description: This dataset contains the digitized treatments in Plazi based on the original journal article Legalov, Andrei A., Nazarenko, Vitaliy Y., Perkovsky, Evgeny E. (2021): A new species of the genus Glaesotropis Gratshev and Zherikhin, 1995 (Coleoptera, Anthribidae) from Rovno amber. Fossil Record 24 (1): 1-7, DOI: 10.5194/fr-24-1-2021, URL: http://dx.doi.org/10.5194/fr-24-1-2021Abstract. A new fungus weevil, Glaesotropis (Electranthribus) rohdendorfi sp. nov. (Coleoptera: Anthribidae), is described from Priabonian Rovno amber. It is similar to G. (E.) zherikhini (Legalov, 2013a) but differs in the transverse carina extending to the scutellum, shorter antennomere 2, wider antennal club, more convex eyes, and larger body size. It is the first record of the subgenus Electranthribus Legalov, 2013a from Rovno amber, the first named beetle from the Olevsk amber locality, and the sixth amber species reported from the Zhytomyr region. An aggregation of glaesacarid mites Glaesacarus rhombeus (Koch and Berendt, 1854) as a syninclusion with the fungus weevil is reported for the first time (41 specimens); the possibility of the glaesacarids feeding on fungi is discussed.1 IntroductionThe family Anthribidae (fungus weevils) is a small group of quite primitive Curculionoidea with more than 3800 extant species (Rheinheimer, 2004). It has five subfamilies (Legalov, 2015, 2018a). Subfamilies Juranthribinae and Protoscelinae are extinct, known from the Middle–Late Jurassic of Karatau, Kazakhstan (Legalov, 2011b, 2013b; Medvedev, 1968). Compression fossils of the subfamily Urodontinae have been reported from Priabonian (late Eocene)– Chattian (late Oligocene) of Europe (Hieke and Pietrzeniuk, 1984; Legalov, 2020c). Extinct taxa of the subfamily Choraginae have been described from the Early Cretaceous of Spain (Soriano et al., 2006), the Eocene of North America (Scudder, 1890), and the Eocene (Legalov et al., 2018) and latest Oligocene of Europe (Heyden and Heyden, 1866). The subfamily Anthribinae is well presented in the fossil record. The oldest forms are known from the mid-Cretaceous (Zherikhin, 1993; Legalov et al., 2019b, and references therein) and the Turonian–Coniacian (Legalov, 2020b) of the Russian Far East. Thirteen species are described from the Ypresian (early Eocene) of the USA and France (Scudder, 1893; Legalov et al., 2019a; Legalov, 2018b, 2020c) and 14 from Priabonian ambers (Voss, 1953; Zherikhin, 1971; Gratshev and Zherikhin, 1995; Gratshev and Perkovsky, 2008; Legalov, 2012, 2013 a, 2015, 2020a). The subfamily has been found in Miocene Mexican and Dominican ambers (Poinar and Legalov, 2016; Legalov et al., 2019b).Two species of fungus weevils are known from Priabonian Rovno amber (Gratshev and Perkovsky, 2008; Legalov et al., 2018). Here, we describe a third anthribid species from this amber. Seventeen curculionoid species are reported from Rovno amber, all unknown from Baltic amber; besides Anthribidae, these include one species of Rhynchitidae (Bukejs and Legalov, 2019b), one of Brentidae (Bukejs and Legalov, 2020), nine of Curculionidae (Nazarenko and Perkovsky, 2009, 2016; Nazarenko et al., 2011; Bukejs and Legalov, 2019a; Legalov et al., 2019c), and three of Scolytidae (Petrov and Perkovsky, 2008, 2018). Half of the Rovno amber curculionoid genera (7 of 14) are unknown from Baltic amber (Legalov, 2020c).Both earlier described species were collected in the Rovno region, one in Klesov and the second in Klesov or Dubrovytsya (Jałoszyński and Perkovsky, 2016, fig. 37). The new anthribid is the first amber beetle described from the Zhytomyr region; only two new genera and four new species of gall midges (Fedotova and Perkovsky, 2015, 2017) and one caddisfly (Perkovsky, 2017) were determined to the species level from Zhytomyr region localities (Olevsk and Gulyanka) until now. The biota from these localities is quite important, as confidently dated plant fossils are also known from the same area (Sokoloff et al., 2018, and references therein).
