Autocartes aeneus (Family: Trictenotomidae)
Even some specialist coleopterists, when they hear the name “trictenotomids”, don’t quite know what to say: “Who?+ Is that a fact?!” Some might take them for a variety of longhorn beetle, or stag beetle. There are only a few people around with a “personal” knowledge of these interesting representatives of the order of Coleoptera.
The family of trictenotomids is a classic example of a small family with a distinct and restricted area of distribution. There are currently just 14 recent representatives of this family known to science. As yet, no fossil species of trictenotomids have been discovered. All the contemporary species have been encountered in the Oriental zoogeographical region, and only a few of them have distribution areas that extend into the South-Eastern Palaearctic.
