The dispar  group

( Figs 1–4, 7–14View FIGURES 1–8View FIGURES 9–14, 22–27View FIGURES 22–27, 35–40View FIGURES 35–40, 48–53View FIGURES 48–53, 61–70, 78–83, 91–96, 97–102, 117–119)

Included species: A. crassipunctatus  , A. dispar  , A. insuturatus  , A. schwarzi  , A. taeniopygus  and Amblycerus goianiensis Santos & Ribeiro-Costa  , sp. n.

Diagnosis. The dispar  group is characterized by the following combination of characters: scutellum tridentate with median tooth longer than the lateral ones (Figs 61–70); elytra with uniform pattern of vestiture ( Figs 9–14View FIGURES 9–14); and pygidium with dense median strip of setae ( Figs 78–83View FIGURES 78–83). It can be separated from the spondiae  group mainly by the elytra with uniform pattern of vestiture (vertical stripes of setae, spondiae  group) and internal sac of male genitalia with different number and form of sclerites (two pairs and one unpaired sclerite with similar form, in the spondiae  group).
