Dorsum green or greenish-blue but never mostly dark blue. Central Brazil , Bolivia . ................................... ......................................................................................... A. desmaresti ( Boheman, 1850 ) – The reticulation is lower, broader and denser thus enclosing smaller fields. Surface of field irregular and moderately but distinctly punctate. Dorsum blue or with slight greenish tint. Costal south Brazil , Argentina , Paraguay , Uruguay . ................................................... ........................................................................................... A. parellina ( Boheman, 1850 ) 3 Disc of elytra moderately convex, in lateral view highest approximately in the middle. Apical third of elytra without elevated reticulation, only traces are visible as punctate lines. ................................................................................................................................ 4 – Disc of elytra strongly convex, in lateral view highest in postscutellar point. Apical third of elytra with low but distinctly elevated reticulation. .................................................... 5 4 Dorsum bright metallic green, blue or turquoise. Pronotum widest around midlength and regularly converging to both sides. Upper Amazon Basin. ... A. connectens ( Baly, 1869 ) – Dorsum black with bronze tint. Pronotum widest in anterior third thus it looks more constricted basally than apically. Lowland Peru . ................. A. stragulata ( Boheman, 1862 ) 5 Reticulation on elytral disc high, strongly shiny and enclosing smaller velvet-like inside fields, which are nearly impunctate and thus the beetle looks generally shinier. ............ 6 – Reticulation on elytral disc low, moderately shiny and enclosing larger velvet-like inside fields, which are finely but distinctly punctate and thus the beetle looks more opaque. .... 7 6 Reticulation on disc of elytra wide and densely punctate. Lower Amazon (Guyanas, Amapá , Pará , etc.). ........................................................ A. caedemadens ( Lichtenstein, 1796 ) – Reticulation on disc of elytra narrow and impunctate. Bolivia ........................................... ................................................................................................... A. boliviana Spaeth, 1916 7 Dorsum dark olive green or black, sometimes with slightly indicated red reticulation on explanate margin. Northern part of Andes to N Peru . ..................................................... 8 – Dorsum bright metallic green, explanate margin always with red reticulation. Southern part of Andes from Peru to Argentina and adjacent lowlands towards the Amazon Basin. ................................................................................................. A. peruviana Spaeth, 1915 8 Elytra uniformly black or olive green. ............................. A. lacertosa ( Boheman, 1862 ) – Explanate margin of elytra with more or less indicated red reticulation. ........................... .............................................................................................. A. calvata ( Boheman, 1862 )
