Amblycerus marinonii can be distinguished mainly by the presence in the internal sac of male genitalia at AR of one pair of tooth-shaped, large and strongly curved sclerite (Fig. 8 F). Although A. marinonii shares one pair of sclerite with A. sclerolobii (Fig. 6 H), A. tachigaliae (Fig. 10 G), A. marinonii (Fig. 8 F) and A. kingsolveri (Fig. 7 G) it can be separated by the conspicuous form of the AR sclerites. Distribution. Brazil (Mato Grosso-Cuiabá, Goiás-Dianópolis, Barro Alto *). Host plants. Fabaceae: Tachigali rubiginosa (Mart. ex Tul.) Oliveira-Filho (quoted as Sclerolobium paniculatum var. rubiginosum).
