Smallest and oldest false skin beetle: Paleobiphyllus ponomarenkoi gen. et sp. nov. (Coleoptera: Cleroidea: Biphyllidae) from Santonian Taimyr amber, northern Russia

A new species of the genus Trematosphindus Li et Cai, 2021 (Coleoptera: Sphindidae) from Cenomanian Taimyr amber

“…Flora of Taimyr amber forests is nearly unknown (Jenkins Shaw et al 2024 and references therein), but supposedly was similar well-studied Turonian flora from Novaja Sibir (Telnov et al 2024). The single Taimyr Cretaceous mycelium was described from Yantardakh (Kheta Formation) (Sukhomlyn & Perkovsky 2023), and mycophagous beetles are not numerous or diverse (Makarov & Perkovsky 2020, Sukhomlyn & Perkovsky 2023. New finding adds sphindids to this list.…”

“…Taimyr amber localities and their faunas were in the 21th century reviewed by Rasnitsyn et al (2016) and Perkovsky & Vasilenko (2019), with additions by Vršanský (2019), Telnov et al (2024) and Ogłaza et al (2024) based on the collections from different regions and formations of the Taimyr Peninsula, Azar & Maksoud (2020), Fedotova and Perkovsky (2020), Makarov & Perkovsky (2020), Colombo et al (2021), Melnitsky & Ivanov (2021, Giłka et al (2022), Ogłaza et al (2022a, b), Sukhomlyn & Perkovsky (2023) and Jenkins Shaw et al (2024) on Kheta Formation localities, Khaustov et al (2023) on Baikura, Kolibáč and Perkovsky (2020) on Zhdanikha, Hakim et al (2021) and Melnitsky & Ivanov (2022a) on Nizhnyaya Agapa. The Sphindidae is 47 th arthropod family reported from Nizhnyaya Agapa.…”

First carnivorous fungus from Santonian Taimyr amber

“…2017; Peris 2020 and references therein). Unlike these, much more northern Taimyr amber inclusions are poorer in mycetophages, both in number and taxonomic diversity (Blagoderov & Grimaldi 2004; Makarov & Perkovsky 2020). This paper describes the first fungus from the Taimyr amber, except a supposed fungus upon beetle Paleobiphyllus ponomarenkoi Makarov & Perkovsky, 2020 (Biphyllidae) collected in the same Lagerstätte in 2012 (Makarov & Perkovsky 2020, Fig.…”
