Guasiniidae
The Guasiniidae are a family of harvestman with three described species from South America. It is, together with the Fissiphalliidae and the Ogoveidae, one of the least diverse harvestman families. The family is probably closely related to the Zalmoxidae and Fissiphalliidae. All described species in this family are completely eyeless (anophthalmic). González-Sponga found the two first species inside bark under litter, ''G. persephone'' was also found inside soil, in an inundation-forest of black-water (igapó) at Tarumã-Mirim, near the mouth of Rio Negro, 20 km upstream from Manaus. The region is flooded for almost half a year. Current research suggests that the two described genera should be merged into one.

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 ...

Zalmoxidae
The Zalmoxidae are a family of harvestmen within the suborder Laniatores. Name Zalmoxis is the name of a Thracian god. Description Zalmoxidae are small Laniatores of dark brown to dark yellow color with varied darker mottling. Some small edaphic species are pale yellowish. Males of varies species bear sexually dimorphic and embellished armature, particularly in the fourth walking leg. Distribution Members of this family are distributed in the tropics on opposite sides of the Pacific Ocean, as well as Melanesian archipelagoes and some Micronesian islands. Zalmoxidae do not occur in mainland Africa or Madagascar. In the Neotropics, most species occur from Costa Rica to Brazil, with a center of diversity in Venezuela. In the Indo-Pacific, many species in New Guinea. Two species are found in the Seychelles and Mauritius. Systematics For a list of currently described species, see the List of Zalmoxidae species.

Venezuela
Venezuela (; ), officially the Bolivarian Republic of Venezuela ( es, link=no, República Bolivariana de Venezuela), is a country on the northern coast of South America, consisting of a continental landmass and many islands and islets in the Caribbean Sea.

Rio Negro (Amazon)
The Rio Negro ( pt, Rio Negro, br ; es, Río Negro} "''Black River''"), or Guainía as it is known in its upper part, is the largest left tributary of the Amazon River (accounting for about 14% of the water in the Amazon basin), the largest blackwater river in the world, and one of the world's ten largest rivers by average discharge. Geography Upper course The source of the Rio Negro lies in Colombia, in the Department of Guainía where the river is known as the ''Guainía River''. The young river generally flows in an east-northeasterly direction through the Puinawai National Reserve, passing several small indigenous settlements on its way, such as Cuarinuma, Brujas, Santa Rosa and Tabaquén. After roughly 400 km the river starts forming the border between Colombia's Department of Guainía and Venezuela's Amazonas State. After passing the Colombian community of Tonina and Macanal the river turns Southwest. Maroa is the first Venezuelan town the river passes. 1 ...
