Abstract

Baetodes santatereza, new species, and B. liviae, new species, are described based on nymphs collected from São Paulo, and Paraná states, Brazil. They both possess one gill on each coxa and tubercles on metanotum and abdominal segments 1 – 9. Besides these characteristics, they can be distinguished from the other known species of the genus by the following combination of characters: B. santatereza, n. sp., glossae with two bladelike setae, one pectinate and one nonpectinate, and dorsal edge of femora with five to seven clavate setae, nearly one half the length of long, fine setae; B. liviae, n. sp., glossae with one pectinate bladelike setae, dorsal edge of femora often with 6 to 8 clavate setae, nearly the length of long fine setae, besides body color pattern and body length.
