| Hapalotremus major (Chamberlin, 1916) [1] | |
Hapalotremus major is a species of tarantula, in the subfamily Theraphosinae. It is native to Peru. [1]
Ralph Vary Chamberlin originally described this species as Hemirrhagus major, but it was later transferred to Hapalotremus by Fernando Pérez-Miles & Arturo Locht. [1]
Hapalotremus major differs from all other species of Hapalotremus by a thinner and more curved embolus, and also its size, which is proportionately large (29 mm). [2]
Ralph Vary Chamberlin was an American biologist, ethnographer, and historian from Salt Lake City, Utah. He was a faculty member of the University of Utah for over 25 years, where he helped establish the School of Medicine and served as its first dean, and later became head of the zoology department. He also taught at Brigham Young University and the University of Pennsylvania, and worked for over a decade at the Museum of Comparative Zoology at Harvard University, where he described species from around the world.
Anicius is a monotypic genus of Mexican jumping spiders containing the single species, Anicius dolius. It was first described by Ralph Vary Chamberlin in 1925, and is only found in Mexico.
Vaine Wilton Ivie was an American arachnologist, who described hundreds of new species and many new genera of spiders, both under his own name and in collaboration with Ralph Vary Chamberlin. He was employed by the American Museum of Natural History in New York. He also was a supporter of the Technocracy movement.
The Theraphosinae are a large subfamily of Mygalomorphae spiders in the family Theraphosidae found in the Neotropical realm.
Anethoporus is a genus of spirostreptid millipedes native to northern South America, where they range from Peru to the islands of Trinidad and Tobago. The genus and type species, A. clarki, was established by Ralph V. Chamberlin in 1918.
Sonatsa is a genus of marine, mud-dwelling polychaete worms containing the sole species Sonatsa meridionalis. S. meridionalis was described in 1919 by Ralph Vary Chamberlin from a single specimen collected by the research ship USS Albatross during a 1904–05 survey of the southeast Pacific Ocean. The type specimen was collected between Peru and the Galapagos Islands, from muddy sediment at a depth of around 4 km. The name Sonatsa derives from the Goshute words soma, meaning "many", and natsani, meaning "hook", while the specific name meridionalis is Latin for "southern".
Nopsides is a monotypic genus of North American araneomorph spiders in the family Caponiidae, containing the single species, Nopsides ceralbonus.

They are active during the night, hiding under large stones of Mexico's deserts and xeric shrublands during the day.
Tarsonops is a genus of araneomorph spiders in the family Caponiidae, first described by Ralph Vary Chamberlin in 1924.
