Key to species of the mandibularis View in CoL species group

NOTE: Males remain unknown for E. perfulgens , while females are as of yet undiscovered for E. bigibba .

1. Male: antenna with 11 flagellar articles; metasoma with seven exposed terga; metatibia inflated bearing organ slit (setose-lined opening) ............................. 2

—. Female: antenna with 10 flagellar articles; metasoma with six exposed terga; metatibia with well-developed and expanded corbicula ................................... 3

2(1). Malar area twice as long as diameter of mid-flagellar articles ( Fig. 135 View Figures 135–138 ); punctures on second metasomal tergum large (maximum length nearly 0.50x mid-ocellus diameter), longitudinally elongate, similar to punctures on third to seventh terga; malar area and mandibles predominantly ivory colored ( Figs. 134–135 View Figures 133–134 View Figures 135–138 ); large green bees with some blue highlights and moderate golden-bronzy iridescence [western areas of Amazon Basin ( Peru and Brazil)] ................................................................................ E. (E.) bigibba Dressler View in CoL

—. Malar area roughly 1.25 times as long as diameter of mid-flagellar articles ( Fig. 121 View Figures 121–126 ); punctures on second metasomal tergum small (puncture diameter about 0.20x mid-ocellus diameter), round, similar to punctures on third and anterior half of fourth terga (although these progressively larger), longitudinally elongate punctures appearing on posterolateral areas of third tergum and remaining terga ( Figs. 117–118 View Figures 117–118 ); malar area with variable amounts of ivory coloration but with noticeable brown coloration, mandible predominantly brown; large blue-purple bees with some green coloration on face ( Figs. 117–118 View Figures 117–118 ) [southeastern Brazil, northeastern Argentina, and southern Paraguay] ........................................................................... E. (E.) mandibularis Friese View in CoL

3(1). Malar area twice as long as diameter of mid-flagellar articles ( Fig. 141 View Figures 141–143 ); mesoscutellar tuft large, slightly wider than long, composed of yellow-fulvous setae; malar area and mandibles predominantly ivory colored ( Figs. 140–141 View Figures 139–140 View Figures 141–143 ); large bees with underlying integumental coloration green, strongly introgressed by red-coppery color in most parts of body and becoming dominant on metasoma (darker specimens, such as the holotype, have a rather red-bluish metasoma) ( Figs. 139–140 View Figures 139–140 ) [western areas of Amazon Basin] ......... E. (E.) perfulgens Moure View in CoL

—. Malar area roughly 1.25 times as long as diameter of mid-flagellar articles ( Fig. 122 View Figures 121–126 ); mesoscutellar tuft noticeably longer than wide, composed of black setae ( Fig. 119 View Figures 119–120 ); malar area with brown basal coloration and metallic highlights concolorous with other areas of face ( Fig. 122 View Figures 121–126 ); mandible predominantly brown; large blue-purple bees with some green coloration on face ( Figs. 119–120 View Figures 119–120 , 122 View Figures 121–126 ) [southwestern Brazil, northwestern Argentina, and southern Paraguay] ...........................................................................
