Six species of harvestman (Arachnida: Opiliones) are documented from the Eocene Rovno amber in Ukraine. From the suborder Eupnoi we record Caddo dentipalpus (C. L. Koch & Berendt, 1854) (Caddidae), Amilenus deltshevi Dunlop & Mitov, 2009 (Phalangiidae) and Dicranopalpus ramiger (C. L. Koch & Berendt, 1854) (family incertae sedis). To these we add a new phalangiid, Metaphalangium martensi sp. n., which is the oldest representative of the Recent genus Metaphalangium Roewer, 1911 and new genus for the amber fauna. From Dyspnoi we record Sabacon claviger (Menge, 1854) (Sabaconidae) and propose Parahistricostoma gen. n. (Nemastomatidae), to accommodate Nemastoma tuberculatum C. L. Koch & Berendt, 1854, yielding Parahistricostoma tuberculatum (C. L. Koch & Berendt, 1854) comb. n. The Rovno harvestman fauna is briefly compared to both Baltic and Bitterfeld amber. The fossil species, C. dentipalpus, A. deltshevi, D. ramiger and P. tuberculatum occur in all three ambers, and S. claviger is found in Baltic and Rovno amber. The only genus and species unique to Rovno amber is thus our new taxon M. martensi. The composition of the Rovno opilionid fauna is discussed in the context of late Eocene palaeoenvironment and ecological preferences and the fossils are compared to the distribution of extant harvestman taxa. The oribatid mite Platyliodes ensigerus Sellnick, 1919 (Acari: Neoliodidae) is reported from Rovno amber for the first time.

Abstract Gall midges are reported for the first time in Late Eocene Rovno amber from the Olevsk, Zhitomir Region. This is the second amber locality to yield gall midges in the Zhitomir Region, after Gulyanka. Rovnoholoneurus gen. n. and two new species, Rovnoholoneurus davidi sp. n. and R. miyae sp. n. are described. Bryocrypta laqueata Fedotova, 2005 is transferred to the genus Rovnoholoneurus, and Rovnoholoneurus laqueatus (Fedotova, 2005), comb. n. is established. A key to the species of Rovnoholoneurus is provided.

The present article represents the first part of a review of fossil heterostigmatic mites collected from late Eocene Rovno amber. Here, mites of the families Tarsocheylidae, Dolichocybidae, and Acarophenacidae are described, with Tarsocheylidae and Dolichocybidae recorded for the first time from amber. A new genus and four new species are described, namely, Hoplocheylus similis sp. nov. (Tarsocheylidae), Dolichocybe elongata sp. nov. (Dolichocybidae), Proadactylidium fossibilis gen. and sp. nov. and Paradactylidium sineunguis sp. nov. (Acarophenacidae). The extant species Acarophenax lacunatus Cross and Krantz, 1964 and A. assanovi Livshitz and Mitrofanov, 1974 are transferred to the new genus Proadactylidium. A revised key to the genera of Acarophenacidae is presented. The homologies of prodorsal setae in Acarophenacidae are reconsidered and reviewed.

Abstract ‘Paraphiomys’ simonsi is a phiomorph rodent from the early Oligocene of Egypt (~29–30 Mya) that has historically been aligned with much younger (< ~20 Mya) Miocene species of the genera Paraphiomys and Neosciuromys. Here, we use Bayesian tip-dating analysis of a 109-character morphological matrix containing 57 living and extinct ctenohystricans to test these proposed placements for ‘Paraphiomys’ simonsi. Our analyses provide support for the exclusion of ‘Paraphiomys’ simonsi from both Paraphiomys and Neosciuromys and justify the establishment of a new genus (Monamys gen. nov.) for this stem thryonomyoid. These analyses also indicate that the divergence of the extant dassie rat Petromus from the extant cane rat Thryonomys (i.e. origin of crown Thryonomyoidea) occurred ~23.7 Mya, close to the Oligocene–Miocene boundary and in close agreement with recent molecular estimates for this split. Miocene Neosciuromys, Paraulacodus, Protohummus and the type species of Paraphiomys are identified as stem thryonomyids, whereas the Namibian species Apodecter stromeri, Tufamys woodi, ‘Paraphiomys’ australis and ‘Paraphiomys’ roessneri are identified for the first time as stem petromurids, raising the possibility of a long period of endemic petromurid evolution in south-west Africa. Comparison of molecular divergence estimates with our optimal tip-dated topology suggests that stem bathyergoids are most likely to have arisen from late Eocene and early Oligocene ‘phiomyids’.

AbstractSystematic analysis shows that the Southern Hemisphere bivalve genus Retrotapes includes the Antarctic species R. antarcticus, R. newtoni, and R. robustus and recognizes for the first time the presence of Katelysia represented by K. florentinoi. Two new genera were erected in this study: Marciachlys new genus to include M. inflata new combination, and Adelfia new genus, which includes A. austrolissa new combination and A. omega new species from the Eocene of Antarctica, and the late Eocene Chilean A. arenosa new combination. Eurhomalea carlosi was synonymized with K. florentinoi; Cyclorismina marwicki with R. antarcticus; Gomphina iheringi was considered an indeterminate species; and Cockburnia lunulifera was excluded from the Tapetinae. These systematic assignments are supported by a phylogenetic analysis, which recognizes an Austral clade of Tapetinae, comprising all the genera mentioned above, along with Marcia, Paleomarcia, Atamarcia, and Protapes.UUID: http://zoobank.org/a8c91a9f-99ec-4235-8416-d398771a3eb2

Glesoconomorphus ekaterinaesp. nov.

A key to species of the fossil mycterid genus Glesoconomorphus Alekseev, Pollock & Bukejs, 2019 is presented. The systematic position of Glesoconomorphus within Eurypinae J. Thomson, 1860 is briefly discussed. The oldest finding of phoretic Winterschmidtiidae Oudemans, 1923 mites, found on the type specimen of the new beetle species, is reported.

Species of Bibionidae from Baltic amber are reevaluated based on newly discovered material, and a key to the species is given. Bibio succineussp. nov. is described based on one male specimen, this is the first Bibio named from Baltic amber. The males of Hesperinus electrus Skartveit, 2009 and Penthetria montanaregis Skartveit, 2009 are redescribed. A single, autoclave treated specimen of Penthetria sp. is described but not formally named. Plecia tenuicornis Skartveit, 2009 is found to be a synonym of Plecia hoffeinsorum Skartveit, 2009, this species is recorded for the first time from Rovno amber, and both sexes of the species redescribed. Additional specimens of Plecia clavifemur Skartveit, 2009 and Dilophus crassicornis Skartveit, 2009 are described. Two female specimens probably belonging to the species discussed as Dilophus sp. by Skartveit (2009) are described, but not formally named.

A new extinct monotypic genus of the false darkling beetles, Madelinia gedanoposita gen. et sp. nov., is described and illustrated based on an inclusion in Baltic amber. The new taxon from a northern European Eocene forest is compared with the morphologically similar extant beetles as well as fossil melandryid beetles found in Baltic amber. The specimen establishes that the tribe Hypulini dates back to at least the Eocene and represents the first fossil genus of the group described. The composition of the tribe is discussed, and its present-day geographic distribution is mapped.

A new species, Formica ribbeckei Radchenko & Perkovsky, sp. nov., is described based on four workers from late Eocene Rovno amber (Ukraine). It most resembles F. flori Mayr, 1868 but differs from the latter mainly by the 5-segmented maxillary palps with the preapical segment subequal in length to the apical one, and by the shorter first funicular segment. Fossil F. luteola Presl, 1822, F. trigona Presl, 1822, F. macrognatha Presl, 1822 and F. quadrata Holl, 1829 are considered incertae sedis in Formicidae. Thus, ten valid Formica Linnaeus, 1758 species (including F. ribbeckei) are known now from late Eocene European ambers. The diversity of Formica in the early and middle Eocene deposits of Eurasia and North America is considered. It is assumed that the genus Formica most likely arose in the early Eocene.
