Abstract

Abstract Two new species of Asphondylia inducing galls on Asteraceae are described, A. gaucha from the state of Rio Grande do Sul and A. mineira from the state of Minas Gerais. Their host plants are Vernonanthura discolor (Sprengel) H. Rob., and V. polyanthes (Sprengel) Vega & Dematteis, respectively, both native to Brazil. Illustrations of relevant morphological characters are provided. The new species are compared with congeneric Neotropical species. The types are deposited in the Entomological Collection of the Museu Nacional/Universidade Federal do Rio de Janeiro.
