Eresus cinnaberinus

Last updated

Eresus cinnaberinus and Eresus niger are names formerly used for a group of spiders in the genus Eresus now divided into three species, E. kollari , E. sandaliatus and E. moravicus . The three species differ in size, colour pattern, shape of prosoma and copulatory organs, and habitat, with no morphologically intermediate forms. As eastern and western E. kollari are genetically different, with the eastern form likely a hybrid between "pure" E. kollari and E. moravicus, it is possible that later revisions will partition it into additional species. [1]

Both Eresus cinnaberinus and Eresus niger are now regarded as nomina dubia . [1] [2]

Alps Major mountain range system in Central Europe

The Alps are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately 750 mi (1,210 km) across eight Alpine countries : France, Switzerland, Monaco, Italy, Liechtenstein, Austria, Germany, and Slovenia.

Geography of Switzerland Geographical features of Switzerland

The geography of Switzerland encompasses the geographical features of Switzerland, a mountainous and landlocked country located in Western and Central Europe. Switzerland's natural landscape is marked by its numerous lakes and mountains. It is surrounded by 5 countries: Austria and Liechtenstein to the east, France to the west, Italy to the south and Germany to the north. Switzerland has a maximum north–south length of 220 kilometres (140 mi) and an east–west length of about 350 kilometres (220 mi).

Carpathian Mountains Mountain range in Central and Eastern Europe

The Carpathian Mountains or Carpathians are a range of mountains forming an arc across Central and Eastern Europe. Roughly 1,500 km (930 mi) long, it is the third-longest European mountain range after the Urals at 2,500 km (1,600 mi) and the Scandinavian Mountains at 1,700 km (1,100 mi). The range stretches from the far eastern Czech Republic (3%) and Austria (1%) in the northwest through Slovakia (17%), Poland (10%), Hungary (4%), Ukraine (10%), Romania (50%) to Serbia (5%) in the south. The highest range within the Carpathians is known as the Tatra mountains in Slovakia and Poland, where the highest peaks exceed 2,600 m (8,500 ft). The second-highest range is the Southern Carpathians in Romania, where the highest peaks range between 2,500 m (8,200 ft) and 2,550 m (8,370 ft).

Geography of Austria Overview of the geography of Austria

Austria is a predominantly mountainous country in Central Europe, approximately between Germany, Italy and Hungary. It has a total area of 83,871 square kilometres (32,383 sq mi), about 2.031706 times the size of Switzerland.

Geology of the Alps The formation and structure of the European Alps

The Alps form part of a Cenozoic orogenic belt of mountain chains, called the Alpide belt, that stretches through southern Europe and Asia from the Atlantic all the way to the Himalayas. This belt of mountain chains was formed during the Alpine orogeny. A gap in these mountain chains in central Europe separates the Alps from the Carpathians to the east. Orogeny took place continuously and tectonic subsidence has produced the gaps in between.

Tethys Ocean Mesozoic ocean between Gondwana and Laurasia

The Tethys Ocean, also called the Tethys Sea or the Neo-Tethys, was an ocean during much of the Mesozoic Era and early Cenozoic Era, located between the ancient continents of Gondwana and Laurasia, before the opening of the Indian and Atlantic oceans during the Cretaceous Period.

Spotted nutcracker Species of bird

The spotted nutcracker, Eurasian nutcracker, or just nutcracker, is a passerine bird slightly larger than the Eurasian jay. It has a much larger bill and a slimmer looking head without any crest. The feathering over its body is predominantly chocolate brown with distinct white spots and streaks. The wings and upper tail are virtually black with a greenish-blue gloss. It is one of three species of nutcracker. The Kashmir nutcracker, was formerly considered a subspecies of the spotted. The other member of the genus, Clark's nutcracker, occurs in western North America.

Central Eastern Alps Portion of the Eastern Alps mountain range through Austria and parts of surrounding countries

The Central Eastern Alps, also referred to as Austrian Central Alps or just Central Alps, comprise the main chain of the Eastern Alps in Austria and the adjacent regions of Switzerland, Liechtenstein, Italy and Slovenia. South them is the Southern Limestone Alps.

Mediterranean Basin Region of lands around the Mediterranean Sea that have a Mediterranean climate

In biogeography, the Mediterranean Basin is the region of lands around the Mediterranean Sea that have mostly a Mediterranean climate, with mild to cool, rainy winters and warm to hot, dry summers, which supports characteristic Mediterranean forests, woodlands, and scrub vegetation.

Geography of the Alps Description of the landforms of the Alps mountain range

The Alps cover a large area. This article describes the delimitation of the Alps as a whole and of subdivisions of the range, follows the course of the main chain of the Alps and discusses the lakes and glaciers found in the region.

Eastern Alps Eastern part of the Alps mountain range

Eastern Alps is the name given to the eastern half of the Alps, usually defined as the area east of a line from Lake Constance and the Alpine Rhine valley up to the Splügen Pass at the Alpine divide and down the Liro River to Lake Como in the south. The peaks and mountain passes are lower than the Western Alps, while the range itself is broader and less arched.

<i>Eresus sandaliatus</i> Species of spider

Eresus sandaliatus is a species of spider found primarily in northern and central Europe. Like other species of the genus Eresus, it is commonly called ladybird spider because of the coloration of the male.

<i>Eresus</i> Genus of spiders

Eresus, also called ladybird spiders, is a genus of velvet spiders that was first described by Charles Athanase Walckenaer in 1805. Members of the genus formerly called Eresus cinnaberinus or Eresus niger are now placed in one of three species: Eresus kollari, Eresus sandaliatus and Eresus moravicus.

Austroalpine nappes Geological formation in the European Alps

The Austroalpine nappes are a geological nappe stack in the European Alps. The Alps contain three such stacks, of which the Austroalpine nappes are structurally on top of the other two. The name Austroalpine means Southern Alpine, because these nappes crop out mainly in the Eastern Alps.

<i>Eresus kollari</i> Species of spider

Eresus kollari, the ladybird spider, is a spider species in the family Eresidae.

<i>Eresus moravicus</i> Species of spider

Eresus moravicus is a spider species in the family Eresidae found in Austria, Hungary, Czechia, Serbia, Slovakia and Albania.

Geology of Germany Overview of the geology of Germany

The geology of Germany is heavily influenced by several phases of orogeny in the Paleozoic and the Cenozoic, by sedimentation in shelf seas and epicontinental seas and on plains in the Permian and Mesozoic as well as by the Quaternary glaciations.

The geology of Austria consists of Precambrian rocks and minerals together with younger marine sedimentary rocks uplifted by the Alpine orogeny.
