Caddisflies from Cenozoic resins of Europe

Only a half of Species of Hymenoptera in Rovno Amber Fauna is Common with Baltic Amber

“…In summary, the above numbers concerning all Hymenoptera confi rm the previously proposed suggestion on the diff erent origins of the four main European sources of succinite (Dlussky & Rasnitsyn, 2009;Perkovsky, 2011Perkovsky, , 2016Ivanov et al, 2016;Wolfe et al, 2016;Sokoloff et al, 2018). Considering that there is no reliable evidence of succinites being of inequal ages, the diff erences in origin should be considered geographically determined, a theory supported by several studies (Wolfe et al, 2016;Nadein et al, 2016;Jałoszyński & Perkovsky, 2016;Perkovsky, 2016Perkovsky, , 2017Mänd et al, 2018).…”

“…Th e fauna of Baltic amber forest is a mix of extant temperate and tropical elements, and temperate elements strongly prevail (Archibald & Farrell, 2003;Perkovsky, 2011Perkovsky, , 2013Perkovsky, , 2016Perkovsky, , 2017Ivanov et al, 2016), so the climate of Baltic amber forest was probably not favorable for the extant tropical genera like Pristomyrmex (40 Oriental and New Guinea species, other 20 species Afrotropical, Australian and Oceanian) now known from all late Eocene ambers, except Baltic (Radchenko, Dlussky, 2018 b). Th e same distribution is known for Fallomyrma with type species in Rovno, Bitterfeld and Scandinavian ambers and three additional species in southernmost Rovno amber (table 1).…”

A new genus of fungus weevils (Coleoptera: Anthribidae) in Rovno amber

“…Some tropical elements from Bitterfeld and Rovno amber, e.g. Thallisellini (Erotylidae: Languriinae), the Litochropus genus group (Phalacridae) Perkovsky, 2016, 2017) and the extremely thermophilic (Vladimir Ivanov, personal communication, 2013) trichopteran genus Leptocerus Leach, 1815 (Ivanov et al, 2016) are unknown from Baltic amber.…”

The first fossil Coleoptera record from the Volyn Region, Ukraine, with description of a new Glesoconomorphus (Coleoptera, Mycteridae) in syninclusion with Winterschmidtiidae (Acari) and a key to species

“…The type species of Glesoconomorphus from Baltic amber is named after “Nachzehrer”, a mystical vampire from the folklore of Germany and Poland that, according to the legend, first persecutes and then murders its natural relatives ( Alekseev et al 2019 ). We can only speculate that individuals of the type species could not cross the ancient sea and reach the Volyn area ( Ivanov et al 2016 , fig.1), where Glesoconomorphus ekaterinae sp. nov., the first of the Rovno amber mycterids, dwelled.…”
