A new genus and species of Lebiini (Coleoptera: Carabidae) from late Eocene Rovno amber

First fossil species of ship-timber beetles (Coleoptera, Lymexylidae) from Eocene Rovno amber (Ukraine)

“…Late Eocene Rovno amber from Ukraine is the southern coeval of the famous Baltic amber (Sokoloff et al 2018), and more than 300 arthropod species have already been described from there (Perkovsky 2018;Bukejs et al 2020;Colombo et al 2021aColombo et al , 2021bKhaustov et al 2021a, 2021b andreferences therein). Fewer than 48% of Rovno hymenopteran species (Simutnik et al 2020(Simutnik et al , 2021Colombo et al 2021aColombo et al , 2021bColombo et al , 2021cRadchenko et al 2021, our data), 32% of caddisfly species (Melnitsky et al 2021a(Melnitsky et al , 2021b(Melnitsky et al , 2021c, 24% of Nematocera (Giłka et al 2021), and less than 15% of beetle species (Legalov et al 2021a(Legalov et al , 2021bKirichenko-Babko et al 2021, 2022Kupryjanowicz et al 2021;Lyubarsky and Perkovsky 2021;Telnov et al 2021;Tshernyshev and Perkovsky 2021;Perkovsky et al 2022;this paper) are shared with Baltic amber fauna. Nearly all studied Rovno amber inclusions from the Rovno Region were collected from Klesov and the Horyn River Basin (Perkovsky et al 2010;Perkovsky 2017a;Mitov et al 2021), except new collections from Varash District (former Vladimirets and Zarechnoye Districts) in the Rovno Region and the former Manevichi District in the Volyn Region (Styr, Veselukha, and Stokhod River Basins).…”

The first neotropical ground beetle (Coleoptera, Carabidae) from the Eocene of Ukraine: finding the first Old World ant nest beetle related to Eohomopterus in the Rovno amber

“…2022), an extinct lebiine genus known only from Rovno amber with two species (Kirichenko-Babko et al . 2022a, b) and the new tropical paussine (Kirichenko-Babko & Perkovsky 2021) described here.…”

New findings of Cryptophagidae (Coleoptera: Clavicornia) from Baltic amber in the unbiased collection of the Paleontological Institute of RAS

“…Among Rovno beetles only 13% are species known from Baltic amber [Kupryjanowicz et al, 2021;Legalov et al, 2021;Kirichenko-Babko et al, 2021;this paper]; as was supposed [Bukejs et al, 2020] many Baltic beetles would be found in Rovno amber, as is the case with Bitterfeld amber [Bukejs et al, 2016], however it is highly likely that some Holarctic taxa from Baltic amber were absent in Rovno fauna (and A. groehni could belong to this group). On the other hand, some beetles from Holarctic genera, described from Rovno amber, can be found in Baltic amber, as Crepidodera [Bukejs et al, 2016] and Micrambe sarnensis.…”
