Key to species-groups of Protopolybia Ducke  

1. Species with posterior aspect of propodeum gently convex around a narrow median groove or with posterior face projecting symmetrically to either side of median groove, forming two moderately high protuberances ( Fig. 23 View FIGURES 23–40 )..................................................................................................... P. exigua   species-group.

– Species with posterior aspect of propodeum with a wide and shallow cavity ( Fig. 24 and 25 View FIGURES 23–40 )...........................2

2. Occipital carina strong and salient throughout ( Fig. 26 and 27 View FIGURES 23–40 ) and pronotal pretegular carina, posteriorly adjacent area strongly developed, adjacent area wider and T 1 in dorsal view with petiole very short; distal margin wider and nearly straight, cup-like ( Fig. 30 and 31 View FIGURES 23–40 )........................................................... P. picteti-emortualis   species-group.

– Occipital carina fading at some point near the middle of gena height or fading very close to the insertion of the mandible ( Fig. 28 and 29 View FIGURES 23–40 ); T 1 in dorsal view with petiole and distal margin variable ( Fig. 32 and 33 View FIGURES 23–40 )............................... 3

3. Large and robust species, with length of fore wing between ca. 5.1–5.7mm. T2 with shape of tergum wider than long, profile strongly bulging antero-laterally, spiracles tending to face forward ( Fig. 34 and 35 View FIGURES 23–40 ). Color black with yellow marks ( Fig. 1-10 View FIGURES 1–6 View FIGURES 7–10 )............................................................................ P. chartergoides   species-group.

– Small and slender species, with length of fore wing between ca. 4.75–5.1mm. T2 with shape of tergum wider than long, anterior contour distinctly convex in both dorsal and lateral view ( Fig. 36 and 37 View FIGURES 23–40 ), spiracles not tending to face foreward. Color variable, brown or entirely yellow with few black marks........................................... P. sedula   species-group.
