Triaenonychidae
The Triaenonychidae are a family of harvestmen with about 120 genera and more than 440 described species. Description Most Triaenonychidae are from three to five millimeters long, although some species from South Africa can be only long. Some species in the subfamily Adaeinae are almost long. Legs are almost always short, measuring . The armed pedipalps are large, and much stronger than the legs. Distribution Triaenonychidae are found in North and South America, Japan and Korea, Australia and New Zealand, and Madagascar. Relationships The Triaenonychidae should probably split into at least two families. The genera from the Australian region are considered Triaenonychidae ''sensu stricto'', and may include the strange Synthetonychiidae; the northern species should be grouped with Travuniidae. Name The name of the type genus ''Triaenonyx'' is combined from Ancient Greek (', "trident, fish spear") and (', "claw"). Genera The following genera are included in the family:Joel ...

Fumontana Deprehendor
''Fumontana'' is a genus of harvestman that occurs in the United States (North Carolina and Tennessee) with one described species, ''F. deprehendor''. Biogeography While members of the family Triaenochychidae are well represented in western North America, Chile, South Africa, New Zealand, Australia, Korea, and Japan, ''F. deprehendor'' is the first species found in the eastern United States. The Appalachian millipede genus '' Choctella'' shows a similar distribution, suggesting they both stem from the same Gondwanan fauna. Certain aspects of its anatomy (such as position and form of the eye tubercle, and the male genitalia) make it likely that it is most closely related to genera in other parts of the world, such as '' Monomontia'' in South Africa or '' Hendea'' in New Zealand. ''F. deprehendor'' is thus likely an ancient relict, suggesting a wide distribution of the family before the current distribution of continents. Habitat It was first discovered in forest litter of Green ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Opiliones
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). Althou ...

Synthetonychiidae
The Synthetonychiidae are a small family of harvestman with a handful of species in a single genus. They are endemic to New Zealand. Description Species in this family are between one and two millimeters long, with legs up to almost six mm. (2007): Synthetonychiidae. Forster, 1954. In: Pinto-da-Rocha ''et al.'' 2007: 239ff Distribution All described species occur only on New Zealand. Relationships Synthetonychiidae seem to be closely related to the Triaenonychidae from the Australian region. Name The name of the type genus is combined from 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 peri ... ''synthetos'' "compounded" and ''onychion'', the diminutive of ''onyx'' "claw".

Arachnid
Arachnida () is a class of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons. Almost all adult arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word (''aráchnē'', 'spider'), from the myth of the hubristic human weaver Arachne, who was turned into a spider. Almost all extant arachnids are terrestrial, living mainly on land. However, some inhabit freshwater environments and, with the exception of the pelagic zone, marine environments as well. They comprise over 100,000 named species, of which 47,000 are species of spiders. Morphology Almost all adult arachnids have eight legs, unlike adult inse ...

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system.
