Eresus Cinnaberinus
''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. Both ''Eresus cinnaberinus'' and ''Eresus niger'' are now regarded as '' nomina dubia''. Distributions * ''E. kollari'' has the widest distribution of the three species, occurring from Spain and Portugal to Novosibirsk in Russia. * ''E. moravicus'' occurs in the Pannonian region, the Balkan Peninsula and parts of the Austrian Alps The Central Eastern Alps (german: Zentralalpen or Zentrale Ostalpe ...

Eresus
''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''. Description They resemble both jumping spiders and the spiders in the Palpimanidae, as their bodies look similar, and are as well rather velvety. Males of this genus have a red abdomen, with black spotting, usually taking the form of 4 black spots. While the rest of the body is usually black, with some reddish areas or white areas. Females of this genus are duly colored usually being a grey, brown or black color. Some species having some yellow coloration, thought they are still significantly duller then the males. Identification Males of this genus can usually be distinguished by their unique abdominal pattern. Which in the lateral areas has two pai ...

Eresus Kollari
''Eresus kollari'', the ladybird spider, is a spider species in the family Eresidae. It was first described by Walckenaer in 1802, though it was misidentified. It was later correctly described by Rossi in 1846. It is one of the three species into which ''Eresus cinnaberinus'' or ''Eresus niger'' has been divided. It is thought to be endangered. Description Their body as most Velvet spider, velvet spiders, resemble somewhat those in the jumping spider family. The males have a contrasting color, having a black and red coloration, while the females are completely black. The opisthosoma looks velvety, as their common name would imply. Colonies In colonies, they burrow up to 10 cm in depth. Which is usually covered in a funnel web. Females may carry lens shape egg sack containing up to 100 eggs. Which she’ll carry to a sunny place. The juveniles will stay in the females burrow and feed on her after she dies. They usually form small colonies with up to a couple dozen spider ...

Eresus Sandaliatus
''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. ''E. sandaliatus'' is one of the three species into which ''Eresus cinnaberinus'' or ''Eresus niger'' has been divided. Description Male ''E. sandaliatus'' are generally (a little bit smaller than other species of the ''E. cinnaberinus'' complex) and characterized by a bright orange back featuring four large and two small ebony spots. White hairs are never present on the back, and legs always lack red hairs. In contrast, the females are and jet-black. Habits Males enter the adult stage in early September, but overwinter in their webs and search for females only in May or June of the next year. Otherwise, this species is very similar to other species of ''E. cinnaberinus'' complex. After the 35-80 eggs hatch, the spiderlings receive a liquid from the mouth of th ...

Eresus Moravicus
''Eresus moravicus'' is a spider species in the family Eresidae found in Austria, Hungary, Czechia, Serbia, Slovakia and Albania. Being found mainly in rocky steppes. It is named after the eastern part of the Czech Republic, Moravia, which is where the type species was found. ''E. moravicus'' is one of the three species into which ''Eresus cinnaberinus'' or ''Eresus niger'' has been divided. Description This is the largest ''Eresus'' species found in Central Europe, males are black and red in color. the first two legs are black, with the last two being red. The opisthosoma is red with the carapace being black. While the females are mostly black, except with orange hairs on the from part of the prosoma. Identification ''E. moravicus'' can be distinguished from the other two species by the totally red hind legs in males and the orange hairs on prosoma in females, among other features. To identify them from the Mediterranean species which also share this trait, it is speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nomina Dubia
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pannonian Basin
The Pannonian Basin, or Carpathian Basin, is a large Sedimentary basin, basin situated in south-east Central Europe. The Geomorphology, geomorphological term Pannonian Plain is more widely used for roughly the same region though with a somewhat different sense, with only the Upland and lowland, lowlands, the plain that remained when the Pliocene Epoch ''Pannonian Sea'' dried out. It is a geomorphological subsystem of the Alpide belt, Alps-Himalaya system, specifically a sediment-filled back-arc basin which divergent boundary, spread apart during the Miocene. The plain or basin is diagonally bisected by the Transdanubian Mountains, separating the larger Great Hungarian Plain (including the Eastern Slovak Lowland) from the Little Hungarian Plain. It forms a topographically discrete unit set in the European landscape, surrounded by imposing geographic boundaries—the Carpathian Mountains and the Alps. The Rivers Danube and Tisza divide the basin roughly in half. It extends rough ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balkan Peninsula
The Balkans ( ), also known as the Balkan Peninsula, is a geographical area in southeastern Europe with various geographical and historical definitions. The region takes its name from the Balkan Mountains that stretch throughout the whole of Bulgaria. The Balkan Peninsula is bordered by the Adriatic Sea in the northwest, the Ionian Sea in the southwest, the Aegean Sea in the south, the Turkish Straits in the east, and the Black Sea in the northeast. The northern border of the peninsula is variously defined. The highest point of the Balkans is Mount Musala, , in the Rila mountain range, Bulgaria. The concept of the Balkan Peninsula was created by the German geographer August Zeune in 1808, who mistakenly considered the Balkan Mountains the dominant mountain system of Southeast Europe spanning from the Adriatic Sea to the Black Sea. The term ''Balkan Peninsula'' was a synonym for Rumelia in the 19th century, the European provinces of the Ottoman Empire. It had a geop ...

Austrian Alps
The Central Eastern Alps (german: Zentralalpen or Zentrale Ostalpen), also referred to as Austrian Central Alps (german: Österreichische Zentralalpen) 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. The term "Central Alps" is very common in the Geography of Austria as one of the seven major landscape regions of the country. "Central Eastern Alps" is usually used in connection with the Alpine Club classification of the Eastern Alps (''Alpenvereinseinteilung'', AVE). The Central Alps form the eastern part of the Alpine divide, its central chain of mountains, as well as those ranges that extend or accompany it to the north and south. The highest mountain in the Austrian Central Alps is Grossglockner at . Location The Central Alps have the highest peaks of the Eastern Alps, and are located between the Northern Limestone Alps and the ...

Eresidae
Velvet spiders (family Eresidae) are a small group (about 130 species in 9 genera) of spiders almost entirely limited to the Old World, with exception of a few species known from Brazil. In Europe some are commonly called the ladybird spiders Description This family can sometimes be confused with the jumping spiders, or those in the Palpimanidae family. These spiders are usually black or brown in color, thought they can also have brighter colors as pictured. As their common name implies they can look quite smooth and velvety. They usually live in silken tubes under objects, or underground, but the genus ''Stegodyphus,'' builds silken nests. Identification They can be distinguished from most species except the Penestomidae by their semi rectangular carapace and clypeal hood. Thought the can be distinguished from Penestomidae by the eye arrangement, straight anterior eye row and strongly recurved posterior eye row, with the median eyes close together. Social Behavior ...
