Titanatemnus thomeensis is an endemic pseudoscorpion species of the family Atemnidae that lives on São Tomé Island. It was first described in 1906 by Edvard Ellingsen. [1]
A pseudoscorpion, also known as a false scorpion or book scorpion, is an arachnid belonging to the order Pseudoscorpiones, also known as Pseudoscorpionida or Chelonethida.
The chelicerae are the mouthparts of the Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders. Commonly referred to as "jaws", chelicerae may be shaped as either articulated fangs, or similarly to pincers. Some chelicerae, such as those found on nearly all spiders, are hollow and contain venom glands, and are used to inject venom into prey or a perceived threat. For example, in Pisaurina mira, also known as the nursery web spider, the chelicerae is utilized to snatch the prey once it becomes within reach, facilitating the "sit-and wait ambush predator" behavior. Both pseudoscorpions and harvestmen have structures on their chelicerae that are used for grooming.
Mus mayori is a species of rodent in the genus Mus, the mice. Its common names include Mayor's mouse, highland rat, and spiny mouse. It is endemic to Sri Lanka.
The Empire Cave Pseudoscorpion is a species of arachnid in family Neobisiidae. Fissilicreagris imperialis is endemic to Empire, Dolloff, and IXL caves in Cave Gulch, Santa Cruz County, California. It may occur in one or more of the other caves in Cave Gulch, but it is certainly restricted to this small, isolated karst area. Its habitat is threatened by groups of students who come to the cave to drink and party, and possibly by the clean-up efforts that follow.
Dracochela is an extinct genus of pseudoscorpions.
Joseph Conrad Chamberlin was an American arachnologist who studied mainly pseudoscorpions. A native of Utah, he studied primarily at Stanford University while working most of his career in Oregon for the U.S. Department of Agriculture. Several species are named in his honor.
Lasiochernes cretonatus is a species of pseudoscorpions discovered in the late 1990s in the Souré cave in Crete.
Phagophilia or phagophily is feeding on parasites.
Verrucadithella is a genus of pseudoscorpions in the family Tridenchthoniidae. There are at least three described species in Verrucadithella.
Max Beier was an Austrian arachnologist and entomologist.
Herbert Walter Levi was professor emeritus of zoology and curator of arachnology at the Museum of Comparative Zoology, Harvard University. He was born in Germany, educated there and at Leighton Park School, Reading in England. He then received his higher education at the University of Connecticut and the University of Wisconsin. Levi authored about 150 scientific papers on spiders and on biological conservation. He is the author of the popular Golden Guide Spiders and their Kin, with Lorna Rose Levi and Herbert Spencer Zim.
The British Arachnological Society (BAS) is the UK’s first body devoted exclusively to the study of arachnids. The primary objectives of the Society are to encourage interest in arachnology in people of all ages and to generate, promote and disseminate arachnological knowledge and understanding by all suitable means. In particular, it works to foster co-operation between amateur and professional arachnologists.
Phoresis or phoresy is a non-permanent, commensalistic interaction in which one organism attaches itself to another solely for the purpose of travel. Phoresis has been observed directly in ticks and mites since the 1700s and indirectly in fossils 320 million years old, but is not restricted to arthropods or animals. Plants with seeds that disperse by attaching themselves to animals are also considered to be phoretic.
Chelifer cancroides, the house pseudoscorpion, is a species of pseudoscorpions. It is a cosmopolitan, synanthropic, and harmless species to humans.
Garypus titanius is a species of pseudoscorpions of the family Garypidae. Individuals of this species may be as large as 12 millimetres (0.47 in) long, making it the largest pseudoscorpion in the world. Garypus titanius is endemic to Boatswain Bird Island, off the coast of Ascension Island, in the British overseas territory of Saint Helena, Ascension and Tristan da Cunha.
Atemnidae is a family of pseudoscorpions.
