Diagnosis. Total length 24.4–28.9 mm; head, pronotum and elytra metallic blue, violet or blue-green; legs and abdomen metallic blue or greenish blue; head rounded to rectangular, 1.22–1.50 times as long as wide, almost as wide as pronotum (0.86–1.11 times), dorsal and ventral surface convex, moderately convex or flat, ventral surface with slightly dense, expanded, umbilicate punctures (10–19 in each half of head), arranged in “v” (similar to Fig. 52); apical antennomere in males 1.40–1.74 times longer than wide, almost as long as antennomeres 9+10 combined (1.00–1.09 times); mandibles with basal external channel (Fig. 63); pronotum slightly longer than wide (1.16–1.41 times), shorter than elytra (0.72–0.78 time its length), with two clearly visible depressed areas in posterior third (Fig. 56); prosternum transverse (length/width: 0.65–0.75); aedeagus pear-shaped, big (5.56–6.75 mm), with parameres short (0.24–0.28 times as long as median lobe), apical area of median lobe 0.29–0.35 times as long as the total length of median lobe, and internal sac conspicuous (Fig. 79).
Variation. Great variation in color and body length. Generally the smaller specimens have a rounded head, less convex dorsally, and shorter mandibles.
Nomenclatural notes. The revision of the holotype specimen of P. pauloensis (Sharp, 1876), a previous synonym of P. fulgens (Fabricius, 1793), allowed us to recognize that the names P. amazonicus (Sharp, 1876), P. carinatus (Bernhauer, 1916), P. aureipennis (Bernhauer, 1927) and P. v i o l a c e u s (Olivier, 1795) refer to a single Amazonian species, P. f u l g e n s, which was previously confused even with Mexican specimens that actually belong to P. simplicicollis. Even Sharp (1867) was not completely sure that P. amazonicus and P. pauloensis, which were described in the same paper, were in fact two different species.
Geographical distribution. Colombia, Guyana, Venezuela, and Ecuador (first national records), Surinam, French Guiana, Brazil, Peru, and Bolivia (not Mexico; Herman 2001).
