1. Males ........................................................................................................................... 2

—. Females ........................................................................................................................ 5

2(1). Metasoma almost entirely yellow, frequently with brownish apical margins to segments, and propodeum entirely yellow ( Figs. 36, 37 ) ( Panama, Costa Rica) ..................................................................................... C. chibchani Engel , n. sp.

—. Metasoma largely dark brown to light brown ( Figs. 3, 4 , 20 , 27, 28 ), or, if as above, then propodeum brown with metallic green highlights ( Figs. 13, 15 ) .... 3

3(2). Mesepisternum largely or entirely dark brown with strong metallic green highlights ( Fig. 3 , 13 ); apical process of sternum VII more broad and blunt along apex ( Figs. 6 , 16 ) .......................................................................................................... 4

—. Mesepisternum entirely yellow to amber colored ( Fig. 20 ) [sometimes yellowish or reddish brown in older, faded specimens ( Fig. 27 )]; apical process of sternum VII more acute, triangular ( Fig. 23 ) (Amazon Basin, Guiana Shield) ..................... ........................................................................................................ C. minutum (Friese)

4(3). Metasomal terga largely yellow with brownish apical margins ( Figs. 13, 15 ); terminalia as in figures 16–19 [note the broader and more pronounced process of the sterna; more rounded cephalad-inner angle of the ventral gonostylar process, straighter inner margin of the volsella, &c.] ( Ecuador) .... C. tupaqi Engel , n. sp.

—. Metasomal terga entirely brown to dark brown ( Figs. 1 , 3, 4 ), sometimes with yellow anteriorly on first metasomal tergum; terminalia as in figures 6–9 [note the less pronounced process of the sterna; more acutely angled cephalad-inner angle of the ventral gonostylar process, deeply concave inner margin of the volsella, &c.] ( Bolivia) ........................................................... C. bulivyense Engel , n. sp.

5(1). Mesoscutellum, metanotum, and propodeum not entirely metallic green in color, entirely or mostly amber to yellow in color, sometimes with medial areas of metallic green on mesoscutellum and metanotum ( Figs. 31 , 34 , 44 ) ................. 6

—. Mesoscutellum, metanotum, and propodeum entirely metallic green in color, concolorous with mesoscutum ( Figs. 2 , 11 ) ( Bolivia) .... C. bulivyense Engel , n. sp.
