Description
The basic coloration is dark brown. The eyes are large and the pronotum is yellowish or pale brown, with a blackish area in the middle and small backward-pointing teeth. These beetles are bioluminescent by means of two luminescent light organs at the posterior corners of the prothorax, emitting green light, and a large abdominal area on the first segment, emitting yellow light. They emit light continuously and do not flash. The eggs and pupae are also bioluminescent.
Distribution
This species can be found in Argentina and Brazil.
