Etymology. The new species is named in honor to Dr. Ricardo Monteiro, insect ecologist and one of the collectors of type specimens. He kindly made available extensive leafhopper material from Malaise traps placed along an altitudinal gradient at PNI.

Taxonomic notes. Curtara (Curtara) monteiroi sp. nov. resembles Curtara (Curtara) serrana DeLong, 1980 , in color with dark maculae on anterior margin of pronotum, with dark punctures on disc ( Figs 52 , 65 ) and forewing with dark mottled maculae ( Figs 55 , 68 ); simple style, with apical portion curved dorsally ( Fig. 62 ), and, aedeagus with shaft close to the dorsal apodeme with a pair of ventral apical processes, directed ventrally ( Fig. 63 ). Curtara (Curtara) monteiroi sp. nov. differs from Curtara (Curtara) serrana mainly by the truncated apex of male pygofer with a process on the posterodorsal margin ( Fig. 58 ), while the apex of the pygofer of Curtara (Curtara) serrana is bluntly pointed; and by shape of atrial processes of aedeagus, which in Curtara (Curtara) monteiroi sp. nov. they are delicate and slender ( Fig. 63 ) and in Curtara (Curtara) serrana they are more robust.

Curtara (Curtara) monteiroi sp. nov. was collected at PNI at altitudes from 1,142 to 2,255 m a.s.l.
