A New Species

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 paper contains a review of coleopteran genera known from Baltic, Bitterfeld and Rovno amber localities. Altogether 420 genera (191 extinct and 229 extant) from 78 families are listed from these three Lagerstätten (as of 7 March 2017). The listed beetles were analyzed zoogeographically and distributional maps for 72 genera were compiled. One-quarter (56) of the genera that have survived since the Eocene have cosmopolitan ranges at present; 35 extant genera have been extripated from the Palaearctic since the Eocene. Approximately 40% of beetle genera from the middle-upper Eocene European ambers can be encountered in the wild in present-day Europe, while 5 of these genera are supposed to be European relict endemics originating in Fennosarmatia. The general similarity of the Baltic amber (s.l.) beetle assemblage to modern south Palaearctic fauna is the strongest, the Nearctic elements are more numerous in the middle-upper Eocene European ambers than the Oriental taxa. The simplified Mutual Climatic Range (MCR) method was used for palaeoclimate reconstruction based on fossil beetles. The coleopteran assemblage of Baltic amber is interpreted as indicative of warm temperate, humid, equable climate with reduced thermal seasonality [annual average temperatures range from +10–20˚C; mean of the coldest month temperatures around +10˚C; mean of the hottest month temperature around +20–24˚C; annual precipitation around 750–1500 mm]. The primary importance of high humidity for existence of the Eocene biota is pointed out.

Abstract Dipteran insects constitute 51 % among arthropods of the Rovno Amber. There are 99 species and 23 genera of the Diptera described from the Rovno Amber; however, to date only 32 species are shared with the Baltic Amber fauna, including two species that are treated in this paper. Triphleba schulmanae Brown, 2003 (Phoridae), originally described from the Baltic Amber, is recorded in the Rovno Amber for the first time and its amended description is supplied. Genus Prosphyracephala Hennig, 1965 (Diopsidae), earlier known from the Baltic and Saxonian ambers, the Upper Eocene of Ruby River (Montana, USA) and the Lower Oligocene of Céreste (France), is recorded in the Rovno Amber for the first time. Prosphyracephala aff. succini (Loew, 1873) is the first diopsid record from Ukraine. A second specimen of Prosphyracephala kerneggeri Kotrba, 2009 is found in the Baltic amber; the complete wing venation is described for the first time for this species. Vast majority of the Old World Diopsidae are strictly thermophilous. In fact, all of them but the five species of brevicornis group of Sphyracephala Say (three Palearctic and two Nearctic ones) frequent tropic and the warmest subtropic areas, however the thermophilous Diopsidae are known in the New World neither in past nor in contemporary fauna.

A New Species

A new species of the genus Palaeopoecilostola Meunier, 1899 (Diptera: Limoniidae) from the Baltic amber (Upper Eocene) is described. The cladistic analysis of the species included in this genus is provided. The distributional pattern of the Palaeopoecilostola species is discussed. Palaeopoecilostola as numerous and remarkable representative of Limoniidae, can be treated as the marker genus of the Baltic amber in broad sense (including Bitterfeld and Ukrainian ambers). Anepsiomyia atterraneus Nazarov, 1994 is resurrected from synonymy with Palaepoecilostola speciosa Meunier, 1906. Ryta berestiana Nazarov, 1994 appears a junior synonym of Palaepoecilostola speciosa Meunier, 1906.

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.

Eocene Amber

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.

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.
