Key to species of Central American Caupolicana

The key to species of Central American Caupolicana , below, is based on that of Michener et al. (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
