Spermophagus bicolor Pic, 1927: 187 (original description, distribution).

Amblycerus bicolor : Ribeiro-Costa 1992: 167–168; 172 (redescription, type material, male genitalia); Ribeiro-Costa et al. 2018: 502–503 (catalog); Romero-Nápoles et al. 2021: 207 (catalog).

Type material.

This species was redescribed by Ribeiro-Costa (1992). The single syntype deposited in MNHN (Muséum national d’Histoire naturelle, Paris, France), a female, was examined, with the label • “ Itaituba , Amazones ”; however, we emphasize here that the locality “ Itaituba ” is in the Para state of Brazil .

Diagnosis.

Amblycerus bicolor can be distinguished by the species of the sclerolobii group and the other Amblycerus species by the scutellum with subacute apex (Fig. 11 C View Figure 11 ), pronotum with elongate coarse punctures on lateral areas (Fig. 11 B View Figure 11 ), prosternal process very narrow, laminar; elytra and pygidium with coarse punctures at apex and the color pattern of integument on the pygidium with two darker oval areas (Fig. 11 F View Figure 11 ). It is worth noting that in the male genitalia the two unpaired sclerites at MR differ, one anterior with denticles and the posterior is long, entire, not wishbone-shaped with separate stems (Fig. 11 G View Figure 11 ).

Distribution.

Brazil ( Para), Suriname, French Guiana.

Host plants.
