Armas
The Arma people are an ethnic group of the middle Niger River valley, descended from Moroccan invaders of the 16th century . The name, applied by other groups, derives from the word ''ar-rumah'' ( ar, الرماة) "fusiliers". N. Levtzion, "North-West Africa: from the Maghrib to the fringes of the forest" inThe Cambridge history of Africa, Volume 4 : c.1600-c.1790 Ed. Cambridge University Press (1975), pp.154-155 The Arma ethnicity is distinct from (but sometimes confused with) the 3.6 million Zarma people of western Niger, who predate the Moroccan invasion and speak the Zarma language, also a member of the Songhay languages. As of 1986, there were some 20,000 self-identified Arma in Mali, mostly around Timbuktu, the middle Niger bend and the Inner Niger Delta. The Songhai expedition and aftermath The 1590 expedition sent to conquer the Songhai Empire trade routes by the Saadi dynasty of Morocco was made up of four thousand Moroccan, Morisco refugees and European renega ...

Scorpion
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs, and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their taxonomy is being revised to account for 21st-century genomic studies. Scorpions primarily prey on insects and other invertebrates, but some species hunt vertebrates. They use their pincers to restrain and kill prey, or to prevent their own predation. The venomous sting is used for offense and defense. During courtship, the male and female grasp each other's pincers and dance while he tries to move her onto his s ...

Buthidae
The Buthidae are the largest family of scorpions, containing about 100 genera and 1339 species as of 2022. A few very large genera (''Ananteris'', ''Centruroides'', '' Compsobuthus'', or '' Tityus'') are known, but a high number of species-poor or monotypic ones also exist. New taxa are being described at a rate of several new species per year. They have a osmopolitandistribution throughout tropical and subtropical environments worldwide. Together with four other families, the Buthidae make up the superfamily Buthoidea. The family was established by Carl Ludwig Koch in 1837. Around 20 species of medically important (meaning potentially lethal to humans) scorpions are known, and all but one of these ('' Hemiscorpius lepturus'') are members of the Buthidae. In dead specimens, the spine beneath the stinger, characteristic for this family, can be observed. List of genera and number of species The following genera are recognised in the family Buthidae: * '' Aegaeobuthus'' Kovarik, ...

Centruroides
''Centruroides'' is a genus of scorpions of the family Buthidae. Several North American species are known by the common vernacular name bark scorpion. Numerous species are extensively found throughout the southern United States, Mexico, Central America, the Antilles and northern South America. Some are known for their interesting patterning or large size (among Buthidae); most if not all fluoresce strongly under ultraviolet illumination, except after moulting. They contain several highly venomous species, and fatalities are known to occur. The venom of the Mexican scorpion ''Centruroides limpidus limpidus'' contains the neurotoxins Cll1 and Cll2. Taxonomy The number of species accepted as valid may vary, depending on the authority. The genus is highly speciose, containing at least 100 species: * ''Centruroides alayoni'' Armas, 1999 * ''Centruroides altagraciae'' Teruel, de Armas & Kovarik, 2015 * ''Centruroides anchorellus'' Armas, 1976 * ''Centruroides arctimanus'' Armas, 19 ...
