Chanbria
''Chanbria'' is a genus of camel spiders. It consists of four species found in the Sonoran Desert in Mexico and the southwestern United States. Taxonomy American arachnologist created this genus in 1951. He wrote the generic name (biology), generic name, ''Chanbria'', was an "arbitrary combination of letters based on an anagram of the name Branch", referring to Jefferson H. Branch; Branch had collected the holotype for the type species. Muma did not explicitly designate a grammatical gender, gender, but Australian arachnologist Mark S. Harvey notes that Muma used masculine endings for species in this genus. Muma's 1951 circumscription (taxonomy), circumscription included two newly described species, the type species ''C. regalis'' and ''C. serpentinus''. In 1962, he described two additional species: ''C. rectus'' and ''C. tehachapianus''. In 1970, Muma grouped the four ''Chanbria'' species into two species groups: the ''regalis''-group (''C. rectus'', ''C. regalis'', and ''C. t ...

Malleolus (arthropod)
Malleolus (plural: malleoli) is a fan-shaped chemoreceptor or racquet organ, an array of which are carried in pairs on the ventral or undersides of Solpugidae. They are the counterpart of pectines in scorpions, and modified walking limbs in the uropygids and amblypygids. Most species have 5 pairs of malleoli on the ventral surface of the fourth pair of legs of both sexes, while juveniles and other species have 2-3 pairs.http://www.biodiversityexplorer.org/arachnids/solifugids/ A malleolus comprises a basal stalk and a triangular fan, with epicuticular protrusions on each anterior face, and granular structures on each stalk, with undulate surfaces at each distal end.

Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of life The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') are the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally, chimpanzees and bonobos (genus ''Pan (genus), Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 to 8 million years ago, that is, during the Late Miocene.

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Twentynine Palms, California
Twentynine Palms (also known as 29 Palms) is a city in San Bernardino County, California. Twentynine Palms serves as one of the entry points to Joshua Tree National Park. History Twentynine Palms was named for the palm trees found there in 1852 by Col. Henry Washington while surveying the San Bernardino base line. A post office was established in 1927. A road named Utah Trail honors the late 1800s pioneers on a trail originating in Utah (reportedly Saint George) that went to Twentynine Palms. Nearby is a small Indian reservation belonging to the Twenty-Nine Palms Band of Mission Indians. Joshua Tree National Park, which lies just to the south of Twentynine Palms, was designated a national monument in 1936, and became a national park in 1994. The nearby Marine Corps Air Ground Combat Center Twentynine Palms was founded in 1952. Demographics Its population as of July 1, 2013, was estimated at 25,768. 2010 census At the 2010 census, there were 25,048 people in 8,095 hous ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Barstow, California
Barstow is a city in San Bernardino County, California, in the Mojave Desert of Southern California. Located in the Inland Empire region of California, the population was 25,415 at the 2020 census. Barstow is an important crossroads for the Inland Empire and home to Marine Corps Logistics Base Barstow. History The settlement of Barstow began in the late 1840s in the Mormon Corridor. Every fall and winter, as the weather cooled, the rain produced new grass growth and replenished the water sources in the Mojave Desert. People, goods, and animal herds would move from New Mexico and later Utah to Los Angeles, along the Old Spanish Trail from Santa Fe, or after 1848, on the Mormon Road from Salt Lake City. Trains of freight wagons traveled back to Salt Lake City and other points in the interior. These travelers followed the course of the Mojave River, watering and camping at Fish Ponds on its south bank (west of Nebo Center) or 3.625 miles up river on the north bank, at a riv ...

Hemipteran
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some variations of English, all terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles.

Chelicerae
The chelicerae () are the mouthparts of the subphylum 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 (or are connected to) venom glands, and are used to inject venom into prey or a perceived threat. In ''Pisaurina mira'', also known as the nursery web spider, the chelicerae are 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 (papillae in pseudoscorpions, cheliceral teeth in Opiliones). Types Chelicerae can be divided into three kinds: jackknife chelicerae, scissor chelicerae, and 3-segmented chelate chelicerae. Jackknife chelicerae The jackknife chelicera is subchelate (with ...

Chemoreceptor
A chemoreceptor, also known as chemosensor, is a specialized sensory receptor which transduces a chemical substance (endogenous or induced) to generate a biological signal. This signal may be in the form of an action potential, if the chemoreceptor is a neuron, or in the form of a neurotransmitter that can activate a nerve fiber if the chemoreceptor is a specialized cell, such as taste receptors, or an internal peripheral chemoreceptor, such as the carotid bodies. In physiology, a chemoreceptor detects changes in the normal environment, such as an increase in blood levels of carbon dioxide (hypercapnia) or a decrease in blood levels of oxygen (hypoxia), and transmits that information to the central nervous system which engages body responses to restore homeostasis. In bacteria, chemoreceptors are essential in the mediation of chemotaxis. Cellular chemoreceptors In prokaryotes Bacteria utilize complex long helical proteins as chemoreceptors, permitting signals to travel long di ...

Pedipalp
Pedipalps (commonly shortened to palps or palpi) are the second pair of appendages of chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and anterior to the first pair of walking legs. Overview Pedipalps are composed of six segments or articles: the coxa, the trochanter, the femur, the short patella, the tibia, and the tarsus. In spiders, the coxae frequently have extensions called maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior legs. The limbs themselves may be simple tactile organs outwardly resembling the legs, as in spiders, or chelate weapons ( pincers) of great size, as in scorpions. The pedipalps of Solifugae are covered in setae, but have not been studied in detail. Comparative studies of pedipalpal morphology may suggest that leg-like pedipalps are primitive in arachnids.
