Colaspoides Picticornis
''Colaspoides'' is a genus of leaf beetles in the subfamily Eumolpinae. It is one of the largest genera in the subfamily, containing over 260 species worldwide. It is an extant genus but there is at least one species, ''C. eocenicus'', found in Baltic amber from the Upper Eocene of Russia, and the genus has also been reported from the Miocene of the Dominican Republic. According to Flowers (2018), the Old World species of ''Colaspoides'' have morphological similarities with ''Beltia'', which indicates that they must be eventually placed in a different genus or genera. Species The genus contains the following species: Neotropical species: * ''Colaspoides abdominalis'' Martin Jacoby, Jacoby, 1900 * ''Colaspoides alcyonea'' (Wilhelm Ferdinand Erichson, Erichson, 1847) * ''Colaspoides amabilis'' Édouard Lefèvre, Lefèvre, 1876 * ''Colaspoides amazona'' Martin Jacoby, Jacoby, 1881 * ''Colaspoides batesi'' Martin Jacoby, Jacoby, 1879 * ''Colaspoides bicolor'' (Guillaume-Antoine Ol ...

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...
