Metriopelma
''Metriopelma'' is a monotypic genus of Mexican tarantulas currently containing the single species, ''Metriopelma breyeri''. It was first described by Léon Becker (1826–1909) in 1878, and originally found by Eugenio Dugès (1834–1895). This tarantula was named after Albert Breyer (1812–1876), a fellow entomologist. It is native to Mexico in the state of Guanajuato. Description Its cephalothorax is brown, a little longer than it is round, with a comparatively narrow forehead. Its sternum is slightly cut on the sides, longer than it is wide, covered with hairs. The chelicerae are reddish, shiny, covered with thick hairs. The abdomen is oval, longer than the cephalothorax, dark brown and hairy. It has sturdy legs, covered with hair, with two small tarsal claws that are reddish and retractile. Transferred to other genera This genus previously included: * ''Metriopelma coloratum'' (now moved to genus ''Hapalopus'') *''Metriopelma velox'' (now moved to genus ''Cymbiapophysa'') ...

Theraphosidae
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. , 1,100 species have been identified, with 166 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder ( Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes. Overview Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support.Pomeroy, R. (2014, February 4). Pub.

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Léon Becker (1826 – 27 January 1909) was a Belgian botanist, painter, naturalist Natural history is a domain of inquiry involving organisms, including animals, fungi, and plants, in their natural environment, leaning more towards observational than experimental methods of study. A person who studies natural history is cal ..., and Arachnology, arachnologist. Biography From a young age, he became passionate about entomology, with a particular interest in arachnology. He is the author of the first studies on Belgian spiders. Between 1882 and 1896, he published four volumes entitled ''Les Arachnides de Belgique'', which he illustrated himself. His lithographs are of very high quality. He also studied Dutch, German, Moldavian, and Hungarian fauna.
