Pseudoscorpions of the World has been developed to provide some basic information on the world of pseudoscorpions and, in particular, provide information about the various pseudoscorpion families, valid names of genera and species, and a comprehensive list of the scientific literature that deal with pseudoscorpions. This website should be cited as: Harvey, M.S. (2011) Some species are blind, but even those with sight are not able to see well. They use their claws like antennae, feeling and touching their surroundings to find their way around. Pseudoscorpions can make their own silk, but they do not spin webs or use it to catch prey like a spider would. Instead, they build cocoons to shelter in during cold winters Pseudoscorpions are neither dangerous, nor destructive; they eat many small arthropods, including caterpillars, flies, ants, beetle larvae, and booklice. Most of the more than 2000 described species inhabit the tropics, where they occupy animal nests, crevices of bark, and leaf litter. Several dozens species are present in Pennsylvania. The pseudoscorpion species commonly encountered by Pennsylvanians is cosmopolitan—the house pseudoscorpion, Chelifer cancroides (L.) You may go through your entire life and never see a pseudoscorpion, although there are over 3,000 species of them worldwide. In North America, there are over 200 species, but they usually make their homes under tree bark and stones, in bird nests, and in cracks and crevices Two new pseudoscorpion species, Geogarypus muchmorei sp. nov. from India and G. klarae sp. nov. from Papua New Guinea, are described and illustrated. New data for G. sagittatus Beier, 1965 are reported and a supplementary description is given, based on a new specimen
Pseudoscorpions, usually found in leaf litter, humus, behind bark, and under rocks, are a distinct order within the class Arachnida (arachnids). They occasionally are found in homes, where they arrive having hitched rides on houseflies and other flying insects. Some species live with mammals and birds, feeding on their lice and other parasites Pseudoscorpions (also known as False Scorpions or book scorpions) are not actually scorpions at all but are a type of arachnid. They belong to the same class of animals as spiders - the arachnida; and are known as pseudo-scorpions as they look exactly like scorpions but without the stinging tail. Fast Facts While examining the pseudoscorpion specimens collected from leaf litter in Wuzhi Mountain, we found sixteen specimens of Chernetidae lacking the angulate posterior margin of the carapace found in Goniochernetinae and also lacking the T-shaped spermathecae found in Lamprochernetinae
The pseudoscorpion genus Verrucachernes Chamberlin, 1947 is widely distributed in the Old World tropics, with three named Australasian and West Pacific species and two from Africa Tuberochernes cohni was named in memory of entomologist Ted Cohn, who passed away in 2013 at age 82. Cohn discovered a new genus of cricket from the same cave where the new pseudoscorpion species.
The largest pseudoscorpion species is only about a centimeter long, and most of the 3000+ species are only a few millimeters long. Unlike true scorpions, they lack a tail with venomous stinger, and instead they have venom glands connected to their pincers. But don't fear; the venom is only a cause for concern if you are a tiny creature like a. Some species live in special association with other arthropods, such as large beetles or ant colonies. About 2000 species of pseudoscorpions are known worldwide. The abdomen of the pseudoscorpion is oval and has a wide junction with the rectangular carapace, the shell-like covering of the head and upper part of the body A new pseudoscorpion species in Amblyolpium (Pseudoscorpiones Karlsruhe, September 2016 Arachnologische Mitteilungen / Arachnology Letters 52: 1-3 A new pseudoscorpion species in Amblyolpium (Pseudoscorpiones: Garypinidae) from a house in Kermanshah Province, Iran Mahrad Nassirkhani, Reza Vafai Shoushtari & Mahtab Rahmat Abadi doi: 10.5431/aramit5201 Abstract Scorpion-Spider Bug Hybrid: New Pseudoscorpion Species, Parobisium Yosemite, Documented For First Time By James Cokendolpher (VIDEO) Zoe Triska. The Parobisium yosemite, commonly known as the Yosemite cave pseudoscorpion, has quite the fearsome appearance. However, coming in at a little under half an inch, the arachnid is not capable of doing.
Pseudoscorpions are common, but rarely seen. They are harmless, small (1/16 to 1/8 inch long), tick-shaped critters that have a large pair of pincers, but lack the long tail and stinger of a true scorpion. Pseudoscorpions are beneficial, because they feed on carpet beetles, ants, mites, small flies and other critters in the home A new and endangered species of the pseudoscorpion genus Lagynochthonius from a cave in Vietnam, with notes on chelal morphology and the composition of the Tyrannochthoniini (Arachnida, Chelonethi, Chthoniidae) Zootaxa, 1627 (2007), pp. 53-68.

Although data on the abundance of pseudoscorpion species in the humid tropics are lacking, preliminary observations suggest that the number of species is greater in the Mediterranean area than in tropical rain forests. Speciation in pseudoscorpions has not been studied in great detail. New taxa are constantly being described This species is found in two dry, relatively small, limestone caves that have some infiltration of groundwater. Distribution. The Tooth Cave pseudoscorpion is endemic to Tooth, Amber, and possibly McDonald Caves in Travis and Williamson Counties near Austin, Texas. The pseudoscorpion is not known to exist elsewhere Pseudoscorpion There are over 200 species of pseudoscorpions in North America.

Commensalism is a relationship between two organisms in which one organism benefits, and one is unaffected. This can be contrasted with other types of symbiosis, such as mutualism and parasitism.The supposed difference between commensalism and other types of symbiosis is that in commensalism, the second party or host remains unaffected Its habitat gets covered by the tide twice a day and, obviously, the pseudoscorpion survives immersion in sea water for a few hours everyday..
