(2003) , which contains references to figures that are useful in interpreting the key but are not duplicated here. Accordingly, we encourage use of the key in conjunction with our earlier contribution ( Michener et al., 2003 ). The key below differs from the 2003 version primarily in that C . wileyi is included, as is the female of C . rozenorum . 1. Males.......................................................................................................... 2 – Females....................................................................................................... 5 2. Clypeus largely brownish yellow, densely punctate except near lower margin ( Guatemala , Mexico ) ..................................................... C . clypeata (Smith) – Clypeus brown or black, concolorous with remainder of head, at least lower half of clypeus with areas having punctures separated by about a puncture width or more of shiny integument.............................................................3 3. T2 and T3, and to some degree T4, covered with suberect black setae ( Guatemala ).................................................................................. C . wileyi sp. n. – T2 to T4 covered with pale brown setae...................................................... 4 4. Metatibia little over three times as long as wide, upper and lower margins both convex; legs brownish black ( Costa Rica , El Salvador , Guatemala )........ ..................................................... C . rozenorum Michener, Engel & Ayala – Metatibia nearly 4.5 times as long as wide, lower margin straight, upper margin convex; legs reddish brown, metabasitarsi yellowish dark testaceous ( Costa Rica )........................................... C . inbio Michener, Engel & Ayala 5. Clypeus densely punctate, with erect brown setae, some of them bent at tips, surface of clypeus nearly flat ( Guatemala , Mexico )......... C . clypeata (Smith) – Clypeus with lower two thirds medially shining, with scattered coarse punctures and other irregularities ( Figs. 2, 3 ), setae not erect, not bent at tips .... 6 6. Pile of mesoscutum and mesoscutellum black or nearly so ( Figs. 3 , 13); setae of posterior half of dorsal surface of T1 dusky or blackish, unlike white or ochraceous hairs of anterior half ( Guatemala ) ....................... C . wileyi sp. n. – Pile of mesoscutum and mesoscutellum ochraceous ( Figs. 1 , 2 ), tips of setae usually brown or blackish; setae of T1 uniformly whitish or orchraceous or dusky setae intermixed on posterior part..................................................... 7 7. Distance between posterior ocelli distinctly less than 1 OD ( Costa Rica )...... .............................................................. C . inbio Michener, Engel & Ayala – Distance between posterior ocelli subequal to 1 OD ( Costa Rica , El Salvador , Guatemala )................................... C . rozenorum Michener, Engel & Ayala
