A revision of the genus Mycetobia Meigen, 1818 from the Eocene is presented. Redescription of Mycetobia connexa Meunier, 1899 known from the Baltic amber is given and documented by photographs and drawings. Five new species of Mycetobia from Eocene resins are described, four from Baltic amber: Mycetobia christelae sp. nov., Mycetobia hansi sp. nov., Mycetobia silvia sp. nov., Mycetobia szwedoi sp. nov. and one from the Ukrainian amber: Mycetobia perkovskyi sp. nov. Key to the species of Mycetobia known from the Eocene is provided.

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 fossil genus of net-winged beetles, Protolopheros gen. n., and a new species, Protolopheros hoffeinsorum sp. n., are described from the Baltic amber. The new taxon is placed in Erotini, next to Lopheros Leconte, 1881. The extant Pseudaplatopterus (Eropterus) Green, 1951, comb. n. is lowered in rank and placed as a subgenus of the fossil Pseudaplatopterus Kleine, 1940. The extant Kolibaceum (Laterialis) Kazantsev, 1990, comb. n. is lowered in rank and placed as a subgenus of the fossil Kolibaceum Winkler, 1987.

The Baltic amber has proven to be an incredible resource for the environmental and faunistic diversity of the Eocene and this is also evident from the vast amount of Cantharidae species (soldier beetles) described as inclusions in this resin and Fossil-Lagerstätte. The present work contributes to highlighting both this trend and the variety of forms in particular for the genus Malthodes Kiesenwetter, 1852 with four new species described and with the addition of a new species of Cacomorphocerus Schaufuss, 1892 with two specimens included in the same amber piece. The new forms, described and illustrated here, are: Cacomorphocerus obstinatus sp. nov., Malthodes giannii sp. nov., Malthodes immortalis sp. nov., Malthodes marialuisae sp. nov., and Malthodes unimol sp. nov.

Abstract. A new specimen of Lacinius Thorell, 1876; (Opiliones: Phalangiidae) from Eocene Baltic amber is described. We interpret it as conspecific with a slightly younger record from the German Bitterfeld amber, originally referred to as the extant species L. erinaceus Staręga, 1966. Our new specimen reveals pedipalpal apophyses on both the patella and the tibia, features which we can now confirm in the Bitterfeld fossil too. This unique character combination for the genus justifies a new, extinct species: Lacinius bizleyi sp. nov. The Baltic amber inclusion dates to ca. 44–49 Ma, and is thus the oldest putative example of Lacinius in the fossil record. It is a further example of an arachnid species shared between Baltic and Bitterfeld amber.

Atomaria gedanicola Lyubarsky et Perkovsky, sp. n., a new cryptophagid species from Baltic amber is described. The new species is the first recorded Eocene Atomariinae. The new species is similar to A. fuscipes Gyllenhal. It differs from the latter in having pronotum flat, posterior angles of pronotum obtuse, and antenna short. The record of A. gedanicola syninclused with Ceratopogon biting midge supports the Late Eocene age of the Baltic amber, for the Holarctic affinities of both taxa are incompatible with the paratropical climate characteristic of the Mid-European Middle Eocene.
