Cynorta is a genus from the subfamily Cynortinae. [1] The genus was first described by Carl Ludwig Koch. [2]
The type species of Cynorta is Cynorta conspersa . [3]
The initial description of the genus was based on occurrences in Brazil, Costa Rica, Cuba, Ecuador, French Guiana, and Suriname. [3] Overall, the genus is poorly defined, and currently includes multiple species from different regions without support for shared ancestry. [2]
The Opiliones are an order of arachnids colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. As of April 2017, 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.
Cosmetidae is a family of harvestmen in the suborder Laniatores. With over 700 species, it is one of the largest families in Opiliones. They are endemic of the New World with a Nearctic-Neotropical distribution where a large fraction of the diversity of Opiliones are represented by this single family. Cosmetidae have the northern extent of their range into the USA, where a small number species occur in the southern states. However, the family is especially diverse in Mexico, Central America and northern South America; especially the Andean realms. Their range also extends further south into Argentina and southern Brazil, but they are absent in Chile. Cosmetidae are prevalent in Amazonian region, but only relatively few also occur in Brazilian Atlantic Forest. Several species are also found in the Caribbean.
The Phalangiidae are a family of harvestmen with about 380 known species. The best known is Phalangium opilio. Dicranopalpus ramosus is an invasive species in Europe.
Rilaena triangularis is a species of the harvestman family Phalangiidae. It is sometimes considered to be in the genus Paraplatybunus, in the subfamily Platybuninae.
The Cladonychiidae are a small family of harvestman with about 33 described species, within the suborder Laniatores.
Globipes is a genus of harvestmen in the family Globipedidae from North America with three described species. Two are found on the western coast of the USA.
Cladolasma, is a genus of harvestmen belonging to the family Nemastomatidae. The genus is monotypic containing a single species Cladolasma parvulum. They are endemic to Japan, with records in Ehime and Tokushima Prefectures. The genus was described by Seisho Suzuki, with the type species Cladolasma parvulum Suzuki, 1963, subsequently revised to Dendrolasma parvulum in Suzuki (1974), but later restored as a valid genus.
