Abstract. The genus Difundella is redescribed. Seven species are recognized as be-
longing to the genus: D. cancerella n. sp., D. corynophora Dyar, D. diimiella Neunzig
and Dow, D. parana n. sp., D. subsutella (Schaus), D. teresina n. sp., and D. unguifera
n. sp. A key to species based on male adults is included. Difundella is compared to the
similar genera Nefundella Neunzig, Coptarthria Ragonot, and Rampylla Dyar.
