Nemastomatidae
The Nemastomatidae are a family of harvestmen with about 170 described species in 16 recent genera. Several fossil species and genera are known. Unlike some related currently recognized families, the Nemastomatidae are monophyletic. (2007): Nemastomatidae. Simon, 1872. In: Pinto-da-Rocha et al. 2007: 148ff Description Members of the Nemastomatidae range in body length from about one to almost six millimeters. Their chelicerae are of normal proportions, but the pedipalps are very elongated and thin in some groups. Leg length is likewise variable. Distribution The subfamily Ortholasmatinae (ten species in two genera) occur on both sides of the Pacific Ocean: in western North America from Mexico to British Columbia and eastern Asia (Japan and northern Thailand. The other subfamily, Nemastomatinae, occur all over Europe up to Iceland and the Caucasus, in the Atlas Mountains of North Africa, from Anatolia to northern Iran, with a few species found outside this region, in Central Asi ...

Dyspnoi
Dyspnoi is a suborder of harvestmen, currently comprising 43 extant genera and 356 extant species, although more species are expected to be described in the future. The eight families are currently grouped into three superfamilies: the Acropsopilionoidea, Ischyropsalidioidea, and Troguloidea. Distribution The Dyspnoi are one of the most biogeographically conserved higher groups of harvestmen. With the exception of Acropsopilioidea, none occur in the Southern Hemisphere, and most families are restricted along temperate regions. The only exceptions are some Ortholasmatinae (Nemastomatidae) inhabiting the tropics on high mountains in Mexico (''Ortholasma bolivari'') and northern Thailand ('' Dendrolasma angka'').

Harvestmen
The Opiliones (formerly Phalangida) are an order of arachnids colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. , over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014. Representatives of each extant suborder can be found on all continents except Antarctica. Well-preserved fossils have been found in the 400-million-year-old Rhynie cherts of Scotland, and 305-million-year-old rocks in France. These fossils look surprisingly modern, indicating that their basic body shape developed very early on, and, at least in some taxa, has changed little since that time. Their phylogenetic position within the Arachnida is disputed; their closest relatives may be the mites (Acari) or the Novogenuata (the Scorpiones, Pseudoscorpiones, and Solifugae). Altho ...

Dicranolasma
The Dicranolasmatidae are a family of harvestmen with 16 described species in a single genus, ''Dicranolasma''. Description Species of ''Dicranolasma'' range in body length from three to 6.4 mm. Most parts of the body are encrusted with soil particles. The anterior region features a large headlike "hood" with the eyes in center, which consists of two curved processes. The chelicerae and pedipalps are both hidden under the hood in adults and about half as long as the body. The legs are short. Immature forms are quite different from adults. The immature form of ''D. opilionoides'' was even described as a different genus (''Amopaum''). The hood develops only gradually, so in young ''Dicranolasma'' the relatively longer pedipalps are carried outside the hood. (2007): Dicranolasmatidae Simon, 1879. In: Pinto-da-Rocha ''et al.'' 2007: 142ff Distribution Dicranolasmatidae occur mainly in the Mediterranean region northward to the southern Alps, the Carpathians, eastward to the Cauca ...

Trogulidae
Trogulidae is a family of harvestmen with 5 genera and 57 extant species and one fossil species. Members of this species have short legs and live in soil. They have dirt attached to their bodies, to escape predators. Their body length ranges from 2 to 22 mm. The body is in most genera somewhat flattened and leathery. Adults have a small hood, which hides their short chelicerae and pedipalps. (2007): Trogulidae Sundevall, 1833. In: Pinto-da-Rocha et al. 2007: 157ff Distribution Members of this family occur in western and southern Europe, up to western North Africa and the Levant, the Caucasus and northern Iran. ''Trogulus tricarinatus'', a predator of terrestrial snails, has been introduced to eastern North America. Name The derivation of the name of the type genus, ''Trogulus'', is not fully understood. The describer Latreille wrote that he named it because it looks like a monkshood. Perrier (1929) however derived the name from Ancient Greek ''trogein'' "gnawing", because ...

Caucasus
The Caucasus () or Caucasia (), is a region between the Black Sea and the Caspian Sea, mainly comprising Armenia, Azerbaijan, Georgia, and parts of Southern Russia. The Caucasus Mountains, including the Greater Caucasus range, have historically been considered as a natural barrier between Eastern Europe and Western Asia. Mount Elbrus in Russia, Europe's highest mountain, is situated in the Western Caucasus. On the southern side, the Lesser Caucasus includes the Javakheti Plateau and the Armenian highlands, part of which is in Turkey. The Caucasus is divided into the North Caucasus and South Caucasus, although the Western Caucasus also exists as a distinct geographic space within the North Caucasus. The Greater Caucasus mountain range in the north is mostly shared by Russia and Georgia as well as the northernmost parts of Azerbaijan. The Lesser Caucasus mountain range in the south is occupied by several independent states, mostly by Armenia, Azerbaijan, and Georgia, but also ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Himalayas
The Himalayas, or Himalaya (; ; ), is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the planet's highest peaks, including the very highest, Mount Everest. Over 100 peaks exceeding in elevation lie in the Himalayas. By contrast, the highest peak outside Asia (Aconcagua, in the Andes) is tall. The Himalayas abut or cross five countries: Bhutan, India, Nepal, China, and Pakistan. The sovereignty of the range in the Kashmir region is disputed among India, Pakistan, and China. The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain. Some of the world's major rivers, the Indus, the Ganges, and the Tsangpo–Brahmaputra, rise in the vicinity of the Himalayas, and their combined drainage basin is home to some 600 million people; 53 million people live in the Himalayas. The Himalayas have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
