, without broad depression in anterior half ( Fig. 8 View Figures 8-9 ); male paramera with apex incised ( Fig. 30 View Figures 26-31 ); length usually less than 22 mm ............................................................................ O. pinalicus new species

— Posterior edge of anterior pronotal bead in male posteriorly prolonged at midline into triangular tubercle ( Fig. 1, 3 View Figures 1-4 , 36 View Figure 36 ), in female usually at least obtusely angulate (bead medially broader; Fig. 37, 38 View Figures 37-38 ); pronotal disc often with broad depression behind tubercle (lacking in most females); male paramera without apical incisure ( Fig. 26-29 View Figures 26-31 ); length usually more than 22 mm but smallest individuals of similar size .......................................................................................... 4

4(3). Clypeus parabolic, with lateral margins straight to weakly convex; clypeal carina obviously subapical, with teeth apices separated by about a dorsal eye width or more ( Fig. 1 View Figures 1-4 , 37 View Figures 37-38 ) .......... ............................................................................................................. O. clunalis (LeConte)

— Clypeus strongly narrowed, subtriangular, with lateral margins straight or weakly concave; clypeal carina apparently apical, with teeth narrowly separated (much less than a dorsal eye width) such that clypeal carina appears cleft ( Fig. 3 View Figures 1-4 , 38 View Figures 37-38 ) ......................... O. ligyroides Horn
