Abstract
Four new Brazilian species of the genus Amorphicola, previously known only from North America, are diagnosed, named, keyed and illustrated: A. ascigera sp. nov. from the states of Mato Grosso and Minas Gerais, developing on Dalbergia villosa (Fabaceae), A. dalbergiae sp. nov. from Paraná, Rio Grande do Sul, Rio de Janeiro and São Paulo, developing on Dalbergia frutescens; A. isabellae sp. nov. from Mato Grosso do Sul and Paraná, as well as A. marsaroi sp. nov. from Rio Grande do Sul. Immatures and host plants are known for the first two but not for the last two species. Based on the occurrence of the genus in Brazil, and its sister group relationship with the Taiwanese genus Danieliana, it is concluded that Amorphicola is a tropical faunal element rather than a Nearctic endemic. The two previously known species develop on Amorpha (Fabaceae), a genus closely related to Dalbergia.
