Examining a fragment of the Rovno amber, scientists from Russia and Ukraine have described a new species of beetles of skrytogo the time of the Eocene geological period, which ended in 39 million years ago.
The discovery helped to restore the early stages of the evolution of the genus Telmatophilus insects — the beetle, apparently, is the most ancient representative of it.
Rovno amber experts called the southern counterpart of the Baltic amber and dated to the period of late Eocene (about 40 million years ago). Research Rovno samples began relatively recently, but has helped to describe several new species of insects: beetles, lacewing (Neuroptera) and verbluda (Raphidioptera).
Employee of the Zoological Museum of Moscow state University Georgy Lyubarsky and representative of the Ukrainian Institute of Zoology, the name of Evgeny Perkovsky Schmalhausen studied fragment of the Rovno amber, found in the flood plain fun. It was concluded small beetle. The sample was very high quality and sufficiently transparent in order to examine in detail the anatomical features of an insect.
Scientists have determined that the beetle belongs to the family of skrytogo (Cryptophagidae). Externally it was very similar to modern beetles Telmatophilus typhae. However, some features, including relatively long antennae and the structure of the legs, allowed to attribute the discovery to a new kind of the same kind. The species got the scientific name Telmatophilus sidorchukae.
According to lubarsky, the beetle from Rovno amber is the first fossil representative of the genus Telmatophilus. Before this was known only to living species.
Hummingbirds were able to remember the sequence of numbers
The discovery helped to reconstruct the evolutionary history of the genus Telmatophilus. Unlike other members of the family, these beetles do not feed on mold and fungi, and pollen of cattail (Typha) and euholognatha (Sparganium).
According to the authors, the beetles of the genus Telmatophilus arose in the late Eocene, when the background of global cooling climate in Northern Eurasia appeared numerous lakes, where they spread cattail, half-sunk agegraphic and other marsh plants.
