Comments. The terminalia of C. nodicornis was described based on additional material, once the holotype terminalia was not dissected.
Carrera (1946) wrongly designated a neotype (Nº 108.337) and an allotype (Nº 108.338), both from Batatais, São Paulo state, Brazil. Furthermore, Carrera (1946) studied 35 specimens (93, 26♀, Nº 108.339–108.373) from the same locality. Here, We also analysed some specimens from Batatais without any label informed above.
