REMARK

This species does not seem to be attracted by lights. The female specimen was collected by sight and the male specimen with a glass interception trap. Also Grazia (1983) did not mention the use of light traps to collect the three specimens observed, 1 ♀ & 1 ♂ from Brazil and 1♀ from Surinam. This species is photographed for the first time. The dorsal color of the female collected is globally red although the color of the male is mostly dark orange.
