Holozoster ovalis is a species of harvestmen endemic to Mahe Island of Seychelles. [2]
The Opiliones are an order of arachnids, colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. As of July 2024, 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.
Opilio is a genus of harvestmen with 35 known species.
Dyspnoi is a suborder of harvestmen, currently comprising 43 extant genera and 356 extant species, although more species are expected to be described in the future. The eight families are currently grouped into three superfamilies: the Acropsopilionoidea, Ischyropsalidioidea, and Troguloidea.
Cyphophthalmi is a suborder of harvestmen, colloquially known as mite harvestmen. Cyphophthalmi comprises 36 genera, and more than two hundred described species. The six families are currently grouped into three infraorders: the Boreophthalmi, Scopulophthalmi, and Sternophthalmi.
The Cranaidae are a family of neotropical harvestmen within the suborder Laniatores.
Podoctidae is a family of the harvestman infraorder Grassatores with about 130 described species.
Yania is a genus of harvestmen from South America. Yania flavolimbata is the only species in the monotypic genus Yania. It was first described by Roewer, 1914.
Tetrophthalmi is an extinct suborder of Opiliones that had both median and lateral eyes. First described in 2014, it is known from two extinct species. Phylogenetic analysis suggests that this eye arrangement is the ancestral condition for harvestmen, placing Tetrophthalmi and Cyphophthalmi in a basal position within Opiliones.
Ibalonius inscriptus is a species of harvestmen from the family Podoctidae. The species is endemic to Mahe Island and Silhouette Island of the Seychelles. The species has a synonymous name Ibalonius bimaculatus which as of 2024, remains listed as such on the IUCN database, despite being considered the same species by Hirst (1911), as followed in other catalogs and listings .. Similarly, another form described as Paribalonius bimaculatus duplex Roewer 1923 was also treated as a synonym by Staręga (1992).
Samoa is a genus of harvestmen. It consists of three species:
Travunioidea is a superfamily of armoured harvestmen in the order Opiliones. There are 4 families and around 75 described species in Travunioidea.
Siro is a genus of mite harvestmen in the family Sironidae with 7 described species. All are found in Europe.
Vonones is a genus of armoured harvestmen in the family Cosmetidae. There are at least two described species in Vonones.
Paranonychus brunneus is a species of armoured harvestman in the family Paranonychidae. It is found in eastern North America, ranging from Oregon through Washington, British Colombia, and Alaska.
Paranonychus is a genus of harvestman in the family Paranonychidae. There are three described species in Paranonychus.. The Japanese species Paranonychus fuscus was originally described in its own genus as Mutsunonychus fuscus Suzuki 1976, but considered its own species and part of Paranonychus in later studies.
Neosiro exilis is a species of mite harvestman in the family Sironidae. It is found in North America.
Izunonychus is a monotypic genus of harvestman in the family Paranonychidae. There is one described species in Izunonychus, I. ohruii, endemic to Japan.
Nippononychus is a genus of harvestman in the family Paranonychidae. There is one described species in Nippononychus, N. japonicus, endemic to Japan.
Metanippononychus is a genus of harvestman in the family Paranonychidae. There are at least four described species in Metanippononychus.
Parasiro is a genus of harvestmen belonging to the family Parasironidae with one described species. It is found in Southwestern Europe.
