New Taxa of Chrysomelidae (Insecta: Coleoptera) from Rovno Amber, Late Eocene

Abstract

Leaf beetles Chrysomelidae of Rovno amber, from the Late Eocene, are recorded and described. Chrysomelidae of Rovno amber are represented by three subfamilies: Galerucinae (Alticini), Chrysomelinae, and Eumolpinae. Two new genera and three new species of Alticini: Manobiomorpha Nadein, gen. nov. (type species Manobiomorpha eocenica Nadein, sp. nov.), Psyllototus Nadein, gen. nov. (type species Psyllototus progenitor Nadein, sp. nov.), and Crepidodera decolorata Nadein et Perkovsky, sp. nov. are described. A new chrysomeline genus and species Paleophaedon minutus Nadein gen. nov. et sp. nov. is described. Probable trophic association of Crepidodera decolorata sp. nov., the taxonomic positions of Manobiomorpha gen. nov. and Psyllototus gen. nov., and the composition of leaf beetle faunas of Middle and Late Eocene of Europe are discussed.

New Late Eocene Chrysomelidae (Insecta: Coleoptera) from Baltic, Rovno and Danish ambers

“…Psyllototus is a fossil genus closely related to the recent Psylliodes Latreille, 1829, from which it differs in having 11‐segmented antennae, while Psylliodes bears 10‐segmented antennae. Three species, Psyllototus progenitor Nadein in Nadein and Perkovsky, from Rovno amber, Psyllototus doeberli Bukejs and Nadein, and Psyllototus groehni Bukejs and Nadein, from Baltic amber have been described. The new species is a fourth representative of the genus.…”

Systematics of Manobiina with cladistic analysis based on morphological data (Coleoptera: Chrysomelidae: Galerucinae: Alticini)

“…The age of this flea beetle described from Rovno amber is dated as Late Eocene (approx. 37 million years ago) from northwest Ukraine (Nadein & Perkovsky 2010). Habitually, Manobiomorpha is similar to Lipromima and some species oí Manobia.…”

Possible living fossil in Bolivia: A new genus of flea beetles with modified hind legs (Coleoptera, Chrysomelidae, Galerucinae, Alticini)

“…Remarkably, based on the characters that are available for observation, among all the flea beetles, the only one with combination of 11 antennomeres and the first metatarsomere attached to the metatibia at a significant distance from its apex is a recently described from Baltic amber, extinct flea beetle genus Psyllototus Nadein (in Nadein and Perkovsky 2010). Although, details of the Psyllototus head and ventral side of the body are not available for study.…”
