Guides
Briggsus
Briggsus is a genus of armored harvestmen (Opiliones) in the family Cladonychiidae. The genus contains five described species, all originally described by Briggs in 1971 and later transferred to this genus by Özdikmen & Demir in 2008. Species in this genus are restricted to coastal forests of the Pacific Northwest.
Cryptomaster
daddy longlegs
Cryptomaster is a genus of armoured harvestmen (Opiliones) in the family Cryptomastridae, established in 1969 and containing two described species: C. leviathan and C. behemoth. Both species are endemic to the mountains of southwest Oregon and represent short-range endemic arachnids. The genus remained understudied for decades until 2016, when expanded distributional records of C. leviathan prompted discovery of the second species. These harvestmen belong to the suborder Laniatores, characterized by relatively short legs and cryptic habits in forest floor habitats.
Speleonychia
Speleonychia is a genus of armoured harvestmen (Opiliones: Laniatores) in the family Cladonychiidae, established by Briggs in 1974. The genus contains at least one described species, S. sengeri, which is endemic to Washington state in the northwestern United States. As a member of the Travunioidea superfamily, it belongs to a group of small, often cryptic harvestmen associated with moist microhabitats. The genus name suggests a cave-associated or subterranean lifestyle, though specific ecological details remain poorly documented.
Zuma tioga
Zuma tioga is an armoured harvestman (order Opiliones) described by Briggs in 1971. It belongs to the family Paranonychidae within the infraorder Insidiatores. The species is known from North America, though specific locality details beyond this broad region are not well documented. Like other members of its family, it is a small, soil-dwelling arachnid with a heavily sclerotized body.
