The very abundant representatives of the genus Malthodes Kiesenwetter, 1852 from the Eocene amber forests show a remarkable diversity of body forms, especially regarding the last abdominal segments, both tergites and sternites. These structures are important during the mating. In the present work, we describe a new species, Malthodes gedanicus sp. nov. characterized by the last sternite elongated and apically divided into two long and flat squarish lobes with three tips of which the central is longest, and by the last tergite elongated and spatuliform apically. The phylogenetic relationships based only on the shape of the last abdominal segments remain unclear and the new species is very vaguely similar to M. trifurcatus Kiesenwetter, 1852.

A new species of the extant spider family Anapidae is described from a fossil mature male in Eocene amber from the Baltic region and tentatively assigned to the genus Balticoroma Wunderlich, 2004. Phase contrast X-ray computed micro-tomography was used to reveal important features that were impossible to view using traditional microscopy. Balticoroma wheateri new species is easily diagnosed from all other anapids by having clypeal extensions that run parallel to the ectal surface of the chelicerae and in having the metatarsus of the first leg highly reduced and modified into what is presumably a y-shaped clasping structure. Although only a single extant anapid species occurs in northern Europe, the family was diverse in the Eocene. The discovery of yet another anapid species in Baltic amber supports the idea that Eocene European forests may have been a hotspot of evolution for this family of spiders.

A new species of Erotylidae, Cycadophila (s. str.) mumia sp. nov., the first fossil representative of the subfamily Pharaxo-nothinae, is described and illustrated from Eocene Baltic amber. A second closely related specimen is reported but not described as new due to poor preservation in amber. The occurrence of representatives of the Recent cycad-specialized genus in Baltic amber can indirectly indicate the presence of their host plants (Cycadales: Cycadophyta: Cycadopsida) in the Eocene amber forest.

A new species, Dorytomus mikhailovi sp. n., from late Eocene Rovno amber is described and illustrated. The new species is similar to D. groehni Bukejs et Legalov, 2019 from Baltic amber but differs in the shorter rostrum, dorsum covered with denser decumbent hairs and erect to semierect scale-like setae, and smaller body sizes. It is distinguished from D. bukejsi Legalov, 2020 from Baltic amber by the densely punctate pronotum, longer rostrum and wide elytral interstriae. The new species differs from D. vlaskini Legalov et al., 2019 from Rovno amber by the elytral interstriae covered with decumbent hairs and erect to semierect scale-like setae, shorter rostrum and coarsely punctuate pronotum. It is the first named curculionid beetle from the Olevsk amber locality, and the eleventh amber species reported from the Zhitomyr region. The presence of seven species of Dorytomus suggests a rather high diversity of Salicaceae in the late Eocene amber forests of Europe. It corresponds well with other principal Holarctic species in European amber biotas.

Embolemidae is a cosmopolitan but species-poor group of chrysidoid wasps with a scarce fossil record, despite a long evolutionary history since at least the Early Cretaceous. Here, the new species, Ampulicomorpha quesnoyensis sp. nov., is illustrated and described based on a single female found in Early Eocene amber of Oise (France). The new species is compared with the three other known fossil species of the genus, and a key to all fossil species of Ampulicomorpha is provided. This is the third European fossil species of Ampulicomorpha, which suggests that the genus was once well established in Western Europe while it is more widely distributed in the Eastern Palaearctic region today. A list of all fossil and extant Embolemidae of the world, as well as a map of their geographical distribution map, are provided.

Lonchodryinus groehni sp. nov. (Hymenoptera: Chrysidoidea: Dryinidae) is described from Baltic amber. The new species is close to L. balticus Olmi & Guglielmino, 2012, but it can be distinguished for the different OPL/POL ratio and 2r-rs&Rs vein of the fore wing. A key to the fossil species of Lonchodryinus and a comparison with the extant species L. ruficornis (Dalman, 1818) are presented.

A New Species

Species of the megadiverse ground beetle tribe Platynini occur on all continents except Antarctica. It has been long recognized that platynine beetles were preserved in the Eocene Baltic amber. However, thus far only a single Eocene fossil has been described to the species level. In the present paper, a new species of Platynini known only as an amber inclusion fossil is described and imaged using light microscopy and micro X-ray computed tomography. Since this species cannot be assigned to any of the recently described genera, the monotypic genus Praeanchodemus gen. n., with the type species P. punctaticeps sp. n., is erected. There is some evidence from external morphology that Praeanchodemus gen. n. is part of a lineage comprising the recent genera Paranchodemus, Rhadine, and Tanystoma. However, since some synapomorphies were not found, the true relationships of the fossil taxon remain moot.
