Diagnosis.

Amblycerus sclerolobii differs from the others of the group by the armature of the internal sac of male genitalia. The AR has one pair of sclerites (Fig. 6 H View Figure 6 ) ( A. truncatus Ribeiro-Costa , sp. nov., A. falcorostrus Ribeiro-Costa & Morse , sp. nov., A. biacutus Ribeiro-Costa , sp. nov., A. morsei Ribeiro-Costa , sp. nov. has one sclerite- Figs 2 View Figure 2 , 3 F View Figure 3 , 4 F View Figure 4 , 5 G View Figure 5 ; A. manauara has two pairs- Fig. 9 F View Figure 9 ), but A. marinonii , A. kingsolveri and A. tachigaliae share with A. sclerolobii one pair (Figs 7 G View Figure 7 , 8 F View Figure 8 , 10 G View Figure 10 ). Although A. sclerolobii can be easily separated from these last three species by the serrate winding laminar sclerites at MR (Fig. 6 H View Figure 6 ) ( A. kingsolveri , A. marinonii , A. tachigaliae have straight laminar sclerites: Figs 7 G View Figure 7 , 8 F View Figure 8 , 10 G View Figure 10 ).

Note.

Ribeiro-Costa (2000) described this species as having the general integument color contrasting with the antennae, thoracic ventrites, and legs. Here we present illustrations of the extremes of this contrast (Fig. 6 C, D View Figure 6 ).

Distribution.

Brazil (Amazonas-Estirão do Equador, Minas Gerais-Viçosa).
