First record of the subfamily Sagrinae (Coleoptera: Chrysomelidae) from the Eocene of North America

A new genus, Palaeatalasis gen. nov. (type species P. monrosi sp. nov.), from the tribe Megamerini (Chrysomelidae: Sagrinae) from the early-middle Eocene Green River Formation is described and illustrated. The new genus is similar to the Recent Atalasis Lacordaire, 1845 but differs from it in the subparallel sides of the pronotum, metafemora without teeth, and non-emarginate eyes. It differs from the Eocene Eosagra Haupt, 1950 in the large, convex, non-emarginate eyes, wide elytra, and transverse pronotum. The new genus is distinguished from the Paleocene Gallopsis Legalov, Kirejtshuk et Nel, 2019 in the wide forehead and convex eyes. It is the first record of the Sagrinae from North America and the fourth known species of the family Chrysomelidae from the Green River.</p

Stenommatus sokolovi n. sp. se caracteriza por poseer las interestrías elitrales tan anchas como el ancho de las estrías; pronoto finamente punteado y aedeago pequeño, ancho, redondeado en su ápice y endofalo sin escleritos. Se propone una clave para las especies sudamericanas del género Stenommatus.The weevil tribe Dryophthorini is reported in Peru for the first time. Two species from Satipo, Junin, Stenommatus chabooae Legalov n. sp. and Stenommatus sokolovi Legalov n. sp., are herein described. Stenommatus chabooae Legalov n. sp. is characterized by having the elytral interstriae narrower than striae width; pronotum coarsely punctate; large, narrow aedeagus, weakly curved at apex, with a large basal sclerite of the endophallus. Stenommatus sokolovi is characterized by having the elytral interstriae as wide as striae width; pronotum finely punctate; small, wide aedeagus, rounded at apex and endophallus lacking sclerites. A key to the South American species of the genus Stenommatus is given

First record of the tribe Naupactini (Coleoptera: Curculionidae) in Rovno amber

A new weevil, Arostropsis perkovskyi Bukejs and Legalov, sp. nov. (urn:lsid:zoobank.org:act:408ECE71-B191-4381-AA39-C27A3A1DA082; Coleoptera: Curculionidae: Entiminae), is described from Late Eocene Rovno amber. The new species differs from Arostropsis groehni Yunakov et Kirejtshuk, 2011 from Baltic amber in the pronotum lacking a distinct lateral ridge, it has a shorter rostrum, antennomere 2 is subequal to antennomere 3, it has wider elytra with weaker convex humeral calli and the pronotum is wider than it is long. It is the first record of the tribe Naupactini in Rovno amber and the second finding of Arostropsis in Eocene ambers.</p

The first record of Brentidae (Coleoptera) in Eocene Rovno amber with description of a new fossil species of <i>Toxorhynchus</i> Scudder, 1893

A new pear-shaped weevil, Toxorhynchus europeoeocenicus Bukejs et Legalov, sp. nov. (Coleoptera: Brentidae: Apioninae), is described from upper Eocene Rovno amber using X-ray microcomputed tomography (µCT). The new fossil species differs from the extinct Toxorhynchus robustus Poinar et Legalov, 2015 (Dominican amber, lower Miocene) in the larger body size, narrower elytral striae, and wider pronotum. It is the first record of the family Brentidae in Rovno amber and the first record of the genus Toxorhynchus in the eastern hemisphere (urn:lsid:zoobank.org:pub:8FB7B299-EE75-4556-B4EA-203A3CBED84C).</p

New genus of the tribe Ceutorhynchini (Coleoptera: Curculionidae) from the late Oligocene of Enspel, southwestern Germany, with a remark on the role of weevils in the ancient food web

The new weevil genus Igneonasus gen. nov. (type species: I. rudolphi sp. nov.) of the tribe Ceutorhynchini (Curculionidae: Conoderinae: Ceutorhynchitae) is described from the late Oligocene of Fossillagerstätte Enspel, Germany. The new genus differs from the similar genus Stenocarus Thomson, 1859 in the anterior margin of the pronotum, which is not raised, a pronotum without tubercles on the sides, and a femur without teeth. This weevil is the largest representative of this supertribe and the first fossil Curculionidae species described from the paleolake Enspel. In this ancient ecosystem, weevils were at least sometimes an important food resource for the cyprinid fish Palaeorutilus enspelensis.</p

A new species of the genus Dorytomus Germar, 1817 (Coleoptera: Curculionidae) from Baltic amber

A new species, Dorytomus groehni Bukejs &amp; Legalov sp. n. is described and illustrated from Eocene Baltic amber. The new species differs from D. nudus Legalov, 2016 primarily in longer and wider body size, narrower and longer rostrum, slightly convex interstriae distinctly wider than elytral striae and finely punctate pronotum with semierect setae

Groehnius, a new genus of Eugnomini (Coleoptera: Curculionidae) from Eocene Baltic amber

A new weevil, Groehnius electrum Bukejs and Legalov, gen. et sp. nov. (Coleoptera: Curculionidae: Curculioninae), is described from Eocene Baltic amber. This new genus is similar to the genus Archaeoeugnomus Legalov, 2016 from Baltic amber but differs in the femora without ventral teeth, and the scape not reaching the anterior margin of the eye. It is the second record of the tribe Eugnomini in the Eocene
