Fannia Robineau-Desvoidy, 1830 is known from 68 Neotropical species, two of them occuring in the Amazon State (Brazil). The analysis of a material recently collected in Pico Tamacuari, Amazonas, led to the description of F. caramaschi sp. nov., herein described with illustrations from male and female. F. obscurinervis Stein, 1900 is recorded for this State for the first time. A key to the identification of the four Fannia species recorded to Amazon is also presented.
