Professor Edmundno Barnes holds a beetle named titan beetle (lat. Titanus giganteus). This species is among the largest of beetles known to science. Most sources of adult length specified within 79 to 168 mm. Other sources cite different maximum length - from 170 to 210 and even up to 220 mm. Accurate scientific evidence was not available yet. The average length of most individuals is 130 mm, it is much rarer specimens up to 150 mm. Cost of dried specimens as large as possible for the entomological collections can reach more than US $ 1,000. Titan beetle is distributed throughout the Amazon - Peru, Ecuador, Colombia, Surinam and Guyana to Bolivia and the middle part of Brazil. The morphology of the larvae is unknown, as they have not yet been discovered.
