Key to the Neotropical Genera of Anoplognathini

1 Elytral margin with clear, membranous border (best seen at apex of elytra). Central Chile and Argentina to Tierra del Fuego ( Brachysternina ) ---------- 2

1' Elytral margin without clear membranous border. Central México to northern Argentina ----------------------------------------------------------------------------------------------------------------- 4

2 Unguitractor plate with 3 or more setae. Elytron bearing white, scale­like setae (sometimes absent due to abrasion). Claws simple. Tarsomere 5 with ventromedial tooth (similar to Fig. 7 ) ------------------------------ Hylamorpha Arrow

2' Unguitractor plate with 2 setae. Elytron glabrous or bearing white to orange, hair­like, slender, or thick setae. Claws split, toothed, or simple (if simple, then tarsomere 5 without a tooth). Tarsomere 5 with or without ventromedial tooth ------------------------------------------------------------------------------------------------------- 3

3 Dorsal color green. Pygidium and abdominal sternites with obvious thick, white setae (especially laterally at base) when viewed without magnification. Apex of female terminal abdominal sternite moderately to deeply emarginate. Male paramere with ventral and lateral sclerites ----------------------- -------------------------------------------------------------------------------------------------- Brachysternus Guérin­Méneville

3' Dorsal color brown to olive green. Pygidium and abdominal sternites usu­
