Remarks: C. bergi is the best known species in the family, with 6 to 10 mm length and the biology well described ( Riis et al. 2005; Riis & Esbjerg 1998), This species is widely distributed in South and Central America ( Froeschner 1960; Schwertner & Nardi 2015) and has been reported as pest in several countries feeding on peanut, corn and cassava ( Riis et al. 2003; Stock et al. 2005), seriously affecting production ( Melo Molina et al. 2006). Individuals are found buried in soil and are collected in light trap.

C. bergi presents similar morphological characteristics with C. mirabilis but differs in the proportion between the width of the ocellus and the distance between the ocellus and the eye, which is greater for C. mirabilis . According to studies that are being developed by the authors, the characteristic proposed by Froeschner (1960) is not enough for accurate identification, but it was used in this paper for naming the specimens included. Also, new records are based in specimens previously identified by researchers and deposited in the collections examined.
