Abstract
Two new species of the genus Quiva: Quiva buhrnheimi n. sp. and Quiva gutjahrae n. sp. from Brazilian Amazon are described. Determinations for distributional data previously published by Sovano & Mendes (2013) are clarified and the synonymy of Ituana dorisae under Q. abacata is confirmed. In this paper, an updated key to subgenus Quiva is provided.
