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

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.

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.

Hoffeinsoria Herczek & Popov, gen. nov.
No full textGenus Hoffeinsoria Herczek & Popov, gen. nov. Type species: Hoffeinsoria robusta Herczek & Popov sp. nov. Diagnosis. Body elongate oval, not less than 4mm in length. Face (clypeus and genae) in front triangular, narrower than width of head, and eyes strongly prominent. Ocelli distinctly separated and set near posterior margin of head. Tylus elongate. Antennal fossae placed on the frons. Scutellum not enlarged, medium sized. Clavus with divergent sides. Claval Commissure very long, slightly longer than combined length of mesoscutum and scutellum. Comments. This new genus has features clearly distinguished from most known genera of the subfamily Isometopinae. A combination of such characters as: face in front triangular and more narrow than width of head (as in Joceliana from Brazil, Carvalho [1984]), widely separated ocelli setting near posterior margin of the head, placement of antennal fossae on frons (as in Plaumannocoris from Brazil, Carvalho [1947]), and long claval commissure (as in Namaquaropus from South Africa, Akingbohungbe [2004]); all these characteristics also clearly differentiate it from all known genera of tribes Isometopini, Myiommini, and Elektromyiommini (sensu Herczek 1993). Most probably this new genus merits being a separate tribe. Description. Female: Large species, somewhat greater than 4 mm. Entire dorsum very shiny, densely pubescent with semi-erect black hairs arising from hardly visible punctures. Head with the large glabrous eyes, from above sub-rectangular to semilunar in outline; ocelli moderately protuberant, setting near the posterior margin of head, separated by about 4.5 width of each, set somewhat near inner side of eyes; eyes very large, touching anterior margin of pronotum and width of eye 1.5 x less than vertex width; clypeus quite long and narrow, reaching half of high head; antennal bases (fovea antennalis) set on distinctly above lower level of eyes; antennae slender, dark brown, moderately short, almost twice as short as length; II segment longest; rostrum reaching second abdominal segment. Pronotum distinctly transverse, ca. 2 twice as wide as long, disc moderately convex, shiny, almost impunctate, and covered with semi-erect black hair, collar not developed, calli strongly flattened and hardly distinguished (mainly visible as strongly glabrous patches), posterior margin straight and bordered by long dark hairs; mesoscutum almost 2.5 shorter than scutellum length, distinctly inclined backwards. Hemelytra wholly impunctate, especially corium; cuneus distinctly separate from corium, membrane with two cells, one of which very small, pale-brown hyaline; membranea strongly declivous, distinctly crumpled, mainly pale yellow and dark brown in periphery; claval commissure very long, slightly longer than combined length of mesoscutum and scutellum and almost 1.5 times longer than scutellum. Legs short, hind femora significantly not reaching apex of abdomen; tarsi 2 -segmented, 1 st segment almost 1.5 x shorter than 2 nd one; claws with subapical tooth. Venter generally black; prosternum, mesepimeron and metasternum black; coxae partly black, or somewhat pale yellow; femora and tibiae partly pale yellow, dorsal side of tibiae and tarsi dark brown. Abdomen very robust, segments 6–9 gradually enlarged. Etymology. This genus is named after our friends and colleagues Christel and Hans Werner Hoffeins (Hamburg, Germany), who donated these amber inclusions. Composition. One species: Hoffeinsoria robusta sp. nov.Published as part of Herczek, Aleksander & Popov, Yuri A., 2012, A new peculiar isometopine genus (Hemiptera: Heteroptera: Miridae) from the Eocene Baltic amber, pp. 64-68 in Zootaxa 3196 on page 65, DOI: 10.5281/zenodo.28013

The holotype of Andrena skorikovi is conspecific with the lectotype of A. firuzaensis and as the first revisers we choose A. skorikovi as the valid name. Remark. Male unknown (according to Osytshnjuk et al. 2005: 142). Osytshnjuk et al. (2005: 141) indicated that one syntype specimen as the ‘holotype’, but Popov (1940) did not directly indicate a single specimen and two specimens from the type series are deposited in the ZISP. According to the Recommendation 74A of the Code (ICZN, 1999) we here designated the ‘holotype’ specimen as lectotype. Distribution.

On the robust Popov criterion for interval Lur’e systems
No full textIn this note, the classical Popov criterion is generalized to include problems with parametric uncertainty as well as nonlinear sector bounded perturbations. The parametric dependence is modeled by an interval plant description. A robust Popov criterion is obtained for a plant-controller configuration. Stronger extremal results are obtained for a special class of controllers. An example illustrating the numerical implementation of these results is presented. © 1993 IEE
European policies for social inclusion of Roma : Catch 22?
No full textThe 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
