Leptosaldinea cobbeni Popov & Heiss, 2016, sp.nov.
No full textLeptosaldinea cobbeni sp.nov. (Figs. 1–12) Type material. Holotype: macropterous female preserved in a piece of Burmese amber which is embedded in a block of transparent artificial resin for better conservation, provided with following red label: “ Holotype / Leptosaldinea gen.nov. / cobbeni sp. nov. / des. Heiss & Popov, 2015 ”. The holotype is deposited in the collection of the second author (EH) at the Tiroler Landesmuseum, Innsbruck, Austria. Body convex; left eye and pronotal margin damaged, surface of median part of pronotum, scutellum and clavus missing and probably eaten by scavengers, their remains depressed and not clearly discernible; legs and antennae complete with long spines and setae. Description. As given in the generic diagnosis and description. Measurements (mm). Length 2.75; width of hemelytra 1.35; length of antennae 1.95, ratio length of antennae / width of head = 2.78; length of antennal segments I:II:III:IV = 0.15: 0.25: 0.75: 0.80; length of rostral segments I:II:III:IV =?: 0.15: 0.20: 0.20; length of pronotum at middle 0.4, anterior width 0.5, posterior width 0.85; scutellum length 0.37; legs: femur:tibia:tarsus including claws: fore leg 0.875: 0.8: 0.4; middle leg 0.875: 0.875: 0.375; hind leg 1.0: 1.40: 0.5. Drawings might show slight differences to given measurements because of partly obscured visibility of structures. Etymology. Named after the eminent Dutch hemipterologist René Cobben, who proposed the subfamily Leptosaldinae for the first discovered leptosaldine species, Leptosalda chiapensis.Published as part of Popov, Yuri A. & Heiss, Ernst, 2016, A remarkable fossil leptosaldine bug from Mid-Cretaceous Burmese amber (Hemiptera: Heteroptera: Leptopodomorpha: Leptopodidae), pp. 233-238 in Zootaxa 4137 (2) on page 237, DOI: 10.11646/zootaxa.4137.2.5, http://zenodo.org/record/25743

Insect remains (Hemiptera : Belostomatidae; Coleoptera) from the Upper Jurassic ("Kimmeridgian") of Nettelstedt (Wiehengebirge, NW Germany)
No full textFrom sediments of the Upper Jurassic ("Kimmeridgian" of the northwest German lithostratigraphical terminology) near Nettelstedt (Wiehengebirge) two insect wings are described. One of them represents a new genus and species of the Belostomatidae (Hemiptera: Heteroptera): Nettelstedtia breitkreutzi. It is similar to Odrowazicoris POPOV, 1996 and Tarsabedus POPOV et al., 1994, both from Lower Jurassic strata of Europe, but differs mainly by the very narrow subcostal area (embolium). The second specimen is a coleopteran elytra which cannot be determined in detail
European policies for social inclusion of Roma : Catch 22?
Get PDFThe article analyzes contemporary political discourses with regard to social inclusion of Roma on the basis of comparison with achievements and failures in the previous historical period of the communist rule in Eastern Europe. It argues that since the vast majority of the European Roma had lived in the past and continue living nowadays in the countries of Eastern Europe, no successful policy for their inclusion is possible without taking into account the experiences and outcomes of the actions for Roma integration in the socialist period. The experience from the times of socialism shows that successful policies are possible only in an appropriate socio-political context and only if accomplished within the mainstream approach. Against this background, the article scrutinizes the European Policies for Social Inclusion of Roma, and explains why they present a Catch 22 situation: There is a vicious cycle of problems which need to be solved; the solution requires a special policy for inclusion, however this policy stigmatizes Roma and sets them even more apart from the rest of society. Thus the vicious cycle of problems expands. The main point of the article is to propose an explanation of this failure of democracy and liberalism, which could constitute a useful lesson for the future.Peer reviewe

No full textHispanocader Golub, Popov et Arillo, n. gen. Type species: Hispanocader lisae Golub, Popov et Arillo, n. sp. Included species: monotypic. Diagnosis. Relation of antennal segment lengths: I III> IV. Head strongly elongate, with one pair of frontal short spines. Bucculae short and low, settled in anterior quarter of the lower head surface only. Hemelytral venation comparatively rich. Areolae of hemelytra are small.Published as part of Golub, V. B., Popov, Yu. A. & Arillo, A., 2012, Hispanocaderidae n. fam.

Perturbative Yang–Mills theory without Faddeev–Popov ghost fields
No full textA modified Faddeev–Popov path integral density for the quantization of Yang–Mills theory in the Feynman gauge is discussed, where contributions of the Faddeev–Popov ghost fields are replaced by multi-point gauge field interactions. An explicit calculation to O(g2) shows the equivalence of the usual Faddeev–Popov scheme and its modified version.© 2018 The Author
Grimaldinia pronotalis Popov & Heiss, 2014, sp. n.
No full textGrimaldinia pronotalis sp. n. (Figs. 1–2, photo 1–2) Holotype. Submacropterous specimen, sex not determined, in a half-moon shaped piece of Burmese Amber (20 x 4 x 7mm) embedded in a block of transparent resin; left forewing damaged by an oval cut out probably caused by scavengers; specimen is ventrally attached to a strip of lizard skin, thus ventral side of specimen is not visible, lateral view partly obscured by amber impurities; membraneous hind wing of the left forewing is laterally roundly exposed and overlapping the right fore wing, its surface showing dense microsculpture and longitudinal venation. Deposited as BUB-LEP- 1 in the collection of the second author. Description. As given in the generic diagnosis and description. Coloration of dorsal and ventral side (as far as visible) uniformly black. Measurements. Length 3.0mm; head width / length 45 / 24, anterior width between eyes 6; pronotum length at middle / width 11 / 27, length laterally 14; scutellum length / width 33 / 33; length of eye 10, diameter 4. Etymology. Refers to the conspicuous configuration of the pronotum.Published as part of Popov, Yuri A. & Heiss, Ernst, 2014, Grimaldinia pronotalis n. gen., n. sp. from Mid-Cretaceous Burmese Amber (Hemiptera: Heteroptera, Leptopodidae, Leptosaldinae), pp. 444-450 in Zootaxa 3878 (5) on page 449, DOI: 10.11646/zootaxa.3878.5.2, http://zenodo.org/record/22909

Dhofaria Popov 1985
No full textGenus: Dhofaria Popov, 1985 Popov 1985: 73 (as nomen novum). Type species: Omania splendens Popov, 1981. Remarks. Popov (1981: 114) established the genus Omania for its only species O. splendens Popov, 1981. Because of the junior homonymy [of Omania Horvarth, 1915 (Hemiptera)] Popov (1985: 73) proposed a new generic name for this taxon, Dhofaria Popov, 1985. Koçak & Kemal (2008: 3) unaware of this proposed a new name for Omania Popov which was interestingly the same name, Dhofaria Koçak & Kemal, 2008, that was synonymized by Koçak & Kemal (2009: 4).Published as part of Ünal, Mustafa, 2016, Pamphagidae (Orthoptera: Acridoidea) from the Palaearctic Region: taxonomy, classification, keys to genera and a review of the tribe Nocarodeini I.
