Crepidodera decolorata is an extinct species of flea beetles described from the late Eocene Rovno amber of Ukraine. [1]
Scydmaeninae are a subfamily of small beetles, commonly called ant-like stone beetles or scydmaenines. These beetles occur worldwide, and the subfamily includes some 4,500 species in about 80 genera. Established as a family, they were reduced in status to a subfamily of Staphylinidae in 2009
Baltic amber or succinite is amber from the Baltic region, home of its largest known deposits. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that this forested region provided the resin for more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014 and 400 tonnes in 2015.
Smicripidae is a family of beetles, in the superfamily Cucujoidea. The common name for this family is palmetto beetles. The family only has one extant genus, Smicrips, with six extant species native to tropical and subtropical regions of the Americas and extinct species from the Eocene of Europe and one extinct genus, Mesosmicrips, known from the mid Cretaceous aged Burmese amber. Smicrips larvae are usually found amongst decaying vegetation, while adults are typically found on inflorescences, especially those of Arecaceae (palms), although associations with flowers of Fabaceae (legumes), Passifloraceae, Bombacaceae and Cactaceae (cactus) have also been recorded. Their diet is unknown.
Manobiomorpha is an extinct genus of flea beetles described from the late Eocene Rovno amber of Ukraine. It was named by Konstantin Nadein and Evgeny Perkovsky in 2010, and the type species is Manobiomorpha eocenica.
Psyllototus is an extinct genus of flea beetles described from the late Eocene Rovno amber of Ukraine, and from the Baltic amber of Russia and Denmark. It was named by Konstantin Nadein and Evgeny Perkovsky in 2010, and the type species is Psyllototus progenitor. In 2016, a newly described extant flea beetle genus from Bolivia, Chanealtica, was found to be most similar to Psyllototus, based on the characters available for observation.
Paleophaedon is an extinct genus of chrysomeline leaf beetle described from the late Eocene Rovno amber of Ukraine. It was named by Konstantin Nadein and Evgeny Perkovsky in 2010, and the type species is Paleophaedon minutus.
Glipostena ponomarenkoi is an extinct species of beetle in the genus Glipostena. The species was described from the late Eocene Rovno amber of Ukraine in 2009.
Lepidotrix is an extinct genus of wingless insect belonging to Zygentoma in the family Lepidotrichidae. There is one described species in Lepidotrix, L. piliferum/pillifera. It is known from specimens found in Eocene aged Baltic amber and Rovno amber. The genus lacks occelli. Its relationship with the extant genus Tricholepidion, which has historically been placed in the same family, is disputed, with some studies finding the two taxa to not be closely related, with Tricholepidion being placed in its own family instead. While often spelled Lepidothrix in historic literature, this is homonymous with a genus of birds, and Lepidotrix was the spelling used in the original publication.
Embolemidae is a family of small solitary parasitoid wasps with around 70 species in 2 genera distributed around the world. The few species whose biology is known are parasites on planthopper nymphs of the families Achilidae and Cixiidae. There is debate regarding the status of the genus named Ampulicomorpha by Ashmead in 1893, generally considered now to be a junior synonym of Embolemus (e.g.,), though some authorities dispute this (e.g.,)
Pachycondyla succinea is an extinct species of ant in the formicid subfamily Ponerinae described from fossils found in Europe. P. petrosa is one of three middle Eocene Pachycondyla species found in Baltic amber.
Rovno amber, occasionally called Ukrainian amber, is amber found in the Rivne Oblast and surrounding regions of Ukraine and Belarus. The amber is dated between Late Eocene and Early Oligocene, and suggested to be contemporaneous to Baltic amber. Major exploration and mining of the amber did not start until the 1990s.
Alicodoxa is an genus of extinct planthoppers in the family Dictyopharidae. It contains a single described species, Alicodoxa rasnitsyni, known from several Late Eocene fossils found in Europe.
Nylanderia pygmaea is an extinct species of formicid in the ant subfamily Formicinae known from fossils found in the Prussian Formation of the Baltic region.
Paleomolpus is an extinct genus of leaf beetles in the subfamily Eumolpinae. It contains only one species, Paleomolpus hirtus. It is known from late Eocene amber from Denmark. The generic name is derived from the Ancient Greek palaios and -molpus. The specific name, Latin for hairy, refers to the pubescent dorsum of the species.
Taphioporus is an extinct genus of leaf beetles in the subfamily Eumolpinae. It is known from Baltic and Rovno amber from the upper Eocene.
Winnertziinae is a subfamily of gall midges and wood midges in the family Cecidomyiidae.
Proneuronema is an extinct genus of lacewings in the neuropteran family Hemerobiidae known from fossils found in amber. The genus currently contains three species, P. gradatum and P. minor from Baltic amber and P. sidorchukae from Rovno amber. A Ypresian fossil from Washington state was initially also placed within the genus, having been moved from its original placement as Cretomerobius wehri, but was subsequently moved to the separate genus Archibaldia by Vladimir Makarkin (2023).
Empheriidae is an extinct family of Psocoptera in the suborder Trogiomorpha.
The Mezhigorje Formation is a geologic formation in Belarus and Ukraine that dates to the Early Oligocene. Rovno amber is found in this formation and it has been studied since the 1990s.
The Obukhov Formation is a geologic formation in Belarus and Ukraine that dates to the Late Eocene; the Obukhov Formation is equivalent to the Prussian Formation of Russia.
