First record of the genus Gryonella Dodd from Brazil, with the description of a new species (Hymenoptera: Platygastridae).

ABSTRACT: A new species of Gryonella Dodd, 1914, is described and illustrated based on specimens from Brazil (Mato Grosso do Sul). Gryonella matogrossensis sp. nov. is similar to G. bruesi Dodd but can be distinguished mainly by its lighter color, rounded vertex, striated cheeks and large metanotal teeth. A key to the described species of Gryonella is provided. Taxonomic notes on the genus are included.
