The Neogoveidae are a family of harvestmen with 27 described species in eight genera. However, eight species of Huitaca, 17 species of Metagovea and 12 species of Neogovea are currently awaiting description.[1]
The name is a combination of Ancient Greek neo "new" and Ogoveidae, a previously described family of Cyphophthalmi that is closely related to Neogoveidae.[2]
Neogoveidae are 1 to 4.5 mm long and eyeless. They often exhibit a solea (modified area with a high concentration of sensory setae) on the first pair of tarsi. Their chelicerae are smooth, with a dorsal crest and ventral process, and can be either short and robust or long and antennuate. They possess laterally projecting ozophores, tarsal claws on the second pair of legs with a row of teeth, tarsal claws on the third and fourth pairs of legs often with small pegs, and an inconspicuous or absent opisthosomal median furrow. The adenostyle is variable, and can be lamelliform, fimbriate, or digitiform. They exhibit both the fusion of coxae 2 and 3, and the fusion of sternites 8 and 9 with tergite 9, the latter of which forms a complete corona analis, which is not present in the genus Metasiro. [2] Exocrine gland pores are located on the sternum in most genera, except Canga and Neogovea, in which they are absent, and Metasiro, in which they are located on the anal plate.[3] The dorsal scutum is heavily granulated, the metatarsi of the legs are ornamented, and the structure of the spermatopositor is highly variable across genera.[2]
Neogoveidae occur in tropical regions between 10° north and 5° south of the equator in both South America and West Africa, with the exception of Metasiro, which is found in southeastern United States.[2]
Current research 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. Currently, the greatest amount of known Neogoveid diversity is known from Colombia, although it is unknown if this reflects greater ecosystem diversity or greater sampling efforts in that country.[1] It is thought that Neogoveidae possesses a considerably large amount of undescribed diversity compared to most other Cyphophthalmi families.[3]
A recent phylogeographical study of Metasiro suggests that, as the genus exists at endpoints of large watersheds, mite harvestmen may be able to disperse by utilizing moving bodies of water.[4]
Molecular studies suggest that the South American species are paraphyletic, with the North American Metasiro forming a sister group to all other Neogoveids, Canga forming a sister group to the African Parogovia, and the rest of the South American genera forming a clade.[5][3] The family is believed to form a sister group relationship with the West African family Ogoveidae. Together, these 2 families make up the superfamily Ogoveoidea, which is the sister group to Troglosironidae. Troglosironidae and Ogoveoidea together make up the infraorder Sternophthalmi, which is well supported as monophyletic by recent phylogenetic analyses.[5]

Recovered by Giribet et al. (2012), with position of Tucanogovea based on original description by Karaman (2013).The species Shearogovea mexasca was formerly included in the genus Neogovea, but has since been removed from both the genus and the family, and its taxonomic position within Cyphophthalmi is uncertain.[6] It has been proposed, however, that the species be re-included within Neogoveidae, and that Metasiro be excluded from the family.[7]

Les Neogoveidae sont une famille d'opilions cyphophthalmes. On connaît une quarantaine d'espèces dans onze genres.
Les espèces de cette famille se rencontrent en Amérique et en Afrique[1].
Selon World Catalogue of Opiliones (18/04/2021)[2] :
Les Neogoveidae sont une famille d'opilions cyphophthalmes. On connaît une quarantaine d'espèces dans onze genres.
Neogoveidae er en gruppe av edderkoppdyr som tilhører ordenen vekjerringer (Opiliones).
Små (kroppslengde 1-5 mm), brunlige vevkjerringer uten øyne. De er middlignende med ganske korte bein med tykke ledd. Kroppen har tydelig segmenterte ryggplater og et klart skille mellom platene på over-og undersiden. Pedipalpene er små og spinkle, chelicerene ganske lange og fremoverrettede.
De fleste kjente artene stammer fra det nordlige Sør-Amerika, men familien er også kjent fra Florida og Vest-Afrika.
Det er foreløpig bare beskrevet 12 arter, men det er ca. 50 arter som er identifisert av eksperter på gruppen.

Распространение Neogoveidae
Neogoveidae (лат.) — семейство паукообразных из подотряда Cyphophthalmi отряда сенокосцев. Включает около 30 видов.
Новый Свет (Северная и Южная Америка), Экваториальная Африка[1].
Мелкие сенокосцы без глаз и с короткими ногами, похожие на клещей. Имеют длину тела от 1 до 4 мм. Как правило, на первой паре лапок имеют подошву (solea) в виде модифицированной области с высокой концентрацией сенсорных щетинок. Хелицеры гладкие, с дорсальным гребнем и вентральным отростком, и могут быть либо короткими и крепкими, либо длинными и усиковидными. Обладают выступающими в боковом направлении озофорами, коготками лапок на второй паре ног с рядом зубцов, коготками лапок на третьей и четвертой парах ног, часто с небольшими шипиками, и незаметной или отсутствующей опистосомальной срединной бороздкой. Дорзальная часть скутума тяжело скульптированная, задние лапки орнаментированные[1][2].
В семейство включают около 30 видов в следующих родах[3][4]:
