Stygnopsidae
The Stygnopsidae are a small family of harvestmen, with almost all species found in Mexico. Name The name of the type genus ''Stygnopsis'' is combined from the genus '' Stygnus'' (Stygnidae) and Ancient Greek ''opsis'', "looks like". (2007): Stygnopsidae. Sørensen, 1932. In: Pinto-da-Rocha ''et al.'' 2007: 232ff Description The body length of these harvestmen ranges from 2.5 (''Karos'') to 7 mm (''Hoplobunus''). Their color ranges from dark brown to black, with much lighter appendages. Cave-dwelling species are pale light brown. Distribution As in other Laniatores, most species have narrow distributions. Almost all species occur in Mexico, with some found in the southern USA (''Hoplobunus''), and Guatemala, El Salvador and Belize (''Paramitraceras''). Relationships Epedanidae could be the sister group to Gonyleptoidea ''sensu lato'' (including the Assamiidae), with the Stygnopsidae the sister group to the rest of Gonyleptoidea. Although they reach into the Nearctic, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stygnidae
The Stygnidae are a family of neotropical harvestmen within the suborder Laniatores. Name The name of the type genus is derived from Ancient Greek ''stygnos'' "diabolic being". (2007): Stygnidae Simon, 1879. In: Pinto-da-Rocha ''et al.'' 2007: 226ff Description Body length ranges from about one to six millimeters. The color ranges from light brown to reddish. Some Heterostygninae have white patches, stripes or spots on the dorsal scutum. Distribution The Heterostygninae are found in the Lesser Antilles, Nomoclastinae are endemic to Colombia, and the Stygninae live from north of the Tropic of Capricorn (central South America). Most species live in the Amazonian rainforest. However, half the species have only been collected once, so distribution of species is poorly known. Relationships The Stygnidae are sister to Cosmetidae and Gonyleptidae, and belong to the same group inside Gonyleptoidea as these and Cranaidae and Manaosbiidae. The Stygnidae are monophyletic.

Assamiidae
Assamiidae are a family of harvestmen with more than 400 described species. It is the third most diverse family of the suborder Laniatores. Name The family name is derived from the Indian province Assam, where the type species of the type genus ('' Assamia westermanni'') was collected. (2007): Assamiidae Sørensen, 1884. In: Pinto-da-Rocha ''et al.'' 2007: 173ff Description These harvestmen range in body length from two to eight millimeters. The length of their legs ranges from four to forty millimeters, though they are usually long. Assamiidae are usually reddish brown to yellow with black mottling and reticulation. Some species have white drawings on the dorsal scutum. Distribution Assamiidae only occur in the Old World, and are completely absent from Madagascar and Europe, with most species found in Africa and southern Asia. Although they are also not found on the Pacific islands, the subfamily Dampetrinae has radiated in Australia, New Guinea, and somewhat in Indonesia. Su ...

Gonyleptoidea
Gonyleptoidea is the most diverse superfamily of the Grassatores. It includes around 2,500 species distributed in the tropics. They are characterized by the simplified male genitalia, with the glans free subapical in the truncus. Gonyleptoidea is the only group of harvestmen to show maternal care of offspring.

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 ...

Carl Friedrich Roewer
Carl Friedrich Roewer (12 October 1881, in Neustrelitz – 17 June 1963) was a German arachnologist. He concentrated on harvestmen, where he described almost a third (2,260) of today's known species, but also almost 700 taxa of spiders and numerous Solifugae. He joined the Nazi Party in the 1930s. From 1933 on, he was the second director of the Übersee-Museum in Bremen, Germany. Under his direction the museum intensified its advocacy of scientific racism. The Senckenbergische Naturforschende Gesellschaft bought his extensive collection (including type material from other arachnologists such as L. Koch, Eugène Simon, Thorell, Philipp Bertkau and Friedrich Dahl) and his private library.Senckenberg forschungsinstitut und naturmuseumArachnology Some of his specimens are also in the Museum für Naturkunde The Natural History Museum (german: Museum für Naturkunde) is a natural history museum located in Berlin, Germany.
