Key to species of Nannicerus (males)

1. UFS apex reaching ocelli ( Figs. 16 , 32 ); all femora, each with a median black spot ( Figs. 18 , 34 ); process of anal tube short and slender ( Figs. 21 , 37 ).................................................................................. 2

- UFS apex not reaching ocelli ( Fig. 2 ); femora without black spots ( Fig. 4 ); process of anal tube long and robust ( Fig. 6 ).................................................................. Nannicerus gracilis Maldonado-Capriles, 1977

2. Apodeme of sternite II longer than sternite II ( Fig. 20 ); connective without apical longitudinal keel ( Fig. 25 ); dorsal apodeme of aedeagus with subtriangular apex ( Fig. 27 ); laterobasal process of anal tube with truncated apex ( Fig. 21, 30 )................................................................................................ N. curica sp. nov.

-. Apodeme of sternite II shorter than sternite II ( Fig. 36 ); connective with apical longitudinal keel ( Fig. 41 ); dorsal apodeme of aedeagus with pointed apex ( Fig. 43 ); laterobasal process of anal tube with pointed apex ( Fig. 37, 46 ).... N. grandis sp. nov.
