Third contribution on Rovno amber silken fungus beetles: a new Eocene species of Cryptophagus (Coleoptera, Clavicornia, Cryptophagidae)  [cached]
Georgy Lyubarskiy,Evgeny Perkovsky
ZooKeys , 2011, DOI: 10.3897/zookeys.130.1321
Abstract: Cryptophagus alexagrestis Lyubarsky & Perkovsky sp.n. is described based on a fossil inclusion in Late Eocene Rovno amber (Ukraine). The new species is similar to the extant Cryptophagus skalitzkyi Reitter and C. dilutus Reitter, differing from the latter bya very transverse, short and dilated 10th antennal segment, and from the former by the very elongate segments of the flagellum.
First Record of Mites of the Family Stigmaeidae (Acari, Raphignathoidea) from Rovno Amber with Description of a New Species of the Genus Mediolata
N. N. Kuznetsov, A. A. Khaustov, E. E. Perkovsky
Vestnik Zoologii , 2010, DOI: 10.2478/v10058-010-0037-3
Abstract: A new species, Mediolata eocenica Kuznetsov, Khaustov et Perkovsky, sp. n., is described from the Late Eocene Rovno amber. It is the first fossil record of Stigmaeidae.
A new genus and species of Dictyopharidae (Homoptera) from Rovno and Baltic amber based on nymphs  [cached]
Alexandr Emeljanov,Dmitry Shcherbakov
ZooKeys , 2011, DOI: 10.3897/zookeys.130.1775
Abstract: Alicodoxa rasnitsyni gen. et sp. n. (Dictyopharinae: Orthopagini) is described based on a nymph from Rovno amber; it also occurs in Baltic amber. A small additional wax plate dorsal to the large wax plate of abdominal tergites VI–VIII is first reported in this and other genera of Dictyopharidae. A lectotype is designated for Pseudophana reticulata Germar & Berendt, 1856 transferred to Protepiptera (Achilidae): Protepiptera reticulata (Germar & Berendt, 1856), comb. n.
A new species of the genus Disogmus F rster (Hymenoptera, Proctotrupoidea, Proctotrupidae) from the Eocene Rovno amber  [cached]
Victor Kolyada,Evgeny Perkovsky
ZooKeys , 2011, DOI: 10.3897/zookeys.130.1560
Abstract: Disogmus rasnitsyni Kolyada & Perkovsky, sp. n. is described from a fossil inclusion of Late Eocene amber (Ukraine). The new species is most similar to D. basalis (Thomson, 1857), in particular, in the shape of the tyloids and the general shortening of the segments of antennae, but distinctly differs from it and the other species of the genus bytyloids on flagellar segments 2–4 compared to 3–6 and 4–7 in other species.
The First Eocene Species of the Genus Cryptophagus (Coleoptera, Clavicornia, Cryptophagidae)
G. Yu. Lyubarsky, E. E. Perkovsky
Vestnik Zoologii , 2012, DOI: 10.2478/v10058-012-0007-z
Abstract: Based on a fossil specimen from the Late Eocene Rovno amber (Ukraine), Cryptophagus harenus Lyubarsky et Perkovsky, sp. n., an Eocene species of this genus is described. The new species is similar to the extant desert species Cryptophagus desertus Lyubarsky and C. recticollis Solsky, differing by the large callosity occupying 1/4 length of lateral margin of pronotum.
Insect frass in Baltic amber  [PDF]
Matti Nuorteva,Kari A. Kinnunen
Bulletin of the Geological Society of Finland , 2008,
Abstract: Inclusions of wood debris loosened from pine-like trees are abundant in Baltic amber of Eocene and Oligocene age. The possibilities to find insect frass and excrement among wood debris are outlined and some examples are given. Comparison with the frass and excrement produced by present-day insects provide a possibility to identify insects even though their fossils are lacking. This information can be used to characterize former forest environments. Amber forests may have also covered Southern Finland, and this possibility is discussed. Furthermore, the presence of wood debris may be utilized to recognize amber fakes, which is important for both gem trade and paleontology. It is proposed that databases and identification keys of frass and excrement should be constructed.
On the diversity of pseudoscorpions in Macedonia: Neobisium maksimtodorovici n. sp. Neobisiidae, Pseudoscorpiones
?ur?i? Bo?idar P.,Dimitrijevi? Rajko N.,Mihajlova Branislava D.
Archives of Biological Sciences , 2002, DOI: 10.2298/abs0204105c
Abstract: A new troglobitic species, Neobisium maksimtodorovici n. sp. (Neobisiidae Pseudoscorpiones), inhabiting the Momi ek Cave, v. Belica, nr. Makedonski Brod, Macedonia, has been discovered and its diagnosis presented. In support of some earlier findings, this novelty points to the pronounced biodiversity of the area studied.
A check list of the pseudoscorpions of South Africa (Arachnida: Pseudoscorpiones)  [cached]
A.S. Dippenaar-Schoeman,M.S. Harvey
Koedoe : African Protected Area Conservation and Science , 2000, DOI: 10.4102/koedoe.v43i2.201
Abstract: A check list of the Pseudoscorpiones of the class Arachnida of South Africa is presented. A total of 135 species and 10 subspecies of pseudoscorpions are known from South Africa, represented by seven superfamilies, 15 families and 65 genera. This represents about 4.4 of the world fauna. Of the 135 species, 97 species (73 ) are known only from South Africa, 33 species have a wider distribution pattern throughout the Afrotropical Region and three are cosmopolitan. This study forms part of the South African National Survey of Arachnida (SANSA).
The first fossil cyphophthalmid harvestman from Baltic amber  [PDF]
Dunlop, Jason A.,Mitov, Plamen G.
Arachnologische Mitteilungen , 2011, DOI: 10.5431/aramit4006
Abstract: The first fossil cyphophthalmid harvestman (Opiliones: Cyphophthalmi) from Palaeogene (Eocene) Baltic amber is described. This is only the third fossil example of this basal harvestman lineage; the others being from the probably slightly younger Bitterfeld amber and the much older, early Cretaceous, Myanmar (Burmese) amber. Although incomplete and lacking most of the appendages, the new Baltic amber fossil can be identified as a female. The somatic characters preserved, especially spiracle morphology and the coxo-genital region, allow it to be assigned with some confidence to the extant genus Siro Latreille, 1796 (Sironidae). This fossil is formally described here as Siro balticus sp. nov. It resembles modern North American Siro species more than modern European ones, and can be distinguished principally on its relatively large size and the outline form of the body.
Fossil harvestmen (Arachnida, Opiliones) from Bitterfeld amber
Jason Dunlop,Plamen Mitov
ZooKeys , 2009, DOI: 10.3897/zookeys.16.224
Abstract: Fossil harvestmen (Arachnida: Opiliones: Dyspnoi and Eupnoi) are described from Bitterfeld amber, Sachsen-Anhalt, Germany deposited in the Museum für Naturkunde, Berlin. The exact age of this amber has been in dispute, but recent work suggests it is youngest Palaeogene (Oligocene: Chattian). Histricostoma tuberculatum (Koch & Berendt, 1854), Caddo dentipalpus (Koch & Berendt, 1854), Dicranopalpus ramiger (Koch & Berendt, 1854) and Leiobunum longipes Menge, 1854 – all of which are also known from Eocene Baltic amber – are reported from Bitterfeld amber for the first time. They support the idea that both ambers sampled a similar terrestrial arthropod fauna: irrespective of any difference in age. Mitostoma gruberi sp. n. and Amilenus deltshevi sp. n. are described as new. One fossil is, in our opinion, morphologically indistinguishable from the extant species Lacinius erinaceus Star ga, 1966 from the Caucuses, and is tentatively assigned to this taxon. The Bitterfeld material thus includes the first fossil record of the extant genera Amilenus Martens, 1969 and Lacinius Thorell, 1876 respectively.
