Diversity
5 genera, 12 species

The Neogoveidae are a family of harvestmen with twelve described species in five genera. However, at least seven species of Huitaca, 17 species of Metagovea and twelve species of Neogovea are currently awaiting description[1].

Description

Neogoveidae are 1 to almost 5 mm long and eyeless.[2]

Distribution

They occur between 10° north and 5° south of the equator in South America and Africa, with the exception of Metasiro, which is found in Florida[2]. Metasiro is most closely related to species from West Africa. Florida was part of Western Africa near what is today Senegal prior to the formation of Pangea. When North America parted from West Africa about 170 million years ago, it took Florida and its harvestmen with it.[3]

Current research[4] suggests that the diversity of neotropical Neogovidae is much higher than currently known, as new species were found at virtually every place where samples were taken.

Huitaca species have been found in Colombia at elevations ranging from 300 m to more than 3,000 m. Neogovea is found from Trinidad, the lowlands of the Amazonas and Orinoco basins, but also at higher elevations in the Colombian Andes and Venezuela. Metagovea species live mostly along the Andes, but a few are found in the Amazonas basin.[4]

Relationships

Molecular studies suggest that the American species are monophyletic, forming a sister group to the African species, and that those two are themselves related to the North American Metasiro.[2]

Name

The name is a combination of Ancient Greek neo "new" and Ogoveidae.
