''Hexura rothi'' is a species of spider in the family Mecicobothriidae. It was described by Gertsch & Platnick, 1979 — USA. It has two spinnerets.

Mecicobothriidae
Dwarf tarantulas, also known as sheet funnel-web spiders are a type of spider from the family Mecicobothriidae. Dwarf tarantulas are one of several families of the suborder Mygalomorphae; this larger group also includes the true tarantulas. Description Dwarf tarantulas, as the name indicates, appear very similar to tarantulas, but are physically much smaller. Many specimens are smaller than 1 cm in length, and the largest in the family are seldom larger than 2 cm. The spiders, like all Mygalomorphae, have downward pointing fangs; dwarf tarantulas also have long spinnerets. Genera There is currently only 1 recognized genus in this family: ''Mecicobothrium'' Holmberg, 1882 * '' Mecicobothrium baccai'' Lucas et al., 2006 — Brazil * ''Mecicobothrium thorelli'' Holmberg, 1882 — Argentina, Uruguay Genera moved to other families include: *''Hexura'' Simon, 1884 → Antrodiaetidae *'' Hexurella'' Gertsch & Platnick, 1979 → Hexurellidae *''Megahexura'' Kaston, 1972 → ...

Klamath Mountains
The Klamath Mountains are a rugged and lightly populated mountain range in northwestern California and southwestern Oregon in the western United States. As a mountain system within both the greater Pacific Coast Ranges and the California Coast Ranges, the Klamath Mountains have a varied geology, with substantial areas of serpentinite and marble, and a climate characterized by moderately cold winters with very heavy snowfall and warm, very dry summers with limited rainfall, especially in the south. As a consequence of the geology and soil types, the mountains harbor several endemic or near-endemic trees, forming one of the largest collections of conifers in the world. The mountains are also home to a diverse array of fish and animal species, including black bears, large cats, owls, eagles, and several species of Pacific salmon. Millions of acres in the mountains are managed by the United States Forest Service. The northernmost and largest sub-range of the Klamath Mountains are t ...

Del Norte, California
Smith River (Tolowa: ''Kaa-nvsh'') is a town and census-designated place in Del Norte County, California, located near the Oregon border. Smith River is the headquarters of the Tolowa Dee-ni' Nation, a federally recognized tribe of Tolowa people. As of the 2020 census, the population was 906. It is bordered by the Smith River National Recreation Area. History A post office was opened in 1863. One early settler of Smith River was William Dows Rexford, who moved there with his sons in the early 1870s. The town has formerly been known as Smith River Corners, Smith's River Valley, Smiths River, and Smith's River. Demographics The 2010 United States Census reported that Smith River had a population of 866. The population density was . The racial makeup of Smith River was 528 (61.0%) White, 1 (0.1%) African American, 59 (6.8%) Native American, 5 (0.6%) Asian, 0 (0.0%) Pacific Islander, 234 (27.0%) from other races, and 39 (4.5%) from two or more races.

Mygalomorphae
The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to them forming trapdoors over their burrows. Other prominent groups include Australian funnel web spiders and tarantulas, with the latter accounting for around one third of all mygalomorphs. Description This group of spiders comprises mostly heavy-bodied, stout-legged spiders including tarantulas, Australian funnel-web spiders, mouse spiders, and various families of spiders commonly called trapdoor spiders. Like the "primitive" suborder of spiders Mesothelae, they have two pairs of book lungs, and downward-pointing chelicerae. Because of this, the two groups were once believed to be closely related. Later it was realized that the common ancestors of all spiders had these features (a state known as symplesiomorphy). Following the br ...

Spiders Of The United States
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separat ...
