Key to species of Agenysa View in CoL
1 Whole explanate margin of elytra covered with elevated reticulation. ........................... 2
– Explanate margin of elytra with elevated reticulation only around its midlength or completely smooth. ................................................................................................................ 3
2 The reticulation is higher and narrower, strongly shiny and is enclosing relatively large fields that are velvet-like, smooth and only finely punctate on sides. Dorsum green or greenish-blue but never mostly dark blue. Central Brazil, Bolivia. ................................... ......................................................................................... A. desmaresti ( Boheman, 1850) View in CoL
– 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) View in CoL
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) View in CoL
– 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 View in CoL
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 View in CoL
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)
