Two new species, C. maracatu, sp. nov. and C. spaceki, sp. nov., are described, the former based on nymphs and reared adults and the latter only on nymphs; the male and fe- male imago of C. auwe and the female imago of C. redactus are described. Based on these findings, an updated key for South American nymphs and male adults of the two-winged Cloe- odes is provided.
