A new genus of the subfamily Languriinae (Coleoptera: Erotylidae) from the Late Eocene Baltic amber

Abstract

Thallisellites olgae gen. et sp. n. (Erotylidae: Languriinae, Thallisellini) is described from the Late Eocene Baltic amber. Extant species of the tribe Thallisellini are all of a neotropical distribution. The new genus is similar to the extinct Serramorphus Lyubarsky et Perkovsky, 2017 from Bitterfeld amber. The new genus differs from Serramorphus by the smooth, rounded and not dentate lateral margin of the pronotum (in Serramorphus, the lateral margin is sinuous and spinose). New genus is considered monotypic and differs from extant genera of Thallisellini primarily in the strongly developed anterolateral angles of the pronotum. Family Tarsonemidae (Acari) is reported from the Baltic amber for the first time.

A new species of Bocchus from upper Eocene Rovno amber (Hymenoptera, Dryinidae)

“…In addition, one specimen from Varash district could not be determined to the species level. This difference might be related to the climate of the Rovno amber forest being warmer than that of the Baltic amber forest (Kupryjanowicz et al 2022;Yamamoto et al 2022; and references therein), especially since their potential hosts (i.e. Tropiduchidae) are mainly tropical and subtropical (Bourgoin 2020).…”

Unexpected Diversity of Xenoscelinae in Priabonian European Amber: The Third Xenosceline Species from Rovno Amber

“…Several Erotylidae fossils are known from the late Eocene amber faunas: erotyline Triplax contienensis Alekseev, 2014, languriine Serramorphus rasnitsyni Lyubarsky & Perkovsky, 2017, and xenosceline Microzavaljus saxonicum Lyubarsky & Perkovsky, 2018 in Bitterfeld amber [ 9 , 10 , 11 ], languriine Thallisellites olgae Kupryjanowicz, Lyubarsky & Perkovsky, 2021 in Baltic amber, Cycadophila mumia Alekseev, 2017 (Pharaxonothinae), xenoscelines Warnis tvanksticus Lyubarsky, Perkovsky & Alekseev, 2016 and Xenophagus popovi Lyubarsky & Perkovsky, 2017 in Baltic amber [ 12 , 13 , 14 , 15 ], xenoscelines Xenohimatium rovnense Lyubarsky & Perkovsky, 2012 [ 16 ], the new species of Xenophagus Lyubarsky & Perkovsky, 2017 described in the present paper, and Zavaljus lyubarskyi Alekseev & Bukejs, 2022 [ 17 ] in Rovno amber.…”

Celebration time: here’s to 500 numbers of Far Eastern Entomologist

“…Over the last three years, 210 articles have been published in the journal, of which 62% (130 articles) were taxonomic works describing new taxa and establishing various nomenclatural acts for recent insects (Daniel et al, 2021;Gorochov, 2021Gorochov, , 2022Jaitrong et al, 2022;Storozhenko, 2023;Grichanov, 2023;Lelej, 2023, etc. ) as well as for fossil forms (Rasnitsyn & Aristov, 2021;Kupryjanowicz et al, 2022;Aristov & Gorochov, 2022, etc.). In total, in 2021-2023, one tribe, 23 genera and subgenera, and 158 species and subspecies of insects, one genus and four species of spiders, two species of oribatid mites and one species of diplopod were described in the journal.…”
