Type material. Holotype, female, Venezuela, Territorio Federal (T. F.), Departamento Amazonas, Río Negro-Río Baria, 140 m, 0◦55’N – 66◦10’W, 25-III-15-IV-1984, C. Padilla ( IZAV). Paratype, 1 female, same data as holotype ( UNAM).

Distribution. Ven ez uel a.

Diagnosis. This new species is related to C. excavata Brailovsky & Barrera by having the pronotal disk without yellowish orange or black median longitudinal stripe, and corium without median yellowish transverse fascia. In C. excavata the antennal segments II and III are dark to pale castaneous orange, the humeral angles subacute, the total body length less than 13.00 mm., and the length of antennal segment IV less than 4.40 mm. In C. refulgens sp. nov., the total body length is longer than 16.00 mm., the length of antennal segment IV longer than 4.50 mm., the antennal segments II–III dark reddish brown, and humeral angles rounded.
